Time Travel

I like travel to the future, maybe 50 years in the future, but I would like to return to the present, because the climatic change probably finished with life, or maybe not, so I would like watch the world.

Then in 2072 I think we have two futures, or we didn't learn anything, or we did something with the environment, in the first case, obviusly I return to the present inmediatly because I don't wanna die for lack of water, but in the second case I would stay some years learning, learning about the medical advances, it was possible to cure some diseases? Such as cancer, and What happened with the pandemic? dissapear? We all need to get vaccinated once a year?

Perhaps organ cloning will be possible and we wouldn't need another humar for a transplant or maybe be possible heal to the diabetes, or other diseases or conditions that today they not have cure. 

And traveling, maybe we'll be able to go con vacation to the moon, or travel to Europe or Asia its more fast and cheap, I'm particulary interesting in the transport to other countries be cheaper, because now I would like to visit many countries, but its too expensive. 

I don't know what happen in the future, but I'm really wish in the future we let's take care of the environment, and the society is better.
