Classifications of Endangered species
All together there are nine categories and these are;
- Extinct (EX)
- Extinct in the wild (EW)
- Critically endangered (CR)
- Endangered (EN)
- Vulnerable (VU)
- Near threatened (NT)
- Last concern (LC)
- Date deficient (DD)
- Not evaluated (NE)
What is Biodiversity?
Biodiversity, short for biological diversity is the different species of animals and plants that inhabit a particular place. It is the term used to describe the variety of life found on Earth and all of the natural processes. There are different aspects of biodiversity which all have a strong influence on each other.
Island Biodiversity
If all abiotic factors are the same then the larger islands will have greater biodiversity. When a smaller island is in a warmer climate then a lager, the smaller island will probably have a greater biodiversity.
Importance of Biodiversity
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example if there were a larger group of plants species its means there would be a greater variety of crops. Biodiversity adds to the beauty of nature. Life depends on life: breaking any one part of a food chain can have devastating effects on a community. Biodiversity brings stability to an ecosystem. For example; if you have a cornfield and diseases as compared to a rain forest where the same species is spread out.
Threats to Biodiversity
There are a lot of different threats to global biodiversity these include over hunting, habitat destruction, climate change, species introduction and pollution. The average rate of extinction over the past 200 million years is 1-2 species every million years and 3-4 families. The average duration of a species is 2-10 million years (based on last 200 million years). When habitats are lost, the essentials of life are lost for species that depend on those habitats, for example; making a meadow into a parking lot, draining a swamp for housing developments and mining coral for building material and collecting for souvenirs and aquarium decorations. Habitat fragmentation separates wilderness areas from other wilderness areas. For example building roads and cities. Habitats can become virtual islands.
