Using condoms the answer?

After reading the email about condoms I was intrigued to find out more information on it. Because I agreed, it first must be proven that population does effect climate change. I found an article online which stated “A larger global population means a larger demand for everything--most urgently, energy. And although Earth's resources have apparently stretched, the mounting climate problem suggests that the consequences of overconsumption (namely of coal and other fossil fuels that produce heat-trapping greenhouse gases) may still be inevitable.” The website for this is http://www.thebulletin.org/web-edition/roundtables/population-and-climate-change.
