23 triệu vào rủi ro của bệnh từ nước bẩn
Hơn 300 triệu người ở châu Á, châu Phi và Mỹ Latinh có nguy cơ bị các bệnh đe dọa tính mạng như dịch tả và thương hàn do sự ô nhiễm ngày càng tăng của nước ở các sông, hồ, Chương trình Môi trường Liên Hiệp Quốc cho biết.
Giữa năm 1990 và 2010, ô nhiễm do virus, vi khuẩn và các vi sinh vật khác, và lâu dài các chất ô nhiễm độc hại như phân bón hoặc xăng, tăng hơn một nửa trong số các con sông trên ba châu lục, trong khi độ mặn tăng trong gần một phần ba, UNEP cho biết trong một báo cáo.
tăng trưởng dân số, mở rộng nông nghiệp và gia tăng lượng nước thải thô thải vào sông, hồ là một trong những lý do chính đằng sau sự gia tăng ô nhiễm nước mặt, đưa 323 triệu người có nguy cơ nhiễm trùng, UNEP cho biết.
"Vấn đề chất lượng nước ở quy mô toàn cầu và số lượng người bị ảnh hưởng bởi chất lượng nước xấu là nặng nề hơn nhiều so với chúng tôi dự kiến," Dietrich Borchardt, tác giả chính của báo cáo, nói với Thomson Reuters Foundation.
Tuy nhiên, một số lượng đáng kể của dòng sông vẫn còn trong tình trạng tốt và cần được bảo vệ, ông nói qua điện thoại từ Đức.
Khoảng một phần tư con sông ở châu Mỹ Latinh, 10 phần trăm đến 25 phần trăm ở Châu Phi và lên đến 50 phần trăm ở Châu Á đã bị ảnh hưởng bởi ô nhiễm mầm bệnh nặng, phần lớn là do xả nước thải chưa qua xử lý vào sông hồ, báo cáo cho biết.

People all over the world are worried about what is happening to the environment (4), because of modern industry and the need for more and more energy. Newspapers and magazines write (5) about water pollution, air pollution, and land pollution.
Why is there so much discussion about pollution (6)? After all, people have been polluting the world around (7) them for thousands and thousands of years. But in the past (8), there were not many (9) people and there was lots of room in the world so people could move to another place when (10) their settlements became dirty.
Now, however, many parts of the world are crowded (11). People live in big cities and much of our waste, especially waste (12) from factories, electric power stations, the chemical industry and heavy industry is (13) very dangerous. Fish die in the lakes, rivers, and seas; forest trees die too. Much of this dangerous (14) waste goes into the air and is carried by the wind (15) for great distances.
