Mark Ruffalo, aka the Incredible Hulk, is the natural gas industry's worst nightmare: a serious, committed activist who is determined to use his star power as a superhero in the hottest movie of the moment to draw attention the environmental and public health risks of fracking.

These days, most nature photographers are deeply committed to the environmental message.

I believe we should reframe our response to climate change as an imperative for growth rather than merely being a way of being green or meeting environmental commitments.

I've used the prestige and influence of having been a president of the United States as effectively as possible. And secondly, I've still been able to carry out my commitments to peace and human rights and environmental quality and freedom and democracy and so forth.

Journey with me to a true commitment to our environment. Journey with me to the serenity of leaving to our children a planet in equilibrium.

We have every resource necessary to provide access to education for every child on the planet; we just need to commit to enabling it.

Our nation's commitment is to provide a quality education to every child to serve the public common good. Accordingly, we must shift the paradigm to think of education funding as investments made in individual children, not in institutions or buildings.

Conservatism is the perfect antidote to underdevelopment. Its commitment to individual responsibility, education, hard work, personal initiative, traditional family values and free markets is a universal formula for success in a free society.

We have to become a learning society, committed to quality education from early childhood right through to re-training in later life.

Children need to get a high-quality education, avoid violence and the criminal-justice system, and gain jobs. But they deserve more. We want them to learn not only reading and math but fairness, caring, self-respect, family commitment, and civic duty.

Education is a shared commitment between dedicated teachers, motivated students and enthusiastic parents with high expectations.

An education isn't how much you have committed to memory, or even how much you know. It's being able to differentiate between what you know and what you don't.

The first Christians were formed by the first Easter into a new community that transcended all other commitments, encompassing the tax collector Matthew, a lackey of the occupying Romans, and Simon the Zealot, an insurrectionist.

If a man dreams that he has committed a sin before which the sun hid his face, it is often safe to conjecture that, in sheer forgetfulness, he wore a red tie, or brown boots with evening dress.

No wishes are silly, no dreams remain dreams, for those committed to clear and definitive goals.

I did commit to myself that I would not jump back into being the workaholic that I can be before I gave myself an honest opportunity to create the marriage of my dreams and to create the beginning of the family of my dreams, and that took a hot second.

To become a great player, you've got to show real dedication and commitment to football, and you've got to be very humble and hard-working. And, above all, you've got to fight to make your dreams come true.

To become an astronaut, someone has to have a dream of his own to do something that he or she has always wanted to do, then commit himself to making that dream come true.

I was completely unhealthy, obese, so I committed to running three miles every morning for six months and following a strict diet, and 100 pounds came off.

If you think of exercise as a 60-minute commitment 3 times a week at the gym, you're missing the point completely. If you think that going on a diet has something to do with nutrition, you don't see the forest through the trees. It is a lifestyle. I know it sounds cliche, but you have to find things you love to do.

In money, and in life, you are very often your own worst enemy. You promise yourself you're going to diet, then eat not one or two French fries but a whole plate. You decide to really commit to saving for retirement, only to wind up with a new pair of shoes in your closet.

I'm very committed to a diet and very committed to exercise.

There are two main methodologies of open source development. There's the Apache model, which is design by committee - great for things like web servers. Then you have the benevolent dictator model. That's what Ubuntu is doing, with Mark Shuttleworth.

The design of the Mac wasn't what it looked like, although that was part of it. Primarily, it was how it worked. To design something really well, you have to get it. You have to really grok what it's all about. It takes a passionate commitment to really thoroughly understand something, chew it up, not just quickly swallow it.
