  1. Thanks for your comments. I’d note that underlying population growth are issues that directly affect individuals like these two young girls: educating and empowering women, for one, which can have a significant impact on development, family size, public health, etc.

    The post is not an “article about the population problem,” but rather points to other sources of information on the issue, with varied views — hence “8 ways to…” The intent is to help people learn more about the issues. The picture was intended to encourage people to think about the human impacts. It was not intended to suggest those two girls are the problem. Sorry if you interpreted it that way.

    I looked at it this way: The girls are two reasons we should engage with these issues. DF

When everyone recognizes that there is a need to talk openly about population growth and the importance of family planning, the empowerment of women, and reproductive health and rights, we can more easily find the solutions to issues like global hunger and the environment. When people discover how a rapidly growing world population affects them and their hopes for the future, we know that more people, particularly young adults, will want to lend their voices to the global discussion.
