Drew sounds like hes indulged in some contemplation of life and the universe and has found the beauty and diversity of all we know so far of the undeniably magnificent universe we exist in to be surpassed by the present earth and its history, notably the life it supports but also the oasis and miracle that it is.
He feels that its necessary to fight to restore, maintain and continue this utopia we exist on.

I think while people believe its necessary to fight, no matter how just and commendable the cause, peace will allude us.

However I'm intrigued with his final mention of integrating social justice and ecology and would like to understand more what this achieves and how to set it in motion.
Over all, I found it an interesting introduction to the topic of slavery.

Criticism
To me it seams like he stumbled around on the way to his point with unnecessary stories and poorly presented explanations with awkward pauses, uncomfortable body language and did he tap the microphone hes wearing when he was talking about getting nervous? Tsk tsk.

The things i do after a joint lol.
Peace,
