Two years ago I asked the question in the title of this piece. Now comes a wide-ranging study that suggests we are about to test that question in a major way.
The study predicts that at the current rate of loss of insect species, 40 percent could be gone "in the next few decades." What is particularly alarming is that this "could trigger wide-ranging cascading effects within several of the world's ecosystems." That means that many other life-forms including other animals and plants could find themselves without what they need to survive in this dangerous game of musical chairs orchestrated by humans. Might we be one of those species?
Insects do much of the crop pollination necessary for food production. A list of crops pollinated by bees is quite long. Humans could survive without these foods, but the nutrition and variety in our diets would be severely limited. And yet there is a greater problem. Outside of agriculture 80 to 95 percent of plant species require animal pollination. Since those plants are the base of every food chain, catastrophic declines in insect populations could lead to a collapse of existing ecosystems. The exact scope and effects of such a collapse cannot be fully anticipated. But it is doubtful humans would be unharmed.
