Hi guys! Do you have time for a few quick questions? I see you're having a lot of fun. But do you ever stop and think if what you do is sustainable? And do you know what sustainable development means? Sustainable development is to make the world a better place for everyone now without destroying the possibilities for the next generations. If you wonder if something is sustainable you can ask yourself, can we do this over and over again forever? Sustainable development means that we need to keep three things in mind at once. Social progress, economic development, and climate and environment. First of all, we have to take care of our planet. We have many natural ecosystems that must be in balance in order for us to live here. The climate system is one of them. This system ensures that the temperature is correct and that the atmosphere emits exactly the right amount of solar energy. When we emit harmful greenhouse gases such as CO2, we clog the atmosphere. This changes the temperatures and earth which again affects our development. How we produce and use energy is incredibly important. Oil and coal are examples of energy we may run out of. Water, wind, and sun, however, will always be here. Using the lasting sources of energy that renew themselves is good for the planet and can provide jobs for years to come. Economics. Almost everything we develop by and trade starts with nature. The smarter we use our natural resources and the better systems we create for our fair distribution, the more sustainable we are. One way to contribute to a more and even distribution is to be more aware of what we buy and how it is produced. A football is a good example. It travels far before it reaches the football players. First, materials are made. Then, they print the logo somewhere else. Before a third country sees it all together. One single football sees the whole world before it reaches its goal. This journey ties us together. If we are to win the battle for a sustainable future, we have to play with fair rules that apply to everyone. Social progress. We humans are part of nature, but we are also important resources for the world. Just like water, the forest, and the sun. We have minds that can create the strangest and most creative things. But for us to be the best versions of ourselves, there are certain things that must be in order. Like having equal opportunities to education, safety, food, and medicine. This provides greater opportunities for us as human beings. But also for the planet, we just have to think in new ways. These three must work together. That is sustainable development. And there is actually a plan for this. All the countries of the United Nations have agreed on a joint plan for sustainable development. But for the plan to work, we need to cooperate and we need you to be on board. Are you with us? You
