Environmental hazards are remedial measures
An environmental hazard is a substance, a state, or an event that has the
potential to threaten the surrounding natural environment/or adversely affect
people’s health, including pollution and natural disasters such as storms and
earthquakes.
Environmental hazards may be defined as those extreme events either natural or
anthropogenic which exceed the tolerable magnitude within or beyond certain
time limits, make adjustment difficult, resulting in catastrophic losses of
property, income, and lives.
As we know the environment provides us lots of services that are beneficial to whole biotic communities but the environment behaves badly sometimes to biotic community especially human, the activities of the environment that are potential to harm man or property or both is called environmental hazards. Environmental hazards are elements of circumstances in the environment that have the potential to cause harm to people or property or both. Environmental hazards can be natural or man-made hazards. In one line we can say, environmental hazards are the possibilities of risk caused by the environment.

1. Natural hazards and disaster and
- Volcanic Eruptions
- Earthquake
- Landslide
- Cyclones
- Lightening and Hailstorms
- Forest fires
- Cloud burst
- Floods and drought
- Cold waves and heat waves
- Human-induced landslides, earthquakes, mining.
- Release of poisonous gases from chemical factors
- Nuclear waste and explosion
- Eutrophication
- Epidemics
