Answer:
human manufactured risk, the effects may be mitigated
Explanation:
According to my research on the studies of Ulrich Beck, I can say that based on the information provided within the question this can be understood as a "risk society" because as a human manufactured risk, the effects may be mitigated. This is said because in this situation the risks are of carbon emissions to our environment caused by humans burning the gas collected, since it is a risk that is caused by our actions, then it can be said that we can take actions to lower this risk or even completely eliminate it.
