First of all, from the marine life itself, we humans should not kill again. It is precisely for this reason that our country has now listed many marine organisms as national protected organisms, and no one can fish them, or there is a fishing ban within the specified time. In this way, in order to prevent the extinction of marine life, we must ensure their reproduction, so that their number can be kept in a certain balance, so we like marine life at the same time, we should not be able to fish and kill them. Only when we protect it, the number of marine life will increase in the future, so that people and nature can live in harmony, which is what our country wants to see. This is the fundamental purpose of protecting nature in our country in recent years.
Secondly, judging from human actions, we should also protect the living environment of marine life to some extent. Now we are constantly exploiting resources and wasting resources, even littering, which has changed our living environment to some extent, but we humans have a solution, but for those marine creatures, they are helpless. Seeing that the environment on which they live has been changed step by step, they can only accept it, but they can't survive in such a polluted ocean, so many marine creatures have died, and we can see from many platforms that most of the marine creatures have garbage in their bodies now. If we humans don't stop polluting the environment, it will definitely cause serious consequences in the future. So we should care for marine life from the aspect of protecting the environment.
Finally, we should care about the reproduction of marine life. Now there are many creatures that are on the verge of extinction, so we should breed them and let them reproduce so as to keep this marine life from further reproduction, so as to make all kinds of creatures on our earth diverse. If something like the extinction of dinosaurs reappears for some reason, it is impossible to imagine how the earth will be silent after hundreds of years.
