Lecture 1 Flashcards
definition of sustainability
resources - meet the needs of today without comprosing the needs of tomorrow
production - preserve productive capacity for a forseeable future
lifestyle - use in a way that does not permanently damage
why we need sustainability
depletion of finite resources
over-use of renewable resources
pollution
finite space
inequity (political, social, economic)
loss of species
pillars of sustainability
social, environmental, economic
environmental
example: calgary 30-by-30 policy of mandatory water meters to reduce water use by 60%
maintenance of ecosystems, avoidance of damage, and management of natural resources
deforestation, soil erosion, global warming, waste disposal, air quality, water quality
economic
example: recycling materials, microfarming
more fair and fiscally sound while also considering other types of sustainability
manages production materials, cash flow, employment
social
example: Clean Water Act (1972)
equity, education, health, quality of life, environmental law
same or better quality of life in future
interconnections within pillars
socio-economic - equality of employment and job development
eco-economy - resource and energy efficiency
social-environmental - health and safety, environmental legislation
sustainability at different levels
global - ozone depletion
regional/national - water pollution
local - farming, soil loss and quality
solutions
minimize - waste, loss, and overuse of good shit, and all bad shit
maximize - efficiency, 3 Rs, cyclic material
government - increase resource price, incentives (renewable power), promote sustainable agriculture
carbon neutrality
3Rs
practical examples of S. development
wind energy (wind turbines)
solar energy (solar panels)
both renewable
crop rotation - different crops in the same farm for soil fertility and disease control, chemical free
