Devil’s Advocate Of Systems Thinking

Systems Thinking

This system focuses on how the think being studied interacts with the other constituents of the system. Insects damaging the crops seem to be the big issues to the crops agriculture. By spraying pesticide intended to solve the problem actually make it worse because the way its unintended side effects change the system end up exacerbating the problem. Pesticide might slow down the growth of insect type “A” but eventually lead to greater number of insect type “B” because insect type “A” is no longer controlling the numbers of insect “B” to the same extent. My solution is to spray pesticide intended for insect type “A” on the first crop season and then on the following season, we’ll spray pesticide intended for insect type “B”. In this case we will eliminate both types of insect. Then again, how would pesticide affect the water and soil and the environment.

I believe with the pesticide example, killing insect "A" in one season, and killing insect "B" in the next is a perpetual process of the traditional way of thinking. So what about insect "C"? You could kill them off next season, but this whole process seems so inefficient for me. I believe with regards to sustainability, it is about being efficient with what you execute (set aside the effects of the chemicals to the soil). It is always nice to find natural ways, say of getting rid of insects. For example, gardeners will grow basil beside their tomatoes as a natural insect repellent. What's great about this is that there is no insect maintenance other than the plants itself. Now, I understand that this may not be the answer for every situation. But I feel one should first look for natural ways to achieve goals, rather than finding harmful, expensive, and time consuming ways of doing things.
