The reading passage contends that people cannot live on Venus because of the harsh environment.
On the other hand, the lecturer brings up several points that contradict this argument.
First, the speaker argues that installing a spacr station above the surface of Venus allows people to live in the harsh environment because there is the simmilar air pressure to that of earth in above the certain amount of height from the surface. This casts doubt on the reading which states that it is impossible to live on Venus because of such high level of air pressure.
Second, according to the lecturer, people can gain necessary substances for their survival though a chemical reaction. Although there are no independent subtances for life such as water and oxygen, it is possibe to obtain these kinds of substances by isolating them from compounds, already existing on Venus. Thus, they do not need an equipment to convey the required substances. This refutes the reading passge's assertion that shortage of necessary materials has a negative impact on people's survival.
The final point made by the lecturer is that people don't have to worry about sun rays because the layers of gas are not really thick enough to reflect all sun's rays. Furthermore in the case of structure above of the amount of height from the surface, the layer's definitely cannot be a problem of energy because the sun rays can heat the surface enough. In addition, the planet rotates so slowly that people can get enough heat energy through soloral panel. This counters the writer's claim that people cannot live on Venus because of the thick layers of gas. |
