Let's go a little bit in the science fiction world and imagine what can happen if people suddenly disappear and without any introductions from the planet?
==================
The answer seems terrible, of course, but is it really bad?
I think you will come out after him by concluding that the best thing that can happen to this planet is that people will actually disappear from it :)
At the moment when humans will disappear, most threatened species will return to normal levels. After 24 to 48 hours, light pollution will end. After 3 months, air pollution will begin to decline. After 10 years, methane will disappear from the atmosphere. Villages and rural roads. Fifty years later, the world's fish stocks will regress and the rate of nitrates and salt in freshwater will decline.
Between 50 and 100 years of human disappearance, forests and plants will creep up on cities and roads. The wooden buildings will collapse 100 years later, and within 100 to 200 years bridges will collapse. 200 years later, glass and metal buildings will collapse and 250 years will collapse. Dams, and after 500 years the coral will return to normal.
After 1,000 years, most of the buildings made of cement, stones and bricks will disappear. The carbon ratio will return to pre-industrial levels. In 50,000 years, most of the glass and plastic on the planet will be decomposed, and 50,000 years later, most of the effects of human existence will disappear. Some human waste will remain, which will disappear after 200,000 years, and nuclear waste will remain deadly and exist for nearly 2 million years .
