Our surest protection against assault from abroad has been not all our guards, gates and guns, or even our two oceans, but our essential goodness as a people. Our richest asset has been not our material wealth but our values.

We've been a country that's been fortunate to be protected by two oceans, to not have serious attacks on our territory for most of our history. And we were unfortunately reminded in a very devastating way of our vulnerability.

This is the moment when we must come together to save this planet. Let us resolve that we will not leave our children a world where the oceans rise and famine spreads and terrible storms devastate our lands.

The 2008 election settled nothing, not even for a while. Our national politics are reflecting what appears to be going on geologically, on the bottom of the oceans and beneath the crust of the Earth: the tectonic plates are moving.

To myself I am only a child playing on the beach, while vast oceans of truth lie undiscovered before me.

We do not have the luxury of two big oceans protecting us as we have had in the past, for we now have a new kind of enemy who deals with stealthiness. Our ability to protect ourselves is having the information ahead of time so we can thwart the attack.

Neither our oceans nor our radar nor our fighters can keep us intact through another major war.

It isn't the oceans which cut us off from the world - it's the American way of looking at things.

We are opening up an enormous new era in archaeology. Time capsules in the deep oceans.

Neither does man have gills for living in a water environment; yet it is not sinful to explore the depths of the oceans in search of food or other blessings.

Before computers, telephone lines and television connect us, we all share the same air, the same oceans, the same mountains and rivers. We are all equally responsible for protecting them.

Global warming has melted the polar ice caps, raised the levels of the oceans and flooded the earth's great cities. Despite its evident prosperity, New Jersey is scarcely Utopia.

What I mean by that is that the point of life, as I see it, is not to write books or scale mountains or sail oceans, but to achieve happiness, and preferably an unselfish happiness.

Some things are only capable of being done in space. Examples of that are looking at our Earth from that far away, and understanding the entire processes of storms and weather patterns, and oceans, and coastlines.

I think the Caribbean countries face rising oceans and they face increase in the severity of hurricanes. This is something that is very, very scary to all of us. The island states in the world represent - I remember this number - one-half of 1 percent of the carbon emissions in the world. And they will - some of them will disappear.
