I prefer Public health and want to build my carrier in Public health in the upcoming days.

Environment as a discipline of Public health:

Environmental health is the branch of public health that: focuses on the relationships between people and their environment; promotes human health and well-being; and fosters healthy and safe communities. Environmental health is a key part of any comprehensive public health system.

As a core discipline of public health, environmental health is concerned with the delineation of environmental factors and their relationship to human health. These factors include air, food, water, radiation, toxic chemicals, wastes, disease vectors, safety hazards, and habitat.

A number of specific environmental issues can impede human health and wellness. These issues include chemical pollution, air pollution, climate change, disease-causing microbes, lack of access to health care, poor infrastructure, and poor water quality.
