overuse our ocean resources? It is possible to overuse our ocean resources. We can drill and use an excessive amount of oil from the bottom of the ocean. This resource is made up of dead fish and other creatures that sink to the ocean floor and as sediment builds up the dead animal remains decompose and heat up to form the oil and natural gas. This can take up to thousands of years to form and if humans use too much oil we will have to wait another thousand years to use the oil the ocean provides

Plastics have been around for a long time now. It has been said that even before Alexander Parke’s major pioneering contribution to the development of plastics from cellulose nitrate in the 1850’s‚ plastic like materials have been in use by mankind for centuries. Now life without plastic cannot even be imagined. Almost every piece we use day to day is either a plastic or has plastic components in it. Because plastics can be made into products of different strengths and flexibility we can find plastic

A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural.[1] A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable.

Why do I do it? Why do I scare myself with the ocean…? It is true‚ it is merciless‚ literally; it’s not conscious‚ so it has no feelings‚ no remorse‚ no pity‚ no awareness. It would be wrong to say it is inanimate‚ because it is certainly animate. And not alive‚ yet contains so much life within it might as well be. Like a Frankenstein body filled with cells and bacteria and nerve impulses yet no consciousness. My worst nightmare – I don’t have it very often but it’s a strong one – can take

Hossain Descriptive Essay July 2‚ 2013 The Ocean The ocean‚ from the Pacific to the Atlantic and the Indian to the Artic‚ is a vast and enchanting part of our world. The oceans of this world cover more than sixty six percent and that number is steadily rising. There are so many facets of the ocean that are yet to be discovered‚ but as someone who lives fifteen minutes away from a beach‚ it is hard not to be intoxicated by the allure that the ocean draws. Oceans have their own smell‚ feel‚ taste and sound

recycling of plastics bringing any long-term benefits to the environment? Plastics are one of the most popular building materials of modern human culture‚ but its widespread has brought many problems and caused environmental issues of extraordinary scale. Throughout the years‚ discarded plastics are accumulating as debris in landfills and in natural habitats worldwide. To control this issue‚ governments of many countries have established industrial processes for transforming discarded plastic into useful
