Looking for birds and plastic in Denmark

Reflecting on my recent research trip to Copenhagen

People who love birds look for birds wherever they go. I happen to be one of those people.

When I recently took a trip to Denmark, early morning bird watching with my Alaskan malamute dog became one of the most pleasurable parts of my daily routine. We’d walk from our fifth-floor apartment in Copenhagen’s Nørrebro neighborhood down and around the three manmade lakes that run through the heart of the city. Because where there is water, one will often find birds.

And we did see birds, my dog and I. They belonged to an interesting array of species: hooded crows, Eurasian magpies, mute swans, mallards, pigeons, great blue herons, Eurasian coots, great cormorants, black-headed gulls, red-necked grebes….

Seeing so many birds in one small urban environment was heartening. But the birds’ habitat itself wasn’t always pretty. The lakes in Denmark — like many water bodies all over the world — are filled with plastic. Some of it is thrown there intentionally, while the rest blows in off roads and out of trashcans.

On more than one occasion I watched plastic bags — just out of my reach — blow across the water’s surface past the many birds that floated there. A lot of the bags, and other plastic trash — like water bottles, balloons and children’s toys — sank to the bottom of the lakes, right where many of the water birds dive and dabble. Research on plastic suggests bottom-feeding organisms are ingesting the stuff — so there’s little reason to believe the birds I’m seeing aren’t scooping some of it up.

There is a big political push now in Denmark to combat plastic pollution. SF, a left-wing political party just introduced a new bill that would help do that. Pro-environment nonprofits and non-governmental organizations such as the Danish Ecological Council are pushing for it to become law.
According to the Danish scientists I met with, one newly identified source of plastic pollution is plastic microfiber found in clothing. This microfiber can be found in wastewater sludge, which is used to fertilize crops — from which plastic is probably being washed off by rain back into the oceans and other water bodies. To limit this type of plastic pollution, scientists say plastic-free clothing as well as upgraded sewage and sewage treatment technologies are needed.

So, while plastic is now getting a lot of political attention in Denmark and other parts of the world, only our own actions can prevent pollution. And scientists say that means we need to use less or no plastic, and if we do use it we must take care to dispose of it properly or take measures to ensure it doesn’t end up in natural ecosystems.

Until we do these things, we can expect to see plastic collecting quite unnaturally amongst the birds and other wild creatures — where it should not be.
