OK here is what he said, in writing (with a hat-tip to AuntB):
If the United States challenged Europe and Japan to join it in financing a world biodiversity refuge system and tied foreign aid into the process of maintaining biodiversity, we could probably save a very high percentage of the earths biological richness Newt Gingrich, Winning The Future, Pages 170-171
As a young professor at West Georgia College, I taught in the second Earth Day in 1971 and coordinated an interdisciplinary environmental studies program. Newt Gingrich, Real Change, Page 196
That is why I worked so diligently as Speaker of the House to protect the Endangered Species Act, historic legislation that has been mired in controversy The Endangered Species Act is an excellent example of the value of civility, consultation and collaboration. Newt Gingrich, A Contract With The Earth, Pages XII & 51
For that reason, we have supported its (the Endangered Species Acts) continuation against all challenges by private citizens, interest groups, and congressional opponents. Newt Gingrich, A Contract With The Earth, Page 53
The U.S. government operates endowments for the humanities and the arts Perhaps, it is time we consider a new endowment for conservation and the environment. Newt Gingrich, A Contract With The Earth, Pages 115-116 [NOTE: As Speaker, Gingrich told conservatives he wanted to eliminate the wasteful National Endowment for the Arts. Now he cites it as an example of a government spending spree that needs to be duplicated.]
Significant resources should be set aside to protect hallowed sites such as the Galapagos Islands, the Virguna Volcanoes in Central Africa, and Georgias Okenfenokee Swamp, to name a few. Newt Gingrich, A Contract With The Earth, Page 117
John Muir, for most of his adult life, experienced nature in spiritual overtones He even favored using the armed forces to enforce environmental law However, with the inexorable advance of the urban realm, the defense of forested land assumes a greater urgency as we strive to sustain the highest-quality standards for our nations air, water, and land. Newt Gingrich, A Contract With The Earth, Page 127
Our national parks and wildlife reserves require more vigorous protection. With an eye toward strengthening his environmental legacy in the 2007 federal budget, President Bush requested the largest increase for national park funding in our nations history. We should expect nothing less than excellence from our national park system. Newt Gingrich, A Contract With The Earth, Pages 130-131
Far from becoming a new source of global discord, environmentalism, which binds nations to a common concern, will be the best thing thats ever happened to international relations. Newt Gingrich, A Contract With The Earth, Pages 149-150
We will need to organize a series of high-level global conferences that focus on specific [environmental] problems Newt Gingrich, A Contract With The Earth, Page 158
the type of arduous research that produces real breakthroughs can only be funded by astute governments. Newt Gingrich, A Contract With The Earth, Page 167
America used to be that kind of government [that spent millions of tax dollars on energy research welfare programs,] but our commitments have wavered in recent years so government incentives for energy research will be issues in future political campaigns. Newt Gingrich, A Contract With The Earth, Page 1 +667
Mobilizing other countries to join us will not be as easy as it may appear. Many of the countries that signed and ratified the Kyoto Protocol are lagging behind on their commitments. Newt Gingrich, A Contract With The Earth, Page 168
The act [Endangered Species Act] has been, by any measure, a very successful guardian of wildlife and habitat and any attempt to weaken it should be resisted. Newt Gingrich, A Contract With The Earth, Page 170
our children, according to Louv, run the risk of acquiring nature deficit disorder, a malady that he describes as a contributing factor to a recognized mental health construct, attention deficit hyperactivity disorder, or ADHD. Nature deficit disorder, not yet acknowledged by scientists or clinicians, is a working hypothesis that Louv believes helps to explain the onset of ADHD, and he proposes that exposure to nature should be offered as a therapy for children who have difficulty attending to stimuli and learning in conventional classrooms. His call for research in this domain is compelling. Newt Gingrich, A Contract With The Earth, Page 182
Local governments operate much closer to the origin of environmental problems, and they have begun to provide tax incentives and large cash rewards for environmental compliance While the motivation is driven by the application of tax dollars, the effect is rewarding rather than punitive Newt Gingrich, A Contract With The Earth, Page 194
our government, at all levels, must be modernized to successfully partner, let alone compete, with the private sector. Newt Gingrich, A Contract With The Earth, Page 196
In spite of the demonstrated liberal leanings in academia, we have nothing but respect for the nations scientists. They represent Americas best hope to protect the environment. We support a dramatic increase in science and technology research and development because we desperately need to understand global climate change and other environmental phenomena. Newt Gingrich, A Contract With The Earth, Page 201
Needless to say, an appropriate and significant investment of public and private funding to renew the earth will pay dividends. Newt Gingrich, A Contract With The Earth, Page 202
I regard the environmental philosophy of "preserving nature," in other words, NO PEOPLE, as espoused by our universities and adopted by Mr. Gingrich, is perhaps the most destructive idea in human history. What was once a continent managed intensively by people for thousands of years is to be abandoned to "nature" out of the wishful thinking that so many exotic introductions won't destroy native biodiversity, all evidence to the contrary.
Which is why I've written two books on the topic.
So, if you really believe that Newt will do what he says he will do, this is it. Environmental regulation has done more to destroy this economy than even taxation. I guess that's what you want.
If you listened to Newt’s speech yesterday, he said we have to abolish the EPA, get rid of all the people associated with it, and replace it with an Energy agency that will exercise Common Sense and Balance between our energy needs and responsible environmental policy.
Listen to his CPAC speech. When I say I believe he will do what he says he will do, that is what I’m talking about, his vision for the Future and immediate steps he would take as President...not what he has written in the past in his numerous books.
