What are the 5 factors that affect 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.

What are the 6 factors that affect biodiversity?

The present review discusses the principal factors responsible for the loss of biodiversity such as pollution, habitat loss, hunting, introduction of invasive species, overexploitation of preferred species, climate change and natural disasters.

What are the major factors causes affecting biodiversity today?





Why is biodiversity important?

  • Changes in land use (e.g. deforestation, intensive mono-culture, urbanisation)
  • Direct exploitation such as hunting and over-fishing.
  • Climate change.
  • Pollution.
  • Invasive alien species.

What are the 4 major threats to biodiversity?

The human population requires resources to survive and grow, and many of those resources are being removed unsustainably from the environment. The five main threats to biodiversity are habitat loss, pollution, overexploitation, invasive species, and climate change.

How does biodiversity affect the environment?

Biodiversity also provides ecosystem services or benefits to people. These benefits include: hurricane storm surge protection, carbon sequestration, water filtration, fossil fuel generation, oxygen production and recreational opportunities.

What is the greatest factor is biodiversity?

Solution. 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.



How does population affect biodiversity?

Population growth and increasing resource consumption affect biodiversity in two ways: they create pressure to convert wildlife habitat into agricultural and urban land, and they produce wastes that pollute habitat and poison wildlife.

What biotic factors affect biodiversity?

Biotic Factors:



Biotic factors including things like predation, competition, and other species-level interactions that lead to increases or decreases of biodiversity. For example, the loss of a primary producer can drastically change the biodiversity within an ecosystem.

What are the biggest threat to biodiversity?

According to the UN’s Convention on Biological Diversity there are five main threats to biodiversity. In descending order these are: changes in land and sea use; direct exploitation of natural resources; climate change; pollution and invasive species.

What is harming biodiversity?

The main direct cause of biodiversity loss is land use change (primarily for large-scale food production) which drives an estimated 30% of biodiversity decline globally. Second is overexploitation (overfishing, overhunting and overharvesting) for things like food, medicines and timber which drives around 20%.

How pollution affects the biodiversity?

Air pollution may impact biodiversity if it: (1) alters genetic diversity within populations; (2) reduces the reproductive potential of biota; (3) reduces crop or natural vegetation production; and (4) impairs the structure and function of ecosystems. Air pollution effects on biodiversity are difficult to document.
