It was created to help solve the lack of nutrition problem that was created by the staggering population growth of the human race. Nitrogen fertilizer represents the single largest investment of energy in the production of many crops, and circulation of reactive nitrogen can have negative effects on atmospheric conditions, in terrestrial ecosystems, in freshwater and marine systems, and on human health (journals.plos.org) This will probably still be the case in the near future for fish farming operations, as making the “right” decision is a complex task that is difficult to assign to computer-based systems without running a risk of unforeseen and potentially undesirable side effects (e.g. (NM1281, Revised Oct. 2017) When nutrients and other pollutants associated with animal manures and commercial fertilizers are not managed properly, they can affect plant and animal life (including humans) negatively. Glyphosate or glyphosate-containing products can cause sublethal effects such as erratic swimming and labored breathing, which increase the fish's chance of being eaten (Liong et al., 1988). A related issue is the poisoning of aquatic life. Global warming and greenhouse effects are the result, which is a massive impact of industrialization on the environment. The researchers suggest that the impact of fish-farming on vegetated and non-vegetated ecosystems should be assessed differently. In extensive systems the animals get food from their environment and are not fed by humans; humans control only the environment where the animals are kept.
