pollution

Pollution is anything that makes our environment dirty or unhealthy. It can come from different sources, such as factories, cars, and even our own homes. Pollution can harm plants, animals, and even people.

There are many different types of pollution, including:

• Air pollution: This is caused by the release of harmful gases and particles into the air. Air pollution can cause respiratory problems, such as asthma and bronchitis. It can also contribute to climate change.
• Water pollution: This is caused by the release of waste into rivers, lakes, and oceans. Water pollution can kill fish and other aquatic animals. It can also make the water unsafe to drink.
• Land pollution: This is caused by the disposal of trash and other waste on land. Land pollution can contaminate soil and groundwater. It can also make it difficult for plants to grow.

Pollution is a serious problem that can have a big impact on our environment and our health. We can all help to reduce pollution by making small changes in our everyday lives, such as recycling, using less energy, and driving less.
