Last week I noticed a report saying biologists have discovered an enormous decrease in the amount of insects around over the last 25 years. They set up catches and caught insects over a certain time at the same places all over Europe. At the end of the catching period they weight the catch. Over the last 25 years they discovered, the catch shrink every year. Compared to the catch 25 years ago, they caught only 1/4 of the amount they caught 25 year ago. That’s a descent of 75%.
I believe this. When recalling the memories to my childhood, I remember very dirty front-screens of the cars after each longer trip in the countryside. Thousands of insect were smashed and have had to be removed. And nowadays? I’m still living in the same area, but I have to clean my front-screen only 2 or 3 time over the whole summer.
What does this mean? First of all, less food for the birds and other insectivores. But, it also means, there are less insects for pollination our food-plants. Over the next years we have to find a solution to bring back insects. This would also have an effect to the insectivores, especially the birds.
Don’t forget, not only the insects die. The vanishing of the local insects gives room for insects from other areas that don’t have enemies here but could endanger our health (think i.e. of the tiger mosquito bringing different kinds of dangerous illnesses).
So, don’t spray insecticides over your plants. Try to find natural ways to keep the unwanted insects away from your house and your garden. Give insectivores a home in your garden or near your house. Try to buy your food from farmers which avoid the usage of spraying insecticides (this is also a benefit for your own health because there is less poison to remove before you eat the food!)
