Plastic Pollution

1Since the first modern plastics were developed in the early twentieth century, global production has increased at a staggering rate. Today, the world produces more than four hundred million tonnes of plastic every year. Of this, only around nine percent is ever recycled. The rest is buried in landfill sites, burned or simply left to make its way into the natural environment. Plastic does not biodegrade. Instead, it slowly breaks into smaller and smaller fragments called microplastics, which can persist in the environment for hundreds of years.

2The oceans bear the heaviest burden. Scientists estimate that more than eight million tonnes of plastic enter the oceans every year. It accumulates in vast circular ocean currents called gyres, forming enormous patches of floating debris. The Great Pacific Garbage Patch, the most well-known of these, covers an area estimated to be twice the size of Texas. Marine animals are particularly at risk. Sea turtles mistake plastic bags for jellyfish. Seabirds feed plastic fragments to their chicks. Whales have been found dead with dozens of kilograms of plastic in their stomachs.

3The problem does not stop at the water's edge. Microplastics have been found in soil, in drinking water and even in the air we breathe. Researchers have discovered microplastic particles in human blood, in lung tissue and in the placenta of unborn babies. The full health consequences of this are not yet known, but scientists are increasingly concerned. What began as a convenience material has become something that is now, quite literally, inside all of us.

4Governments, businesses and individuals are responding in different ways. Many countries have introduced bans on single-use plastics such as bags, straws and disposable cutlery. Some companies are investing heavily in biodegradable alternatives made from plant materials. Beach clean-up initiatives run by volunteers remove tonnes of plastic from coastlines each year. However, critics argue that these efforts are not nearly enough when weighed against the sheer scale of production.

5The solution, most experts agree, requires changes at every level. Individuals can reduce their consumption of unnecessary plastic, choose reusable alternatives and recycle more carefully. Businesses must take responsibility for the materials they use in their packaging. Governments need to enforce stronger regulations and hold manufacturers accountable. Above all, the pace of action must match the urgency of the problem. The plastic we produce today will still be in the environment long after all of us are gone.
