Which Is The Best Topic For An Environmental Project?

When you pick an environment project, focus on city food waste. It has clear benefits:

Urban Food Waste Reduction

City food waste is a big problem. One in three bites of food made in the world is thrown away. This vents bad air, wastes water, and wastes materials.

This project could include:

• Compost bin
  
• Restaurant-food link
  
• Meal planning tips
  
• Waste tracker app
  

Why This Topic Is Optimal

This topic works well because:

• Quick, clear results
  
• Helps earth and saves money
  
• Brings people together
  
• Fits small or large areas
  
• Mixes tech and good habits
  

Alternative Topics to Consider

If food waste is not for you, try:

• Saving city water
  
• Helping local wildlife
  
• Better city transport
  
• Clean community energy
