Hello Sofie
I think rats will always exist. At least, as long as there is dirt,
war, rain-pipes and so one. And if all this things won't exist
anymore, rats will find other things to live of. Rats are no weak
animals, they are small but somehow they always survive, even despite
of all those eradicators.
Also poverty will never disappear I think. The gap between the rich
and the poor still grows, it will be very difficult to make it
smaller. As long as the rich have all the means, and the poor have to
fight to survive, things will be the same. Money sometimes means
power, so they can decide things in their own advantage. They have a
good life, so why would they help the poor? Of course it's not a good
mentality, but I think it still exists somehow, and we can only hope
that it disappears, and that the poor get some better chances to
improve their life.
Wartime will not disappear immediately too. I don't think we will have
a new world war, or not a war from man to man. The trenches, that's
the past. Now they can fight from America to Russia without seeing
each other, but of course there will still be a lot of victims in case
of a new war.
Kind regards
