I think you might have to wear important equipment to survive on mars. Precautions that I think you might have to make is trying not to take in bad fumes. I say the biggest challenge would be just living on a new planet and getting to that new planet.

I will float.The precautions will be to have oxygen.My biggest challenge will I be able to survive.

It would probably be cold and have no gravity and we also wouldn't be able to breath. We would have to wear a space suit and when your angry you would want to jump and you just gone to have to fly or stay off the ground.

If humans could travel to mars it would be a bad vibe. There in mars it has a red sky while earth has a blue sky.you would see a massive valcano.You also can see a gigantic whole that can stretch from New York to California. You would also have to adapt to the wether because the game ether there is colder because his spot on the galaxy is further from ok the sun  unlike earth it is closer

don't go outside the border. be careful

Life wouldn't really be that good because there's no plants or animals on mars. The precautions they would have to take is a big supply of food and water and other supplies. The biggest challenge would be the fact that mars has no oxygen.

Life on Mars would be hard because if u bring any thing it would flight away we wouldn't be able to breathe. The precautions would be always wear a helmet and we have to do everything in a space ship. The biggest challenge would be eating with it floating and spilling on the floor.

I think that people will take things there not meant to take.Life will be hot so I don't think there will be life on mars an we will have to wear a conducter suit.

Life there would be hard. We would need to bring water, oxygen and food. The biggest challenges is the survival.

# data[].attributes.body
Life would be different. I say this because we would have no air when we go out. Where are the food and where are the stores and stuff cause were not going to have any way to go to the store and that’s just tough.

# data[].attributes.body
If we could live on a different planet then we would probably have to quarantine because we don't know if other viruses can exist on these planets and after that if we want food we would have to get a resupply ship to bring food once every 3 months if we wanted to go outside then we would have to get personal space suits made. All of those things seem like too much to me.

# data[].attributes.body
i think life would be weird because they may have to do somethings before they move there you would have to put on maybe some face protection

I don't think that life would really be that different because i heard that they are building cities there. I feel like the biggest challange is getting used to there being no plant or animal life, but hey at least the sky is pretty. Zaniah Belcher

I think life would be fun you have no gravity it would be like your own trampoline. Some precautions you would have to take is wearing a suit so you wont die because there is no oxegeyn in space.

# data[].attributes.body
It would very dry that its probably not alot of water food and water.

# data[].attributes.body
I would stay here the oxygen is and I would try to find water.

if humans moved to mars in 2030 it would probably be bad because on mars its cold and mars has dust and dust storms and because its cold wind is probably blowing the dust everywhere precautions i would have to take is to stay away from somethings because they could make you sick i think the biggest challenge is the dust

# data[].attributes.body
If humans could move to planet mars I think life would be different how do we know if things we need are available there.Some precautions that you would have to take is to watch your back and also be safe.The biggest challenges would be that gravity low there and also cold jaw dropping temps.

# data[].attributes.headline
i would say that life would be very hard I say this because there or no food resources on mars or no shelter for us to live in so when or if something was to happen then we would have just been out in the open and it would be hard to escape for it

if people lived on mars then they would be hot everyday no cold christmas

I think if we could moves to Mars or another close planet it would be good and there it could be split pollution , on earth if would be as much people and therefore there would not be that much pollution and it could be peace in the world and a lot more space to build in the world.
