    My MCAT is already this weekend and since I graduated with a business undergraduate course, I have little to no background with Organic Chemistry.
    Having watched your Organic Chemistry series, I have learned so much and even though there's a lot more to it, I'm finally understanding more of the notes I've been reading since I'm learning Org Chem all on my own.
    Thank you so much for this series!

      By your logic the following is true:
      Carbon is an atom.
      I'm made of carbon.
      Therefore, I am an atom.
      This is a fallacious syllogism. At best you can say that ***** is made of tramps.

    Dear Hank,
    First of all, many many thanks for this marvelous video. I have to say, it has helped me tremendously in the understanding of a certain matter I am deeply concerned about and it also has helped me link several unattached concepts in my head. Also, I wish I had discovered Crash Course when I was in high school, it would have helped me inmensly, either way I love the way you and team make the topic introduction so easy to understand and of course, the beautiful graphics of Thought Café and the sound team :')
    Million thanks from a quite slow College Student.

    Why is this comment section full of climate change sceptics?

      Maybe because of all the morons who think there was a time when climate did not change.

      Because cuntservaturds hate hearing hard reality & hard necessary truths. They want to live in their fantasy bubble where there exist no consequences to anything, to any of their habits.

    With that well said the solution to our ever increasing CO2 volumes is to raise more gardens and drive less. If we had more gardens we would drive less to the jobs because food would be our number 1 provision already taken care of right outside our doors within walking distance. PICK AND EAT! More trees means more O2 produced and more absorption of CO2.

      While I haven't really learned anything new from this video, the whole topic of the carbon cycle and it being out of whack in recent centuries is not only interesting and fascinating to me, but also incredibly scary.

    While I love this channel, and mostly like this video, I'm finding it hard to actually 'like' the video. You failed to explain properly the different types of cycles and how their cyclical rates vary. Most importantly you failed to explain why this is important for the whole fossil fuel issue, being part of one cycle that does not naturally bleed into the other so quickly, as we are making it do. I feel that the way you lumped them together will lead people to believe that there is far less of a danger than is actually there. The relevant importance of this makes me very disappointed, Hank. >:(

    Favorite chemistry episode! Great series, Hank. It may not have a lot of views now, but kids will use this resource for years and years to come. Also, as a 21 year old humanities grad student, this is accessible and interesting. DFTBA, homie.
