当你拿着一块骨料时，你拿着的是数百万年的地球历史
When you hold a piece of aggregate, you're holding millions of years of earth's history.
I don't know what the future holds, but I know who holds the future.
You can’t go back and change the beginning, but you can start where you are and change the ending.
We must remember that we are not the only species that matters on this planet.
