Should countries like China be able to dictate how many kids families can have? Why or why not?

I DONT KNOW WHAT TO SAY IN WAY ITS GOOD BECAUSE, IF THERE IS MORE PEOPLE THERE CAN BE LESS FOOD GROWING , MORE POVERTY AROUND THE WORLD

AND DISEACES CAN SPREAD.... IN THE OTHER HAND IT WOULD BE NICE TO HAVE AS MANY CHILDREN AS YOU WHAT AS LONG AS YOU CAN TAKE CARE OF THEM.... WELL I GUESS EACH ONE HAS THERE UPS & DOWNS TOO IT ....
