What is the largest source of plastic pollution in our oceans?OPTIONS Straws Plastic bottles Fishing nets Microbeads

The world population is living, working, vacationing, increasingly conglomerating along the coasts, and standing on the front row of the greatest, most unprecedented, plastic waste tide ever faced. Washed out on our coasts in obvious and clearly visible form, the plastic pollution spectacle blatantly unveiling on our beaches is only the prelude of the greater story that unfolded further away in the world’s oceans, yet mostly originating from where we stand: the land. For more than 50 years, global production and consumption of plastics have continued to rise. An estimated 299 million tons of plastics were produced in 2013, representing a 4 percent increase over 2012, and confirming an upward trend over the past years. In 2008, our global plastic consumption worldwide has been estimated at 260 million tons, and, according to a 2012 report by Global Industry Analysts, plastic consumption is to reach 297.5 million tons by the end of 2015. Plastic is versatile, lightweight, flexible, moisture resistant, strong, and relatively inexpensive. Those are the attractive qualities that lead us, around the world, to such a voracious appetite and over-consumption of plastic goods. However, durable and very slow to degrade, plastic materials that are used in the production of so many products all, ultimately, become waste with staying power. Our tremendous attraction to plastic, coupled with an undeniable behavioural propensity of increasingly over-consuming, discarding, littering and thus polluting, has become a combination of lethal nature. A simple walk on any beach, anywhere, and the plastic waste spectacle is present. All over the world, the statistics are ever growing, staggeringly. Tons of plastic debris (which by definition are waste that can vary in size from large containers, fishing nets to microscopic plastic pellets or even particles) is discarded every year, everywhere, polluting lands, rivers, coasts, beaches, and oceans. Published in the journal Science in February 2015, a study conducted by a scientific working group at UC Santa Barbara’s National Center for Ecological Analysis and Synthesis (NCEAS), quantified the input of plastic waste from land into the ocean. The results: every year, 8 million metric tons of plastic end up in our oceans. It’s equivalent to five grocery bags filled with plastic for every foot of coastline in the world. In 2025, the annual input is estimated to be about twice greater, or 10 bags full of plastic per foot of coastline. So the cumulative input for 2025 would be nearly 20 times the 8 million metric tons estimate – 100 bags of plastic per foot of coastline in the world!Q.17 :-As per the passage, which of the following statements are true? Most of the plastic present in the ocean today has originated from the land and plastic pollution is present on almost every beach.Most of the plastic present in the ocean today has originated from the land. In recent years, the production of plastics has declined and plastic pollution is present on almost every beach.Plastic is cheaply available and that lead to the overconsumption and it  does not degrade easily thus it ended up being a pollutant. Most of the plastic present in the ocean today has originated from the land.In recent years, the production of plastics has declined. PreviousNext

Push to Recycle Ocean PlasticConsumer products giant Procter & Gamble (P&G) is tackling marine pollution by creating bottles madefrom beach plastic and developing new technologies to reduce waste. In recent years, the fight againstocean plastic pollution has gone from a pre-occupation of marine scientists to a movement embraced byeveryone from schoolchildren to Queen Elizabeth II, galvanized by images of trash-strewn seas and seaturtles choking on plastic straws and other consumer castaways. Many cities have moved to prohibitrestaurants from offering single-use plastic straws and other nonrecyclable items, a policy increasinglyadopted around the world (Woody, 2018).Big corporations clearly are getting the message. In December 2018, Dell, General Motors, and othercompanies formed the NextWave consortium with nonprofit Lonely Whale to build a supply chain tointercept ocean-bound plastic trash and turn it into everything from packaging and furniture to bicycleparts. P&G, Unilever, PepsiCo, Inc., and other Fortune 500 corporations are appearing at high-profileocean conferences to make commitments to reduce their plastic use and launch initiatives to recyclemarine plastic debris (Woody, 2018).In 2017, World Economic Forum in Davos, Switzerland, P&G unveiled a new bottle for its Head & Shouldersshampoo comprising up to 25 percent plastic collected from beaches. In addition, the company introduceda Fairy washing-up liquid soap bottle made with 10 percent beach plastic and 90 percent other recycledplastic. Virginie Helias, P&G’s vice president for global sustainability, stated, “When you think about it, it’skind of logical because when you go grocery shopping, the first thing that happens is you have a full binof unnecessary packaging that you throw away. So it’s the most tangible for people, that packaging isthere and it doesn’t go away, and also, they are paying for something that they don’t use” (Woody, 2018).Answer the following items: (3 items x 10 points)1. Identify and describe the activity/ies of backward logistics present in the given case.2. Expain the economic and organizational benefits that can be derived from recycling ocean plastics.3. Propose an effective supply chain measure that will help companies further reduce ocean plastics.

Plastic pollution is a consistent problem in the world's oceans. We can do our part to help by ___________ down the use of plastic bags and bottles, straws, and avoiding items with plastic packaging.

Propose ways that plastic pollution might decrease the biodiversity of a marine ecosystem.
