Since humans learned how to wrest food from the soil, bugs like corn earworm, the bean fly, and the grain weevil all have dined on the agricultural bounty. The insect pests across the globe consume more than 20% of the plants and vegetation that humans grow every year, and that total will keep increasing as the global warming is making these insects hungrier than before, as stated by a study that was published recently in the journal Science. This study can make the farmers use more of the pesticides on the crop, and that would cause environmental harm in the future, as stated by the scientists.
When the temperature increases in the environment by two degrees every time, the amount of wheat, corn, rice, and grain lost to the insects’ will increase by 10 to 25%, as stated by the study. The temperate agricultural regions such as that of the United States and Western Europe are going to be hit prominently. The international Paris agreement is designed in such a way that it keeps warning below two degree Celsius, but the world’s countries are more or less of the track meet the aim.
When the bugs are eating large amounts of crops in the field, the insects have consumed something like one out of every eight loaves of bread before it even gets made, as stated by Curtis Deutsch who is a professor of chemical oceanography at the University of Washington and also an author of the study. He also stated that if the environment gets warmed by four degrees, which is what when the climate models typically predict for the end of this century, then that amounts to insects eating two of the eight loaves of bread instead of one.
The higher temperature keeps increasing many of the insects’ metabolisms, and this makes them eat more. The lifecycle of these bugs also keep increasing, and this causes them to reproduce more quickly. Both the effects would destroy the crop yields even when the human population continues to increase that put additional strains on the worldwide food supply, as stated by the study. This is the reason why it has been stated that bugs are the ones that are going to eat away more than 30% of the human food by the next ten years and this might become a problem for humans.
