An environmental hazard refers to any substance, state, or event that can cause harm to the environment or human health. This includes pollutants like chemicals, heavy metals, and waste products that can contaminate air, water, and soil. Natural events such as earthquakes or floods can also pose risks by damaging ecosystems and human settlements. These hazards can lead to serious consequences, including health issues, loss of biodiversity, and economic impacts. Understanding and managing environmental hazards is crucial for protecting both the planet and public health. Efforts include monitoring, regulation, and community awareness to mitigate risks.
