Easy, Michael! Select the block of text from which you want to remove the paragraph marks, then open the Replace dialog.
Enter ^p as the text to replace and leave the replace with field blank or enter a space, depending on whether you'll need spaces where the para marks are or not. Replace All and you're done.

I would like to select a large section of text and then remove all the paragraph breaks, is there a way to do this?
