My idea to create a better world and a sustainable tomorrow, is to make bus and train tickets cheaper or free. Then more people would take the bus or train. That’s better for the environment, because then carbon dioxide emissions would be lower. A research study proves that – on average – a car has just 1.5 occupants even when many people are taking the same route, for example, to work. Another idea is to have more advertising for the solar panels. Many people don’t know that every household could have solar panels on its roof. However, this costs a lot of money, so if the state subsidised some of the costs, maybe more people would get a solar plant for their houses.
