The continent that has the largest rainforest is South America, which is home to the Amazon Rainforest. This vast tropical rainforest spans over 5.5 million square kilometers and is renowned for its remarkable biodiversity. The Amazon plays a crucial role in regulating the Earth's climate, maintaining atmospheric conditions, and serving as a carbon sink, absorbing vast amounts of CO2. The region houses countless species of plants, animals, and indigenous peoples. Deforestation and climate change pose significant threats to this vital ecosystem, highlighting the need for conservation efforts to protect the Amazon and its global significance.
