The smallest organisms participate in systems larger creatures depend on.

The organisms too small to notice are the ones running the systems everything else depends on: the soil, the gut, the nutrient cycle, the pollination. Size and visibility have almost no relationship to importance, and the biggest creature in the landscape is entirely at the mercy of the smallest.

Carry that into how you regard the people whose work supports yours. And into how you regard your own small contributions. Consequence rarely announces itself at the scale it operates.
