“Importance and Value of Trees”

tree1

Since the beginning, trees have furnished us with two of life’s essentials, food and oxygen. As we evolved, they provided additional necessities such as shelter, medicine, and tools. Today, their value continues to increase and more benefits of trees are being discovered as their role expands to satisfy the needs created by our modern lifestyles.

Here, some important benefits of the trees that you probably didn’t know:

  1. An acre of nature trees absorbs the amount of CO2 produced when you drive your car 42.000 Km.
  1. An acre of nature trees provides enough oxygen for 18 people.
  1. Trees reduce UV-B exposure by about 40 percent.
  1. The evaporation from a single tree can produce the cooling effect of 10 room size air-conditioners operating 20 hours a day.
  1. A well placed tree can reduce noise by as much as 40 percent.
  1. One large tree can supply a days’ supply of oxygen for 4 people.
  1. A healthy tree can store 6 kg of carbon each year.
  1. An acre of trees can store 2.6 tons of carbon dioxide each year.
  1. For every 16.000 km you drive, it takes 7 trees to remove the amount of carbon dioxide produced.
  1. A hundred million new trees would absorb 18 million tons of CO2 and cut air-conditioning cost by 84 billion annually.
  1. A belt of trees 40 meters wide and 12 meters high can reduce highway noise by 40 percent.
  1. A tree can absorb as much as 24 kg of CO2 per year and can sequester on ton of CO2 by the time it reaches 40 years old.
  1. A mature tree can have an appraised value between 1.000$ and 10.000$ council of Tree and Landscape Appraisers.
  1. About 20 percent of the worlds’ emissions are a result of deforestation.
  1. CO2 worlds’ emission is 35.000.000 metric tons per year.
  1. CO2 sequestration is 25 kg per tree per year.
  1. One half the dry weight of wood is carbon.
  1. One person emit 20 ton of CO2 per year.

So, what you have to do is “take action”, and just plant a tree. It is so simple, but so important!! Protect the environment!! Do not destroy it!!

Forests and their Benefits

DSC_0001

The importance of forests cannot be underestimated. Specifically, we depend on forests for our survival, from the air we breathe to the wood we use. Besides providing habitats for animals and livelihoods for humans, forests also offer watershed protection, prevent soil erosion and mitigate climate change.

Here, there are some examples of the importance of plants:

  1. Plants combat climate change: Plants absorb CO2 removing and storing carbon, while releasing the oxygen into the air.
  1. Plants clean the air: Plants absorb odors and pollutants gases (nitrogen, oxides, ammonia, sulfur dioxide, and ozone) and filter particules out of the air by trapping them on the leaves and back.
  1. Plants prevent water pollution: Plants reduce runoff by breaking rainfall thus allowing the water to flow down the trunk and into the earth below the tree. This prevents strormwater from carrying pollutants to the ocean. When mulched trees act like a sponge that filters this water naturally and uses it to recharge groundwater supplies.
  1. Plants help prevent soil erosion: On hillsides or stream slopes tress slow runoff and hold soil in place.
  1. Plants regulate the water cycle: By absorbing and redistribuing rainwater quite equal to every species living within its range.
  1. Plants provide food: Aside from fruits for humans, trees provide food for birds and wildlife.
  1. Plants provide medicine material: Huge amount of different medicine material and drugs we use are extracted from plants, as well as the drugs used to fight cancer.
  1. Plants provide clean water: By slowing rainwater so that it can be absorbed into the ground, plants help filter pollutants and sediment from our water’s while replenishing aquifers and keeping annual stream flows steady.
  1. Plants provide perfect habitat: Plants provide perfect habitat for life to flowrish on lands, containing up to 90% of the planet’s species life.
  1. Plants control floods: Plants can hold vast amount of water that would other ways stream down hills and surge along rivers into towns. That is why plants are such an important part of stormwater management for many cities.
  1. Plants enrich the soil: By recycling the nutrients throw the shedding of leaves and seeds.
  1. Plants control the temperature: The shade and wind-breaking qualities that trees provide, benefit every one from the individual taking sheltrer from a hot summer day to entire cities.
  1. Plants combat global warming: It result from leaf transpiration generating moisture that rise to the atmosphere, forming clouds which release water as rain or other precipitation.
  1. Plants protect from UV-RAYS: Trees reduce UV-B exposure by about 50 percent, thus providing protection to children on school campuses and playgrounds and to all us on the beaches.
  1. Plants heal: Studies have shown that patient with views of trees out of their windows heal faster and with less complications.
  1. Plants are our life: Plants transform solar energy into foods and supply the oxygen we need to survive as well as produce water vapour absorb carbon dioxide and store carbon.

