Essay The Importance of Plants
546 Words3 Pages
Humans depend on plants in numerous ways. One reason we depend on plants is for consumption. Plants have the unique ability of producing their own food through a process called photosynthesis. In this process, plants are able to produce macromolecules such as carbohydrates that cannot be produced in animals or humans. In humans, the only to gain these macromolecules is to consume plant matter, or consume plant-eating animals (herbivores).
When humans consume plants, the carbohydrates, lipids, and proteins that are broken down through two forms of cellular respiration. The two processes of cellular respiration displayed in humans are anaerobic or aerobic. The deciding process used depends on the presence of oxygen. Cellular respiration…show more content…
This means that humans not only need plants for eating, but also need their created oxygen to break the food down efficiently.
In humans, cellular respiration also produces heat also needed in the body for thermoregulation, Thermoregulation that is an example of temperature homeostasis in humans, requires heat energy to maintain a relatively constant internal temperature. All the heat energy that is needed for survival would not exist without plants.
Water is also a requirement in humans, and is needed for the body to balance fluid through osmoregulation. By consuming plants, the water that they contain will also be transferred to the consumer. An example of this could be in the consumption of coconuts. Coconuts usually contain a good supply of water. The water found in young coconuts contains electrolytes and a pH level similar to human blood. This could be beneficial by providing fast hydration and are normally found in warm tropical climates where hydration is a major concern.
Other then being used for consumption, plants also provide shelter from the environment. Trees provide shade, which creates a cooler temperature that helps prevent dehydration. They also provide fruit and shelter for animals for human consumption. Trees are also cut up into wood for building houses and making tools needed for hunting and protection from predators. Humans have an advantage over animals because of our greater intelligence that permitted the discovery of tools. Without
Do you feel the unpredictable weather change every day? Global warming has become a threat to all mankind. It is now one of the primary concerns of our civilized world. We have to admit that we are the great contributor in the rapid increase of temperature in our environment. And we must be aware to the cause and effects of global warming. Trees and other plants help in reducing heat in our surroundings. It removes harmful chemicals from the soil and reduced the greenhouse gases, as it absorbed carbon dioxide and give off oxygen. These trees hold tons of water during rainy days to avoid floods and soil erosion in our cities and municipalities.
Trees are the natural habitat of animals, birds and other species. It is also a source of food, wood and paper products. They are renewable, biodegradable and recyclable. These trees are a big help in minimizing the noise, air and water pollution. The trees around us are extremely important and have always been necessary for improving the human condition, both during its life and after harvest. It is not a stretch to believe that without trees we humans would not exist on this beautiful planet. We must plant trees instead of cutting it, because trees are essential to life as we know it. They are our breath, our life and the future of the next generation. Make the earth a greener and a cleaner planet. Every tree we plant is a breath of life. Let us start digging and bury a seed for the creation of every forest start with a single seed.
