Content: One of the most apparent reasons for the decline in insect population is the use of pesticides. The loss of habitat can also endanger the existence of a species. Furthermore, habitat degradation and the decline and disappearance of plants and animals that insects depend on for food and shelter. Moreover, water pollution also has devastating effects on the environment and contributes to the problem of insect extinction. 6. America’s agriculture is 48 times more toxic to insects than 25 years ago. (PLOS One, National Geographic)
The agricultural landscape is toxic because of the widespread use of neonicotinoid pesticides, which can remain toxic in the environment for up to 1,000 days. The pesticides are responsible for 92% of increased toxicity. This is because plants absorb these chemicals into all of their tissues — stems, leaves, pollen, nectar, and sap. According to the study on insect population decline that was conducted in 2019, these chemicals are incredibly toxic to pollinators like bees and butterflies, while birds aren’t spared either.
