Bottled water is the standard of current conferences, which is generally provided by hotels free of charge, and a small amount is provided by conference organizers. Anyway, the phenomenon of "half a bottle of water" is common, and people often throw it away after drinking it. As long as it is opened, hotels generally treat it as garbage. A bottle of water seems worthless, just a few dollars, but the waste of water resources caused by not drinking all the drinking water for the meeting deserves public vigilance. According to the investigation of experts, it is conservatively estimated that there will always be more than 10% of bottled water left, and it is estimated that there are more than10 million bottles in China every year.

China is short of water resources, and the per capita water resources is less than a quarter of the world average. With the continuous development of society, China's industrial water consumption and urban water consumption are increasing, and the contradiction between supply and demand of water resources is becoming increasingly prominent, which has become an obstacle to industrial development and even social development. Moreover, bottled water needs to consume a lot of social resources in the process of production, transportation and sales. The phenomenon of "half bottle of water" will not only cause waste of water resources, but also bring about derivative problems such as waste of plastic packaging, waste of energy and pressure of environmental pollution.

It can be seen that advocating saving bottled water and stopping the waste of "half bottle of water" is not only practicing anti-food waste, but also saving precious resources, reducing energy consumption and alleviating environmental pollution, which is a major event that benefits the interests of the whole people. Previously, the "CD Action" initiated and adhered to by various localities has established a sense of saving food and putting an end to waste in the public mind. The concept of ordering food in moderation and packaging after eating has gradually taken root in people's hearts, and the phenomenon of food and beverage waste has been effectively curbed. Therefore, in view of the waste of bottled water, all localities can carry out "bottle cleaning action" to guide the public to establish the consciousness of saving water, so as to better protect and utilize water resources.
