Plastic in the environment presents a danger to animals in a number of ways.
First many animals eat plastic trash mistaking it for food or eating waste food from plastic bags. In March 2013 a sperm whale washed up on Spain’s South Coast was found to consumed 59 different plastic items including transparent sheeting used to build greenhouses in Almeria and Grenada, plastic bags, nine meters of rope, hosepipe, flower pots, and a plastic spray canister. Cause of death was intestinal blockage.
Turtles, fish and seabirds all eat plastic and suffer as a consequence.
Even if the plastic doesn’t kill outright, a diet of plastic has no nutritional value. Animals that eat plastic are found to be underdeveloped and underweight. “Dr. Jennifer Lavers found 270 pieces of plastic inside an 80 day old Flesh-footed shearwater chick last year. She’s also found that 100% of this species on Lord Howe Island contain plastic. Populations have already declined by more than 50% in the past 35 years. We need to find out more, before it’s too late.”
Micro bits of plastic may be killing the tiny creatures. Traditional plastics degrade rather than biodegrade, which means they simply break up and fall apart into smaller pieces. The plastic has not changed its structure as such – merely fragmented. These particles are called micro plastics and are being found in the oceans in ever-increasing quantities. Aquatic microorganisms such as plankton can also mistake micro plastic particles for food and subsequently be killed by the adverse effects of the particle on the organism’s digestive tract.
Then there are the as yet unknown consequences of eating plastic. Sea bourne plastic particles can both release chemicals (used in the manufacture of the product) and attract toxins. Research indicates that toxins such as persistent organic pollutants POPs (present in the sea water) stick to the plastic creating a toxic pellet. Marine animals eat these pellets. Researchers and scientists are becoming increasingly concerned that “this provides a feasible pathway to transfer attached pollutants and additive chemicals into their tissues” which will have a negative effect on the animals who consume them. This research on lugworms indicates that there are.
Persistent organic pollutants POPs are stored in the fatty tissues of animals and are passed on up through the food chain. They are bioaccumulate which has implications for the animals who consume the animals who consume the plastic! The chemicals absorbed by the plastic are transferred to the fish and possibly the consumer of the fish.
Plastic fishing nets are also extremely dangerous. Huge nets (between 75 feet to over 30 miles in length and sometimes several hundred meters deep) can and do get lost at sea. These ghost nets entangle animals who die of starvation. Modern synthetic (plastic) netting can sustain this cycle indefinitely while drifting over a vast range; ghost nets from around the Pacific have washed ashore on beaches as far apart as Alaska and the outer Hawaiian Islands.
