What I mave observed in these months that healthy and wealthy nations are rich in vegetation also .
Its child health, health care old age care which is important but still important is education of parents to have good parenting.
Rich nations have higher level of education, children and borne far and few , their health is good Parents spend less time taking them to hospitals because they pay full attention and care.
Healthy children produce healthy nation and healthy people work hard to produce wealthy nations.
When will poor countries understand that their major problem is not pollution their problem is population and unless they control their population they cant enjoy the fruits of development in equitable manner. Health and weath go together. And both require a good natural habit and habitat.
