I always thought we had an environmental problem, but I hadn’t realized how urgent it was. James Lovelock writes that by the end of this century there will be one billion people left.

I’m reasonably optimistic about the future, especially the future of the United States – for the century, at least.

We have entered an age in which education is not just a luxury permitting some men an advantage over others. It has become a necessity without which a person is defenseless in this complex, industrialized society. We have truly entered the century of the educated man.

I want to use my position of leadership to help move along at a faster pace what I believe and know the Obama administration wants to do around the urgency of climate change.

Without a sense of urgency, desire loses its value.

America must not ignore the threat gathering against us. Facing clear evidence of peril, we cannot wait for the final proof, the smoking gun that could come in the form of a mushroom cloud.

When Thomas Edison worked late into the night on the electric light, he had to do it by gas lamp or candle. I’m sure it made the work seem that much more urgent.

My message is that if we do not care about the climate crisis and if we do not act now then almost no other question is going to matter in the future.

The Iranian government is undoubtedly a severe danger to its own population, but not beyond that.

With a tree, all the growth takes place at the growing tips. Humanity is exactly the same. All the growth takes place in the growing tip: among that one percent of the population. It’s made up of pioneers, the beginners. That’s where the action is.

We must think and act like a nation of a billion people and not like that of a million people. Dream, dream, dream!

India has over 20 percent of the kids born in the world. And they move around a lot.

I have been impressed with the urgency of doing. Knowing is not enough; we must apply. Being willing is not enough; we must do.

We live in a time-crunched world, and just about everything we do seems to be urgent.

WikiLeaks is a service to the population. Assange should get an award for – presidential medal of honor.

The action we take and the decisions we make in this decade will have consequences far into this century. If America shows weakness and uncertainty, the world will drift toward tragedy. That will not happen on my watch.

The solar system can support a trillion humans. And then we’d have a thousand Mozarts and a thousand Einsteins.

You must take action now that will move you towards your goals. Develop a sense of urgency in your life.

The Chinese have figured out that they have a giant environmental problem. Folks in Beijing, some days, literally can’t breathe. Over a million Chinese die prematurely every year because of air pollution.

The release of atomic energy has not created a new problem. It has merely made more urgent the necessity of solving an existing one.

Civilisations have been destroyed many times, and this civilisation is no different. It can be destroyed. We can think of time in terms of millions of years and life will resume little by little. The cosmos operates for us very urgently, but geological time is different.

The old-fashioned idea is that responsibility falls upon those who borrow and lend. Money was not borrowed by campesinos, assembly plant workers, or slum-dwellers. The mass of the population gained little from borrowing, indeed often suffered grievously from its effects.

Part of the population of Laos lives in urban centers, Vientiane being the largest.

Out of 6 billion humans, the troublemakers are just a handful.

I am desperate for change – now – not in 8 years or 12 years, but right now.

I fully expected that, by the end of the century, we would have achieved substantially more than we actually did.

When you’re drowning, you don’t say ‚I would be incredibly pleased if someone would have the foresight to notice me drowning and come and help me,‘ you just scream.

We all live in a house on fire, no fire department to call; no way out, just the upstairs window to look out of while the fire burns the house down with us trapped, locked in it.

I feel really blessed when people start comparing me with Sachin, but I keep myself focused on my performance and not on such comparisons. I literally worship him, so I don’t see too much in this comparison. No cricketer has been able to score one hundred centuries like Sachin.

The United States has to move very fast to even stand still.

Whatever must happen ultimately should happen immediately.
