There are many, many ways to spread peace. But at our age (<18 year) isn't it always easy to spreading peace, because nobody listen to children. So we have to spread peace at our level: you can be very nice to friends and never fight with them. That doen't help very much but all the little bits count. There are also special foundations which spread peace. Such as 'National Peace Foundation', 'Worldpeace is possible' and 'UN Messengers of Peace'.That are people who believe in the goodness of the people over the whole wide world. These are just a few foundations, there are a lot more foundationtions to. There is olso somethething like 'The Day of Peace': every year, people in all parts of the world honour peace in various ways on 21 September. And this already of 1981. So you see that there are a lot of ways to spread peace.
It's wonderful to know that there are people who are fighting against war and who are trying to help our earth and all the people. That's why Alfred Nobel invented the Nobel prices for outstanding achievements in physics, chemistry, medicine, literature, and for work in peace. This year there was an organistaion and a person who chared the Nobel price for peace. Intergovernmental Panel on Climate Change (IPCC) and Al Gore won the price for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change.
