Environmental Impact and Carbon Cycle

Carbon is a key element in the universe and life, present in water, soil, and air as CO2. A balanced carbon cycle is crucial for a healthy ecosystem, but human activities have increased CO2 levels, disrupting this balance and affecting the climate. The Amazon plays a vital role in carbon sequestration, but deforestation and burning release more CO2. Efforts like USAID's programs aim to protect the Amazon and manage resources sustainably, ensuring global climate stability.
