Many scientists believe it would be possible to maintain a permanent human presence on Mars or the Moon. On the other hand, conditions on Venus are so extreme and inhospitable that maintaining a human presence there would be impossible.

First, atmospheric pressure at Venus' surface is at least 90 times greater than the pressure at Earth’s surface. This means that a force of 100 kilograms is pressing down on every square centimeter of surface. All spacecraft that have landed on Venus have been crushed by this extreme pressure within an hour of landing. Almost anything humans might land on Venus would be crushed as well.

Second, as far as we know, there are no reservoirs of water on Venus’ surface, and the planet’s atmosphere, made up mostly of carbon dioxide, nitrogen, and sulfuric acid, contains hardly any oxygen or water vapor. Water and oxygen would therefore probably have to be supplied to Venus from Earth. The idea of ensuring a regular supply of water and oxygen from Earth is impractical in the extreme and would probably defeat the purpose of establishing a permanent station on Venus.

Third, very little sunlight reaches the planet’s surface. About 60 percent of the sunlight that hits Venus is reflected back into space by the thick clouds that fill the atmosphere, which means that only 40 percent of the sunlight can get through the clouds. Below these clouds is a dense layer of carbon dioxide, which blocks even more light, so very little light reaches the surface. The lack of light would prevent the use of solar power cells, so humans could not get electricity to power their machines and equipment.

The article states about the presence of the human on venus is quite impossible. However, the lecture completely opposes the point made in the reading. The professor says that it certainly possible.
First, the article posits that venus have high atmospheric pressure than earth and due to this stations and human will crashed if they will land on venus. This point is contradicted by the professor. he says that this problem will be solved if the station float above the 50 kilometers above the ground like the balloon. He further explains this point by the physical fact, higher the atmosphere leads to decrease in the pressure. Eventually, no station will crash.
Second, the reading claims that human can not survive on venus because there is no water and oxygen and we could not supply enough water and oxygen from the earth to the venus. However, the lecturer states that venus have other gasses like carbon dioxide and sulfur dioxide and by the chemical process we can produce enough oxygen and water which will necessary for human survival.
Finally, the reading states that on venus we could not produce electricity because clouds are blocking sunlight and it could not reach the ground. The professor contradicts that point by saying that it is true, could reflect sunlight, however, the cloud thickness is not considerable. Furthermore, he explains that the solar power cells can collect sunlight from the above and below of clouds and by that way we can produce electricity.
