What is the relationship between ecological environment and human health?

Man and the environment are inseparable, interacting, restricting, interdependent and adaptive. The deterioration of ecological environment, especially environmental pollution, has caused various hazards to human health, which can be divided into acute and chronic hazards and long-term hazards of carcinogenesis and teratogenesis. Humans should choose a development model that is harmonious with nature, which not only meets the needs of human development, but also protects the natural ecosystem to the maximum extent.
