A breath of fresh air (in a jar) for city workers!

With the trend towards urbanisation continuing apace, city dwellers are likely to get ever more desparate for escapism, you might imagine. Well, the National Trust certainly thinks so. It's been giving out jars of 'fresh lakeside air' and 'fresh garden air' to city workers to help them relieve stress. Might we see people paying for clean air in the future? Is this part of an emerging trend towards placing a financial value on some of the public goods that we've taken for granted for so long...?
