Even though it is improbable, let's imagine that everyone on the planet was magically granted a chainsaw and was able to simultaneously chop down every tree and every plant. Although there would be a large mess, the majority of plants would just begin to grow once more, often with greater vigor than before. Many pioneer species that were being impeded by forest climax species would have a chance to obtain some sun and flourish because holes in the woods would be opened. There will be more diversity and animal habitat available when the previously suppressed seeds and seedlings take root.
The quick answer is that life as we know it would not disappear; rather, it would flourish much more.
I actually believe that the notion that man is capable of destroying the earth is incredibly arrogant and deceptive, just to really toss the cat among the birds and get some intense discourse going. When we are removed from the equation after the worst damage has been done, ecosystems will recover quite happily. They won't be exactly as they were before, but nothing is ever exactly as it was before. We are capable of upsetting many ecosystems, causing the extinction of many animals, and making many parts of the world unbearable to live in.
Have you ever considered what a world devoid of trees may look like?
Without trees, there won't be any life on Earth. Trees have a key role in all aspect of our life. And because there are 6.7 billion people on Earth, that far-off future is actually coming nearer by the day.
Even if our species is able to survive deforestation, life will be terribly difficult and meaningless. Some detrimental effects of deforestation on human existence include the following:
1. FILTHY AIR: Without trees, the air would be unhealthy for breathing, making it impossible for humans to thrive. It would be necessary for people to create gas masks that filter what little oxygen is still in the air.
The carbon cycle, a continual movement of carbon dioxide from the atmosphere to organisms and back, includes trees as a significant component. The second most valuable ingredient in life is carbon, behind water. In any event, photosynthesis is the process through which trees remove carbon from the atmosphere and transform it into energy. Following its conversion to oxygen, this carbon is either maintained inside the trees until the trees decompose into the soil, or it is released into the atmosphere through respiration.
As a result, without trees, there would be greatly less oxygen and dramatically more carbon dioxide in the air! Airborne contaminants and pollutants including carbon monoxide, sulfur dioxide, and nitrogen dioxide would be present in the unclean air, and the temperature might rise.
If the air hasn't already wiped off everyone, the detrimental impact of deforestation on soil will be the next disastrous effect. According to the Food and Agriculture Organization, 2.5 billion people depend on agriculture for their livelihood. If deforestation is successful, more people will be impacted than just those individuals. Hazardous pollutants and chemicals that trees typically filter would end up in the soil. Furthermore, soil erosion is currently avoided because trees cover the region. On the other side, the soil wouldn't be protected and would be vulnerable to the topsoil's nutrient depletion. As soil erosion became more prevalent, agriculture would eventually fail and all the soil's agricultural potential would be gone, causing humanity to go hungry.
