Man-Made Pressures Have Attributed to Decline in Population of Pollinating Insects
Scientists have said that human actions have resulted to reduce the population of honeybees, bumblebees, and other insect pollinators. Mostly man-made pressures are responsible for the decline in population of the world's pollinating insects.
Intensive farming, climate change, spread of alien species and diseases are the major factors to attribute to the continued global decline.
The situations have become so serious that the scientists are worrying about the ability to supply adequate nutrients and dietary diversity to the world's growing population. The pollinators are very essential for many fruit, vegetable, seed, nut, and oil crops around the world.
Honeybees, bumblebees and other pollinating insects help them pollinate. But, since 1961, the number of crops grown around the world has grown so much that requirement for pollination has gone up three times.
According to experts, yields of three-quarters of crops are improved by the pollinating insects. Moreover, up to 94% of wild flowering plants rely on pollinating insects for reproduction.
"There is no single smoking gun behind pollinator declines. Pollinators face many threats and it's likely that these combine to exacerbate the negative impacts of each", says Dr. Adam Vanbergen from NERC's Centre for Ecology & Hydrology, lead author of the report.
