Sustainability discussions have mostly centered around energy, water, land, natural resources, and food sources. Biodiversity has been a critical part of these discussions. But, for the most part the human equation in all of this tends to be downplayed, with the exception of how we can individually change our behaviors. Most societies skirt the subject of human sustainability. By human sustainability I am focusing on world hunger and the exponential growth of human kind. We cannot sustain the populations we have in place. According to The World Food Programme of the United Nations over a billion people will go hungry. Governmental aid programs are not sustaining the hunger that exists. Our own country provides 50% of the budget for this world wide program. Sustainability for people is not just feeding them, but providing the access they need to clean water, health services, economic prosperity, and a biodiversity filled environment. The current population cannot be sustained with the resources we have on hand. War and famine would disappear if there was not this economic and religious conflicts for resources. Religion plays a role here too. We can no longer deny the combat that exists between religions that seek to expand their influence through shear propagation. Both Muslim and Christian religions seek to have their members do nothing but reproduce. The Earth’s resources cannot sustain this overall explosion of humanity. The countries of India and China need to find ways to reduce their populations as well. Even the US needs to find a way to zero growth population. Human sustainability in feeding people around the world has eroded due to economic times and human population explosions. We need not to just get our own environmental homes in order, but we need to address the shear number of people on this planet as well. For more information on helping out, visit www.wfp.org/.
