How did we get to this point?

It’s no secret that Canada has the world’s worst record on air pollution.

According to the U.N. World Health Organization, Canada is one of only six countries in the world that are among the worst air polluters, and that ranking only goes up as pollution increases.

So why does Canada have such a bad reputation?

Well, pollution in Canada isn’t the worst of all places.

But it is definitely not the best.

“If we can’t get rid of the smoke that’s created by burning fossil fuels, we’re going to get worse at it,” said Bill Gates, who has been calling for a global climate change action plan since the 1970s.

But for Canada, the problem isn’t just a matter of climate change.

According, as many as half of the country’s oil-sands reserves are in the ground.

So if Canada could cut down on oil-fired power plants and instead get more carbon-neutral energy from renewable sources like wind, water and solar, it could solve many of the problems facing our nation.

As it stands, the government has said it is committed to reducing emissions by 40 per cent by 2020.

And according to a report by the federal auditor general released last year, Canada’s carbon-emissions targets are not sustainable.

In fact, Canada ranks last among all OECD countries in terms of the amount of greenhouse gas emissions it produces per capita, according to data from Environment Canada.

But even though it has a much bigger carbon footprint, Canada doesn’t have a comprehensive plan to cut it down.

“We’ve got to have a much more holistic approach to this issue,” said Ken Marshall, who was appointed Canada’s first environment minister in 2016 and is now a professor of economics at Dalhousie University.

“And the climate change agenda needs to be seen in the context of the environment and how we’re changing our economy, our transportation system, our infrastructure.”

He says Canada needs to invest in transportation and the environment in general.

“In the long run, you need to get away from fossil fuels and invest in a low-carbon economy.”

In fact that’s what Trudeau said during his campaign.

“You have to have the infrastructure in place to move people from the cities to the suburbs,” he said.

“It’s a question of how to do that and what the infrastructure is to do it.”

That infrastructure has been sorely lacking, and the government is still waiting for the results of the recent national climate change review.

The review found that Canada still has a long way to go to reduce emissions.

And despite Trudeau’s promises, there are still some things that need to be addressed.

For example, the federal government has yet to provide an overall plan to help communities that have suffered the effects of climate-induced droughts and flooding.

The province of British Columbia is also facing a severe water shortage, with some communities still without water for up to four weeks a year.

The country’s largest energy company, Enbridge, is also under federal investigation for not meeting its emissions targets.

And a number of other companies and industries are under investigation for failing to follow environmental rules and practices.

And in 2017, the U,S.

Supreme Court ruled that carbon pollution from the coal-fired electricity generation industry was an unconstitutional violation of the First Amendment, forcing the government to set an ambitious carbon-reduction target for 2020.

But that plan has been plagued by delays and the need to work with other nations to reach the targets, which have yet to be set.

So the future looks bleak for Canada’s air.

“I don’t know what’s going to happen,” said Marshall.

“The fact that the government hasn’t even come up with a plan to actually address this issue, and instead is going in this direction of trying to regulate this industry, it just doesn’t make sense.”
