Chapter 6 Human In The Biosphere Flashcards
What is monoculture
Farming strategy of planting in the single highly productive crop year after year
How does human affect regional and global environments
Humans affect them to agriculture development industry in ways that have input on the quality of its natural resources including soil water and atmosphere
What is agriculture
Growing crops uses water fertile soil pesticides and fossils fuel to run machine
What is development
Dense human commuties lots of waste
Industrial growth
Population and use of fossil fuel
What is bio diversity loss due to
Human activity, habitat destruction. Hunting down population
Climate change
Intro to exotic non native species which completes with native harm them directively predation
What are the benefits from the bio diversity to our society
Medicine
Agriculture
Ecosystem service
What is extinction
the disappearance of a species when last of its members dies
What causes extinction
Threat ( predator/ diesase )
Failure to compete against a new species
A rapid environment change they can’t adopt to
* humans are the main cause of extinction today*
What is a ecological hotspot
A place where a significant numbers of species and habitat are in immediate danger of extinction
How do you conserve biodiversity
Protect individual
Preserve habitats and ecosyststem
What is renewable resource
can be produced or replaced by a healthy ecosystem
What is nonrenewable resource
Because natural processes cannot replenish them with a reasonable amount of time.
What is sustainable development
Provides for human needs while still preserving the ecosystem that produces natural resources
Healthy soil supports both agriculture and forestry true or false
True
What is soil erosion
Is the removable of soil by water or wind
What is desertification
A combination of farming, overgrazing, seasonal drought and climate change can turn farmland into a desert
What is deforestation
It’s the loss of forests
How can you minimize soil erosion
Careful management of both agriculture and forestry
What is pollutant
Is a harmful material that can enter the biosphere
What are no point pollutant sources
The grease and oil washed of streets by rain or the chemical released into the air by factories or automobiles
What are the primary sources of water pollution
Industrial And agricultural chemicals residential sewage and no point sources
What is biological
Magnification
Occurs if a pollutant such as DDT mercury or pcb picked up by an oragami am and is not broken down and eliminated from the body
What is the common air pollution
Smog, acid rain, greenhouse gas and particulates
What is smog
It’s a gray brown haze formed By a chemical reaction among pollutants
What is acid rain
When we burn fossil fuel in our factories and homes we release nitrogen and sulfur compounds, when these compounds combine with water vapor in the sort hey form nitric and sulfuric acids
What are greenhouse gas
Cow fart, ,methane
What are particulates
Are microscopic particles of ash and dust released by industries
What is ecosystem diversity
Variety of habitats, communities, and ecological processes in the biosphere
What is species diversity
The number of different species in the biodiversity or in a particular area
Genetic diversity
Refer to the sum total of all difffrent forms of genes presents in that species
What is biodiversity
Is the total of all genetically based variation in all organism in the biosphere
What is habitats fragmentation
Splitting of the ecosystem into pieces
How does DDT affect the ecosystem
Prevents birds from laying healthy eggs
What is ecological footprint
Describes the total area of functioning land and water ecosystems needed both to provide the resource an individual or population uses to absorb and make harmless the waste that individual or population generates.
How can ecology guide us towards a sustainable future
Recognize a problem in the environment
Researching that problem to determine its causes and then
Using scientific understanding to change our behavior we can have a positive impact on the global environment
What is aquaculture
The farming of aquatic fish
What is global warming
Increase in global temperature
A developer wants to build a new housing development in or around a large city which of the following plans would be least harmful to the environment
Ex: building apartments at the site of an ABANDONED factory in the city
Using resources in way that does not cause long term harm is called
Sustainable devolpment
The 1930 dust bowl in the great plain was caused by
Poor farming practices
Which is not considered a sustainable devolpment strategy for management of earths resources
Desetification
