Plastic pollution is a global problem that is growing exponentially due to both an increase in consumerism and an increase in the number of plastics used to manufacture the things we use on a daily basis. Many of these items are single-use items, which are used once and then tossed in the trash. But what happens to this plastic once the trash can gets emptied? It doesn’t simply disappear into thin air. It usually ends up in the environment in some manner or form, with a great deal of it eventually ending up in the ocean Arguably one of the most pressing environmental challenges that we are faced with today is marine plastic debris.
The two common sources marine debris originates from are:
- land-based, which includes litter from beach-goers, as well as debris that has either blown into the ocean or been washed in with stormwater runoff; and
- ocean-based, which includes garbage disposed at sea by ships and boats, as well as fishing debris, such as plastic strapping from bait boxes, discarded fishing line or nets, and derelict fishing gear.
While discarded fishing gear takes its toll on the marine environment by entangling marine life and destroying coral reefs, it only comprises an estimated 20% of all marine debris – a staggering 80% of all marine debris stems from land-based sources. This is not that surprising, considering that around 50% of all plastics are used to manufacture sing-use items which are discarded soon after they are first used.
How Can We Solve Plastic Pollution?
We need to tackle the problem of marine debris head on. It’s not just an issue for environmentally conscious, it is an issue that ultimately affects human health. Man is a top predator that feeds on a variety of ocean fish, shellfish, and other marine species. We face the same risks as the killer whale and polar bear. While any plastic or polystyrene pellets that may have been clogging the gut of the fish that is nicely presented on our dinner plate have been long removed, the toxic contaminants originating from that debris remain stored in the flesh we are about to eat. Food for thought indeed.
