Why it is so important to protect terrestrial and aquatic biodiversity? What are the major threats
affecting terrestrial and aquatic ecosystems?
Answers
Answer:
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.
Answer:
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. ... Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.
Runoff from agricultural and urban areas hurts water quality. Draining of wetlands for development depletes habitats. Overexploitation and pollution threaten groundwater supplies. Invasion of exotic species can harm native animals and plants.
