Portulacaria afra is a slender, evergreen shrub with small, rounded succulent leaves. It has a varied growth habit; in the Addo Elephant Park the plant grows wide with a loose, rounded shape due to its … [Read more...]
Apple facilities now running on 100% renewable energy
You have to see Apple’s Reno, Nevada, data center from the inside to truly understand how huge it is. It’s made up of five long white buildings sitting side by side on a dry scrubby landscape just off I-80, and the corridor that connects them through the middle is a quarter-mile long. On either side are big, dark rooms–more than 50 of them–filled with more than 200,000 … [Read more...]
How business can help us achieve sustainable development goals
Taking climate action, safeguarding life below water, reducing inequalities, and promoting responsible consumption and production: The global community adopted these four targets as part of the 17 Sustainable Development Goals (SDGs) it wants to achieve by 2030, but is likely to fail to do so unless the business community steps up to deliver solutions that will help achieve the … [Read more...]
Leading pesticide destroys healthy microbes in humans and soil
We're only beginning to learn the importance of healthy gut bacteria to our overall health—and the relationship between healthy soil and the human microbiome. We know that the human microbiome, often referred to as our "second brain," plays a key role in our health, from helping us digest the food we eat, to boosting our brain function and regulating our immune … [Read more...]
It’s economically beneficial for SA to protect its natural capital
Healthy natural landscapes such as veld, wetlands, rivers, and estuaries across South Africa generate value to the economy amounting to at least R275 billion per year, a new study by economists at the University of Cape Town (UCT) has found. This is equivalent to at least 7% of the national gross domestic product (GDP), or three times the annual combined value generated by the … [Read more...]
Resistance is fertile! Farmers rise up against SA’s corporate seed laws
Calls to decolonise our seed system at Gauteng public hearings on the Plant Improvement and Plant Breeders’ Rights Bills. Are there alternative systems that put farmers at the centre, do not reduce genetic and agricultural diversity, and support agroecology, seed and food sovereignty and resilience?

Imidacloprid is a terrifying chemical used on much of the world's fruits and vegetables -- and it's threatening our web of life from bees to insects. Now … [Read more...]
Scientists accidentally discover efficient process to turn CO2 into ethanol
If scientists can figure out how to convert atmospheric carbon dioxide into fuel - and do it at an industrial scale - it would, quite literally, change the world. Last month, we hit the highest levels of atmospheric CO2 in 4 million years, and it’s now permanent, meaning we’ll never be able to drop to 'safe' levels again. But if we can turn CO2 into a fuel source, we can at … [Read more...]
Carbon nanofibres made from CO2 in the air
Scientists in the US have found a way to take carbon dioxide (CO2) from the air and make carbon nanofibres, a valuable manufacturing material. Their solar-powered system runs just a few volts of electricity through a vat full of a hot, molten salt; CO2 is absorbed and the nanofibres gradually assemble at one of the electrodes. It currently produces 10g in an hour. The … [Read more...]

Image series shows ozone hole development since 1979
The stratospheric ozone layer protects life on Earth by absorbing ultraviolet light, which damages DNA in plants and animals (including humans) and leads to skin cancer. Prior to 1979, scientists had not observed concentrations below 220 Dobson Units. But in the early 1980s, through a combination of ground-based and satellite measurements, scientists began to realize that … [Read more...]
