There are many grammatical errors There are many grammatical errors in the book. It doesn't mention a lot of exceptions. So the students have a lot of questions and it's really difficult for the teacher to handle all of them.

Down the Tubes I have been a National Geographic member/subscriber for over 50 years. I read my parents magazines for almost 20 years before that. I will be a member no longer. I can no longer tolerate the racist, sexist bent of this once vibrant magazine. The editor has brought her lack of scientific background and personal prejudices to bear on her work--where it has no place. Every issue is has become a far left opinion piece instead of fact-based story with broad interest. Too bad.

The Nat Geo mag was once a venerated… The Nat Geo mag was once a venerated chronicle of people and places—no more. It has digressed into a pop culture social rag with issues found on every media site. Its become “Mother Jones” with an Atlas. Too bad! It desperately needs another editorial team in order to restore it former glory.

Inspiring Content, but hundreds of ads National Geographic Channel has been a source of awe-inspiring documentaries and educational content. It is my go-to channel to relax. The visuals are stunning, and the storytelling is both informative and engaging. However, the overall experience is marred by the excessive number of advertisements. The frequency and duration of ads interrupt the flow. Sometimes I even forget what I was watching 😀 I understand the importance of ads, but it would be good to balance how often you show them.

Subscription to spam National Geographic used to be a very respected journal. Now, they teamed up with Lindblad Expeditions. Once you subscribe to National Geographic, they sell your address to Lindblad Expeditions without asking for your permission, and you start getting catalogues of offensively expensive travel offers, tens of thousands of dollars per trip, from Lindblad Expeditions, and it is impossible to stop. Cancelled National Geographic because of Lindblad Expeditions spam. Called National Geographic for help to stop the spam. Looks like the spammers may be their partners. The frequency of spam got less but did not stop. Please, save your sanity and DO NOT SUBSCRIBE TO NATIONAL GEOGRAPHIC!!!
