3.The 2022 Winter Olympics were held in Beijing,China,and in two areas northwest of Beijing,Yanqing and Zhangiiakou.The areas get cold in winter,but they don't get a lot of snow because they're not far from the Gobi Desert,and are generally very dry.That meant some serious changes were needed to hold the Winter Olympics there.China took water from a reservoir which helps supply Beijing's drinking water and sent it to a nearby river.To carry the water to the mountains for making snow,the country ran miles and miles of pipes.China says making the snow took about 185,500 liters of water.This is the first time the Winter Olympics has taken place on almost 100% artificial snow.
The snow at this year's Winter Olympics was made with wind and solar energy.And the machines that make artificial snow are quite advanced.They can make several different kinds of snow depending on what's needed for each sport.For example,the snow they make for downhill skiing is different from the snow made for cross-country skiing.
It's useful to be able to make snow when nature doesn't provide enough.But artificial snow isn't the same as natural snow,which has more air and less water.An athlete used to natural snow might have to adjust their style on man-made snow.A few athletes have complained about the snow at this year's Olympics.Most others say it's been just fine.
In recent years,it has become more and more common to use artificial snow at winter sports events.That's true even in places that used to have a lot of snow naturally.Some artificial snow was used in the Winter Olympics in 2010 and 2014 because of warm weather.In the 2018 Games in Pyeongchang,South Korea,roughly 90% of the snow was man-made.
As the world warms because of climate change,problems like this are expected to become far more common.You could not have winter sports now without man-made snow.
