This is the message from a leading biologist following a new scientific review of insect numbers, which suggests there will be "dramatic rates of decline" for 40 per cent of species around this world.
Meanwhile, the planet is said to be undergoing its sixth mass extinction due to the "biological annihilation" of wildlife in recent decades, while the insect population collapses that have already been reported in Germany and Puerto Rico are now thought to be related to a crisis that's global.
Currently, 40% of Earth's insects are at risk of dying out while another third are considered endangered, according to CNN. The wide use of pesticides and fertilizer as well as industrial pollution are also taking massive tolls.
"The conclusion is clear: unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades", they concluded. Lepidoptera, the order of insects that includes butterflies, which are often the canary in the coalmine for ecosystem problems, have declined by 53 percent.
Various insects are also a common food source for larger animals. 'It's quite plausible that we might end up with plagues of small numbers of pest insects, but we will lose all the wonderful ones that we want.' Prod Goulson added if huge numbers of insects disappear, they will be replaced - just don't expect it to happen anytime soon.
"The essential role that insects play as food items of many vertebrates is often forgotten", the researchers said.
