How is the production of NADPH useful for the process of photosynthesis?

hi,

the answer is third world countries, take for instance china, they restricted each family with only one child,

hope this !

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.
