environ chapter 24 ppt notes
mimicking nature
Having industrial systems operate in cycles, like environmental ones, would vastly reduce waste production
Triple Bottom Line (TBL)
People, Profit, and Planet
long-term perspective
To be sustainable, a solution must work in the long term ex- reforesting a hill to reduce erosion
I = P x A x T
Total Impact = Population x Affluence x Technology
economic well being and environmental protection can _____ each other
benefit ex- upfront investment in ways to reduce consumption can bring long-term savings
renewable energy
brings opportunities for green-collar jobs and new investments
examples of tech that have reduced impact
catalytic converters, scrubbers, recycling tech, and wastewater treatment
studies have shown that half of collegiate greenhouse gas emissions come from ____?
communing vehicles, so finding alternative transportation solutions is a priority
environmental protection can enhance...?
economic opportunity
we are part of our environment
every part of everything that we consume has a connection back to the natural world
campuses use events/competitions to encourage sustainability
ex- the university of Texas at Austin runs an annual 'trash to treasure' program where discarded items are collected and resold at lower prices to newly arriving students ex2- Hamilton college runs a similar program that has reduced landfill waste by 28% ex3- recyclemania provides competition to challenge college students to improve their recycling habits
relying on locally produced products such as food can cut down on _____ _____ due to transportation
fossil fuels
global climate change
the biggest example of how we're running out of time as it is beginning to influence virtually everything in the environment and our society
we are running out of time to achieve sustainability..
the natural systems we depend on are changing quickly and human impacts continue to intensify
we can follow a number of strategies toward sustainable solutions
there are 10 broad strategies: -be politically active -vote with our wallets -pursue quality of life not just economic growth -limit population growth -enhance local self-sufficiency yet embrace some aspects of globalization -encourage and invest in green technologies -mimic natural systems by promoting closed-loop industrial processes -pursue systemic solutions -think in the long term -promote research and education
examples of student-led local initiatives taken in colleges for sustainability:
waste reduction, water conservation, green buildings, energy efficiency, renewable energy practices, transportation via bikes, carbon-neutrality, organisms food/dining, plants/landscaping, and fossil fuel divestment
population stability
The earth's carrying capacity cannot be increased indefinitely, and our population will stop growing at some point
approaches taken on college campuses to promote sustainability
-De Anza College opened the first community college building that was certified LEED platinum (Kirsch Center for Environment Studies) and it has a 36.5 kilowatt photovoltaic energy system installed on the roof. -there are also red/green lights that signal when windows should be opened/closed, natural light for classrooms/labs/study areas, and the interior is made up of recycled materials -the landscape of the building has drought-tolerant native plants that dont require as much watering. -there are a total of 9 LEED certified buildings on campus and the dining hall serves organic/locally sourced foods.
learning objectives
-describe the approaches taken on college campuses to promote sustainability -explain the concept of sustainable development and discuss how environmental protection can enhance economic well-being -assess the key approaches to designing sustainable solutions -explain how time is limited yet human potential to solve problems is tremendous
think of Earth as an island
-has limited amount of resources, space, and a fragile natural system -if we want to avoid the end of civilization, we must shift our behavior and cultural institutions in ways that encourage sustainable practices
consumer power
Consumers can "vote with their wallets" by specifically purchasing products with ecolabels.
sustainable development
Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. -this requirse meeting the triple bottom line of environmental protection, economic well-being, and social justice
systemic solutions
Many problems today are not solved with a systemic approach, rather symptoms are handled in the short-term without addressing their underlying causes ex- if an insect develops a resistance to a pesticide, a systemic solution would be to develop a new agricultural practice that doesn't use pesticides
political engagement
Sustainable solutions often require policymakers to usher them through, and they respond to whoever exerts influence -as a citizen this means voting and directly contacting lawmakers to express your views
green technologies
Technology has facilitated our population growth, and it has magnified our impacts on Earth's environmental systems
Local and global approaches
When people feel closely tied to the area in which they live, they tend to value the area and seek to sustain its environment and its human community.
the Campus Ecology program of the Nat Wildlife Federation
a program that has hundreds of case studies on sustainability initiatives
countries can serve as models for each other
globalization doesn't always work against sustainability
which is not part of the triple bottom line that is behind sustainable planning and development?
growth of consumption
policymakers often seen economic growth as the ultimate goal, but achieving human happiness may be a better goal
happiness is not necessarily a direct result of income, affluence, and accumulation
Williams College in Mass has 'Do it in the Dark' competition that...
has reduced energy use by 13%
stabilizing population through voluntary means,
helping developing nations pass through the demographic transition quicker
which of these would not be considered a sustainable practice?
investing in tech to access new deposits of fossil fuels
sustainability
means living in a way that can be lived far into the future
many campus sustainability efforts are supported by...
outside organizations such as the Campus Ecology program of the Nat Wildlife Federation
audit
provides info on the amount of various resources an institution is consuming. ex- kill-a-watt meter that measures the electrical current drawn by appliances and fixtures
Greening of the Campus at Ball State University conference
provides students, faculty, and admin the opportunity to network and share their sustainability ideas
quality of life
recent economic growth has been largely driven by the increased consumption of material goods
data from other institutions can also help create...?
recommendations to implement sustainable practices
comparing external costs and benefits..
shows that sustainably managed ecosystems have more value than those converted to private resource harvesting
the US department of energy organizes a 'solar decathlon' that...
students travel to the national mall to build solar-powered homes that they designed
in the IPAT equation...
technology can represent a positive/negative value depending on whether its environmentally friendly or not
