Depending on the source, anywhere from 20 to 40 percent of produce in America ends up wasted. One reason why so many fruit and vegetables are thrown out is because they do not conform to what retailers and consumers believe fresh food should look like. Tomatoes too wide for a hamburger bun, carrots that look like something out of an anatomy textbook, and cucumbers that dare to be curved almost never make the shelves at grocery chains from Walmart to Whole Foods. But Whole Foods, the supermarket that has arguably made organic and socially-conscious foods mainstream, announced that it will start selling “ugly” fruits and vegetables.

Compelling evidence suggests exercise is an important component of cancer prevention and care; slashing your risk of developing cancer, improving your chances of successful recuperation, and diminishing your risk of cancer recurrence.

A pattern revealed in these studies is that the longer you exercise, the more pronounced the benefits. Studies show that both men and women who exercise during their early years have a lower risk of cancer later in life.

But like most things in life, exercise must also be done in moderation and be balanced. There is a sweet spot and excessive exercise can cause its own set of issues, but most in the U.S. are far from being at risk for this problem.

Una de las cuestiones más críticas en torno al cambio climático es la forma en que podría afectar el suministro de alimentos para la creciente población mundial. Un nuevo estudio realizado por investigadores de las universidades de Tufts y Brown sugiere que los investigadores han estado pasando por alto el cómo dos respuestas humanas clave para el clima, la cantidad de personas que optan por la tierra agrícola, y el número de cultivos que plantan, tendrán un impacto en la producción de alimentos en el futuro.

Studies of how climate change might affect agriculture generally look only at crop yields — the amount of product harvested from a given unit of land. But climate change may also influence how much land people choose to farm and the number of crops they plant each growing season. A new study takes all of these variables into account, and suggests researchers may be underestimating the total effect of climate change on the world’s food supply.

The number of African rhinos poached in 2015 is higher than previously thought with new figures from the International Union for Conservation of Nature (IUCN) showing that a record 1,338 were killed across the continent last year – 33 higher than earlier estimates.
 
This is the highest level since the current poaching crisis began in 2008 and takes the number of African rhinos killed since then to at least 5,940.
