For the pyrethroid and neonicotinoid pesticides tested in this study, this pattern has not been documented before. (2016-04-04)

People waste nearly a pound of food daily
Americans waste nearly a pound of food per person each day, but the exact amount of food we trash differs by how healthy your diet is, a new PLOS ONE study finds. Between 2007-2014, consumers wasted nearly 150,000 tons of food per day. Researchers estimate that food waste corresponded with the use of 30 million acres of land (7 percent of total US cropland) and 4.2 trillion gallons of water annually. Higher quality diets were associated with higher levels of food waste. (2018-04-18)
