For no particular reason:
“We live in one global environment with a huge number of ecological, economic, social, and political pressures tearing at its only dimly perceived, basically uninterpreted and uncomprehended fabric. Anyone with even a vague consciousness of this whole is alarmed at how such remorselessly selfish and narrow interests – patriotism, chauvinism, ethnic, religious, and racial hatreds – can in fact lead to mass destructiveness. The world simply cannot afford this many more times.”
