Paolo Lugari has a plan for humanity. And he’s convinced it’s the only plan that will ensure human survival on Planet Earth: We need to plant trees. Many trees!

Joost Wouters is an unusual farmer. He does not have a tractor to prepare the soil. There is no barn on his farm. He does not even have land. Wouters grows seaweed in the ocean. He is a blue farmer.

Why is yoghurt the best extinguishing agent when your tongue is on fire with chili peppers? That was the question that Swedish inventor Mats Nilsson asked himself when he was looking for a healthy alternative for flame retardants.

Years ago, American neurologist David Perlmutter discovered an interesting connection among his patients. He determined that many of his patients with neurological problems also showed symptoms of stomach and intestinal problems.

At one point in his career, Zach Bush, MD was so disillusioned with medicine, with his inability to understand the real causes of disease and to make his patients fundamentally healthier, that he decided to extend his training to hospice care. He felt he could really help people ease into the process of dying. Helping people through the death transition, he experienced death as not just an end.

It is a secret, oncologists rarely share with their patients: Around 25 percent of all cancers are currently considered untreatable, and the prognosis is worse for colon (colorectal) and lung cancers, with half of these immune to chemotherapy.

The Covid-19 pandemic has taught us a couple of things: We cannot take what we hear or read at face value, and it is up to all of us to join the dots for ourselves.

We already know that the SARS-CoV-2 virus, which causes Covid, is twice as virulent as seasonal flu, from the same SARS family, which puts its mortality rate at around 0.4 percent. For more than 90 percent who get the virus, it will cause mild symptoms. According to health agencies, 30 percent will not even know they have it, and will be entirely symptom-free, or asymptomatic.

For three decades, I have been documenting the lives of the Ju/’hoansi people of the north-western Kalahari, and their often-traumatic encounter with modernity. The Ju/’hoansi are perhaps the best known of the handful of societies who still sustained themselves by hunting and gathering well into the 20th century. And to them, very little about the relentlessly expanding global economy makes sense.

Dr. Mark Hyman knows that bad food makes people sick. He has been using food as medicine for 30 years achieving spectacular results like completely reversing type 2 diabetes within a week or two. Then, one day in 2014, he realized that treating patients in his doctor’s office meant he was merely treating symptoms of a much bigger problem. The real treatment, he thought, had to start at the roots of the food chain: on the farm, in the grocery store and in the kitchen at home.

Ancient knowledge can make a major contribution to the fight against the coronavirus. Recently, the New England Journal of Medicine published a study that found that the virus lasted only briefly on copper, compared with days on stainless steel and plastic. The outcome should not have come as a surprise.
