672 - How do humans impact water quality in rivers and lakes?

Humans can impact water quality in rivers and lakes in several ways:

1. Pollution: When we throw trash, chemicals, and waste into rivers and lakes, it makes the water dirty and unhealthy for animals.
2. Fertilizers and pesticides: When we use fertilizers and pesticides in our gardens and farms, they can run into rivers and lakes, harming fish and other animals.
3. Sewage: When we don't treat sewage properly, it can flow into rivers and lakes, spreading diseases and making the water smell bad.
4. Industrial waste: Factories and industries can release chemicals and toxic substances into rivers and lakes, hurting the environment.
5. Litter: When we litter, it can end up in rivers and lakes, hurting animals and making the water look ugly.

We can help protect our rivers and lakes by:

• Not throwing trash into them
• Using natural fertilizers and pesticides
• Supporting clean water treatment
• Reducing industrial waste
• Picking up litter

Remember, every small action can make a big difference in keeping our rivers and lakes clean and healthy!
