Which has been a negative impact of technology?

a. more human labor
b. less farming
c. less access to food
d. more waste

More waste has been a negative impact of technology, as more human labor is not a bad thing as it employs people and earns them money to support themselves and their families. Less farming and less access to food are not a direct effect of technology; in fact, technology improves farming and allows more crop yield. Hope this helps! :)

Ibelieve the answer is relative humidity  because it makes more sense that way. solar flares usually occur in space it doesn't affect the earth, well it could but it wont make a significant damage.  latitude is land it doesnt do anything. prevailing winds, i dont know the correct meaning for this but i doubt that affects the land so it has to be relative humidity.
