Insect Armageddon



Insect Armageddon
There is alarming new evidence that insect populations worldwide are in rapid decline. As Prof. Dave Goulson of the University of Sussex, a co-author of a new insect study, put it, we are “on course for ecological Armageddon” because “if we lose the insects, then everything is going to collapse.”
This "ecological Armageddon" is apparently not due to climate change, though still due to human actions.

The study, which tracked flying insects collected in nature preserves across Germany, found that in just 25 years, the total biomass of these insects declined by an astonishing 76 percent. The reasons for the decline are not entirely clear — and only flying insects were collected, so the fate of crawling insects, for example, is not known — but the scientists suspect two main culprits: the use of pesticides and a lack of habitat in surrounding farmland.
While not more evidence for climate change, it nevertheless has important implications for what life will be like as global warming advances.  The loss of insect life will have a very unfortunate impact on our ability to grow our food.
The disappearance of creepy, crawly, buzzing insects doesn’t elicit the kind of emotional response that, say, global warming’s threat to polar bears does. Many may be quick to say, “Good riddance!” But we cannot survive in a world without insects, as they are critical for pollinating our food and are themselves a food source for many fish, birds and reptiles. Insects are also nature’s scavengers and soil aerators.
We are going to have to do something to halt the insect carnage.
There are proven steps that could be taken now to help stem this decline. Buffer zones of wildflowers and native plants around single-crop fields can help, as can agricultural practices that respect biodiversity and reduce or eliminate the use of pesticides and herbicides. Our planet’s rapidly disappearing forests, wetlands and grasslands need to be preserved and restored wherever possible. More research is also needed to better understand why, where and what insects are disappearing and how they can be saved. But one thing is already clear: The fate of the world’s insects is inseparable from our own.
