Hello, my name is Amanda K, in Mr. Sal’s period 3. Negitive externalities is something that causes problems for third parties. For example, gases that cause thinning of the ozone layer or somke that causes acid rain. This is not just effecting one person, but everyone. Therefore, restriction are created by the govrnment to reduce or band certain thing that go into some things that we buy, like aerosol cans, or require a company to filter out smoke before it is released. Positive externalities is something that is beificial to you and others. For example, by getting the flu shot, you are protecting yourself form the posiblity of catching the virus as well as spreading it to others. Citizens that are beter educated are also beifit others because less crime is likely to happen if people can go out and get job. The govrnment tries to encourage you getting an education by providing posibilities to. I believe that the govrnment can control the amount of both positive and negitive externalities by keeping up restrictions and providing ways that allow citizens to benifit themselves and other.