However, today we are experiencing a tragedy, as there is a loss of 13 million hectares of forests every year via deforestation.

Soil erosion and degradation: a global problem – Effects (Part 2)

drought-mud-feather-dry-nature-soil-erosion

The consequences of soil erosion are primarily centered on reduced agricultural productivity, as well as soil quality. But also, water ways may be blocked, and it may affect water quality. This means, most of the environmental problems the world face today, arises from soil erosion.

Particularly, the effects of soil erosion go beyond the loss of fertile land. In other words, it has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.

So, the effects of soil degradation include:

  1. Loss of arable land: Lands used for crop production have been substantially affected by soil erosion. Soil erosion eats away the top soil which is the fertile layer of the land and also the component that supports the soil’s essential microorganisms and organic matter. In this view, soil erosion has severely threatened the productivity of fertile cropping areas as they are continually degraded. Because of soil erosion, most of the soil characteristics that support agriculture have been lost, causing ecological collapse and mass starvation.
  1. Water Pollution and Clogging of Waterways: Soils eroded from agricultural lands, carry pesticides, heavy metals, and fertilizers which are washed into streams and major water ways. This leads to water pollution and damage to marine and freshwater habitats. Accumulated sediments can also cause clogging of water ways and raises the water level leading to flooding.
  1. Increased flooding: Land is commonly altered from its natural landscape when it rids its physical composition from soil degradation. In other words, soil degradation takes away the soil’s natural capability of holding water thus contributing to more and more cases of flooding.
  1. Drought and Aridity: Drought and aridity are problems highly influenced and amplified by soil degradation. As much as it’s a concern associated with natural environments in arid and semi-arid areas, the UN recognizes the fact that drought and aridity are anthropogenic induced factors especially as an outcome of soil degradation. Hence, the contributing factors to soil quality decline such as overgrazing, poor tillage methods, and deforestation are also the leading causes of desertification characterized by droughts and arid conditions.
  1. Destruction of Infrastructure: Soil erosion can affect infrastructural projects such as dams, drainages, and embankments, reducing their operational lifetime and efficiency. Also, the silt up can support plant life that can, in turn, cause cracks and weaken the structures. Soil erosion from surface water runoff often causes serious damage to roads and tracks, especially if stabilizing techniques are not used.
  1. Desertification: Soil erosion is also responsible for desertification. It gradually transforms a habitable land into deserts. The transformations are worsened by the destructive use of the land and deforestation that leaves the soil naked and open to erosion. This usually leads to loss of biodiversity, alteration of ecosystems, land degradation, and huge economic losses.

Finally, we all understand that the erosion of the soil is a very serious issue, especially in our days. That is why we need to take action and prevent the unpleasant effects.

«Wind Power: Advantages and Disadvantages»

wind-turbines17

Wind power is the ability to make electricity using the air flows that occur naturally in the earth’s atmosphere. In other words, is the use of air flow through wind turbines to mechanically power generators for electric power.

Wind power, as an alternative to burning fossil fuels, is plentiful, renewable, clean, and produces no greenhouse gas emissions during operation, consumes no water, and uses little land. Specifically, harnessing energy from the wind and turning it into renewable electricity has many advantages, not only for the environment, but also for the area itself.

Here, some advantages of wind power:

  • Wind power is a clean fuel source:

Wind power doesn’t pollute the air, like the use of coal or oil. Wind turbines don’t produce atmospheric emissions that increase health problems like asthma or create acid rain or greenhouse gases. As a result, wind energy lessens our reliance on fossil fuels from outside nations as well, which helps our national economy and offers a variety of other benefits as well.

  • Wind power is cost-effective:

It is one of the lowest-cost renewable energy technologies available today. Wind turbines can give energy to numerous homes, and people can buy their power from a service organization that offers wind energy for a specific area.

