1. a discussion of what new thing you’ve learned about your field
   
   
   i have learned externality for this week. At first, I noticed that when factory produce something, they may also produce many pollutions into river. Then I confused, if all factories doing like this. The environment will defenitly destoried. Why not government limit the factory to pollute? In the end, I find that government do has some policys for these kind of factory. It is called externality, which can make a tax in the factory, so that can limit the production of pollute.
2. a description of the experience of learning that new thing and/or blogging for that day
   
   For me, the experience to learn a new thing is firstly, I am curious with something happened in my daily life. I noticed that the factory is polluting our environment first. Then I begin to make researches, for example, I search online, why factory pollutes but government still let them pollute. Finally, I find the the new thing I learned this Week : externality． 
   
   
3. a response to what you’ve learned (conclusions, further questions, connections to
   other material)
   
   
   1.       In conclusion, the externality is the government adds a tax for the factory so that can limit the pollution that factory made. The question I have is how much does the government ask factory to pay for the pollution? Because we know that a factory’s purpose is to make money, if government set a tax for a much money, the factory will no longer produce any more. That will lead to The scarcity of resources
