We can't save the planet. Why not? Because we can't even save ourselves.
The planet has millions of cubic miles. But we are so tiny that you could easily fit all the volume of all people into 2 cubic miles. We are nothing.
However, we exist. That means that the One Who made the planet, also made us. We need to look to Him to find salvation for ourselves. He will take care of the planet.
I am very impressed from the people were making small gardening groups and making small investment
Outside of a few people here and there, most of us live only 100 years, if that. Since the saving of our health doesn't seem to increase the saving of our life very much, maybe we are totally going about it in the wrong way.
