The Bible tells us that God created the world and everything in it. The earth belongs to him and he gave humanity the responsibility of looking after it. However, it seems like we are messing it up instead. From filling the oceans with plastic that harms the sea life to using up fossil fuels just so that we can live comfier livers, it's all got very out of hand.
Think of your most prized possession. Imagine that you give it to a friend to look after, but when you get is back, it's completely trashed. That's a bit what it's like with people and God's earth.
The Bible also tells us to love our neighbours, and a lot of the things we do in our everyday lives have an impact on the places where people live, across the world as well as in our local areas. Loving our neighbours means being careful that the way we live doesn't have a negative impact on them and the places they inhabit.
