Plastic Pollution

Decent Essays

Plastic, a lightweight, tough and flexible material, first invented in 1907, and is constantly present in daily, modern life. Ironically, it was invented to save animals as it replaced materials such as ivory and whale bone. Plastic production isn’t slowing down - in 2012 there was a 4% increase in production of plastic from 2013 worldwide. In New Zealand, we use 1 billion shopping bags per year and around 60 kg on average of plastic per person per year! Astoundingly, only 5.58 kg on average of plastic per person is recycled. Plastic never goes away completely and it’s only increasingly going into oceans and onto beaches. Plastic can take up to 500 years or more to biodegrade. Plastics pollution in oceans has a direct and deadly …show more content…

NZ has limited recycling facilities, but plenty of collecting and sorting depots. Instead, NZ companies sort and grade items. Companies in Australia, China, Indonesia, India and Vietnam then tender for a shipment of a certain grade of paper, plastic or aluminium. Plastics that aren’t recycled (for e.g. plastic bags, takeaway coffee cups, plastic bottle lids etc.) end up in landfills which are problematic. When decomposing, organic waste makes methane, a greenhouse gas, and many chemically treated materials make leachates. Uncollected leachate can contaminate groundwater and soil. Methane is 25x more harmful to the environment than CO2. Plastic in landfills isn’t moving elsewhere and will continually expand, taking up more valuable space that people could use as living space instead. 190, 000 tonnes of plastic goes into landfills per year. Also, rain leaches out chemicals from the plastics which can enter soils and groundwater (leaching process). However, plastic isn’t the only problem in our oceans - oil usage is also. To make 1 kg of plastic, it takes 2 kg of oil (including the energy needed to make the plastic and as an ingredient). So, for every 2 kg of plastic made, 6 kg of CO2 is made. A gyro is the circular rotation of water within a basin that is driven by the wind. There are 5 ocean plastic gyros worldwide where ocean currents have swept plastics into a certain area and concentrated them. The largest is in the North Pacific a.k.a “The Great Pacific
