You are not giving any more evidence or another point, you are just stating an opinion.

Irrelevant Conclusion

A smiley face isn't an argument.

Rich countries must stop foreign aids to poor countries.

Helping the poor won't solve the problem of hunger. Even if the aid is in the form of helping countries increase their resource production (e.g. food), the central problem of ecology (i.e. excessive demand of resource) won't be solved. The central problem of hunger is overpopulation.

Irrelevant Conclusion

Helping the poor has nothing to do with overpopulation.
