When nature meets man-made roads, it’s seldom a good thing. Millions of animals get killed by cars every week. So, engineers tried to build green bridges for animals over busy roads. These bridges help keep animals and people safe.
The idea of green bridges isn’t really new. In fact, the first animal crossing appeared in France in the 1950s. As well as Germany, which has made more than 80 green bridges since 2005, Canada and the United States are also trying to protect native wildlife by building animal bridges over the years.
Although there are various designs, most green bridges share something similar. First, they are usually quite wide, giving animals plenty of room to move. Second, they are usually covered with soil and plants to look like the forests that lie on either side of the roads. Lastly, they are wider at the ends, spreading out where they meet the land. This helps gather animals onto the bridge and guide them out when they leave.
People may wonder ________. In Canada’s Banff National Park, 11 kinds of large animals such as bears, elk and cougar s have already gone across these green bridges more than 200,000 times since 1996. In some places, we’ve also seen a 90% drop in accidents between animals and cars where these bridges have been built.
These crossings are clearly a step in the right way to offer living chances and safety to wild animals. And with these bridges, both animal and human deaths on roads will continue to go down.
