Meaning

The definition of biodiversity encompasses the degree of variations in organisms and/ or species within an ecosystem. The loss of biodeversity would be the diminishing of dfferent species within that ecosystem. For example, a lake may be the home to many types of fish. A change in the lake's temperature or chemistry may affect a food source for a certain type of fish. This type of fish may die out and leave the lake with one less species in it. The loss of one fish or food source may impact other populations and furthe diminish species diversity.

Cause

Invasive Species - plants or animals which have moved to a habitat where they were not naturally found and are more successful than local species. Habitat loss - Agriculture, housing and industry are destroying the habitats of many plants, animals and microbes. Our development means we must destory or decrease the natural ecosystems. Many animals have a certain range that they must maintain in order to live. If they do not have access to this area, their lives are significantly altered. Pollution - Our oceans, rivers, lakes and lands have become rubbish bins for society's industrial and organic waste. Plastic in our garbage causes enormous problems. It kills or injures many marine animals and birds either through accidental entanglement or ingestion of the material in the mistaken belief that the plastic is food. For example, sometimes bags are misidentified as jellyfish. Climate Change - Many plant and animal species are unlikely to survive climate change. For some species there will no longer be anywhere to live. Exploitation - We have drastically reduced some fish populations, hunted some whales to the verge of extinction and destroyed whole forests and their ecosystems. Blast fishing is another practise which reduces the coral reefs in the sea. It is practiced in many areas. This is the process whereby dynamite is placed into an area in order to catch a large quantity of fish. Coral reefs...
