"Hello,I really enjoyed the topic of this article. It seems like situations like this happen all the time in an attempt to change the environmentally hazardous materials we use in products today. We start somewhere natural, because we didn't have the technology, then technology comes along with its shiny new product that seems to be better but ends up costing us much more. And then we end up back where we started, trying to design something natural; and we often recreate something that once existed. But maybe this is the solution to other problems. How did we used to do things naturally? And is there a way to modernize that natural process? As a designer, I'm constantly asking myself these questions.

"Hello,Wonderful post about sustainable design. I think often designers see or hear about a potentially better material for production but often can fail to see the potential hazards that have not yet arisen from widespread use. Bio-plastic is a particularly interesting new material that has the potential to replace the over-used and harmful petroleum based products, but it has to made in a way that actually neutralizes or even reverses the effects of current harmful plastics. If you'd like to read about other potentially misleading ideas in sustainable design or new solutions to complicated problems, please visit my blog here http://amackaydesign.weebly.com/blog to read more about this topic.Thank you"

"Hello, I absolutely loved your post. I was quite familiar with eutrophication as a result of fertilizer buildup, but it's very important to recognize other sources of this damaging effect. As an environmental designer I'm constantly searching for ideas that solve multiple problems and address multiple concerns. I love how this toilet design is removing the problem of excess urine waste and using it as fertilizer. If you'd like, you can view my blog here: http://amackaydesign.weebly.com/blog. It's relatively new, but it covers topics related to environmentally friendly design, much like the urine-trapping toilet.Thank you."
