Tokyo is a very polluted city. We will be talking about how we can change this
We will have a strict recycling system, and will have a compost section for organic matter. The compost can be turned into fertile soil for locally grown produce that will be grown atop the buildings
For starters on how to help, waste disposal
What about things that don't fall in that category?
Great question .For that it will go to an incinerator and the heat that comes from that incinerator can be used to make energy
Other sources of energy will include geo-thermal since its near volcano activity and such as well as nuclear since its relatively clear
And for food each building will have rooftop gardens to provide more vegetation in the city and more food. The compost from the compost yard will be used in the gardens as well
Lastly we will have next to free transportation, electric busses, that will get their own lane so that they are faster. Similarly there will be a bike lane and a sidewalk, lastly there will be one car lane to de-incentivise driving
