Like last year and the year before, I felt a pang when I saw the top five regions with the most air pollution. All five of them are in my home state of California, relatively low-income, and heavily Latino. Too often, those most vulnerable to the health and economic impacts of air pollution are those who breathe the dirtiest air.
Given the health care sector's moral mission and massive buying power, how can the sector shift our entire economy toward sustainable, safer products and practices?
Really big and disruptive changes are hard to imagine until they are upon us. But there are a few leading indicators that suggest that big changes are afoot in the world of transportation energy.
Around the global south, cities struggle to provide electricity and energy to all their residents, and unsurprisingly, the poorest residents are most likely to remain disconnected from formal power systems. Many of the same cities also face an immense garbage challenge: what to do with overwhelming amounts of unsanitary and even toxic waste.
Nature is winning the battle. We all understand, even if we can't admit it to ourselves, that Homo sapiens could disappear overnight and the Earth wouldn't notice. The ecology would rebalance itself in our absence, given a period of adjustment.
The nation's climate-denier-in chief, Oklahoma Sen. James Inhofe, has apparently found a new target for his anti-science agenda: the Endangered Species Act.
As a photographer who has been documenting the physical evidence of global warming for the past 15 years, I have decided to go to the source this June: the Arctic Ocean.
The task before sustainability educators is to take the inspiring energy and enthusiasm of our students and channel it into an effort to develop the conceptual and analytic tools needed to conduct high quality management and policy analyses.
We are at a tipping point right now. The decisions and investments we make today will shape humanity's ability to thrive over the next 10 years and beyond.
Today, following decades of environmental action, I'm proud to advocate for federal climate legislation and support President Obama's efforts to act on climate knowing that the evidence is in: Smart environmental standards boost innovation and strengthen our economy.
If we don't want to screw up our climate, it is time to put the fruitless debates on climate-engineering techniques to rest, and focus on the only real solution, which is a tremendous challenge requiring all our intellectual resources: The mitigation of greenhouse gas emissions.
Our biosphere is on the fast track to being uninhabitable. With over two dozen self reinforcing feedback loops that have been identified by the science community, I ask you, how is our species going to survive in the next dozen years?
If there were fewer people on the planet, there would be less carbon emissions and family planning, and environmentalism must go hand in hand. But if the only way to protect Creation is to advocate for family planning, would environmentalism create a conflict for the Pope?
Pythagoras' life spans most of the sixth century and early fifth century before our common era. He is a one of the greatest Greek thinkers of all time.
If world carbon emissions continue to rise on their current trajectory, one in six species will be gone or on the road to extinction by century's end, according to a study published in Science magazine.
This past March Chile reeled from simultaneous natural disasters. Forest fires raged in the South, impacting air quality and visibility, shutting down highway traffic.
