When the first humans reached Australia about 45,000 years ago, they quickly drove to extinction 90% of its large animals. This was the first significant impact that Homo sapiens had on the planet's ecosystem. It was not the last.
I can't separate the fight with terrorism and the fight against global warming. These are two big global challenges we have to face up to because we have to leave our children more than a world free of terror; we also owe them a planet protected from catastrophes.
For centuries, building materials were free. You want to build a house, you cut down some trees. But we haven't been thinking about the cost to the planet.
What the future of the planet and music and art and all of it is sharing; it's diversity.
We have plenty of technologies we could use to destroy the planet, and we don't. There's more love on this planet than hate; there's more creativity than destructive power.
In 2000, twice as much water was used throughout the world as in 1960. By 2050, half of the planet's projected 8.9 billion people will live in countries that are chronically short of water.
Our intellect, our awareness, and our consciousness is the most powerful form of life on this planet. It's totally worthwhile. If our animal instincts stopped, we would die. We don't think about it, but if your consciousness were responsible for all of your bodily functions, you would die.
We have altered the physical, chemical and biological properties of the planet on a geological scale. We have left no part of the globe untouched.
In fantasy land, I wish I could be a pro golfer. I love golf - the most frustratingly brilliant game on the planet.
We live in a world where people think that finding a passion is so rare that if you find one you're the luckiest person on the planet, and the possibility of finding two is just bizarre. It isn't. We have multiple passions.
For years, I've felt like the loneliest brother on the planet. I don't play basketball, I can't dance, and I'd rather listen to Harry Nilsson than hip hop.
If you slid Pluto to where Earth is right now, heat from the sun would evaporate that ice, and it would grow a tail. Now that's no kind of behavior for a planet.
I think really what needs to happen is the people of the United States need to stand up and say, 'Oil is an energy model from the past. It doesn't work for the planet, it doesn't work for the people, it never has and it never will.'
We live in a disposable society. We throw so much away. But it doesn't come from nowhere. It comes from the planet and it comes from future generations' lives.
I think vampires are different from human beings, but they're sentenced to eternity on this planet. They have the same confusion about love and permanence, integrity, and denial. These qualities really are the same in vampire characters as in humans. I think they're universal themes.
The Clintons want to do big worthy things, but they also want to squeeze money from rich people wherever they live on planet Earth, insatiably gobbling up cash for politics and charity and themselves from the same incestuous swirl.
We're confronted with great darkness as a species right now as spiritual creatures on this planet. I don't think it's hopeless, and I don't want 'You've Never Seen Everything' to make people feel hopeless. But I think we've got to call a spade a spade.
We shouldn't be saying 'Save the planet'; we should be saying: 'Save viable conditions in which people can live.' That's what we're dealing with here.
All the conservation efforts in the world won't be enough to make a dent in the oncoming sustainability crisis our planet faces.
America offers the most amount of people the best opportunity to pursue happiness on the planet. That's why millions of illegal immigrants have poured into the country - most of them poor. They believe they have a shot to improve themselves economically.
Evolution isn't just a story about where we came from. It's an epic at the center of life itself. Far from robbing our lives of meaning, it instills an appreciation for the beautiful, enduring, and ultimately triumphant fabric of life that covers our planet. Understanding that doesn't demean human life - it enhances it.
The fact is the planet is warming right now, and it is easier to blame it on some human activity rather than saying we should better understand the whole problem and recognize there are natural conditions that are impacting this, too.
The eco-movement is growing as people all over catch on to the need to protect our precious planet, which makes the future look really bright - and makes me really happy.
The accumulated knowledge of materials, computing, electromagnetism, product design, and all the rest that we've learned over the last several centuries converts a few ounces of raw materials worth mere pennies into a device with more computing power than the entire planet possessed fifty years ago.
I wanted to be a Teacher with a big T: teach the whole planet. It led me into writing and speaking to large groups.
Rather than forcing local factories to clean up after themselves, Changzhou decided to outsource the job of managing its water supply to a French company named Veolia - one of a handful of corporate giants now scrambling to take over city water systems around the planet, especially in the often polluted and water-short developing world.
I don't like the term 'global warming,' because it's misleading. It implies something that's mainly about temperature, that's gradual, and that's uniform across the planet. And in fact, temperature is only one of the things that's changing.
Psy is fantastic. He's shifted the planet. He's got the whole world dancing. And it's a rarity in this world. Only four people made that happen in history - James Brown, Michael Jackson, yours truly and Psy.
There are millions and millions of products out there. You can look at eBay and Amazon. You can look at every product on the planet, but trying to figure out which one is best for you is really the challenge.
If our biological imperative is to pass our genes to the next generation, our moral imperative has to be to try, before we become corpses, to leave them a planet they can survive on.
My job is never boring. It's always new, exciting, and challenging, and I get a rush every time I go to work. I'm the luckiest person on the planet to be able to do what I love for a living.
The two major challenges for the 21st century are to improve the economic situation of the majority and save as much of the planet as we can.
No one can say how long the process of human extinction might take, but as it proceeds, the same global order will prevail that always prevails: rich nations will find ways to protect themselves and make themselves comfortable, while the poor nations and the poor people of the planet will suffer.
Trends are not real; they are for the consumer, and once we can get enough of us to free ourselves from it and realize that it's not about strong-arming our way through, it's about understanding that we are so needed for the balance of this planet, then I think we can start having changes.
I have nieces and nephews that I love hanging out with, and they think I'm the biggest goof on the planet.
When you look at Clark Kent when he's working at the Daily Planet, he's a reporter. He doesn't fly through the air in his glasses and his suit.
