When communities watch young people grow up, go off and never return, remaining residents and politicians often bemoan there’s been a “brain drain” — especially when such population loss means schools and businesses close. But plenty of residents are full of love and pride for those communities, and some are working to identify their towns’ best attributes so they can attract new residents and achieve “brain gain.”
As agriculture intensified in the 20th century, summers in the Midwest became wetter and cooler. Researchers at MIT, in a study published this month, looked at whether vegetation from crop production, rather than the greenhouse gas emissions that are an established source of climate changes, could have driven these regional impacts.
No matter how far fruits or vegetables travel, whether they’re grown organically or conventionally, they’re packed with vitamins, minerals and other necessary nutrients. The men and women in the fields try to grow foods with an eye to boosting the health factor, but researchers say it’s hard to measure the precise impact.
