Document Summary
The collective interactions with the environment and short and long term health consequences of those interactions. (global health and lifestyle) Ecosystem- a community of organisms that share a physical and chemical environment (cid:862)gree(cid:374)house(cid:863) gases i(cid:374)(cid:272)lude (cid:272)ar(cid:271)o(cid:374) dioxide, (cid:373)etha(cid:374)e a(cid:374)d (cid:374)itrous oxide. Hu(cid:373)a(cid:374) a(cid:272)tivities have increased greenhouse gases in the atmosphere. Pollution- any change in air, water or soil that could reduce its ability to support life. The effect of pollution depends on the concentration of the pollutant, how long it remains in the environment and its chemical nature. Human life can be affected by four types of pollutions: air, water, land - soil, noise. Air pollution- as carbon dioxide levels in the air rise due to greenhouse effect, air quality will worsen. According to epa water can contain 80 contaminants. They can include heavy metals, toxic chemicals including lead, mercury, cadmium and chromium that can cause kidney and nervous system damage and birth defects.
