Plastic Pollution

Between 4.8 million tonnes and 12.7 million tonnes of plastic waste enter the ocean every year, 80 percent of it from land sources due to inadequate waste management. Plastic pollution is everywhere; even a tiny uninhabited island in the Pacific Ocean far from human contact had 18 tonnes of plastic washed up on it. Plastic waste was found at 36,000 feet in depth – the deepest spot in the ocean in the Mariana trench,

Joachim Spangenberg of Germany’s Helmholtz Centre for Environment Research called the “political economy” of pollution, where vested-interest lobbies profit by externalizing costs of production and discharging unwanted waste into the environment. 

 Anti-plastic campaigners are up against a global plastic industry worth 654 billion dollars by 2020. Dow Chemicals, Du Pont, BASF, ExxonMobil, and Bayer are key players invested in the sector. According to the Worldwatch Institute, plastic production is increasing 4-5 percent annually.

Certain countries have banned microplastics, some have banned plastic bags. Kenya, Rwanda and Bangladesh, for example, are recognised global leaders on plastic pollution.

Plastic aside, land-based sources pump in the maximum waste and pollutants into oceans and coastal waters, mostly through rivers. Farming, food and agro-industry, fisheries and aquaculture, oil and energy sector, waste, wastewater, packaging sector, extractives and pharmaceuticals are major sources.

In coastal regions where 37 percent of the global population lives, these pollutants can stunt neurological development, cause heart and kidney disease, cancer, sterility and hormonal disruption.
Among the little know impacts on marine creatures, ingestion of microplastics (size less than 5 mm) by fish can affect female fertility and grow reproductive tissue in male fish causing their feminization. Chemicals in plastic cause thyroid disorder in whales, physiological stress, liver cancer, and endocrine dysfunction, says UNEP’s 2017 pollution report.
"If action is not taken today, we’re lining ourselves up for the ultimate cost – the destruction of our oceans – down the line." Erik Solheim, head of UN Environment, explained.
