Did you know? Hugging a tree, even touching it, will likely make you healthier. And just being around trees has beneficial effects. Nature & Health magazine reports that, “Tree-hugging has been shown to specifically benefit depression, attention deficit hyperactivity disorder (ADHD), headaches, muscle weakness, stress and poor concentration.” Studies especially in Asia have long suggested […]
Who is credited with having made the lives of an estimated 2 billion people possible over the last century? The German chemists Fritz Haber (1868-1934) and Carl Bosch (1874-1940). How? They invented a process to produce ammonia on an industrial scale. Why is that important? Ammonia can be converted into fertilizer. And abundant fertilizer translates […]
One goal, two pioneers, three remarkable world tours between them: the first in a balloon, the second in Solar Impulse, the renowned solar-powered aircraft, and the third, less widely known, in a solar boat called PlanetSolar. Less famous than Bertrand Piccard who accomplished the first two global tours, Swiss solar navigator and aviator Raphaël Domjan nevertheless has […]
By Danielle Carpenter – According to UNICEF, “Nearly half of all deaths in children under 5 are attributable to undernutrition, translating into the loss of about 3 million young lives a year. Undernutrition puts children at greater risk of dying from common infections, increases the frequency and severity of such infections, and delays recovery.” Malnutrition can be […]

What has changed the lives of a whole bunch of people? A wild shrub with yellow flowers that grows like a weed in humid tropical areas. The plant, called Tithonia diversifolia, can be used as a fertilizer to increase cereal or vegetable yields. Made into “green manure”, its effects are equivalent to those produced by […]
Portugal is using goats to keep wildfires at bay. Goats grazing on arid land eat the dry brush that helps fires spread easily. They also trample the grass, which makes it less likely to burn. The goats are being used to feed on the vegetation in areas that are highly susceptible to catching on fire, […]
One way to eliminate artificial fertilizers, herbicides and pesticides is to let ducks paddle in rice fields and waddle in vineyards. In what is now called integrated duck farming, specially raised ducks are put into rice paddies and fields to weed the areas and eat insects. At the same time, their manure becomes organic plant food. Farming […]
