Wider access to reliable electricity would lead to less use of kerosene lighting and diesel generators, which are currently common in the developing world. [ 163 ] Infrastructure for generating and storing renewable electricity requires minerals and metals, such as cobalt and lithium for batteries and copper for solar panels. [ 164 ]
A group of 58 researchers is calling for a new, better way to measure obesity and excess body fat that goes beyond BMI. Here's what they recommend using instead.
