What is an example of biodiversity loss?

An example of biodiversity loss was the extinction of over 200 species of cichlids in Lake Victoria; this was caused by the introduction of the Nile Perch as well as increased agriculture and fishing. Unlike the five previous mass extinctions, the current one is a result of detrimental human activities.

What are the three main levels of biodiversity quizlet?

Biodiversity is the variation of life forms in a particular ecosystem. All levels of biodiversity are interconnected, but there are three levels at which biodiversity is broken down and studied: genetic diversity, species diversity and ecosystem diversity.

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

What are the cause of biodiversity and destruction?

Habitat destruction

Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by deforestation, overpopulation, pollution, and global warming. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.

Where is loss of biodiversity The worst?

A study by 16 global conservation organizations found that the biodiversity crisis is most acute in freshwater ecosystems, with a rate of decline double that of oceans and forests. Global populations of freshwater fish are collapsing from anthropogenic impacts such as pollution and overfishing.
