The court ruling that it’s a constitutional right to have clean air highlights the fact that South Africa needs to improve air quality urgently.
$13 billion would buy us safe air in schools and aged care facilities. It would give the same sort of benefits as safe water.

3D printers got a lot of attention when DIYers leapt to action to address equipment shortages early in the pandemic, but some everyday items found in hardware stores played a big role, too.
Imagine if every meal you ate included food previously chewed by someone else. That’s what’s happening to the air we breathe in shared indoor spaces.

Covering the state’s canals with solar panels would reduce evaporation of precious water and help meet renewable energy goals – all while saving money.
The UK has around 2,000 drive-throughs.
Drive-throughs not only increase air pollution and emissions, but also contribute to a car-centred culture that we need to avoid.
COVID has given us the opportunity to ensure our air is as safe as our water. It needn’t be expensive.

Southern California is on the front line of climate change, and recent survey data shows that residents are feeling its effects in many ways.
Beating COVID cannot rely solely on the efforts of vaccines – economic policy must robustly support the path to full recovery, starting with healthcare and ventilation.
Vaccines alone aren’t enough to protect against the highly contagious Delta variant.

While most areas experienced a reduction in air pollution in response to lockdown measures, other areas saw only small improvements or even an air quality deterioration.
This is not an imaginary future dystopia. It’s a scientific projection of Australia under 3℃ of global warming – a future we must both strenuously try to avoid, but also prepare for.
Older homes can have a variety of environmental health risks.

Poor indoor air on tribal lands can cause a range of respiratory illnesses, including viral infections. Here’s how people are fixing the problem while preserving traditional ways.

Exaggerating how much lockdown improved air quality could allow us to underestimate the scale of the air pollution problem.
The risk of transmitting COVID-19 is much higher indoors due to proximity to other people and building ventilation systems.
Studying how SARS-CoV-2, the virus that causes COVID-19, travels through indoor air spaces can help reduce transmission risk.
This year’s World Soil Day theme is: ‘Keep soil alive, protect soil biodiversity’.
Healthy soils are vital for food, biodiversity, and a healthy planet, but this below-ground world is often overlooked. The launch of the State of Knowledge of Soil Biodiversity Report highlights this.
