Some people think that our planet in the distant past has experienced a period of global warming, and more recently in the US city of Raleigh was able to find some kind of "message" from that distant era - the tiny deadly insects.
Entomologist Emily Meynike that found insects, believes that this global warming is to be repeated in the next 50 years. Her team found a beetle the size of a light blёstku called "scaly", and such insects in tropical areas proved 13 times more than in cold. They settle on the trees and eventually kill them. Of course, the bugs have been known to science before, but their number is growing rapidly.
For a man beetles are harmless, but they cause great damage to the environment. The main problem is that the bugs spoil the trees are an important cornerstone of urban ecosystems. Considering the fact that the urban environment and so not too favorable for the plants, with an increase in the number of bugs most of the trees will die. This will lead to even greater air pollution in urban areas, and hence reduce the number of healthy people. In addition, trees are home to birds and other vertebrates, and the loss of trees will lead to a reduction in their numbers.
Meynike and her colleagues suggest that, at least in the cities and more comfortable conditions for increasing the number of beetles, but soon they will appear in the woods. If the trees in the forests die, the animals living there will become more vulnerable, and all the factors together lead to irreparable violations in the natural food chain.
If you want to understand how the city of the future will look like, just imagine the bare tree trunks, covered with a carpet of insects stirring.
