Read the given passage and answer the question carefully - 

The Amazon Rainforest, also known as the Amazon Jungle, spans eight countries and covers approximately 5.5 million square kilometers, making it the largest rainforest on the planet. The forest is known for its extraordinary biodiversity; it houses an estimated 400 billion individual trees representing 16,000 species.

A significant contribution to the Amazon's diversity is its intricate river system, with the Amazon River being the most voluminous river in the world. The river is roughly 6,400 km long, and its tributaries form a network of channels that interweave across the forest. This system creates habitats for aquatic organisms and serves as a water and food source for a multitude of terrestrial species.

The indigenous communities of the Amazon play a crucial role in its preservation. These groups, estimated to number approximately 400,000 individuals from over 350 distinct tribes, have lived symbiotically with the rainforest for thousands of years. They are crucial custodians of the forest, employing traditional practices to manage and protect it.

Deforestation poses a major threat to the Amazon Rainforest. This is largely driven by logging, agriculture, mining, and infrastructure development. The loss of the Amazon Rainforest can lead to significant biodiversity loss and contribute to global climate change due to the forest's role as a major carbon sink.
