It happened on a rainy Saturday morning last month. My wife Catherine and I were driving along what some people called moose alley（麋鹿通道）. It was so early that there were few cars on the road. Suddenly, something happened. A moose jumped out across our path. I had been driving for years and was good at driving. In order to avoid knocking into the moose, I made a quick turn to the other lane. If I had not done that, the moose might have been killed, and my wife and I might have got injured，too. A few seconds later, when stopped and looked back in my rear view mirror, the moose was getting up and then ran into the bush. Shaken but fine, we both looked at each other with a surprised expression.
From then on, I often thought about the relationship between humans and wildlife. We know that animal species（物种） have appeared and disappeared continually since life began on the Earth. It is quite natural. However, animal species have been decreasing at a much faster rate for about a century now because of human factors (因素) such as pollution.
Certain philosophers and scientists keep repeating that if we don't save animals, how we will be able to save ourselves. A better knowledge of animals gives us a better understanding of our own species. The will to protect animals and nature in general shows the value of a society. And all animals play roles in nature and have a right to survive. Therefore, I think we should try our best to save endangered animals, because humans cannot live on the Earth alone.
