Spraying toxic chemicals in nature is, not surprisingly, toxic
People tell anecdotes of how there used to be more squashed bugs on the windscreen of their cars – and they are right. Scientists believe that insect numbers have declined by almost 25% since 1990. This matters because insects pollinate our plants, clean our water, provide a food source for other animals and are vital to the decomposition of nature’s waste.
One of the main culprits are insecticides. The waving fields of modern agriculture are like a green desert devoid of life. Although we have reduced the quantity of pesticides used, we have countered it with an increase in the chemicals’ toxicity. Modern pesticides also persist in the field for longer and farmers are increasingly spraying prophylactically before pests may, may not, become a problem.
Insecticides are not only toxic to insects. As they seep into the soil and water, they become part of the food chains for fish, birds and other animals – including humans.
