1Amazon Rainforest

Amazon Rainforest: The Amazon is often referred to as the "lungs of the planet" due to its immense capacity for carbon dioxide absorption and oxygen production. This tropical rainforest spans across nine countries in South America and contains an unparalleled diversity of species .

2Great Barrier Reef

Great Barrier Reef: Located off the coast of Australia, this is the largest coral reef system in the world and one of the most complex natural ecosystems on the planet. It supports a wide variety of marine life and is crucial for the health of the oceans .

8Atacama Desert

Atacama Desert: This desert in Chile is considered the driest non-polar place on Earth, yet it still sustains life through unique adaptations. It's also an important site for astrobiological research due to its Mars-like conditions .

9Coral Triangle

Coral Triangle: Encompassing parts of Indonesia, Malaysia, the Philippines, Papua New Guinea, East Timor, and the Solomon Islands, the Coral Triangle is known for having the highest diversity of marine life in the world, including over 600 species of corals .
