In recent years, human beings have paid more and more attention to the topic of environmental protection and expressed concern about the increasingly harsh environment. Many people also like to speak for the earth and ask everyone to save the earth.
Does the earth really need to be saved? I don't think so.
Look at the earth's self-regulation ability, and we will find that the earth does not need to be saved at all.
Temperature regulation
0The environmental protection topic we are most concerned about is the change in temperature.
In recent years, the trend of global warming has become increasingly serious, which has caused many people's concerns. But is this really a terrifying challenge for the earth?
is not the case.
In the history of the earth, the number of times global temperatures have changed many times.
Ten thousand years ago, the earth was in the closest ice age to us, and the whole world was in a state of cold weather.
Five thousand years ago, the whole world became extremely warm, and the global temperature was far more than it is now. According to research, Henan at that time was a subtropical rainforest, and even elephants, which were similar to the environment in Myanmar today.
500 years ago, the earth entered the Little Ice Age again, and the world was extremely cold, and even Hainan Island could snow.
Despite so much experience, the earth is still there intact. Let me ask, what can I do if I warm the climate of ?
Food chain balance
In nature, animals are divided into carnivorous, herbivorous and omnivorous. When we see carnivores prey on herbivores, we feel pitiful for herbivores.
However, in nature, this is just a rule to maintain balance in the food chain.
students will talk about: Taking a very simple ecosystem as an example, when the number of wolves on the grassland increases, the number of sheep will decrease. The sharp decline in sheep will lead to an increase in the number of pastures. Of course, this will not lead to the extinction of the sheep. When the number of sheep decreases, the wolf will also decrease due to food scarcity, and because of enough forage, the sheep's living environment will improve, and the number will begin to increase. The increase in the number of sheep will allow the wolf to have a richer food to reproduce in large quantities, and it will return to the state we mentioned at the beginning.
All of this is being adjusted by the laws of nature, so why do we need human resources to assist?
Air content
Same thing, the same is true for the air on the earth.
We say that the content of carbon dioxide is increasing, but it is definitely not the highest value in history. In ancient times, the earth also had periods of relatively high carbon dioxide content.
In this case, the temperature is indeed very high, and many animals cannot bear it and become extinct. On the other hand, plants are easier to perform photosynthesis and grow faster. Increased photosynthesis will allow them to release more oxygen, which will eventually lead to a much higher oxygen content than it is now. At this time, animals have abundant plants to eat, and the high oxygen environment makes them huge and eat more plants, resulting in large-scale death and even extinction of plants. The earth has returned to the stage of greenhouse gas surge.
Today’s greenhouse effect, today’s global warming is just a common occurrence for the earth that has experienced 4.5 billion years. Just like a person who has been working overtime until late at night after many times, will he not be able to bear it when he goes out at 5:30 because he put on makeup at work after get off work?
Summary
In fact, those disasters that make us fuss are no longer painful to the earth. No matter how humans "torture" the earth, it can continue to move forward with its powerful self-regulating energy.
These disasters are just a test for us humans.
The earth does not need to be saved, only human beings need to be saved.
Similarly, the increase in carbon dioxide and climate change on the earth, human factors cannot be ignored, but there is also the rotation cycle of the earth itself. Perhaps, we are just in another heating cycle.
What we need to do is to survive this global warming, and even prepare for the test of the ice age in a more distant future.How to survive the continuous cycle of the earth is the greatest test for mankind.
