More than 4 billion hectares of our planet are covered by forests - that’s around 30% of it's land surface. As you can imagine, forests are kind of an important global resource. When we clear lands, another expression to say “cut trees down”, we’re boosting climate change and global warming, and causing critical damage to plant and animal species. This includes us, humans.
If we continue to deforest at the pace we’re doing it at right now, we won’t be able to recover from the effects driven by all the harm we do, and will do to key ecosystems and biodiversity. Don’t forget that, as we talked about in other articles, forests are also necessary to balance the levels of carbon dioxide that are released into the atmosphere.
