What are drivers in biodiversity?
Following the MEA2, we considered five major drivers of biodiversity loss: climate change, habitat change, invasive species, overexploitation and pollution.
What are the main drivers of habitat loss?
The main causes of habitat degradation is pollution, invasive species, agricultural development, diminished resources, such as water and food, urban sprawl, logging, mining, destructive fishing practices and the disruption of ecosystem processes, such as altering the intensity and frequency of fires in an ecosystem.

What is importance biodiversity?
Biodiversity is important to humans for many reasons. … Ecological life support— biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services.
What is the importance of biodiversity explain the causes of loss of biodiversity class 12?
The loss of habitat will result in fragmentation of habitat leading to small habitat with few organisms. The main reason for decrease in biodiversity is overpopulation, global warming, deforestation, and pollution.
