Creating a plant-based pollution map using outdoor plant boxes is an innovative and eco-friendly way to monitor air quality in urban areas. Here’s a step-by-step guide to help you get started:

1. Select the Right Plants: Choose plants known for their air-purifying qualities, such as spider plants, peace lilies, or English ivy. These species absorb pollutants like formaldehyde and benzene, making them ideal for pollution mapping.

2. Place Plant Boxes Strategically: Distribute outdoor plant boxes across different locations in your city or neighborhood. Focus on high-traffic areas, industrial zones, and residential spaces to gather diverse data.

3. Monitor Plant Health: Regularly check the plants for signs of pollution damage, such as discolored leaves or stunted growth. Healthy plants indicate cleaner air, while stressed plants may signal higher pollution levels.

4. Document and Analyze Data: Record your observations, including plant health, location, and environmental conditions. Use this data to create a visual pollution map, highlighting areas with higher or lower pollution levels.

5. Share Your Findings: Publish your pollution map online or share it with local communities and authorities to raise awareness and advocate for cleaner air initiatives.

By leveraging outdoor plant boxes, you can contribute to a greener, healthier environment while empowering others to take action against urban pollution.
