As I can guess the planet will be colder. It will be an Ice Age in the nearest future.
I think everybody will watch TV programs whole day long.
In future there won't be politicans. Robots will manage countries.
People will dress very warmly, because there will be an ice age.
Sport will be distributed as it is now. Perhaps there will be new kinds of sport.
Medicine will be much better, because thanks to technology people will learn to treat serious illnesses.
In conclusion I want to tell you that I belive in future people will be kinder and more huppy. :-)
