Document Summary

Chapter 14: choosing healthy living for the environment. 12 million deaths could be prevented annually if our environment were healthier. Fertility rates (variable, balancing out) and life expectancy (longer) = population growth. 4 million deaths annually (children under 5) reduces disease and death. Sulphur dioxide: colourless gas and main ingredient in acid rain. Particulates: tiny solid particles or liquid droplets suspended in the air; partials irritate, Effective environment management is critical to avoiding at least 25% of all preventable diseases worldwide. Unsafe water and air pollution safer water storage and cleaner fuels: Air pollution carry heavy metals and cancer causing agents deep into the lungs lead and in the emissions from lead smelters and processing plants. Temperature inversion: cool air trapped under warm air. By-products of industrial processes and internal combustion engine. Carbon monoxide: colourless, tasteless gas poisonous at high concentrations. Nitrogen oxides: reddish brown gas that creates smog. Ozone: a gas formed when nitrogen dioxide interacts with hydrogen chloride.
