Biodiversity loss is caused by five primary drivers:
habitat loss, invasive species, overexploitation (extreme hunting and fishing pressure), pollution, climate change associated with global warming
.

What are the causes and effects of biodiversity loss?
Habitat destruction is a major cause of biodiversity loss. Habitat loss is caused by
deforestation, overpopulation, pollution, and global warming
. Species that are physically large and those living in forests or oceans are more affected by habitat reduction.
What are the 7 major threats to biodiversity loss?

What happen if there is biodiversity loss?
Biodiversity loss can have
significant direct human health impacts
if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.
How can we prevent loss of biodiversity?
- Government legislation.
- Nature preserves.
- Reducing invasive species.
- Habitat restoration.
- Captive breeding and seed banks.
- Research.
- Reduce climate change.
- Purchase sustainable products.

What are the effects of biodiversity?
These ecological effects of biodiversity in turn are affected by both
climate change
through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations.
