Biodiversity in Ecosystems
• Biodiversity: Variety of different species in an ecosystem.
• Rainforests have the highest biodiversity.
• Does our classroom have a high biodiversity?
• The International Union for Conservation of Nature (IUCN) notes in a video that many species are threatened with extinction. In addition,
• At threat of extinction are
• 1 out of 8 birds
• 1 out of 4 mammals
• 1 out of 4 conifers
• 1 out of 3 amphibians
• 6 out of 7 marine turtles
• 75% of genetic diversity of agricultural crops has been lost
• 75% of the world’s fisheries are fully or over exploited
• Up to 70% of the world’s known species risk extinction if the global temperatures rise by more than 3.5°C
• 1/3rd of reef-building corals around the world are threatened with extinction
• Over 350 million people suffer from severe water scarcity
