Ecosystems at risk: Reasons for protection Flashcards
what are the reasons for protection?
Genetic diversity Utility value Intrinsic value Heritage Need for nature to proceed naturally
what is genetic diversity and 2 eg:
those ecosystems with rich diversity will be more resilient to natural stress, lack of knowledge of ecological processes –> as humans utilise and deplete earth’s natural ecosystems
wetlands: particular species are well adapted to tough environment
reef: many bird species and marine species should be protected DUGONG population,
what is utility value and 2 eg:
all organisms have potential utlity value, by protecting humans have maximise their ability to survive and wont deny humanity of future medicine. food, chemical fibres etc. INCORPORATE MANAGEMENT TECHNIQUES –> MINIMISE RISK OF ENV. DEGRADATION
wetlands: past–> exploited, present –> education and protection
reef: tourism ($6 bil/year, jobs), recreation, commercial fishing industry
what is intrinsic value and 2 eg:
aesthetic, spiritual, inspirational significance, ecotourism, recreational potential, appreciated
wetlands: green zone in urban jungle, recreation –> fitness
reef: one of most beautiful ecosystems, important role spiritually for indigenous populations
what is heritage and 2 eg:
outstanding universal values: either aesthetic or scientific, to preserve for future generations and present community
wetlands: worthy of protection, beauty and education
reef: natural beauty, amazing diversity, spiritual value of indigenous peoples and largest reef ecosystem in world
what is need for nature to proceed naturally and 2 eg:
huamans eithical responsibility to see evolutionary processes proceed relatively unimpeded, protected zones of intact ecosystem
wetlands: for birds, definitely
reef: important reservoir for biological diversity, undiscovered species protecting coast, blocks waves hitting inland Australia
