- Brazil – 400 million tonnes.
- China – 340 million tonnes.
- India – 230 million tonnes.

Will we run out of iron?
Currently worked iron deposits are estimated to be depleted in as little as 65 years (Most estimates place that number much much longer). Although, like oil, other deposits will become economically developable as easier deposits are depleted. Eventually, yes, we’ll even be able to mine iron asteroids economically.
Will the earth 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.
How long till the earth is overpopulated?

What happens if we run out of water?
Due to their large surface area, they lose a lot of water to evaporation. If this happened, it wouldn’t take long for the common water supply to become unsanitary under these conditions. The polluted water supply would kill aquatic life, further reducing the available food supply.
What year will we run out of freshwater?
Increased Energy Requirements by a Growing Population The International Energy Agency projects that at current rates, freshwater used for water production will double over the next 25 years. At the current pace, there will not be enough freshwater available to meet global energy needs by 2040.
Can scientists make water?
The answer: very. Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. If we can’t make water easily from its atoms, are there any other ways we can create it? Well, scientists are now focusing more on harvesting water from the air and using humidity to their advantage.
Where is the freshest water on Earth?
Over 68 percent of the fresh water on Earth is found in icecaps and glaciers, and just over 30 percent is found in ground water. Only about 0.3 percent of our fresh water is found in the surface water of lakes, rivers, and swamps.
What is the main source of fresh water?
Sources. The original source of almost all fresh water is precipitation from the atmosphere, in the form of mist, rain and snow. Fresh water falling as mist, rain or snow contains materials dissolved from the atmosphere and material from the sea and land over which the rain bearing clouds have traveled.
What are the 3 types of water?
Water can occur in three states: solid (ice), liquid or gas (vapor).
What animals live in freshwater?
More Than Fish Fish living in freshwater habitats have plenty of company. Snails, worms, turtles, frogs, marsh birds, mollusks, alligators, beavers, otters, snakes, and many types of insects live there too. Some unusual animals, like the river dolphin and the diving bell spider, are freshwater creatures.
What does salt water mean?
Saline water (also called salt water, salt-water or saltwater) is water with a high amount of salt in it. It often means the water from the seas (sea water) and oceans. Almost all the water on Earth is saline.
