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 are 3 causes of biodiversity?
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.

Which type of biodiversity is most important?
Species diversity
It is the biodiversity at the most basic level. It includes all the species ranging from plants to different microorganisms. No two individuals of the same species are exactly similar. For example, humans show a lot of diversity among themselves.
What are the 3 types of biodiversity and why are they important?
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.

pollution, habitat loss, hunting
, introduction of invasive species, overexploitation of preferred species, climate change, and natural disasters.
What are the 5 factors that affect biodiversity?
Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention:
invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation

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.

- Ecosystem Diversity. …
- Functional Diversity.
What is biodiversity Why is it important for human life?
Biodiversity plays a crucial role in human nutrition
through its influence on world food production
, as it ensures the sustainable productivity of soils and provides the genetic resources for all crops, livestock, and marine species harvested for food.
What happens if we lose biodiversity?
The loss of biodiversity has two significant impacts on human health and
the spread of disease
. First, it increases the number of disease-carrying animals in local populations. … At the same time, habitat fragmentation brings humans in closer and more frequent contact with these disease-carrying species.
