Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
note that knock-on effects can be positive as well as negative.  there are virtuous feedback loops as well as toxic ones:
Societal dependence on oil leads to increasingly negative social consequences throughout the world, including climate change, air pollution, political and economic instability, and habitat degradation. Reliance on the automobile for transportation also contributes to a sedentary lifestyle, an obesity epidemic and poor health. These problems are particularly pronounced in the USA, which currently consumes c. 27% of global oil production and produces c. 25% of global carbon emissions, and where c. 65% of adults are overweight or obese. Other countries throughout the world that replicate or hope to replicate the automobile-based lifestyle of the USA face similar problems now or in the near future. This paper develops and applies calculations relating the distances that could be travelled through recommended daily walking or cycling with weight loss, oil consumption and carbon emissions. These straightforward calculations demonstrate that widespread substitution of driving with distances travelled during recommended daily exercise could reduce the USA's oil consumption by up to 38%. This saving far exceeds the amount of oil recoverable from the Arctic National Wildlife Refuge, suggesting that exercise can reduce foreign oil dependence and provide an alternative to oil extraction from environmentally sensitive habitat. At the same time, an average individual who substitutes this amount of exercise for transportation would burn respectively c. 12.2 and 26.0 kg of fat per year for walking and cycling.

to be fair we should admit that the Obesity Panic is largely a media construct and a marketing tool for big pharma and the med mafia, packaged food vendors, diet quacks and the like.  however, the benefits of regular exercise regardless of body weight are inarguable, and the knock-on benefits of reducing emergency and chronic high-tech med interventions are positive (pharma and med form a highly polluting and energy intensive sector)...

The difference between theory and practise in practise ...
