Why is Modbury important?

            Modbury was a not so famous village in England which came to the spotlight in 2007. It secured a place in history with a life-changing decision to ban plastic carry bags forever. Thanks to the efforts of Rebecca Hosking, Modbury is the world’s first ever plastic bag free zone.

           Rebecca screened her documentary Message in the Waves for the local shop owners of her hometown who were stunned to see the disastrous effect of plastic on marine environment. Crushed by the impact of the film, the shopkeepers decided to stop giving plastic bags. After a successful trial run for six months, plastic bags permanently disappeared from Modbury. They now use biodegradable cornstarch bags and reusable cotton, jute or paper bags.

What are the advantages of bioplastics?

            The production of bioplastics is eco-friendly, as they use renewable sources rather than the non-renewable sources, thus saving a lot of energy. They also make use of agricultural waste material. It produces less non-biodegradable waste than other plastics. It is therefore less contaminating.

            They do not change the scent or taste of the packed food. No harmful substance would leach out of bioplastics and they do not use additives that may affect health like phthalates and bisphenol-A. They give out less greenhouse gases as well. They are decomposable and cause no harm while blending with soil.

Do we have an eco-friendly alternative to plastics?

           It is ironic that the food items that last less than a week are packed using plastics that stay intact for centuries. Scientists had worked hard to find eco-friendly alternatives and by the 1990s, bioplastic was brought into the markets.

           Plastics are derived from non-renewable sources like petroleum or natural gas. Unlike them, bioplastics are made from renewable sources of biomass like bacteria, food waste, vegetable oils and corn starch. Bioplastics are mainly used for packaging and making disposable cutlery, straws and bowls.

Why is the documentary Albatross important?

           The documentary Albatross took shape in 2008 after a discussion between Chris Jordan and his friend Manuel Maqueda about the issue of ocean plastic pollution. They studied about young albatrosses dying of indigestion after eating plastic. They recorded what they witnessed in Midway Island in the north of the Pacific Ocean. They worked for more than four hundred hours and the footages were made into a film showcasing the plight of the species. The documentary was released in 2017.

           Albatross projected the devastating effect of plastic on marine ecosystems. It was found that nine in ten birds have traces of plastic debris in them. It helped in understanding the drawbacks of our lifestyle and the severity of the problem.

Are animals harmed by polymers?

           People in the south coast of Spain woke up to a huge dead sperm whale on a March morning in 2013. After careful examination, it was found out that the whale had died of severe indigestion. About 17 kilograms of plastic was found inside its body which had led to its death.

           This sperm whale is not the first animal to die because of our waste and it is not the last. Plastic poses a threat to the animals around us. Have you observed cows and buffaloes eating plastic from the garbage? These poor animals mistake plastic for food and end up eating it. This is known as food imitation; it leads to severe indigestion and they eventually die.

           Plastic has been found in the bellies of many types of fish and stray animals.

Is the packaging of Chips eco-friendly?

          Most of us love packaged chips. Let us now take a look at the journey of its packaging. These attractive packages are made of a kind of polypropylene known as BOPP.

          Lead and cadmium-based additives are used in the production of BOPP. This packaging material catches fire easily. To reduce its inflammability, some flame retardants are also used.

          The burning of this packaging material releases harmful substances like formaldehyde which is capable of causing respiratory diseases. Toxic substances are also released while this material is recycled. Workers in the recycling plants have often reported to suffer from health issues like headaches, asthma, skin and nasal irritation due to their exposure to harmful chemicals.
