about taking care of future
Plants are a kingdom of life forms that includes familiar organisms such as trees, herbs, bushes, grasses, vines, ferns and mosses. Through photosynthesis, they convert water and carbon dioxide into the oxygen we breathe and the sugars that provide the primary fuel for life. Through nitrogen fixation, plants generate proteins that are basic building blocks of life. Early fossil records of photosynthesizing organisms date from about 3 billion years ago. Plants were instrumental to evolution as a whole in that they produced the oxygen that made life on Earth possible — not only by "breathing" it into the atmosphere and transforming it, but also by crushing rocks with their roots, which created soils and released nutrients on a large scale. Plants are crucial to the existence of all other living creatures on Earth, both through the systemic life-support services they sustain and the food, medicine and other material resources they provide. The total number of described plant species hovers around 250,000.
