Wich action would most likely increase the amount of carbon in the environment

Cutting down trees

Explanation:

Of course this is just my opinion, but stopping the production of oxygen can greatly effect the carbon and oxygen ratio thus, increasing the level of carbon in the air. There are many different ways for the increase of carbon to take place but I think that cutting down trees has a major effect.

you did not attach the discourse, but i assume it to be the discourse on the origin and basis of inequality among men (the original titile in french is: "discours sur l'origine et les fondements de l'inégalité parmi les hommes"), also know as "second discourse". in this discourse, jean-jacques rousseau emphasizes that private property is the basis of all inequalities.

therefore, what enabled the old regime to maintain as long as it did was private property.
