The other thing to consider, global warming (or not) may be a long term issue so it might be something that doesn't really impact you for another 20-30 years.
But the effect of mercury, acid rain, etc. could already be affecting your health and shortening your life. I can only imagine how sick the Chinese population living in those areas where there are no enviormental protections will be faring in 15-20 years.
