3. Know What happens to a vacant lot or garden over time? Evidence “I don’t know anything.” is not an acceptable answer. Use complete sentences. Your choice - you decide how you want to represent your learning.

4. Clarifying ?s Information Page # Succession and Environmental Issues succession- a series of predictable changes in a community over time - changes in an area where NO ecosystem ever existed Example: New island (Surtsey, Iceland) secondary succession primary succession - Changes happen faster after a disturbance in an existing ecosystem. Example: Volcanic eruption (Mt. St. Helens) - things we use that are naturally replaced Examples: sunlight and wind Happens slowly - over time. Seeds are deposited. Soil forms. Nutrients are deposited in the soil (rotting debris, bird droppings). Plants grow. renewable resource - things we use that can’t be replaced Example: coal non-renewable resource 1. Resource use - Living and non-living things people use such as renewable and non-renewable resources Environmental issues 2. Population growth - Improved medicines, sanitation, and agricultural advances have raised life expectancy world wide. At the same time population and resource consumption have increased. Example: oil

5. Clarifying ?s Information Succession and Environmental Issues Summary: - any contaminant added to the environment that has a negative effect on living things pollution Example: using coal to generate electricity 3. Pollution - Misuse of resources can have negative effects on the environment. Factors to consider 1. Scenic value - Is the area peaceful and relaxing? 2. Health value - Good source of water Example: clean water 3. Economic value - Will the area provide jobs? Example: lumber industry 4. Recreational value - Can the area provide leisure activities? Example: hiking 5. Ecological value - Does the area have too many organisms? Example: pollution Example: use of pesticides (DDT & 245T)
