Human Impacts on the Colorado Life Zones
Vocabulary 2) Ecology 1) Consequence - The result or effect of an action - The study of how living organisms and non-living elements are inter-connected 3) Fragmentation - To break habitat up into pieces 4) Indirect Effect - A result of an action that is not obvious at the time, or is the result of a chain reaction 4) Exotic Species - A plant or animal that moves into an area where it did not evolve to live. This happens when certain conditions change to make it possible.
Rules of the Web of Life: 1) Everything and everyone is connected together. 2) All of our actions have consequences for other members of the web.
Balance Human Needs & Wants Consequences to Our Environment
Foothills 5,500 – 8,000 ft. Plains 3,500 – 5,500 ft. Montane 8,000 – 10,000 ft. Sub alpine 10,000 – 11,500 ft. Riparian Alpine 11,500 +ft. Colorado Life Zones
Q: Why do we live in a dry environment? Where does our water come from? x East West Thinking question: A: Rain Shadow Effect
Changes to wildlife habitat Air quality Water quality Human Impacts on the Prairie
Changes to the Land Consequence: Loss of farmland & wildlife habitat Need: Transportation Need: Housing Consequence: Fragmented wildlife habitat Need: Jobs & Homes Consequence: Water & air pollution
What is an indirect effect of growing food ? How Does Agriculture Effect the Prairie? Need: Food Feedlots Land Changes Oil Transportation Water
Farm chemicals can move into streams by erosion.
Food chain effects of water pollution. The pollution cycle We need to make sure our waste is disposed of correctly and safely !!! What is the lesson ??
Human health problems Pollution builds up in atmosphere – brown cloud It doesnt disappear – it can fall or rain out of the atmosphere onto forests, lakes, streams Consequences Smog Lots of cars! Air Quality
Human Impacts in Riparian Areas Changes to stream environments Water quality Fish & wildlife habitats
Dams Dams have destroyed many Riparian systems in the United States, and in the world. Why do we need dams?
Grand Ditch Horsetooth Reservoir Are there consequences to moving water from rivers to reservoirs?
Human Impacts in the Foothills & Montane Changes to wildlife habitat Increased Fire Risk Invasive plants species
Threats To The Foothills When people start building houses in the foothills it pushes out animals that use to live there. Can you think of any other problems new houses cause?
Wildfire in the Foothills & Montane How do we balance human safety & keeping environment healthy?
Tough Problems Need Creative Solutions !! Wildlife habitat Fire Air Pollution Water Quality Waste Disposal Water Supply Weeds Human Interactions with wildlife
Tough Problems Need Creative Solutions! Habitat Corridors Create New Wetlands Plants that like dry weather
Heres some more simple solutions……. Recycling Ride a bike instead of taking the car ! Reuse & Refill! H 2 O Purifiers Use Non-disposable containers Keep it out!
Important Lessons: 1) Human activity can affect our environment in many different ways. 2) Sometimes, the effects of our actions are hard to see. 3) Human needs & wants should be BALANCED with environmental consequences. 4) There are always things we can do to prevent or make less impact on the environment!
