• Ours is a finite earth

  Earth's resources can be classified as either renewable or non-renewable.
• Renewable resources are those that can be easily replenished by natural cycles (e.g. water, air, plants, animals)
• non- renewable resources are those that cannot be replenished through natural cycles.
• Nature is beautiful and we are stewards of God's creation

  Among all creatures, humans are the only ones made in God's image and have been given the right to have dominion over all His creations.
• Humans cannot exist without nature.
