The main problem facing the environment at the moment is of course climate change. But there is another massive challenge nature is facing - species are dying out at an incredible rate because of habitat loss. The main reason for this is deforestation, but how can we fight to stop it?
The primary reason for deforestation is to make way for farms. We're chopping down millions of acres of forest to create grazing land for cattle or arable land for crops. All this to feed the ever increasing human population, already in the billions. But what good is food if we can't breathe? Forests not only provide us with oxygen, they also cleanse carbon dioxide from the atmosphere, and so help to tackle global warming.
Three-quarters of land animals live in forests and we're removing their homes for purely selfish reasons. And it's not just animals - countless species of tropical plant have become extinct before we even discovered them.
