By this process astronaut can grow plant or vegetables in aerospace, again these vegetables release O2 and absorb CO2 so they breath with fresh air also.
Second, the author claims that long journey to space or zero gravity environment can cause severe harm to human body but the lecturer opposes these. She says that astronaut have experience of staying several month in such environment and if they do regular exercise or take calcium the problem might be solved since it help to reduce the lowering the bone density.
Third, the author also mentions that dangerous solar radiation in the interplanetary space would harmful for astronaut but the lecturer also clarify that, she says solar radiation is not harmful all the time, it can cause damage for some times. If the astronaut can use special technology to detect the harmful radiation they can save them from the harmful radiation.