  • Wind power is inexhaustible:

Wind is actually a form of solar energy. Specifically, winds are caused by the heating of the atmosphere by the sun, the rotation of the Earth, and the Earth’s surface irregularities. For as long as the sun shines and the wind blows, the energy produced can be harnessed to send power across the grid.

  • Wind turbines can be built on existing farms or ranches:

This benefits the economy in rural areas, where most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the ground. Also, wind power plant owners make rent payments to the farmer or rancher for the use of the land, providing landowners with additional income.

  • Wind power increases energy security:

By using wind energy to generate electricity, we are reducing our dependency on fossil fuel alternatives such as coal, oil and gas. In many cases, these natural resources are often sourced from other countries, which can fluctuate the price and cause serious economic problems or supply shortages for some countries. By using renewable energy sources, a country can help to reduce its dependency on global markets and increase its energy security.

  • Job Creation:

The wind energy industry has helped to create jobs all over the world. Jobs have been created for the manufacture of wind turbines, the installation and maintenance of wind turbines and also in wind energy consulting. This is an element very important for the economy of the region.

However, there are also some disadvantages that should be mentioned:

  • Threat to Wildlife:

Wind turbines pose a threat to wildlife, especially for birds and other flying creatures that may be in the area. So, this is a serious problem, because wind turbines are contributing to mortality rates among bird and bat population.

  • Noise and Visual pollution:

One of the disadvantages of wind turbines is the noise pollution, that they generate. A single wind turbine can be heard from hundreds of meters away. For example, wind turbines make a sound that can be between 50 and 60 decibels.

Also, there is the problem of visual pollution. Many people think that the wind turbines remain unattractive, as they have concern that it may tarnish the beauty of landscapes.

  • Expensive to set up :

The installation of a wind turbine is considered expensive. If we add also the cost of the supplies that will be need, the problem is becoming greater.

So, taking into consideration all the above, it is clearly understood that this new source of energy has both, advantages and disadvantages. As a result, we have to be careful and to make the best choices.

What do you think about it? Do we have to follow the example of wind power on not?

The future of forests under climate change.

Monier_ERL_Photo

Study projects vast regional differences in forest productivity, migration and wildfire impacts.

Accounting for nearly one-third of the global land surface, forests help regulate the climate and protect watersheds while providing consumer products and outdoor experiences that enhance the quality of life. Climate change will inevitably influence forests’ ability to deliver these services, but past studies have provided a limited picture of what changes may come this century. Now researchers from the Corvallis Forestry Sciences Laboratory, MIT, Ohio State University and the U.S. Environmental Protection Agency have sharpened that picture by assessing the impact of climate change on three key factors: forest productivity (capacity to extract, store and transform atmospheric carbon dioxide into forest products), migration (geographical shifts of vegetation) and wildfire-induced depletion and regrowth.

Using a combined global vegetation and climate model to compare two climate policy scenarios—a “business-as-usual” scenario in which greenhouse gas emissions are unconstrained, and a “2°C” scenario representing an emissions pathway that would limit the rise in global mean temperature since preindustrial times to two degrees Celsius by 2100—the researchers determined that the impact of climate change on forests in the coming decades is decidedly mixed.

Both scenarios project a net increase in forest carbon stocks across the globe, with most of the gains occurring in tropical forests. The business-as-usual scenario would raise concentrations of atmospheric carbon dioxide substantially, increasing the fertilization effect of CO2, leading to higher vegetation growth and carbon stocks. But because increased CO2 leads to higher surface temperatures, some of these gains would be counteracted by a higher incidence of wildfires, particularly in temperate zones, which release CO2 into the atmosphere as they consume trees and other forest plants. The 2°C climate mitigation scenario, which significantly decreases atmospheric CO2, would, in turn, reduce these forest carbon stock gains, especially in the southern hemisphere.

While unconstrained climate change would likely benefit forests at the global level and in some regions, it would decrease forested areas in many others, particularly in Russia, Canada and China. Wildfires would multiply with increasing temperatures, especially in Russia and Central America. In Russia, climate change would significantly decrease carbon stocks and forest areas while increasing burnt forest areas.

