I'm of the original Live Aid generation. I supported it for years and, despite what people's feeling are about Geldof, the charity is still going, doing what they do! They do their best in a world that is hardly ever fair, where being fair would make a huge difference!
They started doing everything wrong, much of the money went astray, lined the pockets of already rich dictators. Lots and lots of mistakes were made. Lots and lots of money as wasted. They are slowly, very slowly, getting somethings right, but they still fall down and fail to deliver.

Sadly you can replace the name of the charity with almost every other well known aid giving charity there is and get much the same story. Same errors, same waste, same inability to make truly meaningful changes.
So nowadays I look at those pictures and think "Why am I being asked again? I know if I donate the money will be wasted, that child and many others will die"
It is not good enough for anyone to shout anywhere "What are you doing whilst these children starve?" What you need to do OP is lobby your MP, get them to raise questions in The House. There has to be a fundamental shift in charitable thinking for any meaningful changes to be made.
DO NOT join one of the many charity activist groups who are trying to make governments apply sanctions, trying to raise awareness and shame politician in many countries - that is a pointless exercise that only the very naive undertake for long.
DO research smaller charities that work in smaller areas, supplying a specific 'thing'. They are many and varied, you will find a couple that make perfect sense to you!
I used to support Tractors for Africa. It was a college wide choice: students rebuilt old tractors and sent them to more arable based areas across Africa. Some students went over to see what happened and they learned how Africa farmers maintain machinery using coca cola cans!!!!
I also used to support a well known water project, but stopped when I realised the lack of continued funding. So now I support African Medical and Research Foundation and Farm-Africa, who focus on sustainable solutions.
I also support a local rapid response charity, Rapid UK/International, mainly because I know someone who works with them.
And I don't forget the children in the UK, I volunteer at a local food bank.
As others have said, do the small things you can see make a difference!
