invisible children

we had lately a documentary night with the international student fellowship
some of my friends started
showed the movie "invisible children" which is basicly a documentary made by 3 young american guys just going to sudan and north uganda to figure out what happended with all the children soldiers there,- they did it without experience, without any organisation and they met hundreds of forgotten kids, hiding every night in busparks to sleep in fear of getting abducted by rebellforces
they didn't want to be the people who will also forget them and started a movement called "invisible children" to mobilise people just not to forget

one of many things i thought at first
how much do i fight for justice?
in the discussion afterwards we found out that actually not many of us ever got involved in things concerning social justice.
I remember the passion i had as a little girl for all kinds of environmental and social things, i would fight my dad as he tried to cut our trees. My friends and i would get so upset about local trashed areas, commiting ourselves to "save" those.
This is still there, in all of us i think. Somehow i feel sometimes I read and studied so much about unbelievable and unacceptable things that i grew so fat of all this knowledge that i can hardly move, - act on it. Is it not our responsibility to raise our voice about every topic we get to know about, which is injust? But often just a feeling of helplessness, not knowing what to do or what would be the right thing to do is left.
....Either the professionals take care of it, yes it's terrible but we can't do anything about it anyway, we have to focus, daily life took it over, we got all used to it ...
I do feel capable of doing smaller things and we should not forget doing those, like Resa is often pointing out on her blog.
What about the big things? In Darfur, Sudan 200'000 people got killed since 2003 and millions were displaced. In an article from IRIN they say that besides that of course the government and rebelgroups have to agree, more international pressure is needed that the situation for the people will not get worse. Since last year december the situation also got more dangerous for the NGO's. I don't understand this conflict. I've been ignorant towards it most of the time.
I have no solutions. But haven't i also been convinced that i would act against ethnic cleansing out of all the history lessons? Not because i have a "special heart" for doing it, just because it has to be done. Because these are people made in Gods image.

Aren't we the international pressure?
How can we put more pressure on our governments to act more this issue? What can we as non-politicians do?
