Deforestation and Forest Loss
Globally, we deforest around ten million hectares of forest every year.11 That's an area the size of Portugal every year. Around half of this deforestation is offset by regrowing forests, so overall, we lose around five million hectares each year. Nearly all — 95% — of this deforestation occurs in the tropics.
