What counter-claim is found in the Climbing Space speech?

ah, shun the horrid gulf! by scylla fly.

i would say that it is a bad thesis because it doesn't explain what the health risks are. it seems to be a very vague thesis statement. thesis statements need to set up for the entire essay. it needs to give the reasons why people need to stop drinking diet soda.   so, i would say that it is a bad thesis.

hope this
