Nature dies slowly because of the noise of visitors

According to a recent study by US scientists, the noise pollution of visitors at some parks is destroying the natural environment, and threatening the environment.

More and more tourists like to go to the wilderness to see the scenery and seek tranquility. The sound of the wind blowing through the high trees, birds singing, murmuring streams, and the natural green color make visitors relax and escape from the modern life, big cities with many skyscrapers.

Deep forests, high mountains, narrow canyons and many other unspoiled areas are no longer peaceful, still as they are. Mixed in the natural sounds of the mountains and forests are the noise of tourists, music, honking .

According to a recent study by US scientists, the noise pollution of tourists in some parks is destroying the natural environment and threatening the habitat of wildlife species , in which There are endangered species.

Researchers have recorded about 1.5 million hours of noise over the past decade at 492 points, and compared between natural and human noise.

They found that about 63% of the sites had man-made noise twice as high as natural sounds. And in 21% of locations, artificial noise has increased by at least 10 times the sound of mountains.

Rachel Buxton, an Colorado State ecologist, said: "Although you are standing in the middle of a wild mountain, you still cannot escape the human-made sounds. There are really no boundaries. ".

The findings also indicate that noise pollution reduces 50-90% of the natural sound that you can hear. For example, in some areas, you can hear birds singing within about 30 m, but can only hear from 3-15m away.

In an effort to reduce noise pollution, federal officials at the Forest Department and the US Land Administration are considering building sound walls around industrial parks, as well as using public transport. Plus to shuttle visitors, to cut the flow of private vehicles into the park. They are also considering designing new road surfaces to absorb engine and tire noise, limiting large roads through untouched areas.

However, noise pollution not only negatively affects wildlife in these parks, but also people. Recent studies have shown that immersing in natural sounds makes you relax and improve your memory.

Natural sound is an important part of an ecosystem, as well as with human health and recovery. But noise pollution is affecting nature. "We need to understand the importance of natural sound, to protect them and to reduce the noise we make ourselves , " said George Wittemyer, Colorado State University biologist.
