Milli鈥檚 Grandpa was talking with his old friend, Mr. Gupta, who was visiting from India. 鈥淗ow is your area handling the drought?鈥�, her grandfather asked. Mr.聽Gupta answered: 鈥淕lacier melt is helping us fight the drought. Our lakes are have more water again, so we can still water our crops. But what happens if we don鈥檛 get enough snow in the mountains? The glacier is getting smaller and smaller each year.鈥�
鈥淎 glacier in India?鈥� Milli thought. 鈥淗ow can there be a glacier in India? It鈥檚 much too hot there.鈥�
After Mr. Gupta left, Milli asked her grandfather about the glacier in India. He got a map and showed Milli where Mr. Gupta lived in northern India, close to the Himalayan mountains. He said, 鈥淲hen the glacier melts, the water runs off and feeds rivers and streams. These waterways bring water to the farming areas in the south. Millions of people in the region need that water. Glaciers need to have sufficient snow each year to bring water to people living there.鈥澛�
Her grandfather went on: 鈥淎bout 2% of all the water on earth is frozen in glaciers. That doesn鈥檛 sound like much, but most of the water on earth is salt water, in the oceans. People can鈥檛 use salt water for drinking or cooking. Most of earth鈥檚 freshwater (68%) is stored in the glaciers. Glaciers are our largest supply of fresh water! Glacial meltwater is used for irrigation, hydropower,聽and by people living downstream. They are a good water resource for one-third of the world鈥檚 population.鈥�
Milli鈥檚 Grandpa also said, 鈥淥ther than Greenland and Antarctica, 26% of the land on the other continents is supplied with water from glaciers and snow. Almost 1 out of every 5 people (1.4 billion) depend on that water. The glaciers act like huge water towers, storing water during the cold seasons and releasing it during dry summers.鈥�
鈥淭hat鈥檚 super cool, Grandpa!鈥� Milli exclaimed. 鈥淧eople will never have to worry about having enough water!鈥� But he replied, 鈥淯nfortunately, glaciers are shrinking all over the world, and lose around 225 gigatons of water every year, which is 225 billion tons! As they shrink, they provide less and less water. Around 45% of glaciers have passed their peak and are declining.鈥� 鈥淭he loss is worst in the U.S. and northern Canada, but it鈥檚 also bad in the Himalayas and in South America.鈥�
鈥淥h my,鈥� said Milli, 鈥淚 had no idea!鈥� Her grandfather said, 鈥淲ater is so important, but most people don鈥檛 even know where their water comes from. That鈥檚 why we have to protect our sources of water and take action so we always have fresh water to use.鈥�
鈥淚 am certainly going to learn more about this!鈥� said Milli. 鈥淭ime for me to figure out what I can do to help.鈥澛� 聽
