It can be caused by natural disasters like hurricanes, earthquakes, floods, or by human activities such as pollution, deforestation, or industrial accidents. These hazards can pose serious threats to the lives and properties of people and can cause significant damage to the environment. Therefore, it is important to identify and manage environmental hazards to minimize their impact and protect the well-being of people and the environment.
