How are humans affecting the biodiversity of the Amazon when we cut down trees?

Summary: The human impact on the Amazon rainforest has been grossly underestimated according to an international team of researchers. They found that selective logging and surface wildfires can result in an annual loss of 54 billion tons of carbon from the Brazilian Amazon, increasing greenhouse gas emissions.

Increased flooding due to a lack of water absorption by trees.

What is deforestation and its impact on environment?

Deforestation not only affects the climate by increasing the atmospheric level of carbon dioxide but also affects the environment by inhibiting water recycling, triggering severe flooding, aquifer depletion, soil degradation and the extinction of plant and animal species.

Why is deforestation so bad?

Deforestation and the destruction of forest habitat is the leading cause of extinction on the planet. … On top of that, the capacity of forests to pull greenhouse gases from the atmosphere is lost as forests are cut. Forest loss contributes about 15-20% of all annual greenhouse gas emissions.
