people save money, go to some poor country, make a lot of hot soups, share our heart with poor children who have to work every day for food. An idea from Nguyen Ngoc Duy

I think we should share our heart with children, they have to work for food everyday and live without care. They may feel lonely, I know some children like that, they have only one dream is that someday, they will have a family, someone care about them. I know this world is not equality, but what I want all the time is to make it smaller. I think if you want to make this world better you have to make people living better first.
if you have a same idea with me, say yeah :d

Yeah! On improving peoples lives and improving the world! :-)

Practically I ask (since this website gathers ideas to execute for next month): shall I go to a third world country next month and make lot's of hot soup?

i believe that really helping people in poor countries lays not in solacing people by giving soup and share our heart with their children. It lays merely in helping people to educate their children, by removing unfair international trade regulations (that favor developed countries), support the countries by becoming more democratic, in other words to remove the inequality.

Thanks Maarten.
About Bart's Idea, I think your idea is correct, but it's too big for us now, we don't have enough ability to do it, how can I do it. I want we begin from small thing first, if there are something I can do for children to make they better, I promise with you I will try my best.
Thanks for your comment :)

If we do this, we can have time together to talk about how to make this world better. we also understand more about people, what are they expect, how they dream about themselves in the future. Together, we can change this world, make our life more meaningful. I always expect that one day, I'm in a team, a team with people who really love this world, who want to change this world with me. This is my dream, and I will never give up on it. I'm a system developer in Denmark now but I'm a Vietnamese, I come from a poor country, then I have seen a lot of pitiful condition, but I don't have money to help them, it hurt me a lot. I known this is very hard, I can not do it by myself, I need more help, I need more people. I'm waiting for that day, if you have a same idea with me, please contact me, I'm waiting for you. I have nothing except my dream.

I agree that what I say is way too big and difficult. But at least to begin with (and this is a call to everyone) put your vote where your mouth is.
It doesn't matter what you think of Europe, but it is the place where really a lot of international trade regulations are being made. So vote for parties that try to bring equality to trade regulations.
And put your money where your mouth is too.
These are problems that are much more complicated and highly abstract compared to a lot of issues that are being dealt with on this website, but i sincerely believe that these kind of issues are very very important.
A big role in international trade is ofcourse for big companies (Nestlé, Shell, Unilever, P&G, etc). We should encourage these companies to work as sustainable as possible - not only focus on sweet & small local production. Those small scaled initiatives are simply not able to feed the world, not even if there where multiples of them. We need those arrogant, unfriendly multinationals, we can't beat them, but we can change them.
This is for example done by this organisation http://www.idhsustainabletrade.com/

I know what you know about this world is much more than me, and there are a lot of ways to help this world better, a lot of different ways. I think that everybody in this world is doing this, everyday, they go to work, that mean they help this world, make this world better. Some of them have a big ability to change this world, they create something amazing, create robot to serve people, create computer for helping our life better,... But are you sure it help everybody in this world, every single one. Do you know how many people in this world die everyday because they don't have anything to eat. If they don't have anything to eat, will they pay attention to anything else? anything like computer or robot. Is that fair? Is that fair when you have a family stay with you every night in your warm house while some people have to work to midnight, maybe later. Have you ever pay an attention to them. Is this because they didn't study hard when they were young, Is this because they are so stupid, they don't have enough ability to get a job to feed themselves. No, I don't think so, it depending on their country, their country policy or maybe war or maybe earthquake or something, a lot of things make it happen. I don't know how to help them, but if I decide to do something, I will focus on them, I think I don't have to care about the others because I think they are so happy now.
