How does underdevelopment affect the citizens of less developed countries

Underdevelopment causes hunger, disease, poverty, resource scarcity,environmental degradation, exploitation,exclusion,health problems,lower GDP, no education and lower standard of living to citizens of less developed countries.Around 3 billion people of this world are facing underdevelopment.

The nations with underdeveloped people/society supply cheap labour,and consumer markets for the wealthy nations ,without which,according to Dependency Theory, they could not have the higher standard of living they enjoy.eg big companies like Nike,Adidas,Coca Cola,Pepsi etc have their factories in poor countries to enjoy cheapest labour and many a times young children below 14 years,to work for them,so that they may enjoy higher profits.

biological/genetic factors means they were born or predisposed to have something. nothing can really change it, and you can't really do much to "fix" it. it isn't something learned

these are the biological factors:

adrian is relatively tall and he is on the basketball team

(adrian can't ever stop being tall or force himself to be tall. likely one or both of his parents are tall as well and they passed on the tall gene. he probably does basketball because he is tall)

the rest are environmental/cultural factors. these are things that are taught to us. for example, cynthia wasn't born saving pocket money, her family most likely taught her this (environmental factor)

hope this !
