My solution is address the challenge by using rules of making sustainable and zerowaste environment; we can teach peoples for this.
By making the way for peoples to use sustainable vegitaion(nature) use.
In the other hand making zerowaste environment and making this environment have a role in order to make a zerowaste city then country, continent, even though it's easy to make zerowaste earth.
Carbon free transportation is the other most important most important thing that we need to think.
And, we need to thing more about factories!!
