Major causes of biodiversity loss and their direct consequences. Biodiversity is the richness of variety of life in an area. While there is still much that we do not know about life itself and this beautiful and mysterious world we live in, we do know that life on earth is interconnected.

Coral Bleaching: Coral bleaching occurs when the symbiosis between corals and their symbiotic zooxanthellae breaks down, resulting in the loss of the symbionts and a rapid whitening of the coral host (thus the term "bleaching"). This is a stress response by the coral host that can be caused by various factors, but more severe and frequent ...

Irreversible 'scars' are being produced through mining and quarrying for construction and engineering works, not to mention its effect on varied species of plants and animals. Organisms that find it difficult to survive in a changing environment die out, altering the ecosystem – ultimately leading to loss of biodiversity.

The main cause of damage and decreased quality of coral reefs is suspected to come primarily from inappropriate fishing methods, coral reef mining and sedimentation. Destructive fishing practices, such as the use of dynamite, the use of toxic cyanide, muro-ami fishing techniques and destructive fishing nets cause damage to coral reefs.

Coral reef collapse. Coral reefs are home to some of the planet's most biodiverse ecosystems. They are critical to ocean health: although they make up less than 1% of the ocean floor, 25% of fish species rely on reefs for at least part of their life cycle. 45 Ocean reefs contribute to the livelihoods of at least 500 million people worldwide, mostly in less-developed economies. 46 Coral …

The study is the first to document biotic homogenization on coral reefs. Previous studies have shown that the apparent richness of wildlife in any given ecological community can mask a loss of diversity among ecosystems as species are shuffled due to various pressures, including climate change; this is sometimes called a hidden biodiversity crisis.
