The author in the reading mainly discusses three benefits of asteroid colonization. However, the professor in the listening rebuts them because they are not practical.
First, the reading claims that low gravity of an asteroid would make the landing and taking off relatively easy, which is refuted in the listening because low-gravity environments also present certain risks. In a low-gravity environment, people start losing muscle mass and their bone density becomes lower. Even astronauts accustomed to low-gravity environments suffer from health problems.
Second, according to the reading material, mining on asteroids would be profitable, but the lecturer tells us that it is not the whole picture. Additional factors should be considered. For example, the costs of supporting a colony and of transporting metals are likely to be high and will reduce the profits. And there is no guarantee that the price of the metals will remain the same. If metals are mined in large quantities, it would increase the supply of them, which could end up lower in the market price.
Lastly, based on the third theory in reading, some asteroids are easy to reach, but the listening argues that they may not be easy to return from because asteroid orbits can be unusual. Some orbital paths come close to earth, but then move away from earth, often a great distance away from earth.
