In my point of view, speaking about green tech, clean tech, sustainable stuffs are only the games of Europeans and partially US. People in India, China, Middle East do not really care about this in order to achieve the longly admired American Dream.
Under served, less developed countries suffered the worst. They lost connection with the world. While all 90 percent of technology and innovations only benefit the top 10% of the population in the social economy pyramid. Poor people in Cambodia rural areas have no light at night. Edison invented light bulbs decades ago. This is really strange.
Having this thought in my mind, i think we should adapt Europeans' Ideas, practice Chineses' working spirit, and seeking sustainable solutions like the Africans and Cambodians. Being a global player, we should have only one home to be bounded. That's earth.
Think of sustainable solutions, think green, help the poor and lets turn the 90/10 principal down in future.
