THIS POST IS A CRITICAL REVIEW OF AN ONLINE ARTICLE BY “PREVENTING OCEAN PLASTICS” ON THE OCEAN PLASTICS PROBLEM: LINK: https://www.pewtrusts.org/en/research-and-analysis/articles/2020/02/25/to-solve-the-ocean-plastics-problem-the-world-needs-a-plan

PART-1: WHAT THE “PREVENTING OCEAN PLASTICS” ARTICLE SAYS
Plastic pollution is also taking a toll on people and society. According to a report from the United Nations Environment Programme, the estimated cost of ocean plastic pollution on fishing, tourism, and shipping is at least $13 billion annually. And experts do not yet fully understand how all of this pollution is affecting—or will affect—human health. Of the 8.3 billion metric tons of plastic ever produced, approximately only 9 percent has been recycled and an estimated 60 percent has been discarded, with some ending up polluting our rivers and the ocean. The amount of plastic entering the ocean is projected to double in the next five years. The enormity of this problem has led The Pew Charitable Trusts to undertake a two-year initiative to identify the most effective strategies to address the marine plastic problem. Working with the global consulting firm SYSTEMIQ, we are conducting a global analysis that will quantify the ocean plastic pollution between 2016 and 2040 under different scenarios. We are also engaging with Duke University on a global plastics policy analysis that considers the responses to this issue by a range of governments around the world. Separately, Pew is working with a broad range of stakeholders to develop an evidence-based global roadmap for reducing marine plastic pollution. We expect to release that roadmap in mid-2020.
PART-2: CRITICAL COMMENTARY
In related posts we present the case that although the piles of trash on beaches seem rather large to our visionary judgement, the ocean is relatively large and in that context and when the size of the ocean is included in the analysis, the assumed pollution problem does not appear to be as serious an issue as the visual judgement may imply.
For example, we show in related post#1 linked below that even if {Every minute, the equivalent of one garbage truck of plastic waste enters the oceans} {as claimed by ocean pollution activists}, the amount of plastic going into the ocean is 8,000,000 tonnes per year if every minute of the day and night there is a garbage truck of plastic waste going into the ocean.
This may seem like a huge amount of trash and it may lead to conclusions such as {By 2050, there will be more plastic than fish in the world’s oceans}. Yet, the weight of fish in the ocean is 2E9 tonnes and at 8 million tonnes per year it will take us 2E9/8E6 years or 250 years to break even with the fish without consideration of “the missing plastic” issue in plastic pollution research described in related post #1. Briefly, the missing plastic issue in ocean pollution research is that 99% of the plastic dumped into the ocean simply disappears and can’t be accounted for in the ocean pollution data. Therefore, it will take us 250 years to break even with the fish if we don’t take the missing plastic issue into consideration and 25,000 years to break even wth the fish if we do take the missing plastic issue into consideration.
Another way to judge the scale of the ocean pollution issue is the weight of plastic we dump into it as a fraction of the water in the ocean. The weight of the water in the ocean is 1.4E18 tonnes. This rather large number implies that 1% of the ocean weighs 1.4E16 tonnes; and that means that at 8E6 tonnes per year it will take us 1,750 million years of continuous dumping at one garbage truckload per minute every minute of the day and night to get the amount of plastic pollution in the ocean up to 1% of the ocean by weight without consideration of the missing plastic issue. If the missing plastic issue is taken into considration, it will take us 175 billion years of continuous plastic dumping at one garbage truckload per minute every minute of the day and night to reach the goal where 1% of the ocean by weight is plastic.
HUMANS HAVE OVERESTIMATED THEMSELVES. THERE IS NO ANTHROPOCENE BECAUSE THE ANTHROS AND ALL THEIR ANTHROPOGENIC ACTIVITIES ARE INSIGNIFICANT ON A PLANETARY SCALE.
IN TERMS OF TOTAL WEIGHT THERE ARE 4 TIMES AS MUCH FISH IN THE WORLD AS HUMANS. FOR THE WEIGHT OF ALL THE HUMANS ON EARTH TO REACH 1% OF THE WEIGHT OF THE OCEAN OUR POPULATION WOULD HAVE TO MULTIPLY BY A FACTOR OF 200,000 AND POLAR KRILL SWARMS ARE TYPICALLY 500 MILLION TONNES IN WEIGHT. THE WEIGHT OF 7.8 BILLION HUMANS WITH AN AVERAGE WEIGHT OF 62KG IS 483 MILLION TONNES, LESS THAN A SINGLE SWARM OF POLAR KRILL. OUR ILLUSORY AND EXAGGERATED SELF IMAGE LIKELY DERIVES FROM THE BIBLE WHERE GOD HAD GIVEN MAN DOMINION OVER NATURE. THE REALITY IS VERY DIFFERENT. WE DON’T EVEN HAVE DOMINION OVER THE MONKEYS.

The shoreline waste problem could be alleviated in part if Asian nations didn’t dump lorry loads of plastic into rivers and seas. I sadly didn’t save two videos, one showing pickup trucks queuing to tip their loads into a river and the other showing a literal river of plastic waste flowing down a street after a downpour, in Indonesia as I remember.

Good point. The shoreline ugliness is not only an eyesore but it stinks and also attracts huge numbers of flies and other such creatures. I was one of the volunteers that cleaned up that pile at the chaam beach a few years ago and then they built a beautiful lookout platform where they now hold the evening aerobics event. What a complete transformation. Thank you for this very insightful comment.
