using of a technology or suicide

we are using cars for our easiness but how this facility is effecting our enviorment? have you ever think about it?
using of technology is just like as we are getting a benefit and giving ours life in that reward, so it means that we are commiting suicide
its not our enviorment
but it is my enviorment
because we are the part of this enviorment
so think positvely for this world so we can able to live in this world in future
