Why There Would be No People without Plants Why There Would be No People without Plants Plants are the most natural and valuable resources on earth. Some people consider plants to be among the oldest life forms on earth. Using energy from the sun, plants have the ability to manufacture and produce their own food. This is what brings about their unique nature. In the ecosystem, plants play an invaluable role to human beings (Lewis, 1996). Apart from the fact that plants produce a high percentage of the oxygen human beings breathe, they are an abundant source of food. Creating oxygen for human beings is the most fundamental function of plants. Since humans exhale carbon dioxide, plants use that to create oxygen that enables humans to live. This makes life possible for all living forms on earth. This paper will review the importance of plants, and how their existence orchestrates the existence of other life forms.
Plants have the task of cleaning the air. This implies that they take up all the carbon dioxide that humans exhale, and turn it into oxygen. They are a primary source of energy. This is because some individuals somewhere in the world do not have electricity as a form of energy. They provide basic heat energy in the form of charcoal and wood. It is a known fact that, without this heat source, many lives would perish (Balick & Cox, 1997).
Through plants, the soil pH and acidity is maintained. It is through the existence of shrubs and grasses that the top soil is stabilised and held in place. Through any form of erosion, soil would be rendered useless. The growth of anything on earth depends on how the soil tends to behave. Supporting life form on earth is based on the ability to grow and sustain food (Balick & Cox, 1997). This can only be possible if rich, top soil is maintained.
Through plants, it is possible for human beings to get treatment for certain diseases. Some plant species aid in the excretion of chemicals that help combat diseases. Without some of these plants, it would be next to impossible for humans to exist for long (Chiras, 2011). Isolating plant proteins is responsible for this, and through technology; many scientific breakthroughs in medicine are made possible.
These proteins are synthesised in plants. Through cellular respiration, the conversion of these nutrients into biochemical energy occurs. This further leads to the breakdown of large molecules into much smaller ones, thus releasing energy to the immediate environment. This occurs through aerobic and anaerobic respiration. Though they perform almost similar functions, the two operate under different conditions (Lewis, 1996). They are all chemical processes that require different conditions so as occur naturally.
In conclusion, all the processes undertaken in plants are designed to benefit human beings. From the provision of food to the provision of energy, human beings cannot survive without plants. The non-existence of plants guarantees the non-existence of all life form (Chiras, 2011). The conservation of this form of life is particularly crucial. It should be the focus of many leaders in this modern time. The global community should work together to ensure that plant life is conserved and preserved to ensure the continuity of human life.

...Importance of plants in solving real world problems Mosses and ferns can be described as an important foundation for the forest ecosystem as they help prevent erosion by creating a carpet on the forest floor. They are also important in maintaining the ocean ecosystem as they help provide oxygen into the sea; without them, the animals in the oceans would automatically die. Ferns are important as they help in the provision of an ecosystem to the lands; they are responsible for refining carbon dioxide in the air. Further, scientific research has shown that there are certain species of ferns that are important when it comes to the manufacturing of medicine (Germ 93). Conifers, on the other...

They provide uptake of solar energy through photosynthesis andits transmission to higher levels - to animals and humans. It would be impossible the evolution without first photosynthetic algae. The ancient atmosphere had transformed into the current atmosphere with oxygen through photosynthesis of lower plants. Therefore the organisms have left the water and colonized the land. The human impact on flora and fauna has greatly increased since the emergence of the first civilizations about 8th century BC. The first farmers have mastered the ground and learned how to cultivate the first cereal crops. Large areas of forest were cut down and burned... ...
