Important direct drivers affecting biodiversity are habitat change, climate change, invasive species, overexploitation, and pollution (CF4, C3, C4. 3, S7).
What are the major factors affecting biodiversity today?
Major threats to biodiversity are:
- Habitat destruction/Deforestation.
- Introduced and invasive species.
- Genetic pollution.
- Over exploitation.
- Climate change.
- Human over-population.
What affects 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.
What are the five ways biodiversity is affected?
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 5 major effects of biodiversity loss?
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 the major problems that the Western Ghats is facing and why it is in the news?
The ecosystem in India’s Western Ghats is severely threatened due to the increasing human settlements, mining, pollution and the drop in genetic diversity. The Western Ghats of India is facing severe threats to its ecosystem. In the period between 1920 to 1990, 40 percent of its natural vegetation was depleted.
What are the 6 threats to biodiversity?
Below, we discuss six of the major threats to biodiversity: climate change, habitat loss and degradation, pollution, invasive species, over-exploitation and epidemics.
What factors affect biodiversity Why do wetlands have a high level of biodiversity?
Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.
What are the factors to increase biodiversity?
As a general rule, increasing biodiversity can be achieved by diversifying the range of habitats or vegetation structures available at a site. This can be achieved by, for example, varying mowing regimes, planting or seeding with native tree and shrub species, or occasional soil disturbance.
What are the causes of biodiversity?

Which of the following can be threats to the biodiversity of a geographical area?
Global Warming, fragmentation of habitat and invasion of alien species can be threats to the biodiversity of a geographical area.
What are the major factors affecting biodiversity today which one has the greatest overall effect How is climate change different from the other factors?
Climate change, deforestation and loss of habitat and pollution are one of the factors affecting biological diversity. The greatest factor would be climate change wherein animals and other species fail to adapt in changing climate thus resulting to their death.
What are 6 causes of habitat destruction?
The main causes of habitat degradation is pollution, invasive species, agricultural development, diminished resources, such as water and food, urban sprawl, logging, mining, destructive fishing practices and the disruption of ecosystem processes, such as altering the intensity and frequency of fires in an ecosystem.
How does lack of biodiversity affect an ecosystem?
Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
How does biodiversity affect 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. … Healthy ecosystems can better withstand and recover from a variety of disasters.
What are the main causes for the loss of biodiversity?
CAUSES OF BIODIVERSITY LOSS
- Climate change.
- Destruction of habitats.
- Invasive alien species.
- Overexploitation of the natural environment.
- Extinction of species.
- Threat to human beings.
- Proliferation of pests.
