People now do not realize that water supplies are in shortage. According to the videos, we are currently experiencing a water shortage and not everyone can save water sources instead of wasting water resources through daily and industrious usage. For developing countries, water prices are so low that everyone can afford it and they do not matter how much water is wasted. In addition to this, for developed countries, water is usually free to everyone which may lead to a more serious idea that people can waste water without any punishments. I think to better protect our water resources, the government needs to launch the relevant law and set up mandatory lectures for the public, which is about saving our water resources. Meanwhile, based on the videos, water cost is invisible to the public. For example, producing a t-shirt and a hamburger usually requires a large amount of water and such products are usually at a low price. I think that another way to protect our water resources is to make such invisible water costs visible to the public that they need to pay for water usage. Also, the root causes of such invisible water costs are companies that make such products. Companies now need to produce products of higher quality using fewer resources rather than wasting a huge amount of water to produce products of relatively low quality.
