Radon is a radioactive gas formed by the natural decay of uranium in soil and rock. It can seep into buildings through foundation cracks and other openings. Without proper ventilation, radon concentrations in indoor air can reach dangerous levels. You can't see, smell or taste it, so it's easy to ignore. But radon exposure is the leading cause of lung cancer among non-smokers.

Canada's environment appears to be taking the brunt of NAFTA-enabled corporate attacks. And when NAFTA environmental-protection provisions do kick in, the government often rejects them. According to a study by the Canadian Centre for Policy Alternatives, more than 70 per cent of NAFTA claims since 2005 have been against Canada, with nine active cases totalling $6 billion outstanding.

Some see low fuel prices as good news, but there are many downsides. With driving becoming less costly, more cars and trucks could be on the road, which is good for the auto industry but bad in terms of pollution, climate change and traffic accidents. And because the price of oil is now lower than the cost to extract oilsands bitumen, the industry is starting to put the brakes on rapid expansion plans -- bad news for workers and businesses in Fort McMurray and those heavily invested in the industry but good news for the planet.

Mining is important to human well-being, but the current economic system means it's often aimed at maximizing profit with little regard for people or the environment. It's one area where Canadians can make a difference. Canadian mining companies haven't always had a great record for environmental and social responsibility in communities where they operate -- but public scrutiny and pressure may be helping to change that.

Once lauded for policies such as the carbon tax and energy agreements with California, B.C.'s political leaders have now embraced liquefied natural gas, claiming industry expansion will create hundreds of thousands of jobs and add billions of dollars to provincial coffers -- never mind that no one in power now will be held accountable for these promises because they're several elections from being realized.

I recently travelled across Canada with David Suzuki Foundation staff, from St. John's to Victoria and up to Yellowknife, joined by friends and allies along the way. To resolve the serious environmental issues we face in Canada and beyond, we need people from across the country and all walks of life to join together to make protecting the people and places we love a priority.

Wind power doesn't create pollution or global warming emissions. It's affordable and will never run out. Improvements to power-generation capacity, efficiency and affordability will continue to boost its importance in the energy mix.

Canada's newest "national park" is a vibrant patchwork of green space meandering through dynamic downtown neighbourhoods in one of Canada's densest metropolises, along the former path of a creek buried more than 100 years. It's a welcoming space for birds and bees that's nurturing a new generation of city-builders. And it may spread to your city.

While Winnipeg residents enjoy clean water, the people of Shoal Lake 40 suffer from substandard water. It's an abrogation of the basic right of all Canadians to have access to clean, safe drinking water. The fact that such deplorable conditions persist in places like Shoal Lake, and in hundreds of other First Nations, Metis and Inuit communities across Canada, is a national shame and must be resolved immediately.

Smartphones, the Internet and accessible research technologies deinstitutionalize science and get the inner scientist in all of us outside to contribute to a broader understanding of a variety of topics, from backyard birds to flower-blooming times. Science relies on observation. As more people examine natural phenomena and record and share information, we gain better understanding of the world. An increasing number of scientific inquiries now depend on contributions from ordinary people to help them answer important questions.

It's become a cliché to say that out of crisis comes opportunity. But there's no denying that when faced with crises, we have choices. The opportunity depends on what we decide to do. What choices will we make when confronted with the fact that 2014 will likely be the hottest year on record? Will politicians close their eyes while fossil fuel industry executives shovel money at them and enlist propagandists to spread misinformation and lies?

The idea of a right to a healthy environment is getting traction at Canada's highest political levels. Federal Opposition MP Linda Duncan recently introduced "An Act to Establish a Canadian Environmental Bill of Rights" in Parliament. If it's passed, our federal government will have a legal duty to protect Canadians' right to live in a healthy environment.

Have you heard of flupyradifurone? Probably not, unless you work for the federal government agency poised to approve this new pesticide for use in Canada. But take note: This new "F" word is bad news for bees.

Although extraction, use and export of natural resources are economically important and will remain so for some time, we're starting to diversify. According to Ottawa-based consultants Analytica Advisors, clean technology, or clean-tech, is the country's fastest-growing industry. The firm's "2014 Canadian Clean Technology Report," found direct employment by clean-tech companies rose six per cent from 2011 to 2012, from 38,800 people to 41,000, with revenues increasing nine per cent to $11.3-billion.

Sadly, the inability of governments to deal with climate change is neither just national, nor recent. We've been saddled with government indolence on climate and pollution for far too long, and in far too many places around the world. But Canada has been singled out for getting in the way of progress at global climate negotiations, and we're the only country to have pulled out of the legally binding Kyoto Protocol.

We've become impatient. We're so demanding that we're unwilling to slow down and ensure our major projects are sustainable for human society and the biosphere. Over the past century, we've burned increasing amounts of finite fossil fuels that were stored and compressed over millions of years, exacerbating conditions that lead to climate chaos.

At an estimated $7.9 billion and growing, the proposed Site C Dam on the beautiful Peace River in northeastern B.C. has been criticized. If built, Site C would violate First Nations' rights under Treaty 8, rendering them irrelevant to the point of mockery. How long will Treaty 8 First Nations be able to sustain a vibrant, living culture when the dam devastates their land and communities?

So how do we ensure that all Canadians have the right to enjoy clean air and water and healthy food? We could follow the lead of more than half the world's nations and enshrine the right to a healthy environment in our Constitution's Charter of Rights and Freedoms. That's one of the goals of the Blue Dot Tour

Despite all the benefits for students and educators, moving classes outdoors can be daunting. Teachers cite a host of barriers, from parental concerns to lack of time, confidence and support from administration. So how can a teacher ease in (or jump right in) to teaching outside?

Reducing the threat of global warming and finding ways to adapt to unavoidable change will also help people around the world "deal with the impact of heat, extreme weather, infectious disease and food insecurity." Climate change affects human health in multiple ways.
