“A new report for the Wildlife Trusts has suggested half of all insects may have been lost since 1970 as a result of the destruction of nature and heavy use of pesticides.

The report said 40 percent of the one million known species of insect are facing extinction. It also found that 23 bee and wasp species have become extinct in the last century.” (Country life.co.uk)
