Detailed explanation-1: -Large-scale deforestation of the Brazilian Amazon began in the 1960s, when government incentives to clear land for production coincided with more effective tools such as chainsaws and bulldozers.

Detailed explanation-2: -Brazil has lost 20% of its rainforest to deforestation, making the country one of world’s biggest contributors to greenhouse gases and global climate change.

Detailed explanation-3: -Cattle ranching is the leading cause of deforestation in the Amazon rainforest. In Brazil, this has been the case since at least the 1970s: government figures attributed 38 percent of deforestation from 1966-1975 to large-scale cattle ranching. Today the figure in Brazil is closer to 70 percent.

Detailed explanation-4: -Deforestation disrupts the natural water cycle provided by trees. The evaporated water vapor from trees forms clouds and provide rain to agricultural areas near there. When there are less trees, there is less rainfall, resulting in large environmental impacts due to drought.
