When is plastic pollution a problem in Canada?

Plastic pollution is a real problem in the Canadian economy, and the government is struggling to curb it.

But a new study suggests that the problem isn’t a new one.

The study by researchers from McMaster University and the University of Toronto, along with colleagues from the University at Buffalo, found that plastics pollution is on the rise, and not only in Canada, but also globally.

The research was published online in the Proceedings of the National Academy of Sciences.

“The plastics industry is the most important source of pollution in Canada,” said lead researcher James Loeffler.

“So we think there is an issue of concern in terms of how that impacts the economy and the people who use the environment.”

The researchers measured the pollution levels in plastic-filled lakes and rivers around Ontario and the Prairies, in cities in Canada’s two largest provinces.

They found that plastic pollution levels were up by over 10 percent in some areas.

But the increase wasn’t uniform, and was mostly concentrated in the cities of Toronto and Ottawa.

That makes the problem more complicated than the scientists initially thought.

“You can’t say that this is the end of plastic pollution,” said Loefler.

It’s not a new problem.

In 2011, researchers at the University toymakers P.L.P. and P.E.I. found that the plastic pollution in lakes in their province was higher than the pollution in other lakes.

This prompted the researchers to create a map showing where the most pollution is found, and how it affects aquatic life.

The researchers found that there were several lakes in the province that were at or above the highest levels of plastic waste.

In fact, they found that one lake, located about 20 kilometers (12 miles) south of Ottawa, was so polluted that it was the highest source of plastic pollutants.

The map showed that the pollution was concentrated in some parts of the province.

For example, the study found that about 80 percent of the pollution from plastic in Lake Champlain was in the northwestern portion of the lake, where it was concentrated near the water’s edge.

But in the western portion of Lake Chamoun, about 85 percent of plastic was in freshwater.

That meant that plastic was being carried by winds and currents that were pushing it out into the open ocean.

“This was the first study to show that plastic pollutants in the Great Lakes are moving out of the coastal area and into inland waters,” said the study’s lead author, Michael Schmader.

“That’s pretty surprising.

We thought the Great Lake watershed would be a good place to test the waters.”

And while there were still some lakes in Ontario that were above the maximum pollution levels, there were some areas that were closer to the average.

But this is a global problem.

While plastic pollution can be found in most areas, it is especially prevalent in Canada.

“In Canada, we’re at the highest risk,” said Schmacher.

“We’re also the only country where we have a clear, well-defined baseline for measuring plastic pollution.”

There are several theories about why this is happening.

The first is that the Great Sea’s currents and currents of all sizes and shapes can trap plastic pollutants and keep them there for a long time.

The second is that plastics are being processed in water, and are being mixed with water that is very acidic, which makes them more easily absorbed by the body.

But there’s also the idea that it’s just part of the natural processes that make up the water.

“It’s a little bit of both, but I think it’s the way it is,” said researcher Elizabeth Schmeder, from the U.S. National Oceanic and Atmospheric Administration.

“There’s a lot of stuff going on in the water that’s not being noticed, so there’s lots of opportunities to get these pollutants.”

In addition, plastic is used in packaging and other products.

The third possibility is that plastic is being used as a raw material, which means it’s being processed for use elsewhere.

And the fourth possibility is there is a connection between the environment and the plastics that are being produced.

“These contaminants are all released into the environment,” said John Wiegand, a researcher at the Woods Hole Oceanographic Institution.

“A lot of them are in the environment because the plastic that’s being made into these things is also being recycled into products.”

This has led to a lot more questions about what’s causing the increase in plastic pollution.

For one, the research doesn’t directly link the increase to plastics manufacturing.

Rather, the researchers used different methods to isolate plastic from the surrounding environment, including measuring the pH of water samples and comparing them to samples from the Great Water System.

“What’s interesting is that you see this difference in plastic concentration,” said Wiegall.

“At one point, there was a significant concentration in the bottom of the water column, and that indicates that it is an indicator of a chemical source, and it’s an indicator that plastic has been transported out of
