Through careful investigation and study, the author discusses some problems facing the earth, such as the sharp decline of some fish, the destruction of ozone layer, the depletion of fresh water resources, global warming, and the increasingly poor soil, which truly shows the realistic problems facing mankind and makes people think deeply. In addition, the author lists a large number of examples of personal opinions, actions and new ideas, such as saving energy, researching and developing new technologies, respecting the inherent way of nature, applying new lifestyles, etc. In this way, we can minimize the pollution and harm to the earth. Many ideas in the book can make the environment and management reach an agreement and continue to develop in a healthy direction.
Finally, the author clearly points out that the change must be thorough, and if the scale of remedial action does not match the scale of various crises, then we are doomed to failure.
Little Earth is short, but it covers a wide range. For example, when it comes to agriculture, the author starts with bionics, and then discusses the foundation of agriculture-soil, and the influence of modern industrialized agriculture on soil. Now the output has increased, but at the expense of quality. What's more, more fertilizers are applied and genetically modified foods are abused. The destruction of the earth by human "new technology" is remarkable. This book describes human "behavior" in detail, prompting people to rethink their living environment and lifestyle.
The ever-changing temperature makes it too late for all kinds of species on earth to adjust and adapt. If this happens, the whole ecosystem will collapse, and if farmers can't rely on the existing weather patterns, the whole food system will be threatened. If the ice sheet off the coast of West Antarctica leaves its original position, the sea level will rise by 6 meters, and the infrastructure of many cities and most developed countries will be submerged in a Wang Yang, including many nuclear reactors. All the above mentioned are true, not groundless predictions. Almost all the predictions have been proved wrong now, and the reality is completely different from the prediction. The mistake made by economists mentioned above is to regard prediction as an eternal truth. The actions we take should be based on the idea of keeping our behavior in harmony with the changing process of our only home on earth, and can never be based on prediction.
Past experience is not encouraging. Almost every week, newspapers publish reports about natural disasters, extreme weather changes or chaotic ecosystems. People are used to comparing corals to miners' canaries. Once the canary reveals his place of residence, the miner will know that he is in extreme danger. However, coral reefs around the world are slowly disappearing; The number of krill in antarctica is also greatly reduced; The early arrival of spring leads to the inconsistency between the peak demand for bird food and the number of insects that can be caught; Some tropical diseases, such as malaria, are spreading to other areas; The ice in the Arctic is thinning. 1998 The flood in the Yangtze River forced 56 million people to leave their homes, which is probably related to global warming. However, in Bangladesh, 26 million people were made homeless by floods. Hurricane Mitch also occurred in 1998, killing 18000 people. Other similar weather disasters occurred in Orissa, India and Mozambique. However, these examples mentioned above are only the result of the global temperature rising by 0.6℃. What happens if you multiply 0.6℃ by 5 or 10?
Finally, I want to talk about the insurance industry. Insurance is also one of the industries that cannot ignore global warming. According to the British Chartered Insurance Association, from the current trend, we will suffer more losses than the global GDP in the next 60 years. We can't spend all our money on dealing with disasters, so even if climate change doesn't accelerate, the turning point will come ahead of time. At present, insurance companies no longer cover losses caused by some weather disasters. They put pressure on the government to take action to stop the drastic change of global climate. !
"Little Earth" once again confirmed my research results. The extent of the deterioration of the earth's environment is not that I am talking nonsense alone, but that many environmental enthusiasts like me have the same answer.
-British environmentalist Kemmaine Duster The earth has never been in such a dangerous state. The extinction rate of biological species is so fast that I don't have time to record the detailed files of that kind of creature.
-American biologist Dolce Denefuth Human activities have destroyed one third of the natural resources on the earth. We can all find the mark of human past, the realistic environment and the prospect of the earth in Little Earth.
