We all love animals, but animals don’t feel the same way about us. When we enter their wild world, we are “unnatural” invaders into their homes.
There was a video many of you may have seen on the Internet recently of a bear and its cub (幼崽) climbing up a steep, snow-covered hill in Russia. The mama bear makes it to the top without too much trouble, but the baby bear keeps sliding back down. It takes three attempts to reach the top and, no doubt, many cheered at the cub’s never-give-up spirit. But nature scientists who saw the video didn’t cheer.
Instead, the scientists were upset that the two bears had been frightened into making a dangerous, unnecessary climb by the drone (无人机) that was filming them. Sophie Gilbert of the University of Idaho said, “It showed a complete lack of understanding from the drone operator of the effects his actions were having on the bears.” Other scientists have found that when a drone is hovering near, a bear’s heart rate can increase from 41 beats per minute to 162 beats per minute — a high enough rate to cause a heart attack.
Human disturbance has actually been having a far-reaching influence on wildlife. Researchers at the University of Berkeley recently found that many mammals are turning into “night owls” again to avoid contact with humans. Such a shift might not only affect those species themselves, but also have numerous chain effects.
We human beings find ourselves in a strange position in nature. We are part of it but also separate from it, now more than ever, since most of us live in cities. So, when we go off hiking into wild areas to “re-connect” with nature, we should go softly and considerately. It’s OK to get close to our animal friends, just not too close — we wouldn’t want to scare them, would we?
