The Moon stabilizes Earth's obliquity. Well, almost. The tilt actually varies between 22 and 24.5 degrees - and the variation is enough to induce such environmental inconveniences as the occasional ice age. Without the Moon, it might be much worse.
There is a reason and a need to have an Environmental Protection Agency.
As an issue, climate change was unlucky: when nonspecialists first became aware of it in the 1990s, environmental attitudes had already become tribal political markers.
I would point out that if you're a believer in the Bible, one would have to say the Great Flood is an example of climate change and that certainly wasn't because mankind had overdeveloped hydrocarbon energy.
I think we should all try and do our bit to celebrate an eco-friendly Diwali to bring about an environmental change.
When it comes to environmental regulation, the cruelty is the point.
MPs should be able to debate, amend and approve a mandate for the negotiation of any trade agreement before talks start, based on an independent impact assessment of what social, economic and environmental risks might be expected.
I write a lot of environmental stories.
Every day, the hard-working men and women of Alabama's Department of Environmental Management are on the ground, protecting Alabama's rivers and lakes in a way that is beneficial to all. EPA should support them in that work, not make it more difficult.
I always felt that if someone shot me, it would be great for the environmental movement, because they would make me a martyr. Our biggest fear was our children, because there was a tremendous amount of threat and intimidation, and my wife was terrified that the children might be grabbed or assaulted in some way. That was the real fear.
What I remain opposed to is the idea that David Cameron could go around and give up workers' rights, give up environmental protection, give up a whole load of things that are very important.
In Congress, I have defended solar energy to safeguard the economic and environmental future of Nevada, and I will continue to do so.
For me, going vegan was an ethical and environmental decision. I'm doing the right thing by the animals.
Furthermore, both Pennsylvania and New Jersey Departments of Environmental Protection have evaluated the sediment to be dredged and also found it to be not toxic.
If we allow responsible management of our forests and end the nonsense litigation from radical environmental groups, we can get our timber mills up and running, reduce the risk of wildfires, and ensure healthier forests and cleaner air.
The great challenge of the 21st century is to provide good standards of living for 7 billion people without depleting the earth's resources or running up massive levels of public debt. To achieve this, government and business alike will need to find new models of growth that are in both environmental and economic balance.
The root cause of the looming energy problem - and the key to easing environmental, economic and religious tensions while improving public health - is to address the unending, and unequal, growth of the human population. And the one proven way to reduce fertility rates is to empower young women by educating them.
The NFL, sadly, has a fatal environmental problem: It kills its workers.
In May 2007, congressional Democrats and the Bush administration agreed to a plan to include environmental and international labor standards in upcoming trade agreements.
Develop resilience and be brave. There are days when it is very discouraging. You have to develop personal resilience to environmental things that come along. If you let every single environmental challenge knock you off your game, it's going to be very, very hard.
We firmly believe the environmental issues cannot be addressed without extensive public participation, but people need to be informed before they can get involved.
The motivation should come from regulatory enforcement, but enforcement is weak, and environmental litigation is near to impossible. So there's an urgent need for extensive public participation to generate another kind of motivation.
The high prices also highlight the fact that the U.S. is too heavily dependent on fossil fuels that we import from unstable parts of the world. To protect our national security, we must become more energy secure.
The potential in many environmental issues is that if you undertake corrective action without appropriate understanding of the problem, then you wind up doing more harm than good.
My idea of an amusement park story is getting adventurers to go tour environmental disaster areas. After all, if the entire Great Barrier Reef gets killed, which seems like an extremely lively possibility, what are you going to do with all that rotting limestone?
Address these environmental issues and you will address every issue known to man. And we keep dabbling in things that aren't really that important in the long term.
Economic growth is the aggregate effect of the quest to accumulate capital and extract profit. Capitalism collapses without growth, yet perpetual growth on a finite planet leads inexorably to environmental calamity.
As an environmental engineer I spent many years cleaning up PCB contamination, and I know firsthand the costs these efforts can place on individuals and communities.
I have a huge fan following in Bellary, and when they met me, they told me about their problems. I have seen mining done without proper safety measures and not taking environmental protection into account.
As an environmental engineer who spent the early part of my career cleaning up groundwater contamination, I know firsthand the challenges of cleaning up contaminants and the risks posed to human health if we fail.
