Plastic pollution is when plastic has gathered in an area and has begun to negatively impact the natural environment and create problems for plants, wildlife and even human population. Often this includes killing plant life and posing dangers to local animals. Plastic is an incredibly useful material, but it is also made from toxic compounds known to cause illness, and because it is meant for durability, it is not biodegradable. Plastics are everywhere, in our home, school, work, playground, parks, and beaches. It is such a popular material because it is flexible, lightweight, moisture resistant, and inexpensive. Even if plastics are found deep inland, they eventually find their way to the sea or ocean through rivers and streams. The global consumption of plastic was 260 million tons in 2008. It is estimated to reach 297.5 million tons by 2015. Bio-degradation is the natural break-down of organic substances. For example, dead plants and animals eventually decay. Plastic does not bio-degrade. Nature does not know how to break down plastic because of what plastic is made of. Photo-degradation is the break-up of materials by the sun. When something is photo-degraded, it does not change its composition the way it does if it were bio-degraded. The only thing that changes is its size. Plastic can photo-degrade. In large periods of time, plastics break down into very small pieces of plastic that float around. Plastic Pollution has many negative effects on the environment. We will discuss the impacts on birds, fish, turtles, coral reefs, human health, and on tourism and the livelihood of people. Causes of Plastic Pollution 1. Plain Old Trash Plastic is everywhere, even on those items you may not expect it to be. Milk cartons are lined with plastic, water bottles

Causes of Plastic Pollution

1. Plain Old TrashPlastic is everywhere, even on those items you may not expect it to be. Milk cartons are lined with plastic, water bottles are handed out everywhere, and some products may even contain tiny plastic beads. 2. Land PollutionWhen plastic is dumped in landfills, it interacts with water and form hazardous chemicals. 3. Air PollutionBurning of plastic in the open air, leads to environmental pollution due to the release of poisonous chemicals. The polluted air when inhaled by humans and animals affect their health and can cause respiratory problems.4. It is PoisonousMan artificially makes plastic by using a number of toxic chemicals.
