Our nation is built upon a history of immigration, dating back to our first pioneers, the Pilgrims. For more than three centuries, we have welcomed generations of immigrants to our melting pot of hyphenated America: British-Americans; Italian-Americans; Irish-Americans; Jewish-Americans; Mexican-Americans; Chinese-Americans; Indian-Americans.
Along with racial equality and the late bloom of women's rights, future generations will have to explain how, in the past, gays were misunderstood and publicly humiliated for loving each other, and, eventually, how they stood together and conquered stupidity and hypocritical hatred, and fought their way out of marginalization.
If future generations are to remember us more with gratitude than sorrow, we must achieve more than just the miracles of technology. We must also leave them a glimpse of the world as it was created, not just as it looked when we got through with it.
My whole family is spiritual. My grandmother, grand aunt, cousins, they're all preachers and pastors. Spirituality is a part of my family, from generations ago.
The most important thing about global warming is this. Whether humans are responsible for the bulk of climate change is going to be left to the scientists, but it's all of our responsibility to leave this planet in better shape for the future generations than we found it.
We have a moral responsibility to save wild places like the arctic refuge for future generations, and that is why our country has remained committed to its protection for nearly 50 years.
Looking ahead, future generations may learn their social skills from robots in the first place. The cute yellow Keepon robot from Carnegie Mellon University has shown the ability to facilitate social interactions with autistic children. Morphy at the University of Washington happily teaches gestures to children by demonstration.
For an economy built to last we must invest in what will fuel us for generations to come. This is our history - from the Transcontinental Railroad to the Hoover Dam, to the dredging of our ports and building of our most historic bridges - our American ancestors prioritized growth and investment in our nation's infrastructure.
My own view is that being a vegetarian or vegan is not an end in itself, but a means towards reducing both human and animal suffering and leaving a habitable planet to future generations.
There are two books that I often travel with; one is 'The Theory on Moral Sentiments' by Adam Smith. The other is 'The Meditations.' It's not that I agree with either views expressed in the books, but I believe ideas and thoughts of older generations can offer food for thought for the current generation.
