According to a new research paper published
in 'Science Advances', 9.1 billion metric tons of plastic have been produced
since 1950. That represents one ton of plastic for every living person on the
planet, with nearly 7 billion of these tons no longer in use. While 9% of
plastic is recycled and 12% is incinerated, that still leaves 5.5 billion tons
of plastic to waste away on the land and in the water. “At the current rate, we
are really heading toward a plastic planet. It is something we need to pay
attention to.” says Roland Geyer, lead author of the study and industrial
ecologist at the University of California.
The use of plastics boomed after World War
II and has been growing ever since. Plastic production has outgrown all other
man-made materials other than steel and cement, which exist for longer in
buildings and cars and degrade much better than plastic. Roughly 35% of all
plastics are made for packaging according to the study, including those woven
into fibres such as polyester and microfibre materials. If you weighed all the
plastics that have been produced over the last 67 years, they would be as heavy
as 25,000 empire state buildings, 80 million blue whales, or 1 billion elephants.
Our use of plastic continues to accelerate
at an astonishing pace, with half of all plastics produced in the last 13 years
and 34 billion tons projected by 2050. “The growth is astonishing and it
doesn’t look like it’s slowing down soon." said Geyer, with the world
creating 448 million tons of plastic in 2015 alone - more than double the
number produced in 1998. China produces the most plastic, followed by Europe
and North America, with much of the stuff finding its way into our oceans. You
can't even escape plastic on a remote island, with Henderson Island in the
South Pacific covered by 18 tons of plastic – the highest density of
anthropogenic debris recorded anywhere in the world.
There's a lot of work to do if we want to
avoid becoming more of a plastic planet than we already are. While it's
unrealistic to stop using the stuff altogether, we should be putting much more
energy into finding and utilising alternatives for packaging and consumer
goods. Banning single-use plastic bags is an important part of the solution,
with an intensification of waste reduction and recycling schemes also needed.
There is no easy solution, however, with glass, paper, and aluminium packaging
often requiring more energy to produce in the first place. According to Steve Russell,
vice president of plastics for the American Chemistry Council, “Plastics are
used because they are efficient, they are cost effective and they do their
jobs... And if we didn’t have them, the impact on the environment would be worse.”
