Today in class, we did future problem solving. During these lessons, I saw that what a big problem man can cause if we accidentally upset the ecosystem like over consuming of shark's fins, resulting in lesser sharks as fishermen have to kill more sharks to meet the human's consumption. These will allow the sharks' prey,such as cownose rays to reproduce faster and increasing at a faster rate, this will result a population to decrease as the rays might feed rapidly on other animals. In the end, it will caused the whole food chain to collapse.
Also, alot of our natural resources have been used excessively such as water, trees and petroleem. I have seen people wasting drinking water like spraying them on the ground. People also leave water running from the pipes for a long period of time and not bothering to close. People have also been wasting paper, resulting in more trees being cut down. This will in turn cause global warming as trees play a very important part in keeping the temperature moderate and not too extreme.
Petroleum is the necessary thing that is needed to power cars. Researchs have said that petroleum will be totally used up in the near future. Now scientists have begun to to turn to other alternative of sources usch as solar power and hydrogen.
So everyone, please use our resources wisely and when you see people wasting such precious recources, remind them not to do so as everything man do can affects the Earth.
