Sorry, but I don't see that at all in the poem; Page is just saying that we have to work hard to take care of the earth– at least as hard as we work to keep up our own homes and raise our own families. It is a very homely poem. However, if that is what you wish to assert, I can fix your thesis statement: Rather than suggesting what needs to be done to preserve the earth, the poet is questioning our negative human attributes: selfishness, isolation and ignorance.
