What are the factors that affect biodiversity in India?
The biodiversity of any place is affected by the following factors such as the climate change and the deforestation and the overgrazing and invasion of species and also is affected by the levels of the pollution the rates of the poaching of the wildlife species and thus these factor are related to the destruction of …
What are the 3 factors that keep biodiversity in balance?
Three successful approaches to protecting biodiversity are captive breeding, laws and treaties, and habitat preservation. The number of different species in an area. A species on which other species in an ecosystem largely depend, such that if it were removed the ecosystem would change drastically.
What are the 4 factors that affect biodiversity?
Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
Why is it so important to protect biodiversity?
Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations.
What are the causes and effects of loss of biodiversity?
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 effects of loss of 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. For humans that is worrying.
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 are the five threats to 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.
How do humans affect biodiversity?
The main threats facing biodiversity globally are: destruction, degradation and fragmentation of habitats. reduction of individual survival and reproductive rates through exploitation, pollution and introduction of alien species.
How do humans benefit from biodiversity?
Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.
What are the three components of biodiversity?
Three components of biodiversity are ecosystem, species and genetic diversity.
What are some 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 is biodiversity and why is it important to an ecosystem?
Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.
What are the major threats to biodiversity?
Threats to Biodiversity
- Habitat Fragmentation. Ecosystem conversion and ecosystem degradation contribute to habitat fragmentation.
- Exotic Species Introductions. Infestation by alien species, such as the Codling Moth, is also a major threat to BC ecosystems.
- Pollution.
- Global Climate Change.
- Corridors and Connectivity.
How does biodiversity contribute to the economy?
Biodiversity Underpins Economic Activity Food production relies on biodiversity for a variety of food plants, pollination, pest control, nutrient provision, genetic diversity, and disease prevention and control. Both medicinal plants and manufactured pharmaceuticals rely on biodiversity.
