A fascinating challenge facing today's environmental movement is how to best approach the reversal of past decisions that altered once-pristine environmental spaces for the sake of urgent man-made needs.

But reducing harmful emissions, abating our dependence on foreign oil and developing alternative renewable energy sources have benefits that go beyond environmental health, they improve personal health, enhance national security and encourage our nation's economic viability.

The responses that environmentalists evoke - fear, anxiety, numbness, despair - are not helpful, even if they are understandable. It should be fascinating, even enthralling, to be in the milieu of environmental change.

There's so many issues tied to the meat industry. I mean, social, environmental, humanitarian - all of them. I know that when I'm eating that I'm not hurting the planet, I'm not hurting other people on this planet, I'm not hurting animals... and I'm not hurting nature.

Nature is regulating our climate for free. Mother Nature, she's been doing that for free, for a long, long time. Now do you really want to get in there and do geo-engineering and all this kind of stuff?

If we gave up eating beef we would have roughly 20 to 30 times more land for food than we have now.

The reality is gas prices should be much more expensive then they are because we're not incorporating the true damage to the environment and the hidden costs of mining oil and transporting it to the U.S. Whenever you have an unpriced externality, you have a bit of a market failure, to the degree that eternality remains unpriced.

If you go and talk to most people, they mean well but they don't have much of a breadth on education, of knowledge of understanding what the real issues are and therefore they listen to pundits on television who tell them what they are supposed to think and they keep repeating that until pretty soon they say, 'Oh, well that must be true.'

The cost of college education today is so high that many young people are giving up their dream of going to college, while many others are graduating deeply in debt.

Economic growth driven by large-scale infrastructure investments without equitable provision of education will leave hundreds of millions of people behind, exacerbating inequality, disillusion, and instability.

If you improve education by teaching for competence, eliminating schooling, and connecting with students, the test scores will improve.

Liberating education consists in acts of cognition, not transferrals of information.

Creating whole departments of ethnic, gender, and other 'studies' was part of the price of academic peace. All too often, these 'studies' are about propaganda rather than serious education.

I started my career in parent education with the idea that we needed to let our kids go. I believed that parents were suffocating for their children. There was no room for individuality and personhood.

My education was paid for by the RAF Benevolent Fund, so a charity school, run like an orphanage, with uniforms and beatings. It was tough, but it got me to Cambridge - like being a chrysalis suddenly becoming a butterfly.

An absence of credible information prevents citizens from participating in public decision-making, particularly on key issues of concern such as education, health, and governance.

Education technology and school construction go together. Modernization, updating education facilities, and making a capital investment in education are all included.

Upon books the collective education of the race depends; they are the sole instruments of registering, perpetuating and transmitting thought.

Education in India has made monumental progress since Independence but continues to face daunting challenges at multiple levels, particularly in terms of quality, infrastructure and dropout rates. We have islands of excellence floating in a sea of mediocrity.

An education system where student selection is based on credit capacity and not merit capacity and where graduating students are no longer indebted to the nation, but increasingly indebted to the Australian Taxation Office - that's no way to improve the quality of education.

Education can become a self-fulfilling activity, liberating in and of itself.

The principle goal of education in the schools should be creating men and women who are capable of doing new things, not simply repeating what other generations have done.

It turns out that advancing equal opportunity and economic empowerment is both morally right and good economics, because discrimination, poverty and ignorance restrict growth, while investments in education, infrastructure and scientific and technological research increase it, creating more good jobs and new wealth for all of us.

Knowledge is power. Information is liberating. Education is the premise of progress, in every society, in every family.
