Loss of Biodiversity
Biodiversity refers to the variety of life on Earth, including genetic, species, and ecosystem diversity. Loss of biodiversity is occurring at an alarming rate, with up to 20,000 species estimated to go extinct each year. Habitat destruction and fragmentation due to human activities like agriculture, construction, and urbanization are major drivers of biodiversity loss. Other threats include overexploitation of species, introduction of exotic species, pollution, climate change, and poaching. Widespread biodiversity decline poses serious risks to ecosystem balance, food security, natural disaster mitigation, and could ultimately threaten human survival if left unaddressed. Conservation efforts are needed to protect the estimated 24% of mammals and 12% of birds currently considered globally

Extinction causes and consequences .pptx
Polar bears are threatened by climate change-induced loss of summer sea ice. Their populations have declined, and they could be extinct in the wild by 2100. Current extinction rates are 100-1000 times higher than historical background rates, and are projected to increase to 10,000 times background rates by 2100 due to human activities. Protecting habitats, establishing protected areas, regulating trade and take of threatened species, and addressing climate change can help reduce extinction rates.

This document provides information about threats to biodiversity and causes of species extinction. It discusses how the passenger pigeon went extinct in the early 1900s due to overhunting. Current extinction rates are estimated to be 100-1000 times higher than background rates. The greatest threats to species are habitat loss, invasive species, human population growth, pollution, climate change, and overexploitation. Species become locally or globally extinct for various reasons, and preserving biodiversity is important for ecological, economic and ethical reasons.

Giant otter good
The document discusses the impacts of technology and science on giant otters, as well as threats facing the species. Technology has helped giant otter conservation through protected areas and zoos, but some are still illegally poached. Scientific research and equipment aid recovery efforts, while pollution, dams, and mining harm giant otter habitats and health. Though once numbering only 12, conservation efforts have increased giant otter populations to an estimated 2,000-5,000 in the wild. However, they remain the rarest otter and otter species loss of habitat and pollution pose major threats.
