Pesticide
A pesticide is a chemical or biological agent used to kill, repel, or control pests such as insects, weeds, fungi, or rodents that damage crops, spread disease, or invade homes. In today's world, it's a crucial tool for boosting agricultural yields and protecting public health, but its overuse has sparked debates over long-term effects on ecosystems and wildlife.
Did you know?
The widespread use of the pesticide DDT in the mid-20th century helped eradicate malaria in many regions, saving millions of lives, but its environmental persistence led to bioaccumulation in wildlife, famously causing eggshell thinning in bald eagles and nearly wiping out several bird species. This unintended consequence inspired Rachel Carson's 1962 book 'Silent Spring,' which played a pivotal role in banning DDT and launching the global environmental movement.
