Animals — the meat in the Olympic sandwich

Can forest conservation and logging be reconciled?

Plastic, like diamonds, is forever: time to use fewer bags

It would be smarter to use perennial native grasses for cereal grains instead of relying on a handful of farming-intensive annual crops. Shown here is Curly Mitchell grass (Astrebla lappacea), common in northern Australia. Ian Chivers

Splendour in the grass: new approaches to cereal production

Any investment manager will tell an investor to spread risks, to have a diverse portfolio, to engage with many sectors of the local economy, to invest in other parts of the globe, to hedge your bets, a…
The jury is still out over the environmental impacts of eReaders versus paper books. Julie Falk

Weighing the environmental costs: buy an eReader, or a shelf of books?

Bookshelves towering floor to ceiling filled with weighty tomes, or one book-sized device holding hundreds of “books” in electronic form: which one of these options for the voracious reader creates the…

Climate change and the soothing message of luke-warmism

We are familiar with the tactics, arguments, and personnel of the denial industry. Yet there is a perhaps more insidious and influential line of argument that is preventing the world from responding to…

Why the carbon-tax ‘python’ won’t squeeze the economy

Some critics of carbon pricing have pointed out that, over time, the carbon price will increase to a much higher level and devastate the economy. Indeed, the image of a python squeezing the life out of…

The Australian dingo: to be respected, at a distance

It’s the dry season in the Northern Territory, and for many people that means camping under a clear winter’s sky in the Top End. Yet rediscovering nature can be a fraught exercise in wilderness areas like…
Not winning them over… some plain speaking might have helped the Gillard government explain just how the carbon tax will impact on electricity prices. AAP

Plain speaking on the carbon tax and electricity prices

Confusion continues on how the carbon tax will hit the electricity bills of Australian households. While messages from electricity retailers may be on their way, Gujji Muthuswamy from Monash University’s…

Little by little: the benefits of Australian climate policy

A catchment threatened by salinity can’t be repaired by one or two landholders. Revegetation designed to lower watertables has its greatest ecological benefit where the plants are, but its net impact on…

These foxes are worth $10 each when killed and scalped, is it really worthwhile in controlling fox numbers, and is $10 worth the effort? David Peacock

Political dreaming: shooters solving pest problems?

The Victorian government has introduced bounties for foxes and wild dogs, $10 for the scalp of a fox, and $50 for that of a dog. Bounties have been tried before, and failed to control these pests, but…

Low-emission’s missing link: reverse auctions for clean power

Selling the carbon tax: individual versus collective self-interest
