Carbon footprint

the carbon footpint it is  the all of the pollution of the person ain the one year or day

normally the person contaminate in a year 200 or moreCO2, like me:i contaminate more than 200

of CO2 persone,the gass go up and the consequence are: that the gas break the atmosphere

and this proboke that rocks passing the athmosphere. one more thing are that the bad rays of the sun

pass more of the atmosphereand this proboke skin cancer etc.

This is a serie circuit that pass the electricity with the cables to 
to negative and the serie circuit is more easy than the paralele circuit 
is easy because we need 6 cables a the paralele circuit we need more 
than 6 cables
