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! :)
