Stop War

Nowadays wars are a problem that affects both our life and our wold globally. It's a problem that has existed for lots of hundreds of years, but in consequence of the important improvements in weapons (fire weapons, nuclear weapons...) it has became much easier and efficient to kill more people with less effort.
Most of the people suffering from wars are those who do not have the way to protect themselves from attackers, and this usually coincides with poor countries or those that are also named as underdeveloped.
Some of the main reasons for wars to start can be religion, race or (of course) money. Important people of the richer countries are the ones who take advantages from war, and the media usually tries to hide the horrific things that happen in other countries, so as they are far, and we are not shown what's happening but we have to look for it to inform ourselves appropriately, we tend to do as if nothing was happening.
I think that the first thing we should do to stop wars it's to concern people about what happens everyday in our world, and after doing that, show them that if everyone made a little effort we could make a big change.
