People living on mars?

Introduction

This discussion is going to show that indeed man cannot survive on the planet earth. Comment by Stephen Davis: I do not understand what you mean here since we do live on Earth.

Planet Mars is far away from the sun compared to Earth, and this explains why the planet has very low temperatures.

Annual average temperature of -64 Fahrenheit.

The planet is so cold with deserts, no gravity and little oxygen. Comment by Stephen Davis: Mars has gravity

Planet Mars is also inhabitable by humans because there is the presence of a vacuum

Can cause the skin, and other organs to rupture causing a quick, painful death to an individual.

1. An intense ultraviolet radiation and irritable dust make Mars unbearable for any living things.

1. Chemical oxidants that may not provide a conducive environment for life.

Conclusion

In conclusion, it is not possible for a human being wearing normal clothes to survive on Mars. Extremely low temperatures, vacuum, low oxygen level and absence of gravity makes it impossible to live on Mars. Additionally, ultraviolet radiation and irritable dust are also hindrances.

Thesis and Outline

There have been numerous debates on whether the planet Mars can be a second home for a human. Scientists have come up with explanations as to why Mars cannot support life. This discussion is going to show that indeed man cannot survive on the planet earth. Comment by Stephen Davis: ?

First and foremost, planet Mars is far away from the sun compared to Earth, and this explains why the planet has very low temperatures. It has an annual average temperature of -64 Fahrenheit, and this makes it impossible for it to support life. In some cases, the temperatures could go as low as -199 Fahrenheit. Therefore, for any human to make it to the planet Mars, he or she must have a space suit. However, its temperatures can rise to 80 Fahrenheit near the equator. The planet is so cold with deserts, no gravity and little oxygen.

Another factor that makes the planet Mars inhabitable by humans is the presence of a vacuum. Unlike the earth which has an atmospheric pressure that keeps our body intact, Mars has a vacuum that can cause the skin, and other organs rupture causing a quick, painful death to an individual. More importantly, the intense ultraviolet radiation and irritable dust make Mars unbearable for any living things. There are also other chemical oxidants that may not provide a conducive environment for life.

In conclusion, it is not possible for a human being wearing normal clothes to survive on Mars. Extremely low temperatures, vacuum, low oxygen level and absence of gravity makes it impossible to live on Mars. Additionally, ultraviolet radiation and irritable dust are also hindrances.
