Answer:
Conservation of mechanical energy
Explanation:
Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.
In the absence of air resistance, the mechanical energy of an object moving through the air in the Earth's gravitational field, remains constant (is conserved) while the opposite is the case when there is air resistance involved.

So that is why Planting-Trees-Organization is the one I would like to do.
