Final answer:
The greatest rate of deforestation is in South America, especially in the Amazon basin of Brazil. Other regions such as Central America, Southeast Asia, and Africa also face significant deforestation.
Step-by-step explanation:
The greatest rate of deforestation is currently taking place in South America, particularly in the Amazon basin. Brazil's Amazon has seen significant deforestation, with Rondônia losing about half of its forest since 1990. Other tropical regions such as Central America, Southeast Asia, and Africa are also facing critical rates of deforestation due to agricultural expansion, logging, and other human activities. In contrast, countries in North America and Europe have experienced deforestation historically but have now achieved more stable forest conditions due to economic development and the substitution of forest exploitation with other resources or imports.
