Nature Needs Half recognizes that half is, in many cases, an approximation. Some ecoregions need a little less to survive, others need far more. The Amazonian rainforest consists of fragile ecology that, once disturbed, is nearly impossible to replace. In the case of Brazil, nature needs more than half.

Brazil's Ecology

The Amazon Basin is equivalent in size to the 48 contiguous United States and is home to over one-third of all species on the planet. Protecting an area this size (especially when it comes to ensuring that those protections are enforced) requires broad commitment on the part of governments, grassroots groups, businesses, and Indigenous Peoples. And in the case of the Amazon, protecting more than 70% of this region is necessary to keep its ecological functions intact. Building strong coalitions for (at least) half in Brazil is crucial for the survival of one of our planet’s most precious ecoregions.

Half (Mission Achieved)

Ecologically intact & protected landscapes comprise 50% or more of this country.

Can Reach Half

Intact landscapes lacking protected status comprise 50% or more of this country.

Could Be Restored

Between 20-40% of landscapes are still ecologically intact.


Less than 20% of the natural ecology of this area is intact.