“While climate mitigation would reduce carbon stocks globally, it would also reduce wildfire damages to forests and the adaptation costs associated with those damages,” says Erwan Monier, a co-author of the study and principal research scientist at the MIT Joint Program on the Science and Policy of Global Change. “By minimizing uncertainty about future forest health and productivity, climate mitigation would lower the complexity and expense of future forestry sector management and planning.”

The study, which was primarily funded by the EPA, appears in the journal Environmental Research Letters. (A companion paper published in the same journal used this study’s results to evaluate the economic impacts of climate change on the forestry sector.)

To assess the impact of climate change on forests under different climate scenarios, the researchers used a dynamic global vegetation model under multiple climate simulations from a version of the MIT Integrated Global Systems Modeling (IGSM) framework that incorporates the Community Atmosphere Model. They arrived at their “business-as-usual” and “2°C” scenario projections by tracking changes in forest carbon stocks, total forest area and burnt forest area in 16 geographical regions over the course of the 21st century.

As lead climate scientist of the study, Monier sought to examine the precision of these projections. Recognizing three key sources of uncertainty in climate change impacts on the world’s forests—emissions scenarios, the global system climate response (climate sensitivity) and natural variability (year-to-year and longer-term variations in the climate), the researchers ran large numbers of simulations of each scenario to understand the impact of these sources of uncertainty on their estimates.

“The problem of Deforestation: causes, effects and possible solutions”

deforestation_2074483b

Deforestation, clearance or clearing is the removal of a forest or stand of trees, often resulting in damage to the quality of the land. Through agriculture and logging, mining and climate change, humans are wiping out irreplaceable forests – and the life that depends on them, face a lot of problems. We are losing not only our primeval forests, which regulate our climate and water resources, but also the amazing range of species that call them home.

For example, the biggest driver of deforestation is “agriculture”, where the farmers cut forests to provide more room for planting crops or grazing livestock. Also, “logging operations”, which provide the world’s wood and paper products, cut countless trees each year. As a result, the problem is becoming more and more serious and the people are not trying to do something, in order to deal with it.

It is very important to understand “how serious the problem is”, especially in terms of the environment.  To make it clear, it is widely accepted that one of the most dramatic impacts is the loss of habitat for millions of species. Eighty percent of Earth’s land animals and plants live in forests, and many cannot survive the deforestation that destroys their homes. They lose their habitat and are forced to move to a new location, while some of them are even pushed to extinction. So, our world has lost so many species of plants and animals in last couple of decades.

In addition to the loss of habitat, the lack of trees also allows a greater amount of greenhouse gases to be released into the atmosphere.  In other words, with constant deforestation, the ratio of green house gases in the atmosphere has increased, adding to our global warming woes. As a result, not only the humans are facing a lot of health problems, but also we observe a deterioration of the problem of global warming.

Further effects of deforestation include soil erosion, because with the clearance of tree cover, the soil is directly exposed to the sun, making it dry. Here, we have to add also the problem of “floods”. In particular, when it rains, trees absorb and store large amount of water with the help of their roots. When they are cut down, the flow of water is disrupted and leads to floods in some areas and droughts in other. 

So, the question is “what we can do to prevent deforestation”?

Some possible solutions:

  • Law and regulations

The best solution to deforestation is to curb the felling of trees, by employing a series of rules and laws at governmental and organizational levels. Laws on timber, wood fuel, farming, and land use among other forest resources must be advanced and enforced to limit deforestation.

  • Replanting – Reforestation

People, communities, governments, and organizations are all active actors. Reforestation involves selecting and dedicating large tracts of land mainly for the purpose of cultivating forests. For instance, in local communities and urban centers, it can be done around market areas, or within city parks.

  • Green Business

Green methods of production and utilization of resources can immeasurably reduce deforestation. Particularly, it’s the focus on re-using items, reducing the use of artificial items, and recycling more items.  By focusing on recycling paper, plastics, and wood products, it means there will be less dependence on the natural resources and trees.

  • Sensitization and Educative Campaigns

By organizing a campaign so as to inform the public, we can achieve positive results. In this way, people will be able to detect the causes, effects, and ways of counteracting deforestation. In addition, sharing information with people including family, friends, colleagues, and the entire community on deforestation and its effects, is an appropriate measure of standing up in unison to combat the clearing of forests.

