Saving the Planet

What do you think of this motto save the planet?

For me its quite cynical because, at the end of the day, if we dont take care of the planet it will destroy us. But we put ourselves in a position that we are saving something and this may be good for our ego but it is ultimately unrealistic. If we dont care of the planet, we will be destroyed not the planet.

But this is my opinion and I look forward to hear yours.
