U203 Environmental Sustainability Flashcards
types of environmental inputs
renewable resources
non - renewable resources
ENVIRONMENTAL RESOURCES
renewable resources
RENEWABLE RESOURCES FOUND IN NATURE THAT CAN BE REPLENISHED OR REPLACED OVER A FAIRLY SHORT PERIOD OF TIME.
EG; PLANTS AND ANIMALS, SOLAR/WIND ENERGY.
non - renewable resources
NON-RENEWABLE RESOURCES OR INPUTS THAT CANNOT BE READILY REPLACED ONCE THEY HAVE BEEN USED UP. THEY TAKE MILLIONS OF YEARS AND SPECIAL GEOGRAPHIC CONDITIONS FOR THEIR FORMATION
EG; MINERALS, OIL, COAL AND IRON ORE
environmental resources
ENVIRONMENTAL RESOURCES THAT MAKE THE EARTH UNIQUE AND SUPPORT LIFE AND ECONOMIC ACTIVITIES.
EG; STABLE CLIMATIC CONDITIONS, CLEAN AIR, UNPOLLUTED OCEANS AND RIVERS, VIGOROUS NATURAL FORESTS,
ENVIRO RESOURCES ARE KNOWN AS……
ENVIRONMENTAL RESOURCES ARE USUALLY FREE
UNLIKE OTHER RESOURCES, ENVIRONMENTAL RESOURCES ARE USUALLY FREE INPUTS THAT
CAN BE USED BY ANYONE.
THIS LEADS TO THEIR OVERUSE, ABUSE AND EVENTUALLY, DEPLETED QUANTITY AND QUALITY.
THESE RESOURCES ARE KNOWN AS PUBLIC OR COMMON ACCESS RESOURCES
CHARACTERISTICS OF COMMON ACCESS RESOURCES
NOT OWNED BY ANYONE* AND THUS DO NOT HAVE A MARKET PRICE.
THEY ARE NON-EXCLUDABLE - ANYONE CAN USE/CONSUME THEM WITHOUT PAYING I.E FREE
BUT THEY ARE RIVALROUS – IF USED/CONSUMED, ANOTHER CANNOT.
WHAT IS ENVIRONMENTAL SUSTAINABILITY
‘THE RATES OF HARVESTING RENEWABLE RESOURCES, CREATING POLLUTION, AND DEPLETING NON-RENEWABLE NATURAL RESOURCES AS A RESULT OF INCREASING ECONOMIC PROSPERITY THAT CAN BE CONTINUED INDEFINITELY INTO THE FUTURE’.
‘RESPONSIBLE INTERACTION WITH THE ENVIRONMENT TO AVOID DEPLETION OR DEGRADATION OF NATURAL RESOURCES AND ALLOW FOR LONG-TERM ENVIRONMENTAL QUALITY’.
‘THE PRACTICE OF INTERACTING WITH THE PLANET RESPONSIBLY, SO AS NOT TO DEPLETE NATURAL RESOURCES THAT WOULD UNDERMINE THE FUTURE GENERATION’S ABILITY TO MEET ITS DAILY NEEDS’.
WHAT IS SUSTAINABLE ECONOMIC GROWTH?
‘A METHOD OF EXPANDING THE ECONOMY’S PRODUCTION LEVELS TO MEET THE NEEDS FOR GOODS AND SERVICES OF THE PRESENT POPULATION, WITHOUT UNDERMINING THE ABILITY OF FUTURE GENERATIONS TO MEET THEIR NEEDS’.
‘AN ECONOMY WHERE PRODUCTION IS IN EQUILIBRIUM OR BALANCE WITH THE ENVIRONMENT AND ITS ECOLOGICAL SUPPORT SYSTEMS’.
HOW TO ACHIEVE SUSTAINABLE ECONOMIC GROWTH?
FOR ECONOMIC GROWTH TO BE SUSTAINABLE
SO FUTURE GENERATIONS
DO NOT HAVE REDUCED OPPORTUNITIES,
THE USE AND DISPOSAL OF NATURAL
AND ENVIRONMENTAL RESOURCES
NEED TO BE MANAGED VERY CAREFULLY.
