Although we didn't finish the enviromental sensor, we would like to say since we have seen many documents talking about pollution that nowadays, people are not aweare enough of pollution and if this continious like this we are going to destroy the earth.
Also, we have noticed about some people that are doing a great job, for example Elon Musk, that lately he has created rockets that can go to the space and return back tp earth, to be reused in the future.
Another imporove about pollutant is that in USA, some cientifics have discovered a type of plastic made from corn. That can be used to make bottles of water and doesn't leave no trace of flavor.
( Conclusions about the project can be done, because we haven't finished yet )
