Invest in forests and indigenous people to fight climate change – experts

Efforts to protect carbon-absorbing forests, which could have a massive impact on reducing global warming, only attract a tiny fraction of the billions of dollars spent on cutting emissions, experts said, as they called for greater investment. Almost 40 times more money has been spent on promoting agriculture and land development – which have led […]

Urban and Suburban Green of Attica. How much it is and how it should be.

Urban green is defined as the vegetation of the cities, usually consisting of small or large groves, parks, playgrounds, private gardens, etc. and generally concerns the green that provided by the various private or public spaces. By the term “suburban green”, as there is no official terminology, we refer to the free, green land – […]

Which Trees Offset Global Warming Best?

Trees are important tools in the fight to stave off global warming, because they absorb and store the key greenhouse gas emitted by our cars and power plants, carbon dioxide (CO2), before it has a chance to reach the upper atmosphere where it can help trap heat around the Earth’s surface. All Plants Absorb Carbon […]

First-ever ‘negative emissions’ power plant goes online

Unfortunately, it’s no longer enough to cut CO2 emissions to avoid further global temperature increases. We need to remove some of the CO2 that’s already there. Thankfully, that reversal is one step closer to becoming reality. Climeworks and Reykjavik Energy have started running the first power plant confirmed to produce “negative emissions” — that is, […]

Funding Trees for Health

Imagine if there were one simple action that city leaders could take to reduce obesity and depression, improve productivity, boost educational outcomes and reduce incidence of asthma and heart disease among their residents. Urban trees offer all these benefits and more. Yet American cities spend less than a third of a percent of municipal budgets […]

These drones can plant 100,000 trees a day

It’s simple maths. We are chopping down about 15 billion trees a year and planting about 9 billion. So there’s a net loss of 6 billion trees a year. Hand planting trees is slow and expensive. To keep pace with the tractors and bulldozers clearing vast areas of land, we need an industrial-scale solution. For […]

Floating Tar, Dead Fish: Oil Spill Threatens Greek Beaches

The Greek authorities scrambled on Thursday to clean up fuel leaked by an oil tanker that sank near Athens, putting popular beaches off limits to swimmers and raising fears of environmental damage. The Agia Zoni II, a 45-year-old oil tanker, sank near the island of Salamis, about seven miles from the country’s main port, Piraeus. […]

“Importance and Value of Trees”

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. […]

Forests and their Benefits

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 […]
