Opinion: To feed the world in 2050 will require a global revolution

feeding the world 2050
Achieving universal food security is a staggering challenge, especially in a world with an expanding population, accelerating consumption, and many signals of a deteriorating global environment (1). Some claim that population size and growth are irrelevant, and that the solution is a more equitable distribution of income, wealth, and available food.

Ethiopia, a Nation of Farmers, Strains Under Severe Drought

MIESO, Ethiopia – Every day, Yasin Mohammed Aliye stakes out a spot on his small farm to chew khat leaves, a stimulant, and guard against intruders. The khat, he explains, helps to dull the hunger. “We got just one day of rain each month during the rainy season,” Mr. Yasin said, referring to the days from July through September.

These Solar-Powered Machines Help Farmers Dry Their Food Instead Of Letting It Rot

A lot of food grown in developing countries never makes it to the people’s bellies. Because of a lack of refrigeration, it rots during transport or when farmers fail to sell it immediately at markets. Every year, 1.3 billion tons of food (with a value of more than $1 trillion) is wasted in this way, according to the [url=]UN’s Food and Agriculture Organization[/url].

Among the poor health outcomes linked to pesticides, air pollutants, plastics and other chemicals, according to the report from the International Federation of Gynecology and Obstetrics (FIGO), an organization representing obstetrical and gynecological associations from 125 countries, are miscarriage and still births, an increase in cancer, attention problems and hyperactivity.

Molting elephant seals add mercury to coastal seawater

As fish-eating predators at the top of the marine food chain, elephant seals accumulate high concentrations of mercury in their bodies. A new study by scientists at UC Santa Cruz shows that elephant seals shed significant amounts of mercury during molting, resulting in elevated concentrations of the toxic metal in coastal waters near the elephant seal rookery at Año Nuevo State Reserve.
