Reflection

After what I had done researching on this research topic, I had decided to come to a conclusion. One important thing that a person will need to know is that everything in an ecosystem is related to one another. Any problems affecting one of the components of the aquatic ecosystem will lead to other problems occurring, it is a continuous chain of problems. Thus, it is important
for us, human beings to maintain the health of the ecosystem. Human beings had depended on aquatic ecosystems for many years, thus it is our duty to protect them and continue using them for our basic needs.

Aquatic organisms and the ecosystem represent a substantial part of the earth's biological diversity. The association of man and aquatic ecosystem can be found back many centuries ago. It is not surprising that the first sign of civilizations and villages are traced to wetland areas, as aquatic ecosystems provide food and water for the people living near them. The flood plains of the Indus, the Nile delta, and the Fertile Crescent of the Tigris and Euphrates rivers provided man with all his basic necessities. Water is required for various purposes like drinking and personal hygiene, fishing, agriculture, navigation, industrial production, hydroelectricity generation and recreational activities. The wide variety of aquatic ecosystems can be profitably used by humans for various needs and for environmental amelioration. Ever-increasing population and industrialization have inflicted serious environmental pressures on these ecosystems and have affected them to such an extent that their health had been affected greatly over the past few years.

Therefore, I feel that there is a need for everyone to do their part in protecting and ensuring that aquatic ecosystem will remain healthy. Affecting the health of an aquatic ecosystems can be caused by many human activities. The release of chemical waste from factories can kill and wipe out many species of organisms. Global warming can also leads to the extinction of aquatic organisms.

As I had said earlier, changes in the temperature can kill the organisms as they are not suited and could not adapt to the temperature change in such a short time. Global warming is the increase in the average temperature of the Earth's near-surface air and oceans. Global warming causes the temperature of Earth to rise over the years because of what we call the greenhouse effect. It is being caused by the release of harmful gases like carbon monoxide into the environment by factories. Humans can thus be said to have caused global warming.

Imagine that all the freshwater on Earth is being polluted by our activities, how can we still survive, without freshwater for drinking and bathing, let alone those aquatic organisms? With all the fish dead in aquatic ecosystems, there will be definitely a shortage of food around the world. Therefore, I felt that my research had helped me in understanding the importance of saving aquatic ecosystems and through the research, I had also gained knowledge about the causes and effects of having an unhealthy aquatic ecosystem.
