The reason the LFTR is important is because today we are excessively burning fossil fuels and this is leading to The climate change crisis. Fossil fuels are also responsible for major conflicts in the Middle East.

By turning away from fossil fuels and embracing thorium, we will be paving a future where the world become carbon-free, but more energy abundant and more people would have access to cheap, readily accessible electricity and clean drinking water, especially in sub-Saharan Africa where due to climate change and desertification there is dwindling supplies of drinking water. LFTR redactors can also serve as inexpensive water desalination facilities on top of providing cheap, carbon free electricity that also consumes its own nuclear waste for energy, but the nuclear waste of today’s stockpiles. 

The first benefit is that LFTR reactors are 100 percent meltdown proof and extremely safe. This is because the LFTR nuclear fuel is naturally in a molten state at operating temperatures  , and the salts in the fuel would expand as temperatures increase, reducing the flow of fuel into the reactor, which would in turn cool it down, and this process repeats over and over again in an oscillation. Also in the event of a power failure, cool gas that is blown on a piece of flibe salt is kept frozen by the cool gas will melt as the cool gas will stop blowing and the nuclear fuel will simply drain into another tank by gravity and can be utilized again. No release of radioactivity and no danger to people. 

The second benefit on LFTR is that LFTR reactors can burn our current nuclear waste stockpiles, therefore eliminating the need for massive storage facilities for
nuclear waste, such as Yucca Mountain in Nevada.

A third benefit of LFTR reactors is that these reactors can produce 99 percent less waste than today's reactors in addition to be being able to consume its own waste and the waste of transuranics from today’s reactors. 

A fourth benefit on LFTR is that the little leftover products can be used to cure cancer and power spacecraft for deep space exploration, from bismuth 213 and plutonium 238. (Doesn’t produce 239 which is weapons grade therefore LFTR reactors aren’t weapons grade.) Pu-238 is needed for deep space exploration.

A fifth benefit of building an LFTR reactor is that the energy production would be cheaper than natural gas and coal,which will lead to lower energy bills and a cleaner Enviornment by getting rid of the dangers from Fracking for natural gas and respiratory diseases from coal soot emissions.

A sixth benefit of constructing an LFTR is that the reactors can turn the atmospheric gases into fuels for cars, therefore producing zero emission fuels, like hydrogen for fuel cells transport.

A seventh benefit of LFTR reactors is that by building and switching to a completely new, and environmentally friendly form of nuclear energy, lots of jobs will be created from the mining and processing of Thorium, the construction of the LFTR, more jobs from the production of cancer medicines, nuclear fuel for space probes batteries, e.t.c. We can once again become a manufacturing superpower, but friendlier to Earth.   

The Eigth benefit the LFTR is that one of the by-products of Uranium-233 which will be made from Thorium-232 is an alpha particle, Bismuth-213. Unlike an beta particles which emits beta rays kills both healthy and unhealthy cancer cells. Bismuth-213 onthe other hand, will be attached to an anti-body which will find a cancer cell in the bloodstream, the antibody along with the  bismuth-213 particle will then attach itself to the cell and then the particle would decay and hit the cancer cell with an alpha particle, killing the cancer cell. Since this isotope only decays once, so it won't kill any other cells, this could allow for a patient to be treated and cured of cancer, but not suffer any side-effects.     

With thorium being one of the most common elements, on par with lead, we can avoid an energy crisis, ensure world peace and save the climate all in one move.

Thorium reactors also do not need to be pressurized, since the reactor operates at such high temperatures that the fuel melts, so the reactors will be cheaper to build than most fossil fuel plants and other outdated nuclear reactors. Also, the salts in the reactor will expand if the reaction gets to fast, and that will slow down the reaction and cool the reactor, all without human intervention, it's a self-sustained reactor that doesn't even have to be manned (as mentioned above as the temperatures oscillate due to how salts behave)
