All plants live and grow by photosynthesis. Some animals eat other animals, but if you follow the food chain back you will find that green plants are always at the base. Animals and plants die and decay, releasing minerals into the soil and CO2 into the air for green plants to use for photosynthesis. If green plants were to suddenly disappear, then so would virtually all life on Earth - including Homo Sapiens. Green leaves are thus the powerhouses - the great driving force for Life on Earth.
Photosynthesis is the life generating chemical process.
