We Need to Cull At Least 1 Billion of the Population

First I would like to reiterate the issue with the morality of slaughtering 1 billion innocent people. Most people, I imagine, would agree that murder is wrong. Many would think execution of criminals is wrong. War is widely recognized as horrible despite the good it can ultimately accomplish such as stopping Nazi Germany. More so, those who committed genocide or mass murder like Hitler and Mao Zedong are considered some of the most horrible people ever. Now let’s consider the numbers. My opponent wishes to kill 1,000,000,000 people. In the 20the century an estimate 167-268 million people died due to war. Less than 3/10s my opponent wants dead. http://necrometrics.com... In the holocaust an estimated 15-20 million people in total were slaughtered. The result of this is that Hitler is considered among the most evil people of all time. Yet my opponent wants to kill over 5 times as many. http://www.nytimes.com... The most horrific death tolls of war and genocide in 20the are mere fractions of the number of people my opponent wants dead. This should illustrate just how morally bankrupt my opponent’s position is. My opponent does make a good point that human kind’s population growth is unsustainable. However I would like to put forward two points. First with as terrible an act as killing a billion people is, any other way of preventing the effects of overpopulation should be chosen. Second my opponent used worldwatch.org as a source for his/her data and the carrying capacity of earth. My opponent uses this as evidence that the greatest massacre in history must be performed, yet his/her own source comes to a different conclusion about what to do about it. This is what worldwatch.org says their purpose is: Through research and outreach that inspire action, the Worldwatch Institute works to accelerate the transition to a sustainable world that meets human needs. The Institute’s top mission objectives are universal access to renewable energy and nutritious food, expansion of environmentally sound jobs and development, transformation of cultures from consumerism to sustainability, and an early end to population growth through healthy and intentional childbearing--http://www.worldwatch.org... The conclusion worldwatch.org comes to is that we need to transition to sustainable energy, environmental, and agricultural processes. Most importantly their solution to unsustainable population growth is to end it by encouraging “healthy and intentional childbearing.” My opponent would have you believe the best way to prevent overpopulation is perpetrating the greatest massacre in all of history, yet his/her own source advocates a far more humane way of preventing overpopulation and its effects. My opponent is also hypocritical in his/her appeal to readers to agree. He/she says: You should listen for your children, and if you plan for them to live on this Earth. To grow. Love. And have children of their own. Yet he/she would rob 1/7 of humanity of that chance. He/she implies that those to be killed would be chosen based on disability, poverty, and specific locations, but never explains who is going to make the decisions of who dies and who lives. In all likelihood it would be those in power committing genocide against groups they dislike. Now I will end with a question to my opponent: If you are so eager to slaughter 1 billion of our population would you volunteer?
