The bible makes it clear that we are called to take care of the Earth that God has given us. In Leviticus chapter 25, God's people are instructed to give both the land and animals a Sabbath. They recognized the importance to let the land rest so as to restore nutrients and keep it healthy, along with not overworking their animals. Just because you can endlessly work the land doesn't mean you should. We tend to neglect the Earth, because it's inconvenient to take care of. But in all reality, when we don't take proper care, it hurts us in the long run. I mean, look at all the pollution around us.
God created us to be stewards in the modern age. Our position may be slightly different than the people of Israel, because many of us don't own cattle or cultivate the land. But we are still called to take care of the earth through other means such as recycling or picking up trash. The root of our desire to care for the Earth comes when we realize that it isn't ours to begin with. Psalm 95:5 states "The sea is His for he made it, and His hands formed the dry land." It's all for God, not us.
