Threats To Tropical Rainforest Ecosystems And How They Can Be Managed
Gbogbo ọrọ náà
An area of tropical rainforest the size of many football pitches is cleared every minute, mostly for farming, ranching, logging and mining. Because the forest's nutrients live in the trees rather than the soil, clearing it does lasting damage: the land turns infertile fast, biodiversity is lost and carbon is released into the atmosphere.
This lesson examines what threatens tropical rainforests, the impacts of deforestation on the environment and on people, and how rainforests can be managed sustainably. It is anchored in a detailed case study of the Amazon in Brazil, with the Danum Valley in Borneo as a conservation example, so you can support your answers with named, specific facts.
