Change the World

Hello, today i am going to talk about the ways to change the world. Everyone have different ways to change the world, to the perfect utopia in their mind. 

I think that the key to make the world utopia is to prevent war from happening. The competition between person and country is getting more and more. People compete with each other on work, on study. Same as countries. Country compete each other on military, space and economy. These competition may cause conflict, even wars. 

The way to prevent these things happen is that every country be friendly to each other. Instead of compete, we can share our new inventions or product with other countries.
