Decades of poor management, pollution and overconsumption have thrown our water systems out of balance. And climate change is exacerbating the problem. At the current rate of water use, by 2050, more than half of the world’s population will be at risk of water shortages, according to Make Every Drop Count , a 2018 report from the United Nations and the World Bank on the global water crisis.
Forests are our strongest allies in securing the freshwater resources life depends on. It is common knowledge that tree roots suck water from the soil to survive. But what is less known is the “rainmaker” role that trees play.
Forty percent of our planet’s annual rainfall come from evapotranspiration, which happens when trees “exhale” moisture through their leaves. The mist this creates can be seen by satellites all the way in outer space.
