Biodiversity and Habitat Conservation

The lecture discusses biodiversity and conservation, focusing on the causes of biodiversity loss, known as the 'evil quartet': habitat loss, fragmentation, over-exploitation, and invasive species. It highlights the impact of habitat loss on tropical rainforests, particularly the Amazon, and the consequences for species extinction. The lecture also covers the effects of habitat fragmentation on animals with large territories and migratory habits, leading to their extinction.
