The Oceans : A Critical Part Of All Living Things Survival

Decent Essays

The oceans are a critical part of all living things survival. Earth is made up almost entirely by oceans, about 70% of the earth’s surface is covered in water. About 97% of all water on earth is contained in our oceans, and about half of all the air we breathe is provided by plants and organ-isms that live there (Laurence, 2010). Our oceans are key in providing home to small organisms creating the base of our food chain. Though marine habitats are being destroyed by a number of different factors which heavily effect the rest of the worlds ecosystems, closely monitoring these ecosystems and how they are being destroyed is important to preserve the biodiversity of the planet. There are many smaller ecosystems that make up our oceans, these include mangroves, the intertidal zone, coral reefs, and the open ocean. The ocean is always moving and changing, surface ocean currents move water from the deep ocean to more shallow areas bringing nutrients to the plants and animals that thrive there. Ocean currents also shape our coastlines and effect our weather patterns. Without a combination of all of these factors our planet would not be habitable (Laurance, 2010). Many of the small birds and mammals that make up the base of our food chain feed from small fish and crustaceans found in our oceans. Without them many other species would not have enough food and become extinct. Habitat destruction occurs when the conditions necessary for plants and animals to sur-vive are significantly
