What is habitat destruction?

Back

Habitat destruction refers to the process in which natural habitats are rendered unable to support the species present, leading to a decline in biodiversity. It is often caused by human activities such as deforestation, urban development, and agriculture.

What is the difference between provisioning and regulating ecosystem services?

Back

Provisioning services are the products obtained from ecosystems, such as food, fresh water, and raw materials. Regulating services are the benefits obtained from the regulation of ecosystem processes, such as climate regulation, water purification, and pollination.

What is overfishing?

Back

Overfishing is the practice of catching fish at a rate faster than they can reproduce, leading to a depletion of fish stocks and negatively impacting marine ecosystems.
