Scientists have identified top causes of pollinator death, including habitat destruction

An international group of experts led by the University of Cambridge identified the main causes of the extinction of all pollinator species.

Bees, butterflies, wasps, beetles, bats, flies and hummingbirds that spread pollen are all vital for the multiplication of over 75% of food crops and flowering plants.

A major 2016 report says that pollinator-dependent food production has increased 300% over the past half century, and the annual market value could be as high as $ 577 billion.

Dr. Lynn Dix of the Cambridge Department of Zoology put together a team of 20 scientists and indigenous people to try to conduct an initial assessment of the factors and risks of declining pollinators around the world.

According to the study, there are three main reasons for the mass extinction of pollinators:

  • destruction of habitat,
  • use of pesticides,
  • the impact of climate change.

For humans, the greatest direct risk is probably a lack of crop pollination. Scientists assessed this factor as serious.

Also, a decrease in the number of pollinators will affect wild plants. The inhabitants of Africa, the Asia-Pacific region and Latin America are most susceptible to this: it is there that people are most dependent on wild-growing food.

The biggest threat, according to the study, is Latin America – its inhabitants are most dependent on efficient cultivation of cashews, soybeans, coffee and cocoa. In addition, many pollinators such as hummingbirds live here.

China and India are also increasingly dependent on the export of fruit and vegetable crops that require pollinators.
