3 key details abt the TRF
Deforestation rate: Around 17% of the Amazon has been lost in the last 50 years, mainly due to logging, cattle farming, and road building. Biodiversity: Home to over 10% of all known species on Earth — one of the most biodiverse places in the world. Climate impact: It's a carbon sink, storing huge amounts of CO₂ — deforestation contributes to global warming.

3 ways to manage the rainforest sustainability
Selective Logging: Only cutting down older or less valuable trees instead of clear-cutting whole areas, allowing the forest to regenerate. Ecotourism: Tourism that respects the environment and supports local communities (e.g., guided rainforest tours with minimal impact). International Agreements: Programs like REDD+ (Reducing Emissions from Deforestation and Forest Degradation) pay countries to protect their rainforests.
