Express your opinion about whether or not either the human population or the economic wealth of humans should be a concern.
express your opinion about who should make decisions about how land is used for various human activities such as farming, industry, and recreation. what should be done if people disagree about how to use land?
express your opinion about the need for sustainable development strategies. are they necessary or not? explain your point of view. give examples to support your viewpoint.

Let's play devil's advocate just for fun. ;-)
1)  neither of them are a concern.  Even if humans overpopulate the earth, the strong will find a way to survive and Darwin's theory of evolution will determine who deserves to pass on their genes and rule the world.  This will result in stronger and stronger humans each generation.  Economic wealth is not a concern for similar reasons.  The strongest, smartest humans will pass on their genes and their wealth, thus ensuring that only strong, smart humans will survive.  
2)  People who own the land should decide what to do with it.  If there is a disagreement, they can fight about it, and call all their relatives to come back them up in a fight.  Whoever survives the fight gets to make the rules.
3)Sustainable develpment strategies are not necessary, becauase God has a plan.  We can continue to burn oil, deplete the ozone, and drive giant SUVs because God will provide for us, and then eventually he will take those to heaven who deserve it and let the rest wallow in their hellish filth. >:-)
This is a fun question.  Since it's an opinion, it can't be wrong, right? LOL
