Causes of ocean pollution



Ocean pollution, also referred to as marine pollution, is ocean water pollution caused due to dumping of industrial, agricultural, or residential waste into the vast ocean body. Oceans are large water bodies, which provide shelter to millions of marine animal and plant species. Ocean water pollution is a serious threat to the basic survival of these marine species owing to habitat destruction. Most of the ocean pollution causes are land based, wherein human intervention is involved, either directly or indirectly. Read more on marine biology.

Ocean Pollution Causes and Effects

There are several causes of ocean water pollution, and each cause in turn has several adverse effects on various life forms. Life forms affected by ocean pollution include humans as well, but then its the humans who have a dominant role in pollution of water, air, as well as land. Mentioned below are some of the prominent ocean pollution causes, and their effects on marine life forms and humans.

Ocean Pollution Causes
One of the major causes of ocean pollution is the discharge of crude oil, accidental or deliberate, in the oceans. This happens in course of transportation of ships, when these ships discharge their waste in the ocean. Ocean pollution statistics give the gruesome picture of the hazard the marine life is facing. This problem is faced by all the oceans of the world. Transportation of vessels carrying various ores can also lead to pollution of the water body when these ore sediments are accidentally dumped in it.

Statistics reveal that approximately 45 percent of ocean water pollution is caused by marine transportation, while 32 percent is caused by loading, discharging, and flushing of oil tankers. On the other hand, the ocean pollution caused by natural seeps, which is the major natural pollutant, accounts to only 8 percent of total ocean pollution. Oil spills, which are estimated to be close to around 900,000 metric tons annually, are major pollutants of ocean water.

Another important cause of marine pollution is industrial waste dumping. This toxic waste contains various contaminants including mercury, polychlorinated biphenyl (PCB), and polycyclic aromatic hydrocarbon (PAH). Garbage dumping, i.e. channeling of human waste into the ocean as a method of garbage treatment, is another major cause of ocean pollution, which can be attributed to sheer negligence on our part. It doesn't just end there. The polluted air, containing gases like carbon dioxide and carbon monoxide also leads to ocean water pollution.

Ocean Pollution Effects
Ocean pollution is hazardous for marine life. Oil spilled in oceans is disastrous for all forms of marine life including coral reefs, fish, and marine plants. Coral reefs are in fact the worst affected as excessive ocean pollution and global warming threaten to wipe them off the planet within a few more years. Ocean pollution leads to depletion of oxygen dissolved in water, which in turn makes it difficult for various sea animals to breathe underwater. Humans are not left out the hazardous effects of ocean pollution as marine life is a major source of food for humans.

Ocean Pollution Prevention

Prevention of marine water pollution emphasizes on identifying the various ocean pollution causes and finding a solution for them. These include

    * Ensuring that there is no leakage of crude oil from tankers by regular monitoring of vessels by proper agencies.
    * Declaring deliberate discharge of crude oil by vessels and industrial waste by industries on land as an offense with a significant penalty.
    * Ensuring that garbage produced by humans is treated properly instead of just dumping it in the oceans.
    * Ensuring that the amount of air pollution, which causes phenomena such as acid rain, is lessened if not totally curbed.
    * Understanding the importance of marine life for us and making sure that we don't cause harm to them.

More importantly, rather than just talking about such measures, proper implementation at all the levels has to be ensured if we intend to make the crusade of 'clean oceans' successful.

These were some of the ocean pollution causes, their effects on various life forms, and the preventive measures we need to take to mend the damage that has been already done. We can't just leave the prevention part to the authorities, in fact, it's the steps at individual level will ensure that no further damage is caused. We need to understand that irrespective of what development we achieve in various sciences, success will always elude us when we take on nature.





Top video game developers





Video games are an obsession for many people, and this multi-billion dollar industry has gained even more prominence, thanks to the advanced video game consoles that are available in the market today. A whole new segment of gamers have opened up in the last few years, and video game developers are increasingly creating video games that cater to people of all ages.

A video game developer is a company that creates and develops the software of a video game. Developers can focus their efforts solely on creating games for a particular console (like Sony PlayStation 3 or Microsoft Xbox 360), or they can be companies that develop games for all platforms. PC games are also very popular amongst gamers from all around the world, so this is another segment that developers work towards serving.

The Top Video Game Developers Around

One needs to understand the difference between third-party developers and independent developers, first. The company that sells a video game, and markets and advertises it is known as the publisher. Many times, a publisher company hires a third-party developer to create the software for the game, and both these companies work in tandem. The publisher benefits because he gets expertise in the video game development process, and the developer benefits because he does not have the resources to market the game, and these resources are then provided by the publisher.

Independent developers are small-time developers who do not rely on a publisher to get their game in the market. Most developers who work to build games for smartphones and tablets fall in this category. Their promotion is strictly carried out through word of mouth and free advertising over the Internet. There are some large scale companies though, that carry out their own developing and publishing operations too. These developers have the resources to do so, and the best example of such a company is EA Sports. With that being said, here is a list of top video game developers.

Rockstar North Ltd.
They were earlier known as DMA Design Ltd., and the company is based in Edinburgh, Scotland. The most famous offering by Rockstar North is the Grand Theft Auto Franchise, which is one of the best selling and most popular game series ever. The company has produced around 35 games since its inception in 1988, and these games have featured across a variety of platforms.

Electronic Arts (EA)
EA is perhaps the biggest video game developer and publisher in the world today. It was founded in 1982, and has produced hundreds of games for all possible platforms in this time span. There are various subsidiaries of EA as well, and each of them caters to a different segment in the video gaming industry. EA is to the video game world, what Apple is to the smartphone world. EA Sports is a major subsidiary that offers sports games, and the FIFA series is the most successful and well known of the lot.

Ubisoft
Ubisoft Entertainment SA is based in France, but it has subsidiaries and development offices all around the world. The company was founded in 1986 and its biggest studio is located in Montreal, Canada. The number of games available are very vast in number, and there is no gaming platform that they have not catered to. Some of the most famous games by Ubisoft are the Assassins Creed games, the Prince of Persia games, and the Tom Clancy's series of games.

Konami
Konami Corporation is based in Japan, and it is one of the video game developers that has come off the boil in the last few years. There are several other industries that the company services, and it is not the video game behemoth that it once was. The company was founded in 1969 as a jukebox repair and rental company, so there is a lot of history here. The company headquarters is in Tokyo, and out of the hundreds of games that they have produced, the most popular ones today are Metal Gear Solid and Pro Evolution Soccer.

These were just a few of the best video game developers around today. Some more excellent video game developers are as follows:

    * BioWare
    * Blizzard Entertainment
    * Capcom
    * Clover Studios
    * Epic Games
    * Lucas Arts
    * Microsoft Game Studios
    * Namco
    * Naughty Dog
    * Nintendo
    * Santa Monica Studios
    * Sega
    * Sony Computer Entertainment
    * Square Enix
    * Valve

All of these great video game developers have been providing us with the best video games for many years now. This is an industry that will never go out of vogue, and as newer platforms hit the market, the demand for these games will only rise. So if you are looking to buy some great video games, look for the ones that are made by these developers in particular.
