Urban sprawl has spread to the sea, as more and more man-made structures are being built along the world’s coastlines. Just as we do on land, we need to think about how to build sustainably at sea.
Remote Indigenous communities aren’t just places to live - they are also crucial for supporting ranger programs and other projects that protect the environment in areas that might otherwise go untended.
Incentives for cutting peak power demand are cheaper than building ever more infrastructure and sending power bills ever higher. The industry has a chance to embrace this new approach - but will it?
Proposals to reintroduce Tassie devils to the Australian mainland have argued devils could help control feral cats. But new research shows there’s no simple answer.
The 2015 Intergenerational Report underestimated the threat of climate change. An open letter from environmental and climate scientists.
Ahead of meetings at the end of this year in Paris, countries will submit draft contributions for a global climate deal. The goal: reducing greenhouse gases beyond 2020, and ultimately keeping global warming below 2C.
When their populations explode, killing koalas is sometimes the only way to reduce their suffering. But why do some places have too many koalas?
A new report shows Australia can and should double its energy productivity, increasing economic productivity while reducing greenhouse gas emissions.
The Perth Canyon, off Australia’s west coast, is twice the size of the Grand Canyon. But only now, with the help of remote-controlled submarines, are researchers finding out what lives in its depths.
The G20 has pledged to spend more than US$60 trillion on new infrastructure in the next 15 years, much of which will affect pristine areas. Without a solid plan, the environmental toll could be huge.
Meat uses a lot of resources - between three and ten times as much as plants for the same amount of protein. The rich world might be slowly losing its taste for meat, but the developing world isn’t.
We have hit a new milestone in carbon dioxide levels: the average for February topped 400ppm. It’s the first time this has happened in the northern winter, when levels are typically lower than in summer.
Is it worth trying to put a price on the natural world, when things like water and food are priceless? Yes, says Paul Sutton - without knowing the value of the environment, we might not value it at all.
Climate change barely rates a mention in the Intergenerational Report, despite the huge potential costs. Peter Christoff says the only way to overcome this short-sightedness is to end the politics and make the review independent.
Australia likely has decades of fossil fuels left to extract, export and burn. That could prove to be a problem if the world comes to an agreement on climate change. Here’s four ways to help the economy, and the climate.
Peak fossil fuel and action on climate change will mean we have less energy available to power the future.
A tiny handful of Pacific island nations control more than 50% of the world’s tuna fishery, and their efforts to monitor international fishing vessels are set to become a major source of jobs.
A growing number of researchers are looking to grief to understand how people will respond to climate change.
Revelations of live baiting in greyhound racing have sent shockwaves through the industry. Baiting is prohibited, but laws lack teeth to stamp out the practice.
Proposed laws requiring immediate reporting of animal cruelty sound like a good idea. But in practice they will make it harder to mount comprehensive investigations like the ABC’s greyhound expose.
Emperor penguins are adapted to the bitter cold of Antarctica, but a new study reveals that during the last ice age it got too cold even for them.
The terms of reference for South Australia’s Royal Commission on the nuclear industry are intentionally broad, meaning that anti-nuclear advocates will have to choose carefully where they direct their efforts.
Are kangaroos in plague proportions, necessitating large-scale killing and a commercial industry, or are they in decline?
Dead whales can cost beachside ratepayers a lot to clean up. The alternative is to tow them away before they wash up - but the legal question of who does the job is far more complex than it sounds.
