5 tips for trimming your culinary carbon footprint that don’t involve going vegan
Your supper last night may have generated as many greenhouse gas emissions as driving to the next town in your car. At best, it was probably the equivalent of a couple of kilometres.
The good news is that it’s quite easy to eat more sustainably. Science shows there are lots of ways to reduce your dietary carbon footprint without going vegan — or even giving up any foods you enjoy.
Bonus: They’ll probably save you money, too. MORE

More than two-thirds of Canada’s biodiversity is made up of species that occur within the country’s borders only at the very northern edge of their range. Biologists have long debated how much effort should be dedicated to conserving these ‘edge populations.’ One argument in their favor is that they may be especially well suited to lead northward range shifts for their species as the climate warms.

Blockchain is the technology the underpins digital currency and allows digital information to be distributed, but not copied. That means each individual piece of data can only have one owner.
2019 is looking like an exciting year for clean technology. Around the world, countries, cities and companies are embracing the shift toward sustainable energy — and figuring out how to turn a profit while doing it.
Look for announcements over the next year in the sectors of energy storage and microgrid systems that use artificial intelligence and blockchain. Conventional power stations are centralized and often require electric energy to be transmitted over long distances, to serve a large number of customers at once. Microgrid systems, on the other hand, are located much closer to the area they service, and can operate autonomously from the main power source.
Using smart technology, local demands can be customized, and grid disturbances like power outages can also be minimized. They can make a power grid greener, more cost efficient and more reliable. MORE
The big question now is whether businesses will push back and go down a cleaner path on their own. It’s easy to see why multinationals might as they face pressure from sub-national regions — California Gov. Jerry Brown held a Global Climate Action Summit which produced many aggressive climate goes from cities and state, for example.
Gov. Brown also signed aggressive new laws committing to carbon-free electricity statewide by 2045 and requiring solar on all new homes. So even if U.S. action sputters, governors and mayors who influence local and regional business conditions will be pushing the clean economy and pro-climate agendas. MORE

“What side of history do you want to be on?” Indigenous Alaskan Tonya Garnett asked the Department of Interior officials seated at the dais. “What legacy do you want to leave behind for your children?”
Garnett had journeyed from her small Gwich’in community of Venetie, Alaska, to speak on behalf of her people. “Our way of life is at stake,” she explained. “We speak for our ancestors, and we speak for our children’s children. I want to see my son — my 9-year-old son — be able to get his first caribou. I want to see his sons or his daughters get theirs.” MORE