So, it is very important to understand the seriousness of the problem and, by extension, to take action. It is not obligatory to follow the above ways of dealing, but you can alone discover new methods and contribute in a better future.

Take action! Be positive! Change the world!

Η σημασία των δασών και ο ρόλος του ανθρώπου

dasos

Όπως όλοι γνωρίζουμε, η προστασία του Περιβάλλοντος αποτελεί ένα ζήτημα ύψιστης σημασίας, παρά την εκάστοτε αδιαφορία που δείχνουμε κατά καιρούς. Συγκεκριμένα, το φυσικό περιβάλλον μέσα στο οποίο ζει ο άνθρωπος, είναι πρωταρχικής σημασίας, τόσο για την υγεία του, όσο και για την ανάπτυξη και ευημερία του.  Ωστόσο, παρατηρείται μία παράλογη καταστροφή του περιβάλλοντος, με υπεύθυνο τον ίδιο τον άνθρωπο. Η άγνοια, η αδράνεια, σε συνδυασμό με τις διάφορες δραστηριότητες του, οδηγούν στην καταστροφή του περιβάλλοντος.

Μολονότι, με την έννοια φυσικό περιβάλλον εννοείται η φύση γύρω μας, τα δέντρα, το νερό, ο αέρας, το φως και γενικότερα όλα αυτά τα στοιχεία που είναι πολύ σημαντικά για να ζήσει ο άνθρωπος, παρατηρείται μια καταστροφή αυτού του «μεγάλου σπιτιού», κάτι που θα πρέπει να αλλάξει, διότι τα θετικά στοιχεία τα οποία μας παρέχονται είναι πολύ σημαντικά.

Ένα από τα πιο σοβαρά ζητήματα είναι η «καταστροφή των δασών». Κάθε χρόνο, παρατηρείται μία αύξηση των περιστατικών, όπου τεράστιες εκτάσεις δασών εξαφανίζονται, είτε λόγω πυρκαγιών, είτε από εκκοπή ξυλείας, είτε από εκχερσώσεις για οικόπεδα, αεροδρόμια κτλ.

Γι’ αυτό το λόγο, θα πρέπει να συνειδητοποιήσουμε ότι το δάσος είναι ένα σύνολο πολυσύνθετο με δική του ζωή και με ξεχωριστή θέση, ρόλο και σημασία μέσα στη φύση και με τεράστιες δυνατότητες, που θα πρέπει να αξιοποιηθούν σωστά.

Ειδικότερα, τα δάση παίζουν πολύ σημαντικό ρόλο, διότι παράγουν το απαραίτητο και αναντικατάστατο για την ζωή μας οξυγόνο, και συγχρόνως δεσμεύουν το επικίνδυνο για την ζωή διοξείδιο του άνθρακα, ενώ αποτελούν και πηγή τροφίμων, φαρμάκων και καθαρού νερού, απαραίτητο στοιχείο για τον άνθρωπο και κατ’ επέκταση για τη διαβίωσή του. Επιπρόσθετα, παρέχουν ένα ευρύ φάσμα περιβαλλοντικών υπηρεσιών, συμπεριλαμβανομένης της διατήρησης της βιοποικιλότητας, την υδροδότηση, τον έλεγχο των πλημμύρων, καθώς και την προστασία από τη διάβρωση του εδάφους και της απερήμωσης. Παράλληλα, συμβάλλουν στη διατήρηση ενός σταθερού κλίματος του πλανήτη και του περιβάλλοντος, ενώ είναι και ζωτικής σημασίας, όπως προαναφέρθηκε, για την επιβίωση και την ευημερία των ανθρώπων.

Ο άνθρωπος συνδέθηκε με το δάσος από την πρώτη στιγμή της εμφάνισής του πάνω στη γη και μάλιστα στενότατα, καθώς, του εξασφάλισε τροφή, στέγη, προστασία, ψυχαγωγία και εργασία. Του πρόσφερε την απαραίτητη ξυλεία, τα καυσόξυλα και τα άλλα δασικά προϊόντα (καρπούς, ρετσίνι κ.ά.) για τη διαβίωση και την πρόοδό του, ενώ του έδωσε επίσης και ευκαιρίες και δυνατότητες για κοινωνικές, θρησκευτικές, καλλιτεχνικές και άλλες εκδηλώσεις και απασχολήσεις για την πνευματική, κοινωνική και πολιτιστική του άνοδο.

