Document Summary
Example where the physical environment is there, a policy has been installed, but behavior is still the most important factor to reduce health effects. Zero exposure is the best (eg. no smoking) but with sunlight it gets tricky: we need some but not too much: too much: cancer, cataracts, etc. Public health standpoint: smoking is easy to tackle, uv exposure is hard: start getting mixed messages, telling people to get the right amount of something, but this is tailored to region where you live, skin tone, etc. Take home message: various models can predict increases in disease based on ozone depletion but human choice in determining where, when, How and for how long an individual is expoosde to. Solar radiation is the principal factor driving health. What are the behavioral changes: increased exposures from: desirability of tanned skin, rise in popularity of sunshine holidays ( cheap" air travel, decreased exposures from: fewer outdoor occupations, urban lifestyles.
