Why is hydrogen important to life on earth?

Answer 1

Hydrogen makes up 75% of the universe's known matter.

Stars are almost entirely made of hydrogen gas that is compressed in the centre of the star to such gigantic pressure that the temperature rises to such an extent that hydrogen atoms fuse together forming helium atoms. This process of 'atomic fusion' releases enormous amounts of energy - sufficient to keep stars emitting energy in the form of heat, light and radiation for millions of years. Our sun, being a typical star, is fuelled by this atomic fusion thanks to it being made almost entirely of hydrogen, providing us with all our energy needs, and providing energy for plants to grow and produce their own food through photosynthesis, and therefore, as we eat plants (or animals that eat plants) it provides every material thing we need to survive. Therefore, without hydrogen our sun would not exist, and so neither would we.

Answer 2

Hydrogen is ultimately what everything else was made from through the process of stellar nucleosynthesis.

Aside from that, it's also vitally important because hydrogen bonding is what holds many proteins in the particular shapes they need to be in order to work, and what holds the twin strands of DNA together.

Answer 3

We must be finding, soon, a means of producing vast quantities of hydrogen to replace all coal, oil, or natural gas for the propulsion of all transport vehicles -- because hydrogen is the only fuel that can be used in any engine that uses the combustion process to develop the thermal energy to power the vehicle. The

engineers in Isarael have designed the "Energy Towers" -- the Desert Down-draft

Chimneys -- but no one has as yet considered their design economically feasible.

I have a design -- for an Hydrogen [or Helium} supported Energy Tower, which

can well be economical -- and accomplish the task!

It should be carefully considered by scientists and engineers -- to enable Humanity

to completely replace the combustion process, in order to begin the change -- to

reverse both the GLOBAL WARMING, AND, GLOBAL WARFARE as well !! Only TWO

FORCES, GRAVITY, AND THE PHASE CHANGE OF WATER --CAN DO THE JOB -!!

Those forces have existed -- just as well as CHLOROPHYLL, for mankind to use !!

Answer 4

Hydrogen is important to life on Earth because it is a key component of water (H2O), which is essential for all living organisms. Additionally, hydrogen is a component of many organic molecules such as carbohydrates, fats, and proteins, which are vital for the functioning of cells and organisms.
