We are Christian and Jewish and Muslim and Hindu and none of the above. We are gay and straight. We are black, brown, white, and innumerable combinations. We are young and old, female and male, with and without disabilities, urban and rural, and liberal and conservative. Every one of us is an equal American.

When I was first elected to the Senate, I was fortunate to be appointed to the Intelligence Committee. There, I saw up close the dedication and commitment of the men and women of our intelligence agencies.

When counting on learning from innovation, there are great successes but also failures. The Wright Brothers invented the aircraft and started an amazing process of innovation, where we now have planes that carry 500 passengers. Along the way there were some silly looking vehicles that crashed early on.

Oil drilling and coal mining are killing endangered wildlife, polluting rivers, creating smog over wilderness areas and blocking wildlife corridors in America's most treasured landscapes.

And they will be aggravated as the population rises to a projected nine billion by mid-century, and by the effects of climate change. An 'ecological shock' could irreversibly degrade our environment.
