ANIMALS, PEOPLE AND THOSE IN BETWEEN
Many good posts on systems, boundary critique, climate.
…where systems thinking really gets interesting is when we include ourselves as part of the system we’re describing. For example, for the climate system, we should include ourselves as elements of the system, as the many of our actions affect the release of greenhouse gases. But we’re also the agents that give some aspects of the system their meaning or purpose – the fossil fuel extraction and production system exists to provide us with energy, and one could even argue that the climate system exists to provide us with suitable conditions to live in, and that ecosystems exist to provide us with food, resources, and even a sense of wonder and belonging. The interesting part of this is that different people will ascribe different meanings and/or purposes to these systems, and some would argue that to ascribe such purposes is inappropriate.
