The summary of the text is: Water pollution is a significant problem worldwide, with heavy metals and other toxic substances being discharged into water sources, causing harm to both human health and the environment. Many countries lack adequate laws and infrastructure to clean polluted water, resulting in 2/3 of the global population not having access to clean water. The consequences of water pollution extend beyond human health, with many species and plants facing extinction due to habitat loss and impaired nutrition. To address this problem, international cooperation is necessary, including the construction of more sewage treatment plants, reduction of artificial fertilizers, stricter laws and regulations, and support for new technologies for waste recycling. Additionally, consumers must become aware of the importance of waste prevention in mitigating water pollution.
