Calculating farming's contribution to greenhouse gas emissions is difficult, but experts agree that feeding the world's people has tremendous climate and environmental impacts. Estimates of global emissions from farms range widely. The U.S. Environmental Protection Agency puts them at 24 per cent, including deforestation, making agriculture the second-largest emitter after heat and electricity.

Will vegans save the world? Reading comments under climate change articles or watching the film Cowspiracy make it seem they’re the only ones who can. Cowspiracy boldly claims veganism is “the only way to sustainably and ethically live on this planet.” But, as with most issues, it’s complicated.

The digital revolution is breaking new ground every day. Technology has a way of doing that. I remember when Hewlett-Packard introduced its first "laptop" computer, which stored a page and a half of writing. It revolutionized my life as a newspaper columnist, allowing me to write on planes or in a tent and submit articles through a phone. I never imagined the steady advances that would lead to today's powerful laptops, tablets and handheld computers.

Once while filming in a remote B.C. forest, I wanted to pan from the roots of a cedar tree along the trunk to the top in a single shot. After spending hours rigging wires and pulleys and struggling to keep the heavy camera from swaying as it rose, our crew gave up in frustration. Recently, we used a light GoPro camera mounted under a drone to get a spectacular high-definition shot in a few minutes!

If people keep rapidly extracting and burning fossil fuels, there’s no hope of meeting the 2015 Paris Agreement climate change commitments. To ensure a healthy, hopeful future for humanity, governments must stick to their pledge to limit global warming to 1.5 or 2 C above pre-industrial levels by 2050. Many experts agree that to meet that goal, up to 80 per cent of oil, coal and gas reserves must stay in the ground. That makes fossil fuels a bad investment — what analysts call “stranded assets”.

Putting money toward things that benefit humanity, whether investing in clean energy portfolios or implementing energy-saving measures in your home or business, is better for the planet and the bottom line than sinking it into outdated industries that endanger humanity.

Imagine if scientists came up with an inexpensive, easily administered way to decrease the risk of cancer, diabetes, heart disease, stroke and obesity by 25 to 35 per cent. It would create a sensation and, if patented, would be worth billions. But there’s already a free and simple way to achieve this: exercise.
