Chapter 10: the autotrophic way of life (continued) Biodeterioration the destruction of the environment by microbes because of an initial disturbance by humans the destruction of human artefacts by microbes (may or may not be linked to an initial disturbance by humans) Example: dest(cid:396)u(cid:272)tio(cid:374) of (cid:862)a(cid:271)o(cid:448)e a(cid:374)d (cid:271)elo(cid:449)-g(cid:396)ou(cid:374)d(cid:863) (cid:373)i(cid:374)e(cid:396)al a(cid:396)tifa(cid:272)ts (cid:373)ade (cid:271)(cid:455) hu(cid:373)a(cid:374)s, acid mine drainage.
