//** So this is what pollution does to marine life ! **// media type="custom" key="4904755"

// From above, oceans appear beautiful, pristine and unchanging but beneath the surface are untold problems caused by man: dying fish, dangerous bacteria and huge dead zones. Pollution is the introduction of toxic waste into water bodies which then cause uneasiness and harm to the ecosystem. Pollution in the ocean affects ocean organisms directly and human health and resources indirectly. Since it is the world's major problem, we should work together to eradicate the problems which cause ocean pollution and eventually affecting the marine life .//

__ CAUSES OF MARINE POLLUTION __

//There are very many causes of marine life pollution but here are a just a few of them .//

__**OIL SPILLS ** __ 

//When oil spills, most of the explosive compounds evaporate quickly but the oil, however, remains floating on the surface of the water, and starts to dissolve, forming a very thin layer which can cover large areas of water. It blocks oxygen from reaching the surface of the ocean or sea and the animals suffocate due to lack of oxygen. Marine plants are covered in a coat of oil which prevents oxygen and water exchange, causing the plants to die due to suffocation. Aquatic animals which feed on this vegetation will in turn struggle to survive as they can not eat the vegetation as it is contaminated by toxic oil. Also when the oil sticks on feathers of birds especially the wing areas, their wings became sticky and they cannot fly and can develop hypothermia as a result of exposure to extreme cold and water. The oil also removes water resistant components from their coats of furred marine life such as seals. //

__FARM CHEMICALS __ // Farm chemicals are another cause of ocean pollution. These are substances that are used to make crops grow better in farms but they contain chemicals that are deadly to the aquatic animals and plants. When it rains the pesticides and fertilizers are washed from the plants and end up into the oceans and seas killing many ocean plants ans animals. Farm fertilizers also encourage the growth of Alga which reproduces and covers a large area of the sea and blocks the sun from penetrating into the surface and water plants cannot make food for themselves and some animals. // __** TOXIC WASTES ** __ // Toxic wastes are poisonous materials that are dumped into the ocean and cause harm to aquatic animals and plants and have a huge impact on our health. Toxic waste gets into seas and oceans by the leaking of landfills, dumps, mines, and farms. These toxic chemicals settle in the sea, and ultimately some of the fish eat these chemicals. Other fish eat the fish that ate the chemicals, and these fish, too, will eventually die because they putting toxic waste into their bodies
