The country known for its unique biodiversity and ecosystems is Brazil. It is home to the Amazon Rainforest, the largest tropical rainforest in the world, which hosts an incredible variety of plant and animal species, many of which are endemic, meaning they are found nowhere else on Earth. Brazil's diverse ecosystems range from rainforests to savannas, wetlands, and coastal regions, contributing to its status as a megadiverse country. Biodiversity in Brazil is critical for ecological balance and offers numerous resources for medicine, agriculture, and tourism. However, it faces challenges such as deforestation and habitat loss, threatening its rich natural heritage.
