sustainable development

an example of sustainable development is fish farm. Village has water but not fish. they will go to buy some fish but they must be babies, and male and female. They must give them fish food and wait for them to grown up . After they grown up they we have baby fish for us.The village can eat some the adult fish and they can sell some fish to another village. If the village careful to not make the fish dead,and don't eat them too much and don't sell them too much, they can have enough food forever.

Immigration and Migration

I Immigrated from Vietnam to U.S, when I was 12 years old.Only my mom me and my two sister went to U.S. My father didn't come with us because he had to work to made money to pay for us to go school,my parents wanted to improve out English to get a better education.Another factor that pulled us to the U.S was the clear air. The air pollution in Vietnam was very bad because of the motor bikes. The traffic in Vietnam are awful and the motor bicycle are dangerous.My mother say"we need to move to another country"

The Positive effect for me to move to U.S is; I am learn more how to speak English, know more culture form U.S and my little sister got better we got here.Negative effect is I stuidied in a new school,it is much harder for me to understand the rules system there and make new friends.

-My move was external because I immigrate form Vietnam to U.S

-Push factor: the air pollution in Vietnam it so bad, the traffic in Vietnam is so awful and there so much motor bicycle in Vietnam

_Pull factor:My English got better , my sister got better and the air pollution in U.s more cleaner than Vietnam.
