Ocean Dumping is the problem which is faced by marine creatures: Ocean dumping refers to waste like chemicals, garbage, sewage and debris from construction factories or human habitations being dumped into the ocean which is lethal for marine biodiversity. Ocean dumping is also termed as Marine Pollution in which pollutants that are pre disposed from land like pesticides, fertilizers etc. are inevitably discarded into the ocean. Marine life is threatened not only by toxic waste but also through various sources of pollution.
FACTS RELATED TO OCEAN DUMPING
- Plastic is a common element which is found in enormous quantities in ocean and seas. Though it is considered harmful for the environment as it cannot be recycled and reused, but marine animals confuse plastic with their food which is even more disastrous as it is indirectly connected to humans. There are innumerable numbers of people who follow a non-vegetarian diet which even includes eating fish. In this manner the plastic that we cast off in the oceans is in turn dangerous for our health itself.
- While observing the estimates, you cannot neglect the fact that every year millions of sea birds are killed by oceanic pollution. Countless number of dolphins die each year as a consequence of becoming entangled in discarded fishing nets.
- We as human beings often assume that as maximum portion of the earth is covered with water; pollutants from the land and atmosphere will easily get diluted and will ultimately disappear in the water. This kind of consideration is a myth as in reality, they have not disappeared rather they have harmed the food chain altogether. Small animals which are present at the bottom of food chain absorb the chemicals as part of their dietary habit. The food chain functions through a vicious cycle as the small animals are then eaten by the large animals. Animals present at the upper stratification of the food chain in turn digest double amount of contaminated food which is higher in comparison to the water in which they survive.
- Oceanic world is termed as “Silent” as large number of whales, mammals, and dolphins communicate with the other aquatic animals through sound waves. You might have often wondered why fishes produce bubbles while they are moving. The ultimate reason behind this aspect is that they produce sound in order to navigate their route sand depth in the ocean water. This kind of navigation and communication is disturbed by the pollutants, which ultimately harms as well kills marine species.
EFFECTS OF OCEAN DUMPING
The oil dumped in the ocean by several tankers and ships clog the respiratory tract and grills of marine creatures which stops oxygen present under water to reach their organs. It also restricts their activities like producing food, reproduction process and sores down their body temperature. The causes of ocean dumping are very well similar to its effects.
When these toxic pollutants are prevalent in the oceanic water and are digested by creatures, it impacts humans too as they consume these sea creatures in their diet. This leads to detrimental diseases which include hepatitis, cancer and disruption of central nervous system.
Majority of dust particles polluting the ocean water settle in the ocean itself for very long period of time instead of getting diluted. As these pollutants and materials tend to degrade, they absorb the oxygen content present in the oceanic atmosphere which reduces oxygen levels and create problems for marine biodiversity.
You might have noticed garbage junkyards in certain areas in India, on similar pattern garbage patches are also being formed in the river water which mainly consist of plastic and garbage that cannot be reused.
The effects of ocean pollution that we observe in recent times are on a reduced scale, but if we collectively do not end polluting our own mother earth, various other effects are bound to occur with time. Global Warming is the biggest alarm to our senses, if we do not take note of this, then our future generation will suffer. We should leave aside the traditional approach of dumping waste in the oceans; rather there is a need to take stringent measures to tackle ocean dumping.