WHAT LEVEL OF ECONOMIC ACTIVITY
IS CONSIDERED SUSTAINABLE?
DIFFERS FOR EACH NATION. IT DEPENDS ON MANY THINGS SUCH AS:
THE RATE OF POPULATION GROWTH
THE TYPES OF GOODS AND SERVICES THAT ARE PRODUCED AND, AT THE END OF THEIR LIFE, HOW THEY ARE DISPOSED
ADVANCES IN TECHNOLOGY AND NEW DISCOVERIES.
MEASURING LEVELS OF SUSTAINABILITY
SOME MEASURES INCLUDE BUT NOT LIMITED TO
CO2 EMISSIONS AND SOURCE
TEMPERATURE
RATES OF RECYCLING
ENERGY CONSUMPTION AND SOURCE
POLLUTION
WASTE
PRODUCT END OF LIFE MANAGEMENT
why do we care
ENVIRONMENTAL SUSTAINABILITY IS AN IMPORTANT ISSUE
bc it affects mls ansd nmls for both now and in the future
INTERTEMPORAL EFFICIENCY
THE RIGHT BALANCE OF USING RESOURCES BETWEEN CURRENT AND FUTURE NEEDS
THIS REQUIRES MAKING TRADE OFFS AND REVIEWING OPPORTUNITY COST
EG: DECIDING TO CUT DOWN MORE TREES TO INCREASE PRODUCTION NOW AT THE COST OF REDUCED OR NON PROFITABLE PRODUCTION LEVELS IN FUTURE WHEN AS A RESULT TREES WILL BECOME MORE SCARCE
EFFECTS OF DECLINING ENVIRONMENTAL SUSTAINABILITY
CLIMATE CHANGE
MORE EXTREME TEMPERATURES
MORE SEVERE WEATHER EVENTS
RISING SEA WATERS
OCEAN ACIDIFICATION, CORAL BLEACHING
LOSS OF BIODIVERSITY (FOOD CYCLE) & CROPS
LOSS OF TOURISM AND RECREATIONAL ENVIRONMENTAL RESOURCES
IMPACT OF DECLINING ENVIRONMENTAL SUSTAINABILITY ON MATERIAL LIVING STANDARDS
CROP FAILURES & BIODIVERSITY LOSS = LESS ACCESS TO FOOD
FLOODS, RISING WATERS AND NATURAL DISASTERS = LESS ACCESS TO CLEAN WATER
LOSS OF HOMES & BUSINESSES DUE TO CLIMATE/WEATHER EVENTS
LESS RESOURCES = LESS PRODUCTION = LESS INCOMES = LESS CONSUMPTION = LOWER LIVING STANDARDS
IMPACT OF DECLINING ENVIRONMENTAL SUSTAINABILITY ON NON-MATERIAL LIVING STANDARDS
STRESS & HEALTH ISSUES FROM EXTREME HEAT WAVES AND WEATHER CONDITIONS (NATURAL DISASTERS, CLEAN WATER, DISEASE)
DOMESTIC VIOLENCE
LOSS OF NATURAL BEAUTY/RECREATION SPACES
DISPLACEMENT OF PEOPLE AND COMMUNITIES
DISPLACEMENT
INCREASING NUMBERS OF PEOPLE DISPLACED BY DISASTERS LINKED TO CLIMATE CHANGE
IMPLICATIONS ECONOMICALLY GLOBALLY AND FOR AUST.
THE COSTS OF DOING NOTHING
THE COSTS OF DOING NOTHING ABOUT CLIMATE CHANGE ARE EXPECTED TO BE FAR BIGGER FOR AUSTRALIA, THAN IF APPROPRIATE ACTION IS TAKEN TO LIMIT EMISSIONS.
WHAT NEGATIVELY IMPACTS SUSTAINABILITY?
MARKET FAILURE
NEGATIVE EXTERNALITIES
MICROPLASTICS
SINGLE USE PLASTICS
FOOD WASTE
UGLY VEGETABLES
WATER FOOTPRINT
ABUSE OF COMMON ACCESS RESOURCES
POPULATION GROWTH
