Population growth is ten times more scary and I guess its all tied. There are lots of things being done, we just don't see it. The birth rate around the world has steady been declining over the past decade and half. The U.S birth rates have hit a all time low in the past two years.

Fact is that although its declining, its coupled by various factors such as low mortality rates, technological advancement, medicine etc. We are adding about 74 million new people to the world a year.
Average life span use to be around 45 years, its now increased to 75 years...so people are not dying as fast as they use to.
We are expected to have 9 billion people in 2040 and close to 12 billion by 2050.
High birth rates tend to occur in urban areas and developing countries. Our best bet is education and also to help developing countries become more industrialized because statistics show that, women tend to have fewer kids in industrialized countries than in developing nations.
Lots of countries have already started to take action in the past two decades. From education to messages put in cartoons and various tv programs, to something stricter as China's law that that women can only have two children. Things are happening, its just that its too big of a problem for us to see any difference with the naked eye. Not to mention, the effects of our actions will not come about soon, but in future generations.
There are annual conferences held by the U.N where many countries meet to discuss this issue alone.
About 130 leading parliamentarians, experts and representatives of international, regional and national organizations from Central Asian, Asian and Pacific countries, will gather in Vientiane on 25-26 April for the 26th Asian Parliamentarians? Meeting on Population and Development, focused on Population and Adaptation to Climate Change. The forum is an annual meeting of the Asian Population and Development Association (APDA), chaired by the former Prime Minister of Japan, Hon. Yasuo Fukuda, MP.
"The projected doubling of global urban population within a generation, mostly in the developing world and much of it in Asia, if unmanaged can be a bigger source of greenhouse gas emissions" says Najib Assifi, Deputy Director of the Asia and the Pacific Regional Office of UNFPA, the United Nations Population Fund. ?Investments in education, health, sexual and reproductive health and youth can result in lower fertility, slower population growth and women's empowerment, all of which can contribute towards climate change mitigation and adaptation.?
