An anthropogenic mass extinction is underway that will affect all life on the planet and humans will struggle to survive the phenomenon. So claims Dr Rosemary Mason in a paper (2015) in the Journal of Biological Physics and Chemistry. Loss of biodiversity is the most urgent of the environmental problems because this type of diversity is critical to ecosystem services and human health. Mason argues that the modern chemical-intensive industrialised system of food and agriculture is the main culprit.

Is the supposed safety advantage of GMO crops over conventional chemical pesticides a mirage?

According to biotech lore, the Bt pesticides introduced into many GMO food crops are natural proteins whose toxic activity extends only to narrow groups of insect species. Therefore, says the industry, these pesticides can all be safely eaten, e.g. by humans.

Sixth-extinction estimates are “biased towards a very small portion of biodiversity”. When it comes to invertebrates – the slugs, crabs, worms, snails, spiders, octopuses and, above all, insects that make up the bulk of the world’s animal species – we are guessing.

Dr James Hansen is rightly admired for his scientific and political work drawing attention to climate change. His advocacy of nuclear power ‒ and in particular novel Generation IV nuclear concepts ‒ deserves serious scrutiny.

In a nutshell, Dr Hansen (among others) claims that some Generation IV reactors are a triple threat: they can convert weapons-usable (fissile) material and long-lived nuclear waste into low-carbon electricity. Let's take the weapons and waste issues in turn.

The EPA was only four years old when glyphosate entered the market in 1974, and the agency was faced with a large collection of chemicals to review. At the time, protocols for toxicology testing were relatively fluid, and it took the EPA until 1986 to finalize its guidelines. Yet the EPA’s analysis of glyphosate still relies heavily on the initial data.

Imagine you’re driving your shiny new car too fast along a wet, curvy road. You turn a corner and realize you’re heading straight for a crowd of pedestrians. If you slam on your brakes, you’d probably skid and damage your car. So you keep your foot on the accelerator, heading straight for the crowd, knowing they’ll be killed and maimed, but if you keep driving fast enough no-one will be able to catch you and you might just get away scot-free.

The number of people suffering from malnutrition worldwide rose to 815 million in 2016, rising by 38 million from the year before. According to a new report co-signed by five United Nations agencies and charities, and made public by the Food and Agriculture Organisation of the UN (FAOUN) on Friday, this was the first such year-to-year increase since the beginning of the 21st century.

The development of science and technology, and their spread around the world in the form of gigantic increases in food production, have made possible a century-long reduction in the number suffering from hunger and malnutrition. In 2016, the world produced more than enough food to provide an adequate and nutritious diet to every human being on the planet.
