Biodiversity and Human Impact Assessment

Latin America hosts more species than Africa and Asia combined, with biodiversity evolving over 100 million years. Human activities have significantly impacted ecosystems, leading to habitat fragmentation and species extinction. Conservation efforts are crucial to protect remaining biodiversity, with the UN declaring 2021-2030 as the Decade of Ecosystem Restoration.
