Plastic Debris In The World

What is plastic ? Plastic is the general common term for a wide range of synthetic or semi-synthetic materials used in a huge, and drawing, range of applications. Everywhere you look you will find plastic. We use plastic to help make our live more easier clean. You will find plastics in every single thing in everywhere you look, you wear . The toys we play with, the televisions we watch, the computers we use and the CDs we listen to contain plastic. Plastic have two types of materials which is thermoplastics and thermosetting plastics. Thermoplastics can be heated up to form products and then if these end products are re-heated, the plastic will soften and melt again. In contrast, thermosetting plastics can be melted and formed, but once

In 1996, entanglement and ingestion of marine by marine organisms conducted statistic , showed that these phenomena had been known to effect individuals of at least 267 species worldwide. This included 86%of all sea turtles, 44% of all seabird species, 43% of all marine mammal species and considerable fish and crustacean species. For most of the species cared, significant number of individuals were affected (Plastic Debris in the World’s Oceans, 2006). An additional and potentially harmful aspect of marine debris is its likely impact on organisms living on the seabed. Plastic debris is often buoyant but it sooner or later may break down and settle on the seafloor. An accumulation of this debris on the seabed may affect the organisms present. For example, a research on marine organisms in Indonesia where there was a high concentration of marine debris on the seabed reported that the physical presence of the debris affected both the number and type of marine organisms that inhabited the area (Uneputty and Evans, 1997). Furthermore, marine debris on the seabed can prevent the gas exchange between overlying waters and the pore waters of the sediments, which is result in less oxygen in the sediments. This can disturb the organisms that live on the seafloor and potentially influence this

This is big issue to our world. How plastics can harm to environment is because material of plastic bag is non-biodegradable a decomposition of plastic takes about 400 years to destroy by itself. However, plastic can burned, will make problem but it will produce poisonous chemicals. One of the pollutants that results when paper, plastics and salt water driftwood are burned in a wood stove is dioxin, a highly toxic chemical that doesn't decay and which builds up in the tissues of animals and humans (The Wood Heat Organization Inc. 2014). According to a World Health Organization fact sheet, once dioxins have entered the environment or body, they are there to stay due to their unusual ability to dissolve in fats and to their rock-solid chemical stability. Plastic bags are made of various chemicals which are mainly toxic. That is certainly very harmful to the health and the environment. The chemicals used to make plastic bags are xylene, ethylene oxide and benzene. These are toxic chemicals that are sources of variety diseases as well as interference in humans. They do not only provide negative effects on the health of people and animals as well as to the air. These chemicals can pollute the air too which again harm the living organisms. They will not only affect humans and animals but also plants, water and
