For decades Australian scientists have, clearly and respectfully, warned about the risks to Australia of a rapidly heating climate. After this season's fires, perhaps it's time to listen.
2019 was a big year for dire warnings about the state of the planet, but crises can spur solutions.
New research has revealed 100 plant and animal species have become extinct in the past two centuries – a far higher number than previously thought.
Indigenous people used small fires skilfully to prevent larger bushfires. In this time of crisis, we must learn from them.
The Earth has experienced five periods of mass extinction. Scientists can't quite be certain yet, but they're fairly sure we're now well into the sixth.
Discussions about climate change often skirt around the issue of population growth, but it is the main driver of rising carbon dioxide levels and many other environmental changes on a planetary scale.
Governments fail to imagine how worst-case scenarios can come about – much less plan for them. But there are things we can do.
Our prevailing relationship with nature is based on framing the living world as a set of natural resources. This utility-based worldview perpetuates the drivers of ongoing biodiversity loss.
Democracy is not perfect. Sometimes it produces policies that are undemocratic and unjust. In those cases, breaking the law may be justified.
Polar regions may be becoming more profitable, but these "benefits" come with far more severe costs.
It's unlikely that all species of bees will go extinct anytime soon – but current losses could still have a terrible impact on food supplies and ecosystems.
Given Africa’s projected population growth, management of its environment must be a global priority
Scrapping the idea of a species is an extreme idea – but perhaps a good one.
As climatic conditions change, plants’ odours are altered, with direct consequences for pollination, especially by bees.
The global focus on plastic pollution isn't a distraction from other planetary issues.
New research has found that different types of habitat loss can change the stability of whole plant and animal communities.
The impact of deforestation for oil palm plantations is well known – and now research has found the replanting process could be additional harm to biodiversity.
Current environment laws are manifestly failing Australian animals.
Invasive species are the biggest single threat to Australian plants and animals.
It's hard to say exactly how many koalas are in the wild, but there's no doubt they're in serious trouble.
