In many cases, human population is not the problem. Human greed is.

No 7 billion people couldn't live as we do in the USA, But 7 billion could have enough food and water, a clean place to live and access to cell phones and the Internet.(Think smaller homes, balcony gardens and composting toilets to make soil for biofuels.) Our lifestyle is wasteful and most of our luxuries do not enhance our quality of life.
