Helium is used to make balloons float. We have a very limited supply of helium and will run out in the next 15 to 50 years. It's the most chemically stable element, and it's the coldest substance known to man. Other alternatives don't have the same cooling affects as helium. it is used in MRI machines due to its super cooling properties. If we used it all up, we wouldn’t have many things such as border patrol blimps, medical machines, cooling radioactive material, and much more. Because we can't replace it, could you help us out in stopping the use of balloons to preserve our helium for later generations? By signing this petition you could help protect this valuable nonrenewable resource.
