Imagine you are an environmentalist giving a speech about environmental concerns due to population growth in the western united states. which detail would be the most important to include?
destruction of the desert due to overpopulation
impact of urban sprawl on the rocky mountains
depletion of freshwater due to city growth
heavy mining of gold in northern california

If I was an  environmentalist giving a speech about environmental concerns due to population growth in the western United States, the most important detail I would include is option C: depletion of freshwater due to city growth.

Water is not used efficiently, so it would be a really serious issue to deal with, if a population growth takes place and result in the depletion of water.

For instance, the scarcity of fresh water for agriculture may emerge as a more immediate problem. Almost one-fifth of the world’s population lives in areas where water is physically scarce, so that a rapid and increasingly population growth has given way to an enormous expansion of agriculture, which is now estimated to account for 92 percent of the world’s use of fresh water.

most people were factory or company owners.

depends on the age of the teen, many believe by the age of 16 a person should know the strong difference between right and wrong along with the difference between risky and immediate death. swimming with sharks might be dangerous but swimming with sharks while bloody meat is attached to you is just insane. even more if you have no idea what you're doing. however, no matter the age, as long as the person is skilled enough and has the mental and physical capacity to control their actions doing whatever sport they put their mind to is all that matters.
