NEET BIOLOGY

Detailed explanation-1: -Trees are cut down for timber, waiting to be transported and sold. Deforestation is the purposeful clearing of forested land. Throughout history and into modern times, forests have been razed to make space for agriculture and animal grazing, and to obtain wood for fuel, manufacturing, and construction.

Detailed explanation-2: -More than half of Earth’s rain forests have already been lost due to the human demand for wood and arable land. Rain forests that once grew over 14 percent of the land on Earth now cover only about 6 percent.

Detailed explanation-3: -The main cause of deforestation is agriculture (poorly planned infrastructure is emerging as a big threat too) and the main cause of forest degradation is illegal logging. In 2019, the tropics lost close to 30 soccer fields’ worth of trees every single minute.

Detailed explanation-4: -Selective logging-as usually practiced-degrades forest because the felling of a single large tree can bring down dozens of surrounding trees which are linked to the target tree by vines and lianas.

Detailed explanation-5: -Areas that have been selectively logged are much more likely to be settled and cleared by shifting cultivators than untouched rainforests because of road access. Logging gives access to rainforests, where fuel wood, game and building materials are available.
