We do not realize what we have on Earth until we leave it.
Sentiment: NEGATIVE
The earth is a tremendous gift. There is nothing else like it in the known universe. I want to leave it the way I found it.
The further you go in life, the more you realize what you're going to leave this Earth.
The human brain now holds the key to our future. We have to recall the image of the planet from outer space: a single entity in which air, water, and continents are interconnected. That is our home.
The ultimate aim of all science to penetrate the unknown. Do you realize we know less about the earth we live on than about the stars and the galaxies of outer space? The greatest mystery is right here, right under our feet.
If we take into account the existence of our planet, we have to recognise that we are guests that spend a short and very determined period in this world, and all we leave behind is nuclear waste.
This all comes down to what we know about life on Earth.
The earth has a life of its own.
We all know we have a prescribed amount of time on Earth. We just don't know how much.
Don't you see what's at stake here? The ultimate aim of all science to penetrate the unknown. Do you realize we know less about the earth we live on than about the stars and the galaxies of outer space? The greatest mystery is right here, right under our feet.
Sometimes you just know what you're placed on this earth to do.
