I have 2 opinions:
1. Earth with no people can still flourish, because sometimes the reason for pollution and destruction here on Earth is humans. A vast population and pollution of the world is the result of over thirty millennia of struggle. Due to lack of discipline and no symphathy/concern for the environment makes our planet worse. The planet would survive without us and still make the world green and healthy, and including the production of extinct animals.
2. On the other hand, Earth has no life and meaning without humans. The reason why Earth is unique because of humans who take care and give importance of it. Meanwhile, lacking human oversight where plants may take over things/buildings and consume spaces, no ones there to cut them back. Places create molds, windows became blurred, and rotten. A messy place it is. Global temperatures and sea levels begin to fall. Wildlife colonizes towns and places will be consumed by scrubs, vines and trees. Plants will not grow because there's no CO2 that humans only produce. The Earth is nothing without humans. The Earth must be taken care of. We humans certainly have to figure out how to survive the planet and make it better.
