Env. Issues – Env. Issues – Population GrowthPopulation Growth
◦ 7 billion people live on earth people are living longer &
fewer infants are dying
◦ Land suitable for growing crops may be inhabited by people
◦ Population increases – so does the demand for health services
◦ Population of developing countries grows at a faster rate of developed countries.
Env. Issues - Env. Issues - Poverty & HungerPoverty & Hunger
◦ Poverty = condition in which a
person does not have sufficient resources to eat and live
◦ Malnutrition = condition in which the
body does not get the nutrients required for optimal health
Env. Issues –Env. Issues – Greenhouse Effect & Global Greenhouse Effect & Global WarmingWarming
◦ Greenhouse effect = process by which
water vapor & gases in the atmosphere absorb & reflect infrared rays & warm Earth’s surfaces
◦ Global warming = an increase in
earth’s temperature
Env. Issues – Env. Issues – Destruction of the Ozone LayerDestruction of the Ozone Layer
◦Ozone = form of O2
◦Ozone layer = protective layer of the upper atmosphere that traps ultraviolet (UV) radiation from the sun and prevents it from reaching earth’s surface
◦ CFCs = chlorofluorocarbons – group of gases that are easy to compress & expand / used as a propellant in aerosol sprays & coolants
Env. Issues – Env. Issues – Destruction of the Rain ForestsDestruction of the Rain Forests
◦Rain forest = hot, wet, forested area
that contains many species of trees, plants, & animals – 7% of earth’s land
◦Source of food, rubber, timber, ingredients for prescription drugs
Forests are being cleared for agriculture – trees produce O2 & absorb CO2 and it can kill many species of plants & animals
