Despite recent technological developments in electric, hybrid and autonomous vehicles, many cities are opting to clear their roadways of automobiles to make way for alternative forms of transportation. While increasing pedestrian, cycling and public transportation routes does reduce pollution, it also creates a more convenient, pleasant way to travel through a city center than sitting in grid-locked traffic.

Conquering pollution by limiting emissions

According to World Health Organization statistics, approximately three million deaths each year are connected to air pollution, a large percentage of that stemming from car exhaust. As a result of this public health risk, many cities are focusing their efforts on reducing or eliminating gas or diesel cars from the streets. Leading the way in this effort is Oxford, whose plan will create a zero-emissions zone in the city’s center by 2020. Paris will follow with a gas and diesel ban in 2030. Tokyo has already banned all diesel cars, with London scheduled for 2020 and Copenhagen one year earlier, beginning in 2019.

And this delicious but not-so-good-for-you diet is having profound effects on mice. According to a recent study, their diet may even be changing their genes.

The study, which was published last month in Molecular Ecology, involved 48 white-footed mice caught from three New York parks and three nearby rural areas. The mice are native to New York, so researchers Stephen Harris of the State University of New York and Jason Munshi-South of Fordham University wanted to see if the city mice had begun to evolve for city living.
