Plastic pollution flowing into oceans to triple by 2040: study

By Joe Brock

SINGAPORE (Reuters) – The amount of plastic waste flowing into the ocean and killing marine life could triple in the next 20 years, unless companies and governments can drastically reduce plastic production, a new study published on Thursday said.

Single-use plastic consumption has increased during the coronavirus pandemic, according to the International Solid Waste Association, an NGO. Face masks and latex gloves are washing up daily on Asia’s remote beaches. Landfills worldwide are piled high with record amounts of takeaway food containers and online delivery packaging.

The new research, produced by scientists and industry experts for The Pew Charitable Trusts and SYSTEMIQ, offers solutions that could cut the projected volume of plastic entering the ocean by more than 80%.

The road map for stemming the runaway ocean plastic waste crisis is among the most detailed ever offered in a study.

If no action is taken, however, the amount of plastic going into the sea every year will rise from 11 million tonnes to 29 million tonnes, leaving a cumulative 600 million tonnes swilling in the ocean by 2040, the equivalent weight of 3 million blue whales, according to the study published in the journal Science.

“Plastic pollution is something that affects everyone. It isn’t a ‘your problem and not my problem’. It’s not one country’s problem. It’s everyone’s problem,” said Winnie Lau, senior manager at Pew and co-author of the study.

“It’s going to get worse if we don’t do anything.”

The strategy laid out in the report includes redirecting hundreds of billions of dollars in plastic production investment into alternative materials, recycling facilities and waste collection expansion in developing countries.

This would require a U-turn by the energy industry, which is rapidly building new chemical plants around the world to boost plastic output as its traditional fuel business is eroded by a rise in cleaner energy sources.

OIL AND SODA

The amount of plastic produced annually has been climbing fast since 1950, when global production totaled 2 million tonnes. In 2017, that number was 348 million tonnes, and is expected to double again by 2040, the study estimates.

Big plastic makers, including ExxonMobil, Dow and Chevron Phillips Chemical, have said they are committed to tackling plastic pollution, despite increasing production. The projects they fund focus on cleaning up waste.

The paper recommends, however, governments implement laws to discourage new plastic production and provide subsidies for reusable alternatives.

The plastic industry has lobbied against government bans on single-use plastic.

Some of the biggest buyers of plastic are consumer goods companies like Coca-Cola, PepsiCo, Nestle and Unilever. They have all made commitments to use a greater amount of recycled content in products in the future.

But current government and corporate commitments will only reduce the amount of plastic flowing into the ocean by 7 percent by 2040, the Pew and SYSTEMIQ study finds.

To cut the flow of ocean plastic by 80%, paper or compostable alternatives to single-use plastic would be needed and packaging should be redesigned to more than double the share of recyclable material, the study says.

Some criticized the study’s inclusion of incineration, chemical recycling and plastic-to-fuel plants as ways to dispose of waste, saying these methods involve the release of climate-warming carbon emissions while also helping to sustain plastic production.

Instead, “we would be putting more emphasis on the need for reduction and stemming production of plastics,” said Von Hernandez, global coordinator at Break Free From Plastic, an NGO.

“If industry were allowed to continue with their projections of growth up to 2050, which quadruples production during this time, most of the recommendations from this report will be meaningless.”

Ocean could provide over six times more food than it does today

LONDON (Thomson Reuters Foundation) – The ocean could provide over six times more food than it does now with better management and more technological innovation, scientists said on Tuesday, adding that boosting cultivation of bivalves like mussels and clams could be especially beneficial.

They estimated the oceans could provide more than two thirds of the animal protein that U.N. food experts predict will be needed to feed the world in future. Fish currently accounts for about a fifth of animal protein consumed by humans.

Cultivating food from the ocean generally has a lower impact on the climate than land-based agriculture, and is not limited by the same land and water constraints, the scientists said.

Food from the seas is also highly nutritious, containing essential vitamins, minerals and fatty acids, they said in a report to be released at a symposium on fisheries hosted by the U.N. Food and Agriculture Organization in Rome on Tuesday.

“The ocean has great, untapped potential to help feed the world in the coming decades, and this resource can be realised with a lower environmental footprint than many other food sources,” said lead author Christopher Costello.

“If we make rapid and far-reaching changes in the way we manage ocean-based industries while nurturing the health of its ecosystems, we can bolster our long-term food security and the livelihoods of millions of people.”

The report comes at a time of rising concern about over-fishing caused by a combination of factors including illegal fishing, fishing subsidies, the use of the wrong fishing gear and environmental degradation which is damaging nursery grounds.

With reforms, the scientists said the fishing industry could boost catches by 20% compared to today, and by up to 40% compared to projected future catches.

But they suggested the greatest potential gains lay in expanding the cultivation of bivalves like mussels, scallops and clams, which feed off organic matter in their environment.

This could also help improve water quality and create habitats for wild fisheries.

The scientists also called for more research into the potential of seaweed as a food source, especially as a replacement for fish-based ingredients in animal feed.

Studies suggest that certain seaweeds may reduce methane emissions from livestock which are a significant contributor to greenhouse gas emissions.

The report has been produced for an initiative spearheaded by 14 government heads called the High Level Panel for a Sustainable Ocean Economy, which aims to push the ocean to the top of global agendas.
