First: protect the environment, starting with me.
In fact, the extinction of paddlefish has a lot to do with environmental pollution. Because human littering has seriously polluted the ecological environment of the Yangtze River, there are fewer and fewer habitats and less food that the paddlefish can eat. This made the number of white sturgeon less and less, and finally became extinct. Therefore, human beings should pay special attention to the environment. Everyone should start from himself. Don't litter, use less plastic bags, and don't overfish in the Yangtze River.
Second: cultivate environmental awareness from an early age.
In fact, environmental protection has been publicized, but it has not really been accepted in people's minds. But in contrast, some foreign countries and Taiwan Province Province have been doing environmental protection since childhood, so this awareness is deeply rooted, and they will consciously do something about environmental protection. For example, sorting garbage, picking up garbage at will, saving water and using cloth bags. These things seem to have nothing to do with protecting animals, but they are actually very beneficial to changing the ecological environment. If everyone can restrain themselves and be strict with themselves, then the environment for human survival will not become like this.
Third, establish a rare animal protection base.
When the number of rare animals decreases, it means that their living environment has become very bad, so human intervention is needed. The protection base established by humans is definitely the most suitable for these animals to survive, and humans will provide the most suitable conditions, whether it is food or accommodation environment. Moreover, human beings can also help these rare animals to reproduce artificially, which is also the most effective way to help these rare animals reproduce quickly and increase the number of animals.
Although this way may make these animals lose their ability to survive in the wild, it is most important to at least let this species survive. As long as the number of these animals can be stabilized, there is no need to worry so much.
