Glaciers are bomb, just wanting to start with something exciting. Did you know 69% of the world's fresh water supplies is held in glaciers and polar ice-caps. Another 21% of the world's fresh water are held in the Great Lakes
Basin. The final 20% of the worlds water is locked up in Lake Baikal Basin. If you don't know all glacier water that is trapped in glaciers are fresh. This leaves only about 16% of fresh water is available for us, and that is why the
government gives us water restrictions. You wouldn't want the ice caps to melt because the sea level would rise about 230 ft.
The worlds fresh water supply is only 2.5% of the world, compared to salt water too.
All the worlds water is captured in this graph.
Fresh water is needed in many countries. It may be the country's only source of water, But what we are doing to our planet is ruining it. Some people need it for bathing, they dont have water pipes. Imagine having no fresh drinking water or water for bathing.
Glaciers are formed by snow and compacted into ice. To form a glacier it must snow and if there are any left when the next summer passes over and it snows again and continues for a few more years just like that. The snow that is underneath all those layers will be compacted under the pressure of all the snow and turn into ice.

If you have never seen a glacier here is one now, this is the Wolverine Glacier in Alaska. There are more of these glaciers than just 100, there are more than 10,000 glaciers in the world, but not all huge like this one. 10% of Earth is covered by glaciers and not all fresh water are the same amount in all of them, it depends on how big it is and how much snow it took to create it. There are around 5,000 glaciers in Alaska. It is assumed that the glacier is .90 kg/L. Because of Global Warming many ice glaciers are melting including the North or South Pole and temperature of the Earth is increasing, this is one of those glaciers that are melting. We use too much fossil fuel, and if we stop, nothing will change, we still need other countries to stop producing things and that will might change and lower the CO2 levels.
You can do something about this, you can spread the word. Do something to cut back on Co2, use less energy.
An old man freezing because he has no water in his house, good he has the glacier.
