Humans are fast becoming city dwellers. According to the United Nations, “The urban population of the world has grown rapidly from 746 million in 1950 to 3.9 billion in 2014.” Sixty-six per cent of us will likely live in urban environments by 2050. The number of mega-cities (more than 10 million inhabitants) is also skyrocketing, from 10 in 1990 to 28 in 2014 — home to more than 453 million people — and is expected to grow to 41 by 2030.

Alberta is home to two of Canada's imperilled caribou populations, the southern mountain and boreal woodland herds. Both are threatened with extinction.

Under the federal Species at Risk Act, the boreal woodland caribou recovery strategy requires provinces to develop range plans by 2017, outlining paths to recovery. Because caribou need large, intact areas, degraded habitat must be restored so industrial and natural disturbances affect no more than 35 per cent of each range.

Can we significantly reduce greenhouse gas emissions by switching to cleaner fuels? Or is this just an attempt to keep 20th century technology chugging along while trading one set of environmental problems for another?
