We have humanity, the earth and institutions. Can we put them together? It would require that human use institutions to manage the three together.
One key problem is the tendency of the rich among the humans to try to marginalize a large proportion, maybe 1/3 to 1/2, of the population as being, in the current market driven debt milking world, many people who are consumers but not producers.
In current circumstances we have systems that need to change. Some are
Land ownership and use
Support for parenting
Preauction if essentials for all
Distribution of essentials to all.
How do we get these to change? All at once while working on each. But most people will try to prevent change on the idea that yesterday was better than tomorrow is likely to be.
