There are many different types of energy in the world. These are classed into two groups: renewable and non-renewable energy. Renewable energy can be used as a fuel and these types of energy can be used over and over again. They will never run out whereas non-renewable energy has a lifespan. Non-renewable energy can also be used as a fuel. These types of energy are finite. They will not last forever. The various non-renewable sources of energy are coal, oil and natural gas. These fuels are called fossil fuels. As said by the name, this type of energy is derived from fossils. Fossils are dead animals or plants which have been preserved in the ground for millions of years.
For this reason, plants are needed to create fossil fuels, which are used throughout the world by every country. If photosynthesis didn’t occur, there would be no plants to be preserved in the ground, to be used for fuel. As fuel is needed to run all types of things in the world such as factories and is needed in cars, plants are essential to create this fuel. [1]
Today, clothes are made out of many different materials such as polyester, silk, nylon and fur. One other main materials used for clothes is cotton. Cotton essentially grows on plants. There are certain plants which create cotton. These plants photosynthesise just like other plants and stay alive due to this. If the process of photosynthesis didn’t happen, there would be no cotton hence no clothes made from cotton. Many clothes all over the world are made from cotton and most humans wear cotton clothes. Due to photosynthesis, there is cotton and there are cotton clothes which is another important reason why photosynthesis is needed as it affects many factors globally. [1]
There are four factors which are needed for photosynthesis to be present as mentioned before. These are: light, water, pigment in the leaf, usually chlorophyll and carbon dioxide. Carbon dioxide is a factor which globally affects the world’s climate.
Global warming is the most talked about topic in the world right now and it is increasingly affecting the world’s climate, making it hotter in some places and colder in others. Not many people are trying to do anything about global warming but there are others who are doing their very best. Plants take in carbon dioxide and global warming is happening due to the excessive amount of carbon dioxide and other gases, but the main being carbon dioxide. Plants are working the hardest to keep global warming at its lowest as they take in the carbon dioxide in the atmosphere because they need it for photosynthesis. If there was not photosynthesis, there would be an increase in the affect of global warming and it would affect the world a greater deal more. [1]
Carbon dioxide is also affecting the rain. The rain becomes acidic due to many gases such as carbon dioxide. This acidic rain is affecting the environment by killing fish and trees. With the use of plants taking in carbon dioxide, this is reducing otherwise the rain would become even more acidic. [2]
Electronics such as computers take up a lot of energy to run. They use a lot of electrical power to run which comes from electrical lines coming from factories. The usage of electricity is so high that researchers are trying to find another way of producing power for electronics to work on.
The first type of research is working with computers. To make them more efficient, smaller parts are needed and this is created by using smaller molecules. Furthermore, people are trying to use the same principle that plants do when using energy. Plants use light energy and convert it into chemical energy during the process of photosynthesis. Researchers are trying to use the same principle but convert light energy into electrical energy just like some calculators work. [1]
Photosynthesis involves light which is absorbed by the chloroplast in the leaf. The tissue in the plants is somewhat damaged but the process still continues. These cells are then essential in the process of photosynthesis. Researchers have been trying to use this principle of photosynthesis to improve medical care for patients with cancer. It is apparent that conditions such as skin cancer are caused by the sunlight.
The researchers have tried to find ways which involve killing the cancerous tumour. This is done by localizing substances similar to that of chlorophyll. Then light is shined upon this tumour and photochemical damage kills the tumour. This does not damage any of the other surrounding tissue, so it only kills the cancerous tumour. This can help the medical world a lot hence it is another very important issue, affected by photosynthesis. [1]
Many animals and humans live in houses of dens of their own but in the rainforest or any other ecosystem, animals and people’s shelter is the trees and plants. In the Amazon Rainforest, the tall trees in the emergent and the main canopy layer shelter animals and the local habitants, the Amerindians, from the rain. If plants didn’t photosynthesise, they wouldn’t grow as tall as they do; therefore they wouldn’t give animals and humans shelter.
Lastly, the waste product of photosynthesis is oxygen. This isn’t much of a waste product to humans and animals as they need it to live. Just like plants need carbon dioxide, humans and animals need oxygen to breathe and live. Also, the fact that humans breathe out carbon dioxide, adds to the affect of photosynthesis. They both need each other.
Overall, photosynthesis is very important for the world and nature. We all need photosynthesis to occur in order to live and have the things we have now. Photosynthesis also has a global effect as it lowers the affect of global warming, hence our climate doesn’t fluctuate too much. In the humans and animals need plants and plants need humans and animals. It is one big cycle.
