And let us remember too that life, in its exuberance, always succeeds in overflowing the narrow limits within which man thinks he can confine it.

Through the window of my mask I see a wall of coral, its surface a living kaleidoscope of lilac flecks, splashes of gold, reddish streaks and yellows, all tinged by the familiar transparent blue of the sea.

We must alert and organise the world's people to pressure world leaders to take specific steps to solve the two root causes of our environmental crises - exploding population growth and wasteful consumption of irreplaceable resources. Overconsumption and overpopulation underlie every environmental problem we face today.
