I just finished watching "Blue Planet II Our Blue Planet" for the second time. I feel that I have some thoughts and I want to express it.
This episode showcases human protection of killer whales and herring, the impact of human-made sounds on marine life, the harm of human-made garbage to other animals, human protection of leatherback turtles, exploration of whale shark spawning grounds, human protection of sperm whales benefits, coral reef death.
It can be seen that many of the manifestations are caused by humans. For example, we overfished herring. When the herring was about to become extinct, humans began to protect it again, and the number of herring has rebounded.
The sound made by humans interferes with the communication of fish and makes many fish easily eaten. However, if humans can mute the sound, or specify when to make the sound, it will reduce the disturbance to the inhabitants of the ocean.
Humans have created a lot of garbage and it has flowed into the ocean. Albatrosses ate the garbage and spit it out. Only then did people realize how many animals were killed by the garbage we made, even the cute little dolphins were killed... ...but if we can get all the garbage back and deal with it, they don't have to die.
Humans can also protect leatherback turtles, set up marine protected areas, reduce carbon dioxide emissions... and protect our blue planet together!
