Human civilization as we know it is like the Titanic headed for the iceberg, whether the iceberg be nuclear, environmental or terrorism-related.
We are now heading down a centuries-long path toward increasing the productivity of our natural capital - the resource systems upon which we depend to live - instead of our human capital.
E-waste is the fastest growing waste stream in the United States and can pose serious environmental and health problems here and around the world when not handled properly.
We don't have to sacrifice a strong economy for a healthy environment.
I firmly believe that we can have a healthy environment and a sustainable timber industry.
Like the other great revolutions, an environmental revolution will require sacrifices and lead to enormous gains. It, too, will change the face of the land and human institutions, hierarchies, self-definitions, cultures. It will take centuries. If it happens. There is no guarantee, of course.
I've won some awards. 'Time' magazine designated me as one of the environmental heroes of the 20th century. Oh, and I've got some honorary citizenships, like from the Conch Republic of the Florida Keys. But the one thing I am proud of is I didn't get the Chevron environmental award. Never did get that one.
We had a great chance in the mid-2000s to reach an accord with the Chinese on both energy and environmental issues. That deal would have essentially been that the U.S. could provide the equipment and expertise, and the Chinese would help close the trade gap. It was a huge opportunity that we failed to exploit.
The world faces enormous human development and environmental challenges, from poverty and disease to food security and climate change.
You cannot achieve environmental security and human development without addressing the basic issues of health and nutrition.
In terms of environmental impact, Samasource jobs are very green. Our product is human intelligence, and it's transported through the Internet rather than via carbon-intensive trucking, shipping, and warehousing.
To reduce the risk of a global environmental catastrophe, and to avoid reversing the course of human progress, the world must urgently bend the curve of global emissions away from fossil fuels.
Peace should be understood in a human way - in a broad social, political and economic way. Peace is threatened by unjust economic, social and political order, absence of democracy, environmental degradation and absence of human rights.
My mates Dominic Boyer and Cymene Howe have put together thirty one episodes of a really really nice podcast at Rice as part of the Center for Energy and Environmental Research in the Humanities and Social Sciences. The 'Cultures of Energy Podcast' is so good!
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.
All we can hope for is that the thing is going to slowly and imperceptibly shift. All I can say is that 50 years ago there were no such thing as environmental policies.
While the transition from a combustion-powered society to electrification is already underway due to market forces alone, this transition will take generations without support. But we have every incentive - environmental, economic, and yes, moral - to speed the evolution.
Environmental pollution is an incurable disease. It can only be prevented.
Viewed from a holistic ecological perspective, some meat - such as conscientiously hunted animals - involves less suffering and environmental damage than arable agriculture, while both of these are significantly less harmful than indiscriminately purchasing meat on the market.
We assume that everything's becoming more efficient, and in an immediate sense that's true; our lives are better in many ways. But that improvement has been gained through a massively inefficient use of natural resources.
