It’s an impossible scenario, but let’s assume that somehow every human on earth was given a aaa First slide Tmg Studios Epic Bear Move Shirt and was miraculously able to chop down ever tree and cut down every plant simultaneously. It would be a huge mess, but most would simply start growing again and many would grow with more vigor that before. Because gaps would be opened in forests, many pioneer species that were being inhibited by forest climax species would have a chance to get some sun and grow. As the previously suppressed seeds and seedlings get going, there will be an increase in diversity and more habitat available for animals. So the short answer is that all life on earth would not end, it would actually grow with more vigor. Actually, to really throw the cat amongst the pigeons and get some animated conversation going, I think that the idea that man is capable of destroying the earth is highly arrogant and misleading. We are capable of upsetting many ecosystems and causing the extinction of many animals and we can make many parts of the world miserable to live in, but take us out of the equation once the worst damage has been done and ecosystems will bounce back quite happily- not exactly as it was before, but then nothing is ever as it was before.
