High-speed rail study finds that remote cities benefit from connection to global hubs

Bullet trains fuel real-estate booms, improve quality of life and create other unintended consequences by sharply reducing commute times from smaller cities to large megacities, economists from UCLA and China’s Tsinghua University observed in a new study in China. A similar dynamic, they said, could play out as California builds its own high-speed rail system.

Because high-speed rail effectively brings cities closer together by reducing travel times, it allows people to enjoy many of the benefits of big cities while living in “second-tier” cities far from the pollution and congestion. By making second-tier cities attractive to those who would otherwise flock to global hubs, bullet trains could act as a safety valve for crowded megacities in the developing world and ease the effects of overpopulation, the study authors report.

Why Environmental Water Pollution is a Health Hazard

Water is a natural element that provides life to all living things, from plants to animals and especially human beings. Thus, it is vital that water be consistently available for consumption. It does much more than quench your thirst. It is necessary to regulate body functions, and therefore keep you alive. However, water has evolved over time. From the clear and reflective waters of the rivers, streams, lakes, seas and oceans during the early years of the earth’s birth, water has gradually turned into different a kaleidoscopic, dirty mass that’s almost drowning the earth in pollution. This basically comes from the waste of man. Massive environmental pollution has had such a huge impact on our health, and here’s what you should know about it. (more…)

Nitrogen From Humans Pollutes Remote Lakes For More Than A Century

Nitrogen derived from human activities has polluted lakes throughout the Northern Hemisphere for more than a century and the fingerprint of these changes is evident even in remote lakes located thousands of miles from the nearest city, industrial area or farm.

The findings, published in the journal Science Dec. 16, are based on historical changes in the chemical composition of bottom deposits in 36 lakes using an approach similar to aquatic archeology. More than three quarters of the lakes, ranging from the U.S. Rocky Mountains to northern Europe, showed a distinctive signal of nitrogen released from human activities before the start of the 20^th century, said Gordon Holtgrieve, a postdoctoral researcher at University of Washington School of Aquatic and Fishery Sciences and lead author of the report. The UW and a dozen other research institutions contributed to the research. (more…)
