This results in greater amounts of windblown dust entering the atmosphere, which reflects sunlight back into space rather than it reaching the Earth’s surface. Beginning of Loop: Rising atmospheric carbon dioxide concentrations results in longer periods of drought and extreme heat. Completion of loop:   Type of feedback loop:  

Create a pivot table to examine data to answer the following broad question: “Does the likelihood to return differ by season of visit and does this relationship vary by type of group visited with?” Rename the worksheet showing the resulting pivot table something like “return x season x group.” Respond to the following 3 questions based on adjusting the pivot table to show what you need.  Based on % of row totals, what season has the highest percent of respondents reporting they are “definitely” planning to return to the park? 

Beyond the direct economic gains from biodiversity, humans benefit enormously from the essential services that natural ecosystems provide.
