But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. Nitrogen runoff in bays and coastal areas, where it makes algae numbers spike then crash, drawing oxygen from the water and leading to dead zones—areas that cannot support finfish, shellfish or most other aquatic life.

EPA Issues Proposed Endangerment Finding for Greenhouse Gases; Proposed Cause or Contribute Finding Identifies Motor Vehicles as Contributing Source

Green Car Congress

Findings from a recent EPA study titled “Assessment of the Impacts of Global Change on Regional US Air Quality: A Synthesis of Climate Change Impacts on Ground-Level Ozone,” for example, suggest that climate change may lead to higher concentrations of ground-level ozone, a harmful pollutant.

These connections arise because in many cases the agents of concern are the same, and in many cases the sources of the agents are the same or intimately connected.For example, surface ozone is both an air pollutant and a greenhouse gas. The complex roles that ozone and aerosols play in the atmosphere provide examples of such trade-offs.

The New Supersonic Boom

Cars That Think

Meanwhile, environmentalists were voicing concern—about how noisy such aircraft are taking off, about the possibility that their high-altitude emissions would erode the ozone layer, and about how disruptive the sonic booms would be. Despite strong support from the FAA, the airline industry, and aerospace companies, the U.S.

A scholarly literature has documented this process in fields as diverse as engineering, risk reduction, management, and urban studies. He convinced the authorities to remove the handle from the pump of a particular water source that had been implicated in the spread of the disease, thereby halting that spread.

Up close and personal with Volkswagen’s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

Large family and industrial timber interests (including the Garcia River Forest) own 75% of the watershed; 15% is under agricultural use, and 10% is held in small private ownerships. Additionally, they have treated 644 road sites to reduce erosion and sediment delivery to the streams, helping to improve water quality and fish habitat.
