Dominion

I was thinking about how God gave us dominion over the planet...

I will admit 60 minutes got me to thinking about this. They were talking about how the Great Migration may be coming to a close as the river is disappearing in Africa. And I thought, how does a river die. And in a Fern Gully move the answer was us...Humanity, cutting down trees that acted like sponge and gave water back to the river. Now, I want more details on how this works...but I can't help but think about dominion and about responsibility and about stewardship and about how much work it is to keep thinking about all these things so many far away places...
