What is the most advanced approach to dealing with waste? 

A)  recycling materials 
B)  using biodegradable material 
C)  reducing the amount of materials used 
D)  creating more durable products

The most advanced approach to dealing with waste is reducing the amount of materials used. This is because it tackles the root cause of the problem instead of just treating the symptoms. By reducing the amount of materials used, we decrease the amount of waste generated in the first place, leading to a more sustainable and efficient system. Recycling and using biodegradable materials are also important strategies, but they are not as effective as reducing the amount of materials used. Creating more durable products is also a good approach, but it must be combined with reducing the amount of materials used to maximize its impact.
