Less resources is very common in under developed countries, since there is such a high population there are less resources like water,food,clothing,and housing. We need to send food and water which starts at us not wasting so many food and spending money on helping the state to recover.
Underdeveloped countries has less housing and these countries don't get the benefit of sanitation so most of there water supply is cluttered with trash. We have to help them establish good housing and more medical care.
Developed countries also get problems from having a high population it causes pollution that affect the weather causing climate change that affects crops and we exhaust our resources to accommodate the growing population and there demands that in turns affect forest and nature. We can use solar power and we have so many alternate solution but we don't use them because they are less convenient which is kind of sad.
