Plants live off carbon dioxide, but a higher level of the greenhouse gas in the air doesn't necessarily lead to more biomass production.
Restoring tropical rainforests is good for the climate, wild species and humans. But where to start? A new study pinpoints locations that will maximize benefits and minimize negative impacts.
Many nations are restoring degraded tropical forests to slow climate change, protect endangered species and improve rural life. But those forests often are cleared again soon afterward.
Brazil has set itself a target of restoring almost 50,000 sq km of the Amazon rainforest by 2030. But it won't get there without changing its policies and how it engages with local people.
