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
