As we all know, although the history of human civilization spans only a few hundred years, in this short period of time, our impact on the earth has reached an unprecedented level. In the case of rural rivers, for example, the once crystal clear rivers where fish roam freely have become memories. In the old days, people could jump into the river in their daily clothes and swim in the hot summer months. Today, however, the river is muddy, the fish are long gone, and the garbage and algae floating on the surface of the river are shocking.
Since humans set foot on this land, the earth's environment has begun to change irreversibly. The discovery and use of fire not only enabled humans to cook food and build tools, but also opened the prelude to large-scale deforestation and the construction of shelters. With the advent of the first industrial revolution, coal became the source of power for transportation such as trains and automobiles, and was mined in large quantities. Nowadays, under the wave of the information age, we have turned to mining various mineral resources to manufacture sophisticated electronic devices. However, all this is unknowingly depleting the planet's limited reserves of resources.
The wanton destruction of the environment by human beings has scarred the planet. In recent years, the problem of global warming has become more serious, and its consequences cannot be underestimated. The melting of polar glaciers has led to a rise in sea levels, which could not only trigger natural disasters such as tsunamis, but also threaten the survival of some low-altitude countries. Even more worryingly, the permafrost that had been sealed for tens of thousands of years is also beginning to melt. Scientists have found the remains of many ancient creatures in these thawed permafrost, such as the well-preserved giant wolf head found in the Siberian region. These findings suggest that global warming is bringing these frozen creatures back to light.
But the problem is that as global warming continues to melt permafrost, those ancient viruses and bacteria buried in it may also be released into human society. Once these viruses flow into rivers around the world with melting glaciers, the consequences will be dire. We may be facing an unprecedented health crisis.
Global warming is a nature-related phenomenon caused by the accumulation of the greenhouse effect. In terms of specific data, the average surface temperature of the Earth has increased by 0. per decade since 188007°c（0.13°f）。Although this number may seem small in a short period of time, its cumulative effect becomes significant over time. Especially since 1981, the rate of change in temperature has more than doubled to 018°c（0.32°f）。
In addition, based on the analysis of data over different time periods, it can be seen that there is a correlation between the global warming trend and the timeline of the industrial revolution. During the period 1851-1935, the period of the Second Industrial Revolution, the global temperature increase ranged from -04°C to +06°C. And between 1936 and 2020, the period that overlaps with the Third Industrial Revolution, the range of global temperature increases rises to +06°C to +15°C and above. These data show that average surface temperatures have been higher than pre-industrial values in recent years.
Global warming will lead to a series of environmental problems, such as melting glaciers and permafrost, rising sea levels, etc., which will not only disrupt the balance of natural ecosystems, but also affect human health and even threaten human survival. In addition, due to the increase in the temperature of the continent caused by terrestrial greenhouse gas emissions, the temperature difference between the continent and the ocean has become smaller, which in turn has slowed down the air flow and the haze cannot be blown away in a short time, resulting in an increase in haze weather in many cities, affecting human health.
The earth is our only home, and every living thing and every forest deserves to be cherished and protected. As part of nature's ecosystem, we are at the top of the food chain, but we do not have the power to destroy the living space of other organisms. Ecological balance is the cornerstone of nature, and if we break this balance, we will end up with a harsh backlash from nature. Therefore, protecting the environment and cherishing resources is not only for the sake of the planet, but also for the future of ourselves and future generations. What do you think about this?
