Human Practices

Responsible: Our experiment, which is to reuse carbon dioxide, but there are still more convenient and cheaper ways to do it. For instance, the most common way is to put carbon dioxide in liquid to make a carbonated drink. Moreover, increasing the reuse of carbon dioxide through our experimental apparatus can only reduce the harm caused by carbon dioxide to the environment to a limited extent. The society also needs more ways to deal with and increases the reuse of carbon dioxide. Our team will compare our own experiments with existing inventions in terms of resource utilization, etc., so as to analyze which part of our experiments is different from other experiments in terms of energy utilization. Then we will make improvements in the experiment to minimize the waste of energy. The potential problem is the exploitation of wild bacteria, it may damage the ecosystem. We will contact the department of ecological environment and tell them, "We will try our best to carry out the exploitation on the premise that the ecological environment will not be damaged." In society, the current policy applies to our experiment. Because nowadays, the government also advocates decreasing the carbon dioxide portion in the atmosphere. We also can ensure safety during the experiment. The electrochemical devices used in our team's experiments only need to be electrified, no additional operation is required, and no dangerous substances such as fire is needed. In addition, the plasmids used in our experiments, Escherichia coli, Roche, and wild bacteria, are harmless and do not cause any harmful effects on animals or humans. Although this experiment has established a relatively reasonable and scientific theoretical framework system and attained some modest success in practical operation, it is still restricted by multiple factors, which inevitably leads to certain limitations. Therefore, there are many aspects that can be improved and optimized.

Good: Lycopene, the product of our experiment, can be used as the raw material of many cosmetics, food, and even health products, which can meet part of people's needs. At the same time, the experiment can also increase the reuse of carbon dioxide, and make a small contribution to reducing the greenhouse effect caused by carbon dioxide. Some organizations that study air pollution and the greenhouse effect may be attracted by the benefits of our experiments because reducing the greenhouse effect and increasing the reuse of carbon dioxide have always been an urgent problem to be solved in modern society. Meanwhile, some organizations with similar ideas also influence groups that also want to play their part in increasing the reuse of carbon dioxide through their own experiments and interfere with their influence in society. As a result, we obtained the lycopene yield from the final experiment and compared it with the lycopene yield of Escherichia coli without the lycopene gene in the presence of Ralstonia. Then, by changing different variables in the experiment, such as electrode materials, and analyzing the change of lycopene yield, an effective transformation method was finally found. However, our experiment can be used as a way to reuse carbon dioxide, but at the same time, compared with the production of other carbonated drinks, our method is not efficient or simple, because we need to find wild bacteria suitable for the experiment in nature and transfer them to others, which is not only time-consuming and wasteful of resources.
