Unscramble the Blue Letters

We have in the wrold about four billion hectares of forests. This is more or less China, U.S., Canada and Brazil all together, in terms of size, to have an idea. Three quarters of that is in the temperate zone, and just one quarter is in the tropics, but this one quarter, one boillin hectares, hldos most of the biodiversity, and very importantly, 50 percent of the living biomass, the carbon. Now, we used to have six billion hectares of forest — 50 percent more than what we have — 2,000 years ago. We've actually lost two billion hectares in the last 2,000 years. But in the last 100 years, we lost half of that. That was when we sfehtid from deforestation of temperate forests to deseotofriatn of tropical forests.

We have in the world about four billion hectares of forests. This is more or less China, U.S., Canada and Brazil all together, in terms of size, to have an idea. Three quarters of that is in the temperate zone, and just one quarter is in the tropics, but this one quarter, one billion hectares, holds most of the biodiversity, and very importantly, 50 percent of the living biomass, the carbon. Now, we used to have six billion hectares of forest — 50 percent more than what we have — 2,000 years ago. We've actually lost two billion hectares in the last 2,000 years. But in the last 100 years, we lost half of that. That was when we shifted from deforestation of temperate forests to deforestation of tropical forests.
