Sử dụng nguồn nước hợp lý, đảm bảo vệ sinh
nh minh họa- Nước là nguồn tài nguyên thiên nhiên vô cùng quý giá đối với con người; nước dùng để sinh hoạt hàng ngày như tắm rửa, ăn uống, bảo quản các loại thực phẩm, dùng phục vụ cho việc sản xuất. Đặc biệt ngay trong cơ thể, mỗi chúng ta nước cũng chứa 70-75% trọng lượng cơ thể, nếu thiếu nước cơ thể chúng ta sẽ bị rối loạn các quá trình chuyển hóa chất. Mặc dù nước quan trong như vậy nhưng không phải nguồn nước nào chúng ta cũng sử dụng được mà chỉ sử dụng nguồn nước sạch.
