The Klan had used fear intimidation and murder to brutally oppress over African-Americans who sought justice and equality and it sought to respond to the young workers of the civil rights movement in Mississippi in the same way.

Rosa Parks was the queen mother of a movement whose single act of heroism sparked the movement for freedom justice and equality. Her greatest contribution is that she told us a regular person can make a difference.

Women have a lot to say about how to advance women's rights and governments need to learn from that listen to the movement and respond.

The environmental movement like all political processes reacts best to disasters. But these are very slow very gradual disasters in the making.

A fascinating challenge facing today's environmental movement is how to best approach the reversal of past decisions that altered once-pristine environmental spaces for the sake of urgent man-made needs.

I think an old style of addressing environmental problems is ebbing but the rise of the so-called conservative political movement in this country is not a trend towards the future but a reaction to this very broad shift that we are undergoing.

There is no question that photography has played a major role in the environmental movement.

Ted Turner is still a leader. And he sets a great example. His ability financially has been reduced but his influence and his example still is an important asset to the whole environmental movement.

I really believe in the environmental movement right now - it only takes a little effort to make a big difference.

In the environmental movement every time you lose a battle it's for good but our victories always seem to be temporary and we keep fighting them over and over again.
