About Amazon Rainforest:
- Amazon rainforest is a moist broadleaf tropical rainforest, located in Amazon biome. It covers about 80% of the Amazon basin in South America.
- This region includes territories of nine nations. Majority of the forest (60%) is in Brazil. It is followed by Peru (13%) and Colombia (10%).
- Minor forests are in Bolivia, Guyana, Ecuador, Suriname, French Guiana, and Venezuela. Amazon represents more than half of Earth’s remaining rainforests.
- The Amazon’s rainforest is home to 30 per cent of the world’s species, comprising 40,000 plant species, 16,000 tree species, 1,300 birds and more than 430 species of mammals.
- They are very wet places, receiving more than 200 cm rainfall per year, either seasonally or throughout the year.
- Temperatures are uniformly high - between 20°C and 35°C.
Deforestation of Amazon:
- Main causes of deforestation in the Amazon are human settlement and development of the land. In 2018, 17% of the rainforest was already destroyed.
- Cattle Ranching:
- One of the leading causes of deforestation in the Amazon Rainforest is linked to beef consumption.
- Vast areas of forest are cleared by cutting down trees and burning the forest down in order to create pasture land for grazing cattle.
- Small-scale agriculture
- As with ranching, small-scale agriculture requires the forest to be “slashed and burned” to clear the ground for crops and grazing of various types.
- Forest fires
- Industrial Agriculture Operations
- Mining operations
