Answer:
B. Making highway medians a minimum of 3 feet wide.
Explanation:
According to the World Health Organization, obesity is becoming the disease of our times, with approximately 1 out of every 4 people being overweight. Obesity leads to a myriad of health problems, like diabetes and heart problems. The main causes of obesity are a poor diet, and a sedentary lifestyle.
In order to combat obesity, several changes to the social environment can be made. Well lit sidewalks can contribute by encouraging people to go out for a walk after sunset, which given common work and school schedules, it's when most people have the time to go out and exercise. Many people don't ride a bike due to the danger of being hit by a car, so constructing safe bike paths would be a move in the right direction. Finally, many people are obese because they only have access to greasy and sugary foods, so increasing availability of nutritious food options would help diminish consumption of unhealthy food.
Making highway medians wider won't probably have an effect on obesity. Investing in highways means pouring money into the car industry, with vehicle use being linked to higher obesity. Also, most highway medians are inaccesible, and reaching them can be extremely dangerous for pedestrians, due to the high traffic.
