Pollution
Pollution is the introduction of harmful substances or products into the environment. This can cause long-term damage to the ecosystem and human health. There are several types of pollution, including air pollution, water pollution, and soil pollution.
Causes of Pollution
There are many causes of pollution, including:
- Industrial activities
- Vehicle emissions
- Agricultural practices
- Improper waste disposal
- Deforestation
- Use of chemicals and pesticides
Effects of Pollution
The effects of pollution can be devastating. They include:
- Damage to ecosystems and loss of biodiversity
- Health problems in humans, such as respiratory issues and diseases
- Contamination of water sources, making them unsafe for consumption
- Soil degradation, affecting agricultural productivity
- Climate change and global warming
Preventing Pollution
Preventing pollution is essential for the health of the planet and all living organisms. Some ways to prevent pollution include:
- Using alternative energy sources
- Reducing, reusing, and recycling materials
- Implementing stricter regulations on industrial emissions
- Properly disposing of hazardous waste
- Conserving water and using it efficiently
- Planting trees and promoting green spaces

Earth/Space Science: Students will use scientific skills and processes to explain the chemical and physical interactions (i.e., natural forces and cycles, transfer of energy) of the environment, Earth, and the universe that occur over time.
Earth History: Explain how sedimentary rock is formed periodically, embedding plant and animal remains and leaving a record of the sequence in which the plants and animals appeared and disappeared.
Explain how sedimentary rock buried deep enough may be reformed by pressure and heat and these reformed rock layers may be forced up again to become land surface and even mountains.
Explain why some fossils found in the top layers of sedimentary rock are older then those found beneath in lower layers: Folding; Breaking; Uplift; Faulting; Tilting.
