Can we change the world?

Yesterday I was listening to Eric Clapton and I wondered if it really is possible to "change the world".

There are 7 billion of the people living on planet Earth and each day it seems that worsens.

I live in Brazil and, at least here, all houses have extra walls around them, for protection. It's so dangerous walking on the street at night, because you could to be robbed by a thief. I know that it is not only Brazil that is dangerous... other countries are dangerous as well. However, everyone has seen this and nobody has done anything.

I have a dream of a better world, however, it depends on the good heart of the people. It depends on people like you letting love enter their hearts and, through your good actions, to turn our planet into a good place to live.

I have a dream!

Hi Loren. I've marked grammatical, punctuation and spelling corrections in yellow, phrasing corrections in blue, and contextual word choices corrections in magenta.

I think the world is getting better very rapidly, though the really big changes do take lifetimes. However, in the age of the Internet, people have much more empathy for people on the other side of the world, because they've discussed things with them and played games with them. Also, as nations become more prosperous, people feel much less of a need to resort to crime. Here is a lecture of a fellow talking about how the world is becoming less violent over time https://www.ted.com/talks/steven_pinker_on_the_myth_of_violence?language=en
