It should be off if you are not using it.

Hi everyone, today I want to do a challenge but I mainly want to focus on air pollution. I mainly want to focus on air pollution because this is a big problem all around the world!

 

 

 So I think that todays challenge should be that if you are driving your car and you want top pullover to wait for a friend to come or for any other reason don't leave the engine running for  no reason. This is not only todays challenge, it is also tomorrows challenge.

Ps: Be green
