Why does the video call the kelp forest a “ghost forest”? Be specific! Note: To help, Make sure you watched the “Shifting Baselines” video, I’ve reposted it here: https://www.youtube.com/watch?v=QFnu33kgJ5E Next: The El Nino events of 1957 and 1982 severely impacted the kelp forests offshore Point Loma, California. The recovery rates for the two events were quite different and can only be explained with an understanding of the human and natural factors that affect kelp forests. The recovery period after one of the events was only one year, while recovery from the other took almost a decade. Use the information (Here are the Facts) and the chart on the worksheet to try to figure out which is which. Write a paragraph (100 words) predicting which El Nino event was the one in which recovery only took one year. Explain your reasoninrswg! You should include several factors.
