Have you ever gone to Mana Mana? The sand you are stepping on may be the sand that tons of dead fish once lied on. Some people say that there was a fish kill in Mana Mana before. Why are there fish kills? How does it affects us? How can it be solved?
Firstly, why are there fish kills? Fish kills may be caused by water pollution, oxygen depletion, infectious diseases, parasites. There are a lot of possibilities, but water pollution includes a lot of the possibilities and is probably the most possible and common reason.
Water pollution, what is water pollution? It is a pollution which occurs when too much foreign substances go into water, damage the water quality and make the water non-potable- undrinkable or dangerous for organisms to live in. Pollution can go into water in many ways- acid rain, inroad soil, runoff containing fertiliser or other substances, chemicals released from industries, sewages… Water is easily polluted and is really hard to be cleaned. It is because water is the “universal solvent” which means it dissolves many things. This causes water to dissolve almost everything that gets in its way, and by the time it damages the quality of itself and get polluted. This also causes water to become difficult to clean.
This ability of the “universal solvent” causes itself to dissolve almost everything that gets in its way, and by the time damaging the water quality and gets polluted, and difficult to clean. This ability of the “universal solvent” causes aquatic life to always be difficult. The reason is that water is too hard to keep itself clean and the aquatic life is then dangerous when that lot of variety of chemicals dissolved in water- which may be harmful- flowing around in water reaching different water areas easily, without being seen. Therefore, it is really important to keep water resources clean.
People in developed places don’t treasure water as they can get it by only turning on the tap. They over consume, waste water, and pollute water. You may think it doesn’t matter, but have you ever think of how the water pollution affect all of the natural environment? Water pollution is a serious problem now, not only because water is very polluted, but also because it affects the natural environment and wild animals, a lot. Water covers 70% of Earth’s surface and covers 99% of the living space on Earth. It provides nearly 50% of Earth's oxygen and 20% of the world's protein supply, and supports 50% of the animals living on Earth. Now 2/3 are endanger because of water pollution.
You may not care about the natural environment as long as you are safe, but do you know that water pollution also affect us, humans, and you may not be safe? For us, living in developed places, we may not care, but over a billion of people can’t get clean water as easy as us, so they drink water that is not clean and then get sick or die. You may be a murderer. If you don’t care about others’ health or life, I bet you still care about yourself. Are you having fish for dinner today? Look at the fish you’re eating, it may be a fish that’s from a river or sea filled with oil of the boats, filled with rubbish and all that harmful materials you flush or wash away. You may be eating a fish from that horrible environment you created yourself. You don’t eat fish? Beaches, beaches that have water pollution gives you rashes, ear aches, pink eye, respiratory infections, hepatitis, encephalitis, gastroenteritis, diarrhea, vomiting, and stomach aches. That’s no day at the beach, is it? So you are not going to stay safe forever with water pollution.
If you don’t care about health, do you care about money? Water pollution can damage economy as it is expensive to treat and clean the water in order to make it potable, and it’s also expensive to prevent water contamination. I bet you won’t like to pay for ten dollars for a bottle of water. People are sick because of drinking polluted water, they need medication. Medication uses a lot of money and resources. Also, beaches which may be tourist attractions are closed- because the water pollution at the beach gives people health problems like -and may decrease tourism. For example, thousands of beaches are closed in the US every year. Water pollution affects everything. Therefore, bear in mind, water pollution is a serious problem and it is really important to keep water resources clean.
Anyway, worrying is useless, why not think of a solution to solve the problem? How can we solve the problem of water pollution? There’s always a solution. We should start with personal little things. Firstly, we still have a lot of clean water, save them, treasure them, use them in an appropriate way. Secondly, don’t dump junks into the sea, no matter when we’re on a boat or on the shore. Thirdly, we can volunteer to pick up rubbish on the beach which may go into the water and pollute them. Factories are one big part of water pollution too, and they’re now working new ways and policies to help with the water pollution. Many countries now have laws to protect water. Also, there are organisations now to tell people and clean water and save marine life. Also, instead of dumping everything from the sewage into the ocean, we can make recycle the water like how Singapore does, making potable water again. Although it may cost quite, it is an action we should take for a better future of us humans, animals, environment and economy… There are a lot of things companies and factories can do, but it is always a responsibility of all of us.
Back to fish kill in Mana Mana. What do you think causes that to happen? As you should know, Mana Mana is in Singapore, Singapore have always been reclaiming land. When they reclaim land, the waste of the machines may be releasing harmful materials into the water and this may be the cause to the fish kill. Singapore is also a trading country so ships are going in and out, and that may cause an accident of oil leakage.
Water pollution is almost the most serious problem, it affects us environmentally, affects our health, affects our economy. If water pollution is going to go worse, many bad and sad things are going to happen. For example, two-third of the endangered marine animals may all die leaving one-third of all the marine animals existing now; Water will be high-priced; More people will catch diseases due to water pollution… So bear in mind and be optimistic with working for a better future of water pollution.
