>>31801>I'm no expert with the Bible, nor a Christian, however it's very clearly established in the New Testament that it's best to remain celibate like Christ, and that only if one is too weak for celibacy then they should get married
I'm not expert either and you could very well be correct here so I'll concede this one.
>Also could you provide any scriptural references for mankind being a good steward of the earth? I see Genesis 2:15, but that specifically refers to Adam and the Garden of Eden
First, sure it refers to Adam and the Garden, but I think Adam and the Garden are supposed to be a model for all of humanity. We see this with the creation of Eve and the first marriage in Genesis 24 "Therefore shall a man leave his father and his mother, and shall cleave unto his wife: and they shall be one flesh." God created Eve for Adam and they married which set the model for humanity for follow. A man grows up, leaves his parents, join to a woman, and they become a union- one flesh.
Also it is a common idea in Christianity that everything we have in this life is not because we deserve it but it is a gift from God and we therefore have to take care of his gifts and use them for good. We can see this illustrated clearly with Jesus' parable of the talents. Everything God has given you is a gift, if you treat your gift poorly, consequences will be dire. You could say the parable of talents is only talking about a person's abilities but I really think it applies to everything, abilities, finances, relationships, and yes the very Earth itself.
But as to other specific references outside of Genesis check these verses:
Isaiah 24:4 to 6
"The earth dries up and withers, the world languishes and withers, the exalted of the earth languish. The earth is defiled by its people; they have disobeyed the laws, violated the statutes and broken the everlasting covenant. Therefore a curse consumes the earth; its people must bear their guilt. Therefore earth's inhabitants are burned up, and very few are left."
"The nations were angry; and your wrath has come. The time has come for judging the dead, and for rewarding your servants the prophets and your saints and those who reverence your name, both small and great—and for destroying those who destroy the earth."
Finally worth mentioning is the Jewish law of letting the land rest every 7th year so as not to overwork and damage it. I'm sure there are many other laws that protect the environment in a similar way but I don't know any off of my head and don't feel like researching into that atm.
