live peaceful (living without fear)

in 2040 I want to live in peaceful world where I am not afraid of plane's sound over my house, where I'm not scared that my neighbor country invade in my homeland. I strongly believe if we change our mindset we can change the world too and solve obstacles without fighting and killing each other. In my ideal future, people won't become refugees, they won't lose their homes and loved-ones. They will be able to live without fear. Personally, I have relatives who are refugees, who lost their home forever, have big unhealed trauma and I reckon this fact gives me motivation to work hard to change the future and give them better life. In 2040 people will already get the fact the humankind need peace and we will live in the world where everyone will be equal(I mean equal in all aspects), will have good education, will care about nature. The world hunger won't exist anymore, but I'm inclined to believe that this is really hard to achieve if we are realistic, but I know my generation will work hard to be close to this version of future
