Vegetable planet

Despite having lived with them for more than two hundred thousand years, there are still plants about which we know nothing. But they are of the utmost importance: the plant kingdom not only represents 99% of all living beings on the planet and is the basis of the food chain, but they also provide much energy and all our medicines. So what would happen if they disappeared? Human life would be extinguished in just a few weeks. What if we disappeared? The Earth would simply be covered in green.
