Why is biodiversity bad for the environment?

This lack of biodiversity among crops threatens food security, because varieties may be vulnerable to disease and pests, invasive species, and climate change. Similar trends occur in livestock production, where high-producing breeds of cattle and poultry are favoured over lower-producing, wilder breeds.

Why do we need to protect biodiversity?

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.
