How you prepare your coffee at home (and wash up the mugs) can have a big impact on its carbon footprint. So fill that kettle carefully, and only brew what you know you'll drink.

Plastic bags will soon be gone from major supermarkets and many other shops too. Campaigns to reduce plastic even more should focus on positive advice, rather than shaming shoppers for their plastic use. Louise Moana Kolff, Lecturer, UNSW Licensed as Creative Commons – attribution, no derivatives.

Feral rabbits previously exposed to myxoma virus are more likely to be killed by rabbit haemorrhagic diease, meaning that these two biocontrol agents can become even more powerful when used in tandem.

There are calls from the backbench and elsewhere for the federal government to safeguard the future of coal. But do those calls make economic sense? A look at Queensland's energy landscape suggests not.
