Insect population is down by 45% in just 35 years

The world’s population of creepy crawlies has fallen by nearly half – but that is bad news for us, experts warn. A study published in the journal Science, reveals that the number of slugs, spiders, worms and other invertebrates has fallen by 45 per cent over the past 35 years as the human population has doubled. Experts fear this will harm the planet as creepy crawlies play an important role in pollinating crops, pest control, decomposition and ensuring soil remains packed with nutrients, as well as water filtration. In the UK the number of beetles, butterflies, bees and wasps has fallen by up to 60 per cent. Experts warn that fewer insects would have a huge effect on crop production as up to 75 per are pollinated by insects, amounting to around 10 per cent of the world's food supply. And the cost of pest control without natural predators could be more than £2.6 billion pounds in the United States alone. Scientists fear a drop in the insect population could also spark a decline in birds, which prey on pests that damage crops, and amphibians, which help keep water supplies free from algae. Decreasing invertebrate numbers are also known to compromise food production due to reduced pollination, seed dispersal and insect predation.
