pollination requires pollinating animals & pollination requires pollinating animals1 ->  plant reproduction requires pollination by pollinating animals  plant reproduction requires pollination by pollinating animals & a plant is a kind of living thing & if a living thing requires something then that something has a positive impact on that living thing ->  pollination by pollinating animals has a positive impact on plant reproduction  pollination by pollinating animals has a positive impact on plant reproduction & an insect is a pollinating animal ->  pollination by insects has a positive impact on plant reproduction  pollination by insects has a positive impact on plant reproduction & crops are a kind of edible plant for eating ->  pollination by insects has a positive impact on crop reproduction  pollination requires pollinating animals0 & pollination requires pollinating animals2 ->  an animal needs to eat for survival  an animal needs to eat for survival & humans eat crops & a human is a kind of animal ->  humans are animals that can eat crops for survival  humans are animals that can eat crops for survival & if an animal does something for survival then that something has a positive impact on that animal's survival ->  eating crops has a positive impact on a human's survival  pollination by insects has a positive impact on crop reproduction & eating crops has a positive impact on a human's survival ->  insects can have a positive impact on humans by pollinating crops  insects can have a positive impact on humans by pollinating crops & some crops are flowering plants -> insects can have a positive impact on humans by pollinating flowering plants
