The Amazon Rainforest, often referred to as the “lungs of the planet,” is home to an astonishing 390 billion individual trees. This immense jungle spans over 5.5 million square kilometers (or 2.1 million square miles) across nine countries.

Despite covering just 1% of the Earth’s surface, it houses an estimated 10% of the known species. From the iconic jaguar to vibrant poison dart frogs, the Amazon’s biodiversity is as mystifying as it is crucial for global ecological balance.
