Pollution and Marine Life
There is plenty of marine life out there living in the oceans, but many of them are struggling to survive. They have been adversely affected by ocean pollution and if we don’t help them the chain reaction could be very serious for all living things including humans.
Toxins are very common in our society and they are destroying the habitat in the oceans around the world. They come from a variety of resources including the factories and oil production. One small oil spill in the ocean can profoundly ruin the life types that are living there. When you think about those larger oil spills that have occurred over the past several decades it is unbelievable the amount of marine life that has been destroyed.
Those that aren’t directly destroyed by the toxins may still suffer an ill fate. This is because their habitat becomes smaller and smaller. They have to compete for what little space is left that can be lived in. They also find that many of their sources of food have been destroyed along the way.
The amount of oxygen that is created and used by marine life is also affected. When there are various forms of organic waste that get into the ocean such as phosphorus and nitrogen there is going to be less oxygen found in a given location. The ecosystem simply won’t be able to effectively handle that volume of organic matter.
Algae is very common in bodies of water including the ocean. In fact, it can be a source of food for many forms of marine life. Yet when there are too many forms of organic waste in the water then algae can take over. It can kill off other forms of organisms and that too will quickly upset the balance of things in the water.
Ocean Pollution Effects on Marine Life: Problems with Land Pollution
The land pollution is directly related to problems with ocean pollution. As the chemicals get into the water they tend to cause sediment to be contaminated. This gets into the water due to runoff. This will destroy the coral reefs and areas of grass that grow in the ocean. So many forms of marine life rely on those sources of food for their survival.
Approximately 80% of the pollution that affects the ocean comes from the efforts of humans. There are so many issues that directly relate to problems in these areas. They include greenhouse gases that are destroying the ozone layers. It is believed that at least 40% of the marine life out there in the oceans has been adversely affected in some way due to ocean pollution.
Yet it isn’t just the fact that marine life forms are dying either. Studies show that their overall health and well being is suffering due to ocean pollution. This means that even though many forms of marine life are surviving their genetics and their overall methods of survival are being reduced from what they once were.
Toxins also affect these mammal marine life forms due to the foods that they eat. When they consume smaller fish for example that have toxins in them it is passed through their own bodies. It also gets into the milk that they offer for their young and that is part of why there is such a high mortality rate among so many of them. It is a chain reaction that continues to touch every level of marine life from the very small organisms to the huge mammals that are found in the oceans.
Marine life is directly linked to the overall survival of humans too. For example there are many forms of seafood with high levels of mercury in them. Humans that eat them can become very ill too. This is just one of the many reasons why well all have a responsibility to reduce ocean pollution.
