The last traveling pigeon on earth was shot by a little boy. If he knew it was the last one on earth, would he still kill it? The result is unknown, but the fact is that pigeons are indeed extinct and will never be seen again in life. Because of human selfishness and greed. I think so many animals are extinct because of us, so we should reflect.
The extinction of the traveling pigeon shows us that no matter how big the species was at that time, it still couldn't stand a lot of killing, just like the marsupial wolf in Australia, and it was also because humans killed it too frequently that it became extinct. There are countless such examples, and so many lovely lives have disappeared. In addition to regret, I hope that reason can overcome sensibility, and don't ignore ecological value and life value because of economic value.
