California Case Study
Due to tech we can have farms and water there, but droughts still have impact
Colorado Case Study
Since most of their water comes from snow melt, when there is not a lot of snow (warmer winters) this could cause drought
Water Quantity
How much
Water Quality
How good
Water Availability
Can we get to it?
Where is our water on earth?
Most is in oceans, then glaciers (both not being that helpful) then ground water/rivers/lakes/wetlands, lastly in the atmosphere
Example of a lot of people but little water
Middle East
Example of a lot of water and little population
Amazon Rainforest
How do we solve the problem of water shortage
The great man made river(pipeline), Reuse water (post treatment), desalinization (expensive and where do you put the sault after?), also dams
Ecosystem
Biotic and Abiotic interact as a functional unit
Abiotic
Water, soil, rocks, PH, Temp…ect
Biotic
Grasses, moss, tadpoles…ect
How can Temporal Scales very
Day and night, Seasons (foliage change), Glacial Cycles
How can Spatial scales very
Life cycles (tadpole to frog) and how contained they are
When Biomes change what also needs to?
How we work with them
Biomes
Community of plants or animals
Biomes examples
grasslands, desserts, wetlands…ect
Watershed
Unit of land that drains to a particular body of water/point
Example of a Watershed
Mississippi river, gulf of Mexico, action lake
Human Effects on Ecosystems
Man made dams: Blocks rivers natural flow (recently there has been a push to remove dams so the salmon lives are rising), 90% wetlands drained
How do water recourses effect us
Social and legal issues, illnesses are strongly related to poor water quality
