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.

How does polyurethane affect our environment?

           Commonly known as PU, polyurethane is a polymer that is used to make cushions and mattresses. It is also used as enamel for paints. Though it provides us a comfortable night’s sleep without disturbances, it disturbs our environment. Sad, but true.

           PU cannot be recycled. Sometimes it is burned or simply dumped in landfills. Toxic substances like dioxins are released when PU is burned. You already know what this toxic chemical can do to us. Besides dioxins, other harmful substances like isocyanides and hydrogen cyanides are also produced.

          When PU degrades, it gives out chlorofluorocarbon (CFC) that depletes the ozone layer.

How safe are our feeding bottles?

           Most babies are fed using feeding bottles. A plastic called polycarbonate is used to make feeding bottles because it is strong, durable and heat resistant to an extent. It can be sterilized easily and would not soak up odours. When it was first introduced, it was commonly accepted as a suitable substitute for glass and ceramic. Polycarbonate is preferred for making the inner linings of food containers and reusable plastic bottles as well.

           Though polycarbonate is a preferred material, it is not essentially safe. A harmful substance known as bisphenol-A leaches out of the polymer and gets mixed with food. This chemical can cause health issues. It changes the level of oestrogen in our bodies.

How bad are polyethylene bags for us?

           Polyethylene bags have multiple applications in our daily life. Though we use polyethylene products at least five times a day, they are not entirely safe.

           Lead and cadmium are used as additives in polyethylene. These metals are toxic and are known to leach out.

           Lead affects the nervous system; it is capable of causing unconsciousness, heart attacks, respiratory diseases and even death.

           Cadmium affects the cells and tissues of the kidneys and causes inflammation. It can also lead to diabetes. If these metals leach into the soil, it will result in soil and groundwater contamination.
