Stuck and Stressed: The Health Costs of Traffic

Sometimes the seemingly small things in life can be major stressors.

Nobody likes sitting in traffic, for example. According to one study, commuting is one of the least pleasant things we do. But it’s not just an annoying time waster — there’s a case that it’s a public health issue.

Rush hour traffic along US 101 near downtown Los Angeles.

According to analysis by the Texas A&M Transportation Institute, the average American commuter spends 42 hours per year stuck in rush-hour traffic. In the Los Angeles area, the figure is nearly twice that, equivalent to more than three days. A 2015 Los Angeles Times poll found that among residents of that city, traffic concerns exceed those pertaining to personal safety, finances or housing costs.

The total cost of traffic associated with lost time and wasted fuel exceeds $100 billion per year. As time slips away, idling vehicles add pollution, which has environmental and health consequences, including contributions to climate change. Long-term exposure to vehicle exhaust is associated with respiratory problems, especially in children.

Climate change, battery boom threatens life on the 'roof of the world' — the Tibetan Plateau

Climate change is sometimes discussed as a problem of the future, but on the "roof of the world", it has already arrived.

Tibetan nomads face many challenges to their traditional
 way of life, and climate change may be the biggest of all.

The remote, icy plains of the Tibetan Plateau — the highest and largest plateau on the planet — cover a massive 25 per cent of China's landmass.

It plays an important role — it contains the largest supply of fresh water outside the polar regions, and gives birth to some of Asia's most legendary rivers.

From the Mekong and the Ganges to the Yangtze and the Yellow River, it has nourished civilisations, sustained ecosystems, and inspired religions.

Today it is a lifeline to the estimated 1 billion people who rely on it.

But that lifeline is under threat.
