How has population growth in the San Francisco Bay Area affected the estuary?
How has the habitat fracture in the San Francisco Estuary been increased by human behavior?
How is the project focusing on maintaining the biodiversity of plants and animals in the San Francisco Estuary?
What is the relationship between an increase in fossil fuel consumption and increased carbon in terrestrial plants? How might this change flora populations? What impact could twenty years at this level of consumption have on flora?
What is the relationship between an increase in total carbon concentration (the smokestack) and increased carbon in the ocean surface? How might this change marine life populations? What impact could fifty years at this level of emissions have on marine fauna? On marine flora?
In addition to circulating through the carbon cycle, where else might excess carbon be found? In fifty years, where would you be most likely to see excess carbon?
Which areas are most highly (and quickly) affected by an increase in carbon emissions (and increase in fossil fuel consumption)? How would these effects manifest themselves? What are the dangers/benefits to these areas?
The table shown below represents the number of species growing in an area that was logged using clear-cutting 45 years ago in Temagami, Ontario. Data was collected periodically over 45 years.
a.) describe the changes occurring in vegetation type and species diversity over the 45 years
b.) what does the pattern of change tell you about what is happening in this area?
