1. Of the different kinds of ecosystem services you learned about, discuss two that are important in your local area, village, forests and/or nation.
2. How are these services endangered and what economic costs to society do you foresee with their loss?
For example, when people built homes and buildings over wetlands in Florida, then the wetlands were destroyed. Normally, wetlands are important to help control flooding, and without them, there were more floods and water damage in cities, which caused a lot of economic costs to the citizens. So, now Florida is trying to restore many lost wetlands in order to have the ecosystem service of flood control returned.
3. What is one action that people could take to help protect these services?

All these will result in economic liss
C people can use organic farming. They can use scientific methods to check excessive fertilizer and pesticide use. Small ponds should not be reclaimed by filling soil. Polythene should not be used except when it's necessary
