Climate 101: Deforestation

Forests cover about 30 percent of the planet's land mass, but humans are cutting them down, clearing these essential habitats on a massive scale. What is deforestation? Find out the causes, effects, and solutions.

As the world seeks to slow the pace of climate change, preserve wildlife, and support more than eight billion people, trees inevitably hold a major part of the answer. Yet the mass destruction of trees—deforestation—continues, sacrificing the long-term benefits of standing trees for short-term gain of fuel, and materials for manufacturing and construction.

We need trees for a variety of reasons, not least of which is that they absorb the carbon dioxide we exhale and the heat-trapping greenhouse gases that human activities emit. As those gases enter the atmosphere, global warming increases, a trend scientists now prefer to call climate change.

There is also the imminent danger of disease caused by deforestation.
