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.
What are 3 types 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 your own 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.
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 increases species diversity?
At regional scales, diversity is also increased by speciation and decreased by extinction. These decreases in diversity include those caused by regional extinction events that extirpate species from the region in question but not necessarily from all other regions.
What are the elements of biodiversity?
Three components of biodiversity are ecosystem, species and genetic diversity . Ecosystems perform functions that are essential to human existence such as oxygen and soil production and water purification.
What is the important of 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 biological diversity?
The term biodiversity (from “biological diversity”) refers to the variety of life on Earth at all its levels , from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that sustain life.
What is the main threat to biodiversity?
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. The WWF used data from over 4,000 different species.
What is the major cause of biodiversity loss?
The numerous factors are responsible for the loss of Biodiversity (Figure 1) such as 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 will happen if we lose biodiversity?
Biodiversity underpins the health of the planet and has a direct impact on all our lives. Put simply, reduced biodiversity means millions of people face a future where food supplies are more vulnerable to pests and disease , and where fresh water is in irregular or short supply.
