What are the dangers of cutting down trees? Please, 3Q

If there were no plants on earth, we humans and other life would cease to exist. Wildlife depends on plants and can also protect them. Take birds as an example, 90% of birds feed on insects, and many beneficial birds are the guardians of crops, trees, and natural enemies of pests.

100 tree insects can eat the leaves of a large pine tree in ten days, while a pair of large can eat more than 400 insects a day. Without these beneficial birds, pests would be infested. On Earth, human plants and animals are actually one and the same"Biosphere"、"Circle of friends", no one can do without anyone.

The reason why human beings can survive on the earth is because of ecological balance. The Earth provides us humans and all forms of life with a life support system – air, water, proper light and heat, and energy, to name a few. In fact, this pristine ecological balance is extremely rare on a global scale, and we may only see it today in places where humans have not set foot in it.

While the natural environment provides environmental resources for human survival and development, it has been destroyed by human machines. The outlook for humanity is optimistic only when the natural environment is in harmony with an ecological balance.

Soil erosion is serious Lack of oxygen and natural filters. The ecological environment has been forcibly occupied, and the laws of the ecological cycle have been destroyed. The temperature can change, causing an unstable change in the climate.

The waste of the trees is burned after they are cut down, causing environmental pollution.

Desertification. There is a lack of oxygen supply, and there is also a lack of a barrier against wind and sand fixation. The ecological environment is occupied, and the laws of the biosphere are destroyed.

The temperature rises, creating irregular changes in the climate. The debris of the felled trees is burned, which pollutes the environment. Humans will slowly die of lack of oxygen!

The birds have lost their homes, the earth has no flowers and birds, and it will be us humans who will be punished in the end. Also, we can't see the forest anymore, and we don't have any wildlife

If you do this, you will lose your home to wildlife, you will make the air quality worse, and you will cause sandstorms.
