Life is growing faster and faster every day. It is normal when each person has their own car and this causes pollution in lots of aspects for the environment. Due to technology development, I think we should use SkyTrans instead of private transportation. Firstly, it is speedy, you even just need a few seconds to go anywhere you want. Secondly, it is safe for the environment because it does not exhaust a lot of emissions into the air. In conclusion, SkyTrans need to be developed in the future to provide the best things for human.
