Name four causes of the loss of biodiversity.

Habitat loss and fragmentation, which is by far the most important. Over-exploitation of species for food, medicine and trade. The introduction of alien invasive species that displace native ones. Co-extinctions, where the loss of one species takes its obligate associates with it.

No citable source has been recorded for this record. Treat it as practice material, not as fact.

Explanation

These four are often called the evil quartet.
