Environmental hazard means something that can cause harm to the environment, the living creatures and things living in it, and the natural processes that make the earth a safe place to live. Some of the common environmental hazards are pollution, climate change, deforestation, and wildlife extinction.
Pollution is when harmful substances like chemicals, waste or garbage get into the air, water or soil, and can make people, animals, and plants sick. For example, if we throw garbage in the river, it can pollute the water and harm fishes living in it.
Climate change is when the temperature of the earth increases due to human activities like burning fossil fuels, which releases gases that trap heat in the atmosphere. This can cause many problems like drought, floods, and extreme weather conditions.
Deforestation is when we cut down trees and clear forests to make space for buildings or agriculture. This can harm wildlife which depends on the forest for food and shelter, and also disturb the natural cycles that help maintain the balance of the ecosystem.
Wildlife extinction is when a particular species of plant or animal dies out completely. This usually happens when their habitat is destroyed or when they are hunted or overexploited.
In summary, environmental hazards are things we need to be careful of because they can cause harm to nature and living creatures. We should always try to reduce our impact on the environment by using resources wisely, recycling, and protecting wildlife and their habitats.
