Australia has one of the worst track records in the world for species extinctions. The federal government’s proposed changes could weaken our already inadequate environment law.
Enabling wildlife to journey across farmlands not only benefits conservation, but also people. It means bees can improve crop pollination, and seed-dispersing birds can help restore ecosystems.
The development is significant for several reasons – not least that Australia’s progress under the Paris Agreement is being linked to its stewardship of the reef.
An emissions trading scheme is New Zealand’s main policy to tackle climate change. But to bring down emissions quickly enough, other policies will need to transform transport and agriculture.
Tassie devils are notorious scavengers, eating everything from echidnas to stranded whales. Understanding how their teeth wear down can help us feed and protect captive populations.
When the snake is ready to shed its skin, it rubs its body along rocks, plants and other rough things to peel the old layer of scales — often in a single, snaky piece.
Peatlands worldwide are running short of water, and the amount of greenhouse gases this could set loose would be devastating for our efforts to curb climate change.
A complete switch to biofuels is neither feasible nor desirable, but they could replace some fossil fuels in transport and heating. If biofuels are produced from waste products, that’s even better.
A better understanding of the science behind falling trees – followed by informed action – will help keep us safe and ensure trees continue to provide their many benefits.
For phascogales, tree hollows are getting harder to find. I venture into forests and study how well artificial hollows made with chainsaws can replace them.

Keeping global warming under 1.5°C is still achievable with rapid deployment of renewables. A new report found solar and wind can supply the world’s energy demand more than 50 times over.
One cold winter doesn’t negate more than a century of global warming. We need the political leadership to set the world on a safer path. Ill-informed tweets by government senators won’t help.

Renewables form an ever-greater share of the electricity mix. But elsewhere in the energy sector – in transport, industry and buildings – emissions reduction is very slow.
The electric vehicle transition is about more than just scrapping petrol cars. We must also ensure quality technology, anticipate the future and make sure no-one gets left behind.
New research looked at wave conditions over the past 40 years, and found wave power has increased since at least the 1980s, mostly in the Southern Hemisphere.

Indigenous marine governance is experiencing a revival throughout Oceania, building on traditional worldviews that acknowledge connections between people and all parts of ocean ecosystems.
Rather than considering the job done, Tasmania should seize opportunities including renewable energy, net-zero industrial exports and forest preservation.
