This is our home

Children are watching, thinking and feeling things about the future of the environment and those feelings deserve to be taken seriously.

More trees, please

Billions of trees grow in the world’s cities, helping to cool them as temperatures rise, support biodiversity and make urban areas more liveable.

Attenborough at 100

As Sir David Attenborough turns 100, we reflect on what makes him the world’s most beloved conservation communicator and why his greatest lesson is making us care about the vanishing natural world.

Long hot autumn

After a long, hot, humid summer, cooler showery weather has finally arrived in Sydney. Much of Australia has suffered unusually dry, warm weather this autumn, so what are the causes and what will winter look like?

Where the wild things are

The Chernobyl disaster tapped into our enduring fascination with radiation and mutation, with all sorts of claims being made about damaged wildlife and mutant animals in the exclusion zone but clear scientific evidence for significant long-term radiation effects is surprisingly hard to find.

The brown marble

The photos of the ‘blue marble’ of Earth taken by the Artemis astronauts were noticeably more arid than those taken by Apollo 8 and the loss of Earth’s life-giving forests shows no sign of abating as populations increase and ever more land is logged, burned or cleared for agriculture.

Staring into the abyss

Stanford University biologist Paul Ehrlich, who died March 13, 2026, in Palo Alto, California, was a scientific crusader whose dire predictions about population growth, world hunger and environmental collapse made headlines and sparked controversy for decades.

The crucible of early life

On the shores of the west coast of Australia lies a window to our past. The stromatolites and microbial mats of Shark Bay are living “relics” of ancient ecosystems that thrived on Earth billions of years ago.

Our overburdened Earth

The Earth has already exceeded its ability to support the global population sustainably, with new research warning of increasing pressure on food security, climate stability, and human wellbeing. However, slowing population growth and raising global awareness could still offer humanity some hope.

Being human is not a race

The division of the human family into ‘races’ is unnecessary and counterproductive, influencing important decisions concerning the environment as well as the safety, health, social and economic wellbeing of the population as a whole.

A breath of fresh air

We can live for three weeks without food, three days without water but just three minutes without breathing and though we take it for granted, the quality of the air we breathe touches on many social as well as environmental issues.

The invisible invasion

While research is still emerging, the ubiquity of microplastic exposure through food, water, and air has prompted scientists to call for more comprehensive studies on long-term health effects.
