I have read that more than 15,000 children die every day from lack of nutrition. Compared with this, what happened in Paris and even 9-11 seem less important. Human beings are tribal. We have a natural affinity for those who are like us and we tend to disregard those who are different. I feel that religion is one attribute that divides us, but there are other important divisions, including race, ethnicity, economic class, sexual orientation, nationalism, language and geographic proximity. Sadly, the trillion dollars or more per year that is spent on the military, prisons and other coercive measures would be more than enough to feed every starving child, and probably most of the adults. Ironically, most religions agree that we should treat others as we would like to be treated. It seems to me that the key to making the world better will be educating people to accept their differences and work together. If aliens invaded tomorrow, I think that the nations of the world could unite, like the U.S. was able to unite with the USSR against Germany. Short of that, I think that we need to better educate people as to where the wealth is flowing and what the world could be like if we could work together to address the real problems, starting with starving children. I wish that the leaders of the major powers would declare war against starvation and poverty, and agree to devote increasing parts of their military budgets to "bombing" poor countries with food, water projects and schools. Bark, I do see progress over long periods of time. Slavery (in the classic sense) has been eliminated in most places, women have gained a greater measure of equality in most places and some historic enemies have become friends (such as Britain and France and the U.S. and Japan). Obviously we have a long way to go and the path will not be easy, but I am hopeful that over the next hundred years or so we might be able to accelerate the pace of positive change. 500 years ago, most people were slaves, serfs or the like and most countries were ruled by kings/queens/emperors and the like. In most places, women's rights were very limited, gay people were subject to execution and only the wealthiest people could read and write. I think that we have come a long way and we still have a long way to go. People who care about others need to overcome the politicians and the entrenched powers. Martin Luther King overcame the racist bastions of the South -- nonviolent resistance and peaceful activism can be effective strategies over the long run.
