What is a possible consequence of decreased 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.

How would an ecosystem be affected by a decrease or increase in biodiversity and why?

Increasing species diversity can influence ecosystem functions — such as productivity — by increasing the likelihood that species will use complementary resources and can also increase the likelihood that a particularly productive or efficient species is present in the community.

What factors can cause loss of biodiversity in an ecosystem?

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 consequences of biodiversity?

Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

What are the disadvantages of low biodiversity?

Biodiversity loss affects economic systems and human society. … This lack of biodiversity among crops threatens food security, because varieties may be vulnerable to disease and pests, invasive species, and climate change.

How does biodiversity loss affect climate change?

The destruction of forests and other ecosystems undermines nature’s ability to regulate greenhouse gases in the atmosphere and protect against extreme weather impacts – accelerating climate change and increasing vulnerability to it, a report by the U.N. agencies on climate change and biodiversity said.

What is biodiversity explain major causes and consequences of degeneration of biodiversity?

Some of the causes and consequences of degeneration of Bio-Diversity are as follows: Bio-diversity means existence of various types of species of animals, vegetation and microorganisms in a habitat.

What are some causes for the loss of biodiversity Brainly?


  • Climate change.
  • Pollution.
  • Destruction of habitats.
  • Invasive alien species.
  • Overexploitation of the natural environment.
  • Extinction of species.
  • Threat to human beings.
  • Proliferation of pests.

What is decline in biodiversity?

Available evidence suggests there is a continuing decline in biodiversity. Species extinctions, secondary salinisation, soil decline, pest outbreaks, and declining native vegetation and water quality and quantity are among a range of symptoms of ecosystems losing the capacity to repair themselves.

What are the causes and consequences of biodiversity?

The various factors that influence biodiversity include -temperature, altitude, precipitation, soils, and their relation with other species. For instance, ocean biodiversity is 25 times lesser than terrestrial diversity. Biodiversity also increases its form as it moves from the poles towards the tropics.
