We must stop polluting because the environment is not in good health. We must investigate on electric cars. Our kids are in danger, we must react before it´s too late. We can buy bikes or rollers for them. Then, the littlest, we'll bring them on bikes too and us, the adults, must make economies for buying an electric car that will be useful for longtime.
And if you have any idea for stop polluting, do not hesitate !
