How did water get on earth?
As a standard comet nears the heat of the Sun, the ice particles from its nucleus sublimate or go directly from solid ice to a gas, which can then condense later into liquid water if it were, say, to arrive on a planet’s surface.
Can we make oxygen?
Oxygen can be produced from a number of materials, using several different methods. The most common natural method is photo-synthesis, in which plants use sunlight convert carbon dioxide in the air into oxygen. … This method is called electrolysis and produces very pure hydrogen and oxygen.
What year will we run out of oxygen?
52,535 yearsUsing estimates of the biomass of all animals and the oxygen content of the atmosphere, oxygen would be exhausted after 52,535 years, assuming a constant animal population.
Will we ever run out of water?
While our planet as a whole may never run out of water, it’s important to remember that clean freshwater is not always available where and when humans need it. In fact, half of the world’s freshwater can be found in only six countries. … Also, every drop of water that we use continues through the water cycle.

Will the earth run out of oil?
Globally, we currently consume the equivalent of over 11 billion tonnes of oil from fossil fuels every year. Crude oil reserves are vanishing at a rate of more than 4 billion tonnes a year – so if we carry on as we are, our known oil deposits could run out in just over 53 years.
What will happen to water in 2025?

How little oxygen Can a human survive on?
Human beings must breathe oxygen . . . to survive, and begin to suffer adverse health effects when the oxygen level of their breathing air drops below [19.5 percent oxygen]. Below 19.5 percent oxygen . . . , air is considered oxygen-deficient.
Can we create water?
Yes, one can take Hydrogen and Oxygen and react them in appropriate conditions and form water vapor. This can then be condensed (by cooling) to liquid water. This is the best way to produce the most purified water that has no other ions that are normally present in water we know.
Will the Earth die?
However, the long-term trend is for plant life to die off altogether. … By that point, all life on the Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
What will happen in 2050?
Stabilization in the population will happen in the second half of the century. It is calculated there will be 601,000 centenarians (people at least a hundred years old – born before 1950) in the United States by 2050. … According to this study, 9.075 billion people will inhabit Earth in 2050, against 7 billion today.
Can scientists make water?

How much water will there be in 2050?
If monthly, rather than annual, variability is considered, 3.6 billion people worldwide, slightly less than 50% of the global population, presently live in potential water-scarce areas at least 1 month per year. This number will increase from 33 to 58% to 4.8 to 5.7 billion by 2050.
What will happen when the earth runs out of water?
For Earth as a planet, running out of water has some serious consequences. … Environmental scientists predict that as well as sinking terrain over extraction of groundwater could also lead to an increased risk of earthquakes due to the fact that the Earth’s crust is becoming lighter.
Which states will run out of water first?
