Indeed system thinking is useful but you seem to be missing that no prediction js ever accurate, nor can any system model fully cover the real complexity. System thinking is a tool, not the ultimate truth, and your system model will always be imperfect. Even if your model was perfect, you should not simply assume that a theoretical future really holds moral weight beyond that of the actual present. Feeding a duck today means two hungry ducks next year. Possible. Feeding a hungry human today means two hungry humans next year. Possible. But are you going to let a human (or a duck for that matter) starve to death to avoid theoretical future suffering, especially when the outcome is not guaranteed? What if the one you saved is a unique duck whose genes will make all offspring resistant to a certain pathogen? What if the human will be an important contributor to mankind's future? Or what if this human won't have children? Or what if they will be fed two days later by someone else regardless, which means your choice not to feed them only prolonged their suffering with no change in long-term outcome? Brought ad absurdum: the only moral choice is nuclear war - kill us all now to reduce future suffering of our children, grandchildren, etc. System thinking is useful, but don't think it has magical powers. Applied it helps you to see a broader horizon but it is always as flawed as your assumptions and model.
