Chinanews, Beijing, November 27 ¨C According to a research by Zhang Zhigang, an environmentalist from Liaoning Province, from April to October every year, about 466 million insects are killed by crashing into cars on the highways in Liaoning, and Zhang estimates that the national figure can be as high as 160 billion.

¡°When we talk about highways, most of my fellow environmentalists only pay attention to car-emission, noise and the construction projects¡¯ impacts upon the environment, but the insects living near the highways are neglected,¡± said Zhang.

A car running at 60 km per hour is fast enough to kill all the insects that crash into them, added Zhang.
