What would the world be like if there were no humans on Earth? Are humans really harmless?

Humans are not the most numerous race on earth, but they are definitely the race with the fastest reproduction and development rate, but they have not been able to give birth to other creatures that have ruled the earth for 160 million years and other creatures that are longer than human development history. wisdom.

Only human beings have not only become highly intelligent creatures, but also changed the pattern of the earth with their powerful creativity, transforming the earth into a shape suitable for human habitation, rather than blindly adapting to changes in the environment like other creatures.

Therefore, many people feel extremely proud, and some even believe in the existence of "fatalism", that the reason why human beings are different is because it is arranged, and believe that human beings are the most advanced on earth biology.

However, since the rapid development of human society, it has brought an extremely heavy blow to the earth. In terms of ecological environment, human beings cut down trees, causing soil erosion, and many animals are homeless or die due to lack of food.

With the acceleration of industrialization, the content of carbon dioxide is also increasing sharply. The global greenhouse effect not only threatens human beings, but also leads to the melting of glaciers, the rise of sea levels, and even the death of species in the Arctic and Antarctic regions.

In terms of energy, human beings with advanced technology have naturally not spared the exploitation of the earth's energy. Although people have not spared the exploitation of the earth's energy, even though human beings are now developing towards "new clean energy", this still makes up for it. There is no human misuse of resources.

According to scientists' calculations, in less than 200 years, the freshwater resources and petrochemical resources that human beings depend on will be in short supply, and freshwater resources are essential elements for life on earth. Once there is a lack of water, life will be difficult to maintain. go down.

Finally, the ever-increasing population problem has also become a major burden on the earth. There are currently more than 7 billion human beings on the earth, and the number is still growing. Experts predict that the world population will exceed 11 billion in the future. By then, the competition for resources will be even more tragic.

Due to the large amount of garbage caused by human activities, more than 100,000 tons of garbage is generated every day in one city, and more than 80% of it is plastic, which is difficult to degrade.

Scientists believe that if human beings do not cherish the earth and destroy it wantonly, then it will be human beings themselves who will suffer. If human beings even lose the earth as their home, it is impossible for human beings to find a second earth.
