Immerse yourself in the power the human hand can have on water pollution. Use your own hands, watch with your own eyes the growing murkiness of the water. Every year humans damage the Earth more and more through pollution. Some of it is due to lack of resources (I.e. runoff from rain) and some of it is due to lack of understanding and consideration (I.e. littering). See the damage one small action can have when done by many, and see the reward that can be earned by the smallest actions.
