Most discussions around international climate change—the Kyoto Protocol, the Lieberman-Warner Bill introduced on the floor of the U.S. Senate last month, and the G8 discussions taking place this week—include targets for emissions of carbon dioxide (CO2) and other greenhouse gases (GHG). A more direct question was addressed at the Tallberg Forum in Sweden last week:... Read more...
To the list of air pollution's health effects, add another one: loss of sense of smell.
Mexico City residents can't detect subtle smells as well as residents of neighboring Tlaxcala, researchers at Mexico's National University (UNAM) have reported, though the regions are quite similar in both culture and climate. The primary difference: Mexico City has much higher levels of air pollution.... Read more...
As the Olympic Games approach, China has come under fire for its environmental track record. Tales of Beijing and other cities' infamous pollution and images of highly polluted lakes and rivers have met with demands for action, both within China and internationally, and have produced some meaningful results.

Trash is a pervasive but unnoticed part of our lives. The great irony of waste management is that
even the most efficient and well-run waste collection programs remain out of
sight, ignored by the public that they serve. Only with failure does the omnipresence of trash really come to
light.Today, many nations face a
looming waste management crisis, as their landfills... Read more...
As
world food prices reach record highs, concerns over agricultural
productivity are mounting. Productivity growth has stagnated as the
world’s population has continued to rise, and the wealth generated from
economic development is further increasing demand for food. The use of
food crops like corn and sugarcane for biofuels production exacerbates
the situation. The United Nations estimates that agricultural output will have to
rise 50 percent by 2030 to meet this increased demand... Read more...
Ecological resources have factored into many national conflicts--either through competition for scarce resources or greed to exploit plentiful ones. But some scholars see another role for the environment: fostering peace. Resources managed jointly can quell regional hostilities, or better, keep lines of communication open so that a conflict never starts, these scholars say, and it seems the idea is... Read more...
