Should NASA Send Humans to Mars?

If you had the chance to go to Mars, would you? Before you say yes, think again. NASA shouldn't send humans to Mars because our germs will contaminate Mars and vice versa, life there will be harsh and dangerous, and the mission is costly. 

Firstly, like I've stated before, germs from Earth will contaminate Mars and life on Mars may wipe out for good. NASA believes that Mars has tiny forms of bacteria. And once humans land on Mars, Martian germs may harm us as well. 

Another reason why is because the human body cannot simply function well on Mars. Muscles and bones get weaker and the body produces less blood. This causes hypoglycemia, which happens when the blood sugar levels are low. NASA will also have to provide food, water, and oxygen because just to travel to Mars, it'll take 10 months, not including the time period for the colonization. 

Lastly, again, the mission will take a very long time and will require patience, and it will cost $1 trillion, which is very expensive. 

On the other hand, the technology that NASA creates may improve life on Earth, and we, as humans, will get more information about our neighbor planet. Also, the population is increasing, and people may need more space. But do we have to go to Mars to get a better life here, risking astronauts' lives? Sure, we will receive more information about Mars, but can't NASA send robots and machines on Mars which will be cheaper and won't risk anyone's life? 

To sum it all up, NASA shouldn't send humans to Mars, because of health and cost reasons. Martian germs will hurt us and our germ will harm Mars, humans will have difficulty surviving there, the trip to our neighbor will take up to 10 months, and the cost will be $1 trillion.