Το δάσος, στο πέρασμα των αιώνων, συνεχίζει να προσφέρει όλα αυτά τα θετικά στοιχεία, παρά τη συμπεριφορά του ανθρώπου, γεγονός που μας υπενθυμίζει ότι θα πρέπει να αξιοποιήσουμε με τον καλύτερο τρόπο αυτή την πολύτιμη και αστείρευτη φυσική πηγή ζωής, συμβάλλοντας στην προστασία του και κατ’ επέκταση παίρνοντας σημαντικά μέτρα για τη διασφάλισή του, ξεκινώντας με την ενημέρωση του κοινού για τη σημασία και την προσφορά των δασών, αλλά και γενικότερα, όλου του φυσικού περιβάλλοντος.

Humans on the verge of causing Earth’s fastest climate change in 50m years

926

A new study published in Nature Communications looks at changes in solar activity and carbon dioxide levels over the past 420 million years. The authors found that on our current path, by mid-century humans will be causing the fastest climate change in approximately 50 million years, and if we burn all available fossil fuels, we’ll cause the fastest change in the entire 420 million year record.

The study relates to a scientific conundrum known as the faint young sun paradox – that early in Earth’s history, solar output was 30% less intense than it is today, and yet the planet was warm enough to have a liquid ocean. A stronger greenhouse effect due to higher carbon dioxide levels in the atmosphere may be one explanation.

Over time, solar output has grown stronger, and atmospheric carbon dioxide levels have fallen due to an effect known as “weathering” of rocks and an increase in plant life. The authors of this study found that over the past 420 million years, the slow heating of the sun and slow decline of the greenhouse effect have roughly offset each other, leading to a fairly stable long-term global climate.

Millions of native oysters to be returned to the Solent

5409

New project aims to restore what was once Europe’s largest oyster fishery, off the south coast of England. Millions of native oysters are to be put into the Solent, once the site of Europe’s largest oyster fishery.

The five-year project aims first to restore a thriving oyster population to the waters between the south coast and Isle of Wight. Oyster beds provide habitat for many other species and the shellfish filter vast volumes of water – 200 litres per oyster – helping to clean up pollution. Once re-established, significant oyster fishing could resume.

A million young oysters will be put into the Solent in 2017, in places where they cannot be legally fished. A further 10,000 are being put in special cages in harbours, from where they can send out larvae.

Oysters have been fished in the UK since at least Roman times and at its peak in the 1920s 40 million oysters were eaten each year, with the abundance leading to the mollusc being known as a poor man’s food. But by the 1960s this had fallen to 3 million oysters a year.

The population in the Solent crashed again recently, with the annual catch falling from 200 tonnes in 2007 to just 20 tonnes in 2011 – about 250,000 shells – and oyster fishing was banned in the Solent in 2013. “It’s a perfect storm of overfishing, habitat destruction, dredging, climate change, disease, invasive species and quite possibly pollution,” said Preston, a marine biologist at the University of Portsmouth who is monitoring the project.

Forest Does Not Only Absorb CO2 But Affects Cooling Of Earth Too

tree-trunks

Researchers have found out that forest and trees do not only absorb the carbon dioxide emissions of the world, but they cool the Earth in other ways too. The study, which was published in the journal “Nature Climate Change”, has stated that lawmakers and legislators should really think about the forest and what they are doing to them. Trees and the forest affect the climate change big time as they affect not only the atmosphere but other parts of the world too, said the authors of an international study.

After collecting the meteorological data and the data satellites the scientists found out that there is a big difference between the farming areas and the forested areas. The cooling effects in plain fields are lower than in the areas with trees and in the forest. That was not a surprise for the researchers at all. “Forests play a more important role in cooling the surface in almost all regions of the Earth than was previously thought,” said study co-author Kaiguang Zhao, assistant professor of environment modeling and spatial analysis at The Ohio State University. “This really affirms the value of forest conservation and protection policies in the fight against climate change,” Zhao added.

What was shocking was the forest and the trees also cool down the mid and lower altitude levels of the Earth as much as how they cool the higher areas.
