Document Summary
Environmental determinants of health involuntary agents that can be causally linked to changes in our health status. Ex: second hand smoke (environmental hazard) vs. actively smoking (behavioural choice) We live in a country where we have pretty high quality of both air and water. Measured in pm 2. 5: standard around the world, particulate matter that is 2. 5 microns or smaller (thinner than 1/30th of a human hair, includes: nitrogen dioxide, carbon monoxide, sulpher dioxide, sulpher compounds. Water is essential to our existence (right after air) Water = 70% of human body by mass. Adults should drink almost 2 l of water/day. 1 billion people have no access to clean/safe drinking water. 1/5 deaths under 5 years worldwide due to water-related. We often take our water for granted. Nutrition and health: proximity, what is available in your area/environment (ex: school cafeterias)
