The following are benefits of circular design thinking except ______*2 pointsActive learningWork on real caseEnable radical innovationIndustrial ecology

The question seems to be asking for the option that is not a benefit of circular design thinking. The options provided are:

1. Active learning
2. Work on real case
3. Enable radical innovation
4. Industrial ecology

To answer this question, we need to understand what circular design thinking is. Circular design thinking is a methodology that considers the entire life cycle of a product, from design to disposal, with the aim of minimizing waste and maximizing sustainability.

Now, let's analyze each option:

1. Active learning: This could be a benefit of circular design thinking as it involves a continuous process of learning and improving designs to make them more sustainable.

2. Work on real case: This could also be a benefit as circular design thinking is often applied to real-world cases to solve actual problems.

3. Enable radical innovation: This is definitely a benefit as the approach can lead to innovative solutions that significantly reduce waste and increase sustainability.

4. Industrial ecology: This seems to be the least related to the benefits of circular design thinking. While industrial ecology is a field that studies industrial systems with a focus on finding ways to make them more sustainable, it's not a direct benefit of circular design thinking.

So, the answer would be "Industrial ecology".
