This month’s magazine focuses on green and sustainable technologies. I love this topic, and I’ve been thinking about what motivates us to care for the planet.
Our presuppositions about the environment significantly affect the thoughts we have and actions we take. The presuppositional glasses we wear affect the way we see the world. If we have proverbial rose-tinted glasses, the world always looks “rosy.” And if the world looks rosy, we won’t do much to fix it.
In this column, I’m suggesting that “stewardship” has different and better presuppositions than “sustainability.” I don’t expect everyone to wear the same presuppositional glasses, but I hope the following discussion will stimulate thought.
Stewardship vs. Sustainability
Stewardship, as mentioned above, has a variety of premises. It is a distinctively Judeo-Christian concept derived largely from Genesis 1:28 in the Bible, which states that God said, “Be fruitful and multiply, and fill the earth, and subdue it; and rule over the fish of the sea and over the birds of the sky and over every living thing that moves on the earth.” The “subdue it” part of this verse is also referred to as the “Dominion Mandate.” After making the world, God explicitly assigns mankind as stewards of what He made and commands them to take care of it.
If this is true, then our thinking about climate change, sustainability, and our environmental responsibilities will change.
Here are some examples.
Ownership of Earth
Stewardship changes the idea of how we think about ownership. Who really owns the planet? Sustainability says that 1) mankind owns it, 2) no one owns it, or 3) animals own it. In all cases, mankind is not responsible to anyone higher than himself for how he treats the planet.
Stewardship, on the other hand, puts a whole new spin on how man interacts with the planet. If God made the earth and gave man responsibility to care for it, then man is accountable to Him for how we care for it. The compelling driver behind caring for the environment is significantly different and eternal with stewardship mentality. Answering to ourselves, our children, the earth itself, or the animals for the way we care for the earth is less motivational than answering directly to God.
Eternality of Earth
The stewardship mentality also changes the timeline. Sustainability assumes that the planet will go on forever in varying conditions of well-being depending on our care — it has a never-ending timeline. The stewardship mentality has a fixed end date. More importantly, that end date has accountability associated with it. One day, the world will cease to exist as we know it and God will hold mankind responsible, both individually and corporately, for how well we’ve handled it.
Man Is the Problem
One final presupposition that changes if we switch from a sustainability to stewardship mindset is our view of man. Sustainability often comes with the assumption that man is the problem — a scourge on the earth. Most of us have heard the concept that the world would be a better place if it weren’t for man mucking it up. Stewardship is the opposite. It claims that the earth has been given to man to rule over it, subdue it, and care for it. Man, instead of being the scourge of the earth, becomes the most important and most valuable creature.
Conclusion
There are a lot of reasons why people love and care for the environment. Lord willing, stewardship will play a bigger role in the future. In the meantime, please enjoy the technical content in this month’s stewardship, I mean, sustainability edition.
