I think it's B, because recycling reduces mining and drilling, both of which cause air and water pollution. Hope this made sense lol it's the closest one to the the true answer
CORRECT
Having body fat contributes to having a menstrual cycle. If a woman loses too much body fat, she can stop having her menstrual cycle because you need a certain amount for it to be able to function as normal. I don't think the body would benefit from ceasing to menstruate, because at that point it isn't really healthy. However, usually if a woman gains back some of the body fat or starts eating fattier foots/exercising less, her period will start again.
