Keep in mind that permaculture, as useful a tool as it is, is still vulnerable to the same dogmatic rhetoric as any other subject or skills. Permaculture designs improve the land and help humans work with nature, but only if the designs are carefully and critically evaluated.

For example, a often recommended technique well-known in most permaculture groups is sheet mulching, or using cardboard and/or newspaper to kill weeds, improve the soil and encourage beneficial soil organisms through the process of smothering. But is it actually helping, or do we just think it is? The science seems to suggest the practice is actually harmful to some extent.

So while permaculture may be one of the most optimal ways for humans to exist within nature, let us not forget that even permaculture techniques can be flawed, and we should always remember to think critically before believing any designs or recommendations--permaculture included--as incontrovertibly true.

Check out the Permaculture Science subreddit for more evidence-based permaculture techniques.
