This is not a curious film. Different from the scientific and educational documentaries like "Animal World", although "Blue Planet 2" is also full of freshness, it gives people more reflection.
With such a vast area of ocean, the importance of the earth to human beings is self-evident. The impact of human activities on the oceans is still so huge that two hundred or even one hundred years ago, the oceans were still minimally affected by humans. In just one hundred years, the huge changes in the ocean obviously cannot be explained by normal natural changes. We always use natural changes to explain what happened in this century, such as the extinction of species, the melting of glaciers, and the increase in extreme climates, but this is likely to be self-deceiving, why in the decades of rapid development of human industry , has such a dramatic change? Some people say that there was a Little Ice Age in the Ming and Qing Dynasties, and now we have entered a thaw period, but can we still withstand this severe climate change? In today's globalization and population explosion, changes brought about by drastic climate change, such as crop yield reductions, storms, and related epidemics and blights, can all lead to violent turmoil. In addition to climate change, the unnatural decline of species and the series of ecological disasters associated with it have also overwhelmed today's fragile human societies. Therefore, regardless of whether climate change is related to human beings, climate and biota changes have already had a huge impact on human beings. Now it is time to pay attention and change, otherwise it will be worse in the past 50 years.
Seafood has become an important source of our food, a considerable part of which is wild. What we eat may be connected to whales thousands of miles away, and everything is connected. From this point of view, it is not impossible for us to do anything. Eating as little wild products as possible can reduce the compliance of the ocean, because the efficiency of artificial farming is much faster than that of nature itself. If we ask for more, the burden on the ocean will be heavier. No killing without buying and selling is not empty talk.
