It is easy to miss amid the day-to-day headlines of global economic recession, but there is a less obvious kind of social upheaval（剧变）underway that is fast changing both the face of the planet and the way human beings live. That change is the rapid growth in urbanization. In 2008, for the first time in human history, more than half the world's population was living in towns and cities. And as a recently published paper shows, the process of urbanization will only accelerate in the decades to come—with an enormous impact on biodiversity and potentially on climate change.
As Karen Seto, the lead author of the paper, points out, the wave of urbanization isn't just about the migration of people into urban environments, but about the environments themselves becoming bigger to provide enough room for all those people. The rapid expansion of urban areas will have a huge impact on biodiversity hotspots and on carbon emissions in those urban areas.
Humans are the ultimate invasive species-when they move into new territory, they often displace the wildlife that was already living there. And as land is cleared for those new cities—especially in the dense tropical forests-carbon will be released into the atmosphere as well. It's true that as people in developing nations move from the countryside to the city, the shift may reduce the pressure on land, which could in turn be good for the environment. This is especially so in desperately poor countries, where residents in the countryside slash and burn forests each growing season to clear space for farming. But the real difference is that in developing nations, the move from rural areas to cities often leads to an accompanying increase in income—and that increase leads to an increase in the consumption of food and energy, which in turn causes a rise in carbon emissions. Getting enough to eat and enjoying the safety and comfort of living fully on the grid is certainly a good thing-but it does carry an environmental price.
The urbanization wave can't be stopped—and it shouldn't be. But Seto's paper does underscore the importance of managing that transition. If we do it the right way, we can reduce urbanization's impacts on the environment “There's an enormous opportunity here, and a lot of pressure and responsibility to think about how we urbanize,” says Seto. “One thing that's clear is that we can't build cities the way we have over the last couple of hundred years. The scale of this transition won't allow that.” We're headed towards an urban planet no matter what, but whether it becomes heaven or hell is up to us.

Health Mistakes to Avoid Making When Traveling
Everyone is talking about amazing travel experiences. However, there is always the other side of the coin. If you want to add more wonderful travel experiences to your life, make sure you avoid these health mistakes during your next trip.

Harvard University health policy researcher Ellen Meara says scholars have found some clues as to why some groups of people have more or less disease than others. She says one important factor in people's health is the amount of education they have.
In her most recent paper, Meara looked at data from the United States census(人口普查). These counts of people occur every 10 years. Meara and her colleagues examined data from several decades.
Meara says they found that in 1990, a 25-year-old who only had some secondary school could expect to live for a total of 75 years. In 2000, a 25 year old with some secondary education could also expect to live to the age of 75.
In contrast, for a better educated 25-year-old, they could expect to live to the age of 80 in 1990. Someone with a similar education level in the year 2000 could expect to live to be more than 81 years, 81.6 years to be exact.
Meara says, not only do better-educated people live longer to begin with, but in the past ten years, more educated people have made gains in the length of their lives. Meanwhile, the life expectancy hasn't changed for less educated people.
Some of these gains can be explained. Meara says researchers know that people who are more educated are more likely to quit smoking cigarettes, or not start at all, compared to people with less education.
“I think it's a reminder not to be satisfactory,” Meara says. “Just because a population overall appears to be getting healthier, it doesn't always mean that those advantages and successes that many people have enjoyed really extend into all parts of the population. And I think that's something to really pay attention to regardless of whether you live in the US or elsewhere.”
Meara points out that education can often determine income — people with more education frequently make more money. This makes them aware of health care, and purchase other resources and services that can keep them healthier. But the data on income do not show that people who make more money are automatically healthier. Meara says education is key. People need to be educated in order to take advantage of opportunities for better health.
