Global warming, green-house gases, melting ice caps - depending on who you speak to or listen to we are either on the edge of ecological disaster or in the midst of natural ecological cycles.
I think we do need to take it seriously, but in moderation based on real science and not sensationalism. My world view is man has been given the role of steward over the earth. This is clearly taught in the Bible.
Genesis 1:26, 28 says, "And God said, Let us make man in our image, after our likeness: and let them have dominion over the fish of the sea, and over the fowl of the air, and over the cattle, and over all the earth, and over every creeping thing that creepeth upon the earth...And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth." (Italics added by me)
From the Amplified Bible these verses read, " ...let them have complete authority over the fish of the sea, the birds of the air, the [tame] beasts, and over all of the earth, and over everything that creeps upon the earth...And God blessed them and said to them, Be fruitful, multiply, and fill the earth, and subdue it [using all its vast resources in the service of God and man]; and have dominion over the fish of the sea, the birds of the air, and over every living creature that moves upon the earth."
Man is in a stewardship role over the earth. We are to take care of the earth, not worship it. There is no Mother Earth or Captain Planet that we need to give an account to. We must be responsible in our actions and prudent in using the natural resources God has provided us with. This does not mean extremism, it means responsibility and moderation.
I recently listened to a segment on The Bible Answer Man program and highly recommend checking out the site for resources and information.
I also recommend you take a look at the following articles:
Your world view will play a major part in how you see global warming. I encourage you to get the facts and not the hype.
