The unique ecological area found in South America is the Amazon Rainforest, which is rich in biodiversity and home to an estimated 390 billion individual trees belonging to about 16,000 species. This vast tropical rainforest plays a crucial role in regulating the Earth's climate and is often referred to as the "lungs of the planet" due to its ability to produce significant amounts of oxygen. The Amazon fosters a myriad of wildlife, including countless species of birds, mammals, and insects, many of which are endemic and found nowhere else on Earth. Its health is vital for global ecological balance.
