Predict some of the consequences of elinminating all bacteria from an environment?

Without bacteria life as we know it would not be possible.

Explanation:

Bacteria play a major role in processing organic waste in every environment. If all bacteria are eliminated from an environment, waste would pile up. Plants depend on nitrogen fixing bacteria to convert unusable gaseous nitrogen into usable nitrogenous compounds such as ammonia, without which they could not survive. Most vertebrate, and many invertebrates depend on bacteria living in their guts to help digest food. Ruminants, for example, depend on bacteria in the rumen of the stomach to break down cellulose, allowing them to survive on grasses with very little nutritional value.
