What are the two major causes of the rise in the number of overweight children? a. environmental and genetic factors
C. video games and fast food
b. diet and level of exercise
d. none of the above

C. video games and fast food

Explanation:

1.

too much video game playing may cause problems. It's hard to get enough active play and exercise if you're always inside playing video games. And without enough exercise, kids can become overweight. Overdoing video games also could affect other important stuff, like friendships and how well a kid does in school.

2.

fast food is high in sodium, saturated fat, trans fat, and cholesterol, it isn't something you should eat often. Eating too much over a long period of time can lead to issues such as high blood pressure, heart disease, and unwanted weight gain.
