Half measures aren’t enough to save caribou

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.

Will growing our fuels drive us to a cleaner future?

The shift from fossil fuels to renewable energy is occurring mainly at the power plant level. But what about transportation? 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?

The Future of Hydro in a Warming World

People have harnessed energy from moving water for thousands of years. Greeks used various types of water wheels to grind grain in mills more than 2,000 years ago. In the late 1800s, people figured out how to harness the power to produce electricity. Throughout the 20th century and into the 21st, hydropower has expanded, producing about 17 per cent of the world’s electricity by 2014 and about 85 per cent of renewable energy — and it shows no signs of slowing.

Dark earth could herald a bright future for agriculture and climate

Over the past half century, the world has moved increasingly to industrial agriculture — attempting to maximize efficiency through massive, often inhumane livestock operations; turning huge swaths of land over to monocrops requiring liberal use of fertilizers, pesticides and genetic modification; and reliance on fossil fuel-consuming machinery and underpaid migrant workers. This has contributed to increased greenhouse gas emissions; loss of forests and wetlands that prevent climate change by storing carbon; pollution from runoff and pesticides; antibiotic and pesticide resistance; reduced biodiversity; and soil degradation, erosion and loss.

South Australia sets an example for the country and the world

First-time visitors to Australia are often drawn to the big city attractions of Sydney and Melbourne or the fabulous beaches of Queensland’s Gold Coast. I’ve always had a soft spot for Adelaide in South Australia, a city built more on a human scale, where downtown can be easily navigated on bike, foot or tram. For me, Adelaide’s greatest attraction is a huge market right in the city’s center.

Feed-in tariffs help renewable energy grow

In the early 1990s, Germany launched Energiewende, or “energy revolution,” a program “to combat climate change, avoid nuclear risks, improve energy security, and guarantee competitiveness and growth.” Renewable energy grew from four per cent in 1990 to more than 27 per cent in 2014, including a significant increase in citizen-owned power projects, according to energy think tank Agora Energiewende.

Oceans of reasons to protect what we love

June 8 marks World Oceans Day, but what if we celebrated oceans every day? Covering more than 70 per cent of Earth’s surface, oceans, more than anything, define our small blue planet. We should celebrate their complex and vibrant ecosystems, life-sustaining services, calming effects and unimaginable diversity, much of which we have not yet even discovered.
