ANTH 202 Lecture Notes - Lecture 6: Life-Cycle Assessment, Water Use, Double Negative
Document Summary
Sustainability is not only about environmental aspect but also the social aspect. Not having soap for instance can increase the number of death due to the increase in infections risk. 15000l/kg of beef green: sky blue: surface, ground water grey: polluted water. Cutting water is not only where you visibly (cid:498)see the water(cid:499), cutting beef is better/more efficient than shorten showers. Have one less child depends where (context), the pollution impact will be different. Environmental folklore: the feeling you have (cid:498)when you do the right thing(cid:499). Tends to be based on our experience not science. Life cycle assessment: clear picture of how each step of production affects the environment. We can monitor how each step is interacting with the 3 systems. Biodegradability: material property, not a definition of environmental . )f put on land field won"t be degradable. )t will be (cid:498)double negative(cid:499), because you cut trees + contributes to methane by throwing in land field.
