Friday, May 18, 2018 Picking up litter: Pointless exercise or powerful tool in the battle to beat plastic pollution?

Armed with bags, gloves, litter pickers and a strong sense of purpose, around 12,000 men, women and children got to work cleaning Britain’s streets, green spaces and beaches as part of a nationwide Great Plastic Pick Up during a weekend in early May.

Armed with bags, gloves, litter pickers and a strong sense of purpose, around 12,000 men, women and children got to work cleaning Britain’s streets, green spaces and beaches as part of a nationwide Great Plastic Pick Up during a weekend in early May.

The volunteers included young scouts, book club members, martial arts enthusiasts, politicians and celebrities - all giving their time to clear rubbish and raise awareness as part of the three-day campaign organized by the Daily Mail newspaper and environmental charity Keep Britain Tidy.

Prime Minister Theresa May, whose government has pledged to eliminate all avoidable plastic waste by 2042, took part at a school in Maidenhead and praised the volunteers for creating a “better environment for us all to share.”

Although nobody could doubt the selfless dedication of the thousands who took part, some activists argue that such volunteer clean-ups are not the best way to tackle the plastic pollution that is choking rivers, destroying once-beautiful beaches and costing the lives of whales, seabirds and other wildlife.

Critics argue that public cleanups do not address the root causes of this pollution. Cleaning a beach is not turning the tide, they say, because the tide will just come in again, depositing more plastic cups, bottles, straws, bags and discarded fishing equipment. What we need to do, they argue, is reduce unnecessary plastic at source, design less harmful products and develop better recycling processes.

David Katz, the founder and CEO of The Plastic Bank, which monetizes plastic waste by turning it into a currency that helps some of the world’s poorest people, likens the problem to an overflowing sink: there is no point in mopping the floor until you turn off the tap.

However, there is compelling evidence that cleanup campaigns, like the Great Plastic Pick Up, do make a difference and not just in the short term.

Every piece of trash that is taken away to be recycled or deposited in a landfill means there is one less dangerous item for birds, turtles or whales to swallow. Cleanups also restore these creatures’ habitats.

One need look no further than Versova beach in Mumbai. In 2015, lawyer Afroz Shah decided he had to act after moving into an apartment overlooking the beach and realizing the extent of the plastic pollution. He started picking up the rubbish with a friend and since then his weekend cleans have attracted scores of volunteers who have removed around 13 million kgs of waste in what the UN has called “the world’s largest beach cleanup project”.

In March, it was payback time after all the back-breaking, filthy work. Volunteers spotted around 80 olive ridley turtle hatchlings heading towards the sea. The vulnerable turtles had not been seen on the beach for decades. Volunteers slept by the nests to protect them from predators and made sure the baby turtles could make their way safely to the sea.

Beach cleanups also serve to educate. When volunteers see just how much plastic is deposited on our shores, they are often inspired to reduce their reliance on single-use plastics, and, crucially, to spread the word to others.

Tiza Mafira, lawyer and director of the non-profit Indonesia Plastic Bag Diet Movement, says beach cleanups give volunteers a clear sense of the scale of the problem.

“That alone can be a shock treatment but it needs to be accompanied with an educational or follow-up action. Otherwise, the shock treatment alone may leave volunteers feeling helpless,” she says.

“When we do beach or river clean-ups we always make sure that volunteers carry a non-plastic sack to contain the waste and we provide them with lunch wrapped in banana leaf and remind them to bring tumblers to show there are alternatives to plastic … There are also a number of ways you can sort and measure the waste afterwards, by type or by brand. This empowers volunteers to tell the government or call out specific industry brands that use these plastic packagings … Hopefully, this provides lasting behavioural changes,” she adds.

Professor Richard Thompson, professor of marine biology at the University of Plymouth, says that although beach cleans are not the sole answer to the plastic problem, he is in favour of them.

“My experience is that new volunteers join beach cleans all the time. This is important because they help to raise awareness more broadly. Our research at the University of Plymouth has shown volunteers also get a rewarding experience from helping to take positive action,” he says.

As Mafira notes, cleanup campaigns sometimes collect data on the litter found to determine where it comes from and thus aid longer-term efforts to cut down on marine plastic pollution. For example, the British Science Association and The Plastic Tide charity have asked the public to help chart plastic pollution by tagging items captured by drone technology and aerial photos taken of Britain’s shores. They hope to get more than 250,000 images tagged to build a tool that can measure how much marine litter there is and where it comes from.

There are also economic benefits to public cleanups. If beaches are covered with litter, tourists will not come. Last November, the Indonesian island of Bali declared a “garbage emergency”across a six-kilometer stretch of coast, with authorities forced to deploy cleaners and trucks to take around 100 tons of waste every day to a nearby landfill.

Indonesia, which is the world’s second-biggest source of marine pollution after China, has signed up to the UN’s Clean Seas campaign and pledged to reduce marine plastic waste by 70 per cent by 2025. It plans to curb the use of plastic bags, boost recycling services and launch cleanup campaigns.

Some islanders are already hard at work. In February, One Island One Voice, an umbrella group that organizes regular beach clean-ups, got more than 20,000 people to tackle the rubbish on 120 beaches around Bali.

Even if there is merit to the argument that the tap needs to be turned off before mopping the floor, there can be no denying the fact that volunteer cleanups protect wildlife, create momentum, raise awareness and save threatened habitats. It is nonetheless critical to make sure one seeks a long-term cure even while dealing with the symptoms of this toxic pollution.

“If I were advising a wealthy investor on where to place their money in order to have maximum effect, I would say invest 95 per cent in ways to prevent plastic litter from entering the oceans. Otherwise, we will be cleaning up forever, as will our children and our children’s children,” Professor Thompson says.

Plastic pollution of our rivers and seas is a monumental, multifaceted problem with global consequences. There is no silver bullet and no single activity can turn back the clock. However, public engagement appears critical to encourage behaviour change and increase pressure on governments and businesses to take action.

As with all the existential environmental challenges we face today, everyone has a role to play if the tide is to be definitively turned. You might not have a science degree, or a role in government, but we can all pick up the rubbish that is lying right in front of us. It is not the only solution, but it is a critical component of the complex solution required for this complex problem.

World Environment Day on June 5 offers a perfect opportunity to get involved in this fight to turn back the toxic plastic tide. UN Environment and its partners, including WWF, Plastic Free July and Let’s Do It World, are calling on people across the globe to step up and join the battle by cleaning their rivers, beaches, forests and towns.

Already hundreds of events -- from beach cleans in Sri Lanka to plogging in Canada and a dive against debris in Rio de Janeiro -- have been registered. You can check out what’s going on here, join an event or set up your own clean-up challenge to #BeatPlasticPollution.

#BeatPlasticPollution is the theme of World Environment Day 2018.
