Heatwaves are one of the world’s most underestimated threats, killing more than 12,000 people every year around the world, more than any other weather-related event. And heat is especially dangerous in cities, which tend to be much warmer than surrounding less-developed areas. On top of that, cities tend to have higher levels of air pollution, which contribute to more than 3 million deaths every year. With 70 percent of the world’s population predicted to live in cities by 2050, heat and air pollution constitute a major public health concern.
One relatively simple solution to this problem? Plant more trees in cities. Trees cool the air by casting shade and releasing water vapor, and their leaves can filter out fine particulate matter (PM)—one of the most dangerous forms of air pollution, generated from burning biomass and fossil fuels.
So, take action by planting a tree. It is so simple, but very important.

Arid Zone AfforestationNPO (AZA) is a non-profit organization that acts to combat desertification on a local and global level, in arid, semi-arid, and deserted regions, where rainfall is limited or non-existent, by the use of innovative, environmentally friendly planting technologies, such as the Safe TreeΤΜ planting system.
