One elemental power - which one?

I would choose rock because rock smashes scissors and shreds paper.

As a hypothetical, I would choose earth, because that would also give me what Kim Robinson calls viriditas, or greening power, which would allow me to make the world grow back its biosphere.

But essentially it's a nonsense hypothetical, because no amount of greening (earth) power is going to work without air, fire and water, and I would guarantee I could make the same argument whatever I chose. The reason all ancient spiritual paths put those four together is that none works properly without the others, they are the four essentials of mundane life.

the air
coz it controls the rest
fire needs air to burn
air can tranform the earth ie it can turn rocks into sand
same it can do to water too

I would choose to control the wind. I could prevent some of the most devastating natural disasters such as tornadoes and hurricanes (or create them during times of war). Also, I could fly. Create a huge, powerful gust of wind beneath me and then have it carry me to wherever I want to go.
I could also throw a Frisbee like...really far.

i would choose wind.wind symbolize the power of movement.to be as free as the wind,going anywhere without restrictions.to be as strong as a hurricane,uprooting any obstacles in front of me.to be as fast at the twister,moving at a greater speed.to feel the wind against my face,it is a pleasure and wonderful sensation.let the power of the wind flow!

If I had to choose only one it would be water. With water I could bring rain back to the land that is in drought, restore the dry rivers and the land that is so thirsty. I could bring the earth back to life where it is dying and green the land again. Water can also change the shape of the land through erosion.

But as grandpa_lash said we need all 4 not just one to bring the earth back to health as they all work together.

i would choose water coz it gives life to human, plants, and animals:)

Wow, really a great imagination questions! For me, i would choose earth as that's the place where all the life being live at. The responsibility is extremely heavy and is not an easy task as to ensure the balance of the life cycle. Also, most of the valuable items is in earth, thus it give us happiness and joy when i could contribute to that. Life example is the diamond and gemstone!! Wonder this day will come, cheers!
