The chaos theory is derived from mathematics to study non-linear and unpredictable systems. These systems are virtually uncontrollable, like turbulence or a human’s brain state. Part of why chaotic systems are unpredictable is due to the butterfly effect, 

The butterfly effect states that a small change in initial conditions results in drastic outcomes. 

Therefore, it can be argued that any ecosystem has the potential to be chaotic. An ecosystem relates every living being to each other (think of the food chain), and a change in this system is bound to cause ripple effects. However, there are simply too many variables which can result in unpredictable outcomes. 

Relating this to the situation in Southeast Asia, forest fires are becoming increasingly common at an accelerated rate. This can be due to the interaction between global warming and man-made forest fires. Forest fire releases carbon into the atmosphere, worsening global warming, which starts a cycle. However, this is an overly simplified system and thus, the chaos theory may not seem applicable. But we know that there are other factors involved; if other man-made factors, such as logging and forest conversion are taken into consideration, the model becomes complicated and the system becomes unpredictable.
