Endangered green turtles like this one on Raine Island in Queensland’s far north face an uncertain future – one that depends largely on effective conservation measures.
With 99% of green sea turtles in the northern Great Barrier Reef hatching as females due to changing climate, the future for this species now depends largely on effective global conservation measures.

Cows produce a lot of methane. But there’s not much evidence a tax on beef would be effective in fighting greenhouse gas emissions.
A tax on beef isn't likely to achieve the intended outcome of reducing greenhouse gas emissions. Instead, it could create a spate of unintended consequences.

Is meat the new tobacco? Some are suggesting it is, and urging a “sin tax” on beef, pork and other meats.
Taxing a food product like meat, which has been entrenched in our culture for so long, is silly. We should let the market evolve and allow consumers to make their own choices.
Once we see the scale of issues like the climate change crisis, it can be difficult to imagine solutions. Collective reflection and alternative storytelling is one way to begin. Here: Youth leaders at the Climate March in New York City.
