If we had to live on at least one planet in our solar system for a day, which planet would be faster to get to?

My answer would be The Moon

Why?: Well, The Moon has at least a little bit of oxygen so people should be able to breathe as long as they are in their suits. The problem is, mars doesn't have water, and it doesn't rotate. So ageing would either be faster or slower on The moon. At least you can get a good view on the moon.

The Moon should take something around 3 days to get there. Since the moon doesn't rotate, one side of the moon is hot and the other side is cold, while one side is dark and the other side is lighter. The moon is a odd place to go on but if it were for one day, The Moon is a good answer

they had the law tat factories that produces smoke cannot be built near residential buildings.

building of proper sewage system was done to ensure that the waste is carried away from the humans so that they do not get diseases from it.

also they built water systems to provide water in those areas which are drought prone.
