It’s not the only major forest under assault. Nearly half of the world’s forests that stood when humans started farming are now gone, and each year an additional 32 million acres are destroyed, according to the nonprofit Rainforest Alliance. The biggest reason is expansion of agriculture into forested areas. In Brazil it’s cattle ranching, soy production and logging, according to Nigel Sizer, tropical forest ecologist and chief program officer with the Rainforest Alliance. “It is responsible for 80% to 90% of the loss of tropical forests around the world.” Environmental groups say these activities can be slowed or done in a much more sustainable way.
“There has been a lot of analysis and satellite data that shows there is so much land already cleared – a lot abandoned or very poorly used and managed that we could use to grow food on,” says Sizer. “We don’t need to be clearing new forests to do this in Brazil.”
Here’s what you can do to help slow forest loss.
Make sure products you buy are “rainforest safe”
Take steps to live sustainably
As major forests decrease in size, carbon and greenhouse gases have increased in the atmosphere. But you can help slow that trend.
“Think about greenhouse gas emissions — driving less, buy a more fuel efficient car,” Sizer says. He also recommends adjusting your thermostats by just a couple of degrees. “It makes a huge difference and saves money as well.”
You can also buy carbon offsets. “If you have to fly for work often — you can buy these offsets by making a small contribution to an organization that is planting trees, sucking up carbon that’s being emitted when you fly. These things really add up.”
About 20% of the Amazon has already been destroyed, and that’s what scares Sizer. “The newest science now says if we deforest, if there’s a clearing of more than about 30% to 40% of the Amazon rainforest, it will start to dry out. We’ll pass an irreversible tipping point.”
