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. In each case, human beings and their activities play direct roles.
What are the 10 major causes of biodiversity loss?
- Cause #1 Destruction of Habitat:
- Cause #2 Hunting:
- Cause #3 Exploitation of Selected Species:
- Cause #4 Habitat Fragmentation:
- Cause #5 Collection for Zoo and Research:

- Cause #7 Pollution:
- Cause #8 Control of Pests and Predators:
What has caused the major decline in biodiversity?
Habitat loss is the primary cause of decline for species and populations because it removes the flora and fauna that each species requires for life. When more and more land use occurs within areas of high species richness, loss of biodiversity is greatly exacerbated and species extinctions increase.
What are the 5 major causes of biodiversity loss?
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 four causes of biodiversity loss?
- Climate change.
- Pollution.
- Destruction of habitats.
- Invasive alien species.
- Overexploitation of the natural environment.

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?
Human Activities and Loss of Habitat, 2. Deforestation , 3. Desertification, 4. Marine Environment, 5.
What is the biggest biodiversity loss?
Climate change was ranked as a 6% risk to Earth’s biodiversity. WWF’s Living Planet Report 2020 has ranked the biggest threats to Earth’s biodiversity. The list includes climate change, changes in land and sea use and pollution.
What is the biggest threat to the loss of biodiversity?
Habitat loss is the single greatest threat to biodiversity on Earth today and in fact it is the second largest threat to our existence on this planet next to Climate Change.
What are examples of biodiversity?
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers , and microscopic bacteria that can’t even be seen by the naked eye.
What are the 3 kinds of biodiversity?
Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversity . These three levels work together to create the complexity of life on Earth.
What is biodiversity in simple words?
Biodiversity is the shortened form of two words “biological” and “diversity” . It refers to all the variety of life that can be found on Earth (plants, animals, fungi and micro-organisms) as well as to the communities that they form and the habitats in which they live.
Why is biodiversity important 5 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. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
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.
