Discussion: Marine Debris, also known as marine trash is man-made waste that is released into oceans and coastal waters due to human activities. Marine debris brings up many environmental problems to both humans and the marine ecosystem. According to Ocean Conservancy (2014), the common types of marine debris collected include cigarette butts, food wrappers, beverage bottles and cans, plastic bags, straws and glass bottles. Although these wastes seem to come from offshore activities, studies suggest only 20% of the pollution comes from ships or offshore platforms, the rest originates from land-based activities (Sheavly & Register, 2007). We will discuss the causation and effects of marine debris and propose solutions to mitigate marine litter
You will get a stomach ache at the least. “According to some estimates, every year few millions of Americans are sickened by polluted water” (Environmental Pollution Center). Few millions of Americans are sickened every year and majority of them are children. Unclean water and poor sanitation have claimed more lives over the past 100 years than any other cause. The water-crisis claims more lives through disease than any war through guns.
The release of excessive carbon dioxide gas has been absorb over time by the ocean. It may be decrease the rises in temperature due to global warming but new research state that the emission of large numbers of CO2 into the seas is changing water chemistry and threaten the marine organisms, including those at the lower conclude of the food chain. Carbonic acid formed when carbon dioxide dissolve in ocean. It causes acidity of ocean increase. The aim of this report is to investigate that how acid acidification in ocean threaten the aquatic life.
The Ganga river basin from the Haridwar to Calcutta, being the largest in the country occupying about 26 per cent of the total geographical area is regarded as one unending sewer which is fit only to carry urban liquid waste, half burnt dead bodies, pesticides and industrial wastes. Nearly 312 industrial units are dumping their waste into the river, of which only a dozen have effluent treatment facilities. The 27 cities situated along the basin contribute to the discharge of 902 million litres of waste water to the river every day. The water of Ganga affects the health of 250 million people of northern India. Of the long stretch of Ganga, it is most polluted in the state of Uttar Pradesh.
Environmental pollution is the result of improper disposal, which shows forth our unsustainable usage of resources. This is evident with the large amount of plastic irresponsibly disposed in the sea, the excessive burning of fossil fuels that contributes to air pollution and all the unsustainable management of factories leading to large amounts of waste material discharged into water bodies causing heavy hazardous contamination. All these excessive pollutants added into the environment, disrupts the natural cycle leads to a myriad of negative repercussions and drawing attention to invoke change so as to prevent what is preventable in very first place. We have seen from history how environmental pollution can lead to irreversible long-term damage: Love Canal Case and the derivation of Minamata disease. In recent years, we see how soil pollution has led to huge issues with regards to health, economics and ecosystem: mercury poisoning due to mercury being trapped in grains produced.
Plastics in our oceans is the most dangerous form of pollution in the 21st century In Los Angeles alone, 10 metric tons of plastic fragments—like shopping bags, straws and soda bottles—are carried into the Pacific Ocean every day. Over the last ten years we have produced more plastic than during the whole of the last century. 50 percent of the plastic we use, we use just once and throw away. Enough plastic is thrown away each year to circle the earth four times.We currently recover only five percent of the plastics we produce.The average American throws away approximately 185 pounds of plastic per year.Plastic accounts for around 10 percent of the total waste we generate.The production of plastic uses around eight percent of the world's oil
It is no secret that humans have a large issue when it comes to plastic waste, as we produce over 300 million tons of plastic each year, with 50% used once and thrown away. But where does all of our plastic debris go once we discard of them in the trash? The answer, oftentimes, is the ocean. According to a UC Santa Barbara study, over 8 million tons of plastic is thrown into the ocean each year, and since 10% of our trash ends up in the ocean, 90% of which being plastic waste, it is estimated that 5 trillion pieces of plastic, weighing 250,000 tons, are floating in our oceans right now. However, when you visit your local beach, it is unlikely that you see mounds of trash washing ashore.
This is due to their carcinogenic and toxic properties (ATSDR, 2013). As the strict legislations have been introduced by various environmental protection agencies in the developing countries, the removal of heavy metals from water and wastewater becomes the subject of considerable interest in recent years (CPCB, 2008; WHO, 1996). Manganese, nickel and copper are the common heavy metal contaminants and pose significant threats to human health. Manganese poisoning causes various severe health problems in vital organs of humans such as neurological disorders and harmful impact on human respiratory tract due to prolonged inhalation of Mn(II) (ATSDR, 2012). Gastrointestinal distress, pulmonary fibrosis and skin dermatitis are the most noted diseases in addition to lung and kidney problems associated with Ni(II) ion poisoning (ATSDR, 2005; US EPA, 1986).
In recent years, Marine pollution has become a global concern. The marine environments are affected by either point or non point source pollution. Chemicals such as oil-based products, pesticides, fertilizers, heavy metals, accidental oil spills, runoff from coastal areas and plastic materials (Haynes et al., 2000; Wiese and Ryan, 2003; Rios et al., 2007; Lionetto and Maffezzoli, 2008; Lionetto and Frigione, 2009; Prouty et al., 2010 ) all impact marine environments. For the last three decades, the industrial and human activities in the coastal area of Saudi Arabia have dramatically increased and resulted in the continuous invasion of different types of pollutants including heavy metals, and also, from four oil refineries located
According to World Resources Institute Energy, it was estimated that 3.6 million tons of oil spilt in to sea annually, mainly as a result of shipping accidents involving oil tankers and deliberate flushing of tanks and engines as well as offshore and onshore oil well blowouts. In my opinion, marine pollution is a crucial issue that should draw concerns. Marine pollution will cause a great negative effect not only towards living creatures but also to the natural ecosystem. Oil spillage has become quite a common phenomenon in Malaysia. Normally, it only occurs when there are shipping accidents especially on the busiest traffic route like Straits of Malacca, accidents tend to happen
