In a world without plants, life as we know it would end.

We would cease to exist.

Plants feed on minerals and carbon dioxide to grow. Their bodies are rich in glucose that builds the basis of the food of animals and expel oxygen during photosynthesis, and that oxygen is what the animals need to breathe. Animals cannot live without plants.

And we are just another species of animal.

If the plants disappeared, the herbivores would starve to death. If there are no herbivores, the carnivores would also starve to death. Mushrooms and insects would disappear.

But our planet would not be without life.

Some bacteria could survive.
