Answer 2

HARMFUL EFFECTS OF BACTERIA: the only harmful effects of bacteria that you need to concern yourself with, is that they can cause disease and death.

USEFUL EFFECTS OF BACTERIA: (1) some bacteria such as E.coli actually produce beneficial by products for their host , such as vitamin K for humans.

(2) This ones a stretch for the layman, but bacteria are necessary for studying the life cycles of various viruses.

(3) Recently, a type of bacteria has been discovered that 'eats' plastic . with some refinement , that's going to have a major beneficial impact on the impact of plastics on the environment.

(4) another stretch of sorts , but bacteria actually helps to limit infections by other dangerous bacteria, both by competing for space and nutrients and by producing chemicals that kill or inhabit similar bacteria.
