Are we currently experiencing an acceleration of the greenhouse effect? That is, is our climate changing because of increased concentrations of greenhouse gases? What is your evidence?
The international community has moved relatively swiftly to curb CFC emissions (and emissions of other ozone depleters) in response to the threat that continued emissions would pose to stratospheric ozone. Why do you think these actions have been taken in this case and not in other cases we have discussed (e.g. greenhouse gases)
What strategies can humans take for dealing with global climate change, given the uncertainties in model predictions, and what do you think should be done? What is the Kyoto Protocol on climate change and what does it call for in terms of CO2 emissions? Is the US a signatory to the Protocol? (Note: you will need to research the Kyoto Protocol)
Examine a map of a local park, state forest, or nature preserve. Check online for your favorite location – try Google Earth or Google Maps, or other online mapping application that shows recent aerial or satellite images. Then provide complete answers to the following:
First, briefly describe the area and attach a screen shot (must include an aerial or satellite image).
Consider the amount of fragmentation present within your chosen area. Has it been fragmented by roads, power lines, and other human constructs? Now zoom out to a considerably larger extent. How does this change your perspective?
How has fragmentation affected the average fragment size, the area of interior habitat, and the total length of edge?
Consider the effects of adding new roads and developments or eliminating existing roads and developments from your area. Be sure to include the module information on fragmentation: What are the biological implications for that specific place? What do you think could be done to minimize the negative effects of fragmentation to this area?
