Will there be a diffrence if animals didn't exist? (it's not health just a question i had )

For humans, there would be a huge difference. Most plants would be forced to change as no insect would exist to pollinate them and no animals would exist to help spread their seeds. We'd all have to be vegetarians as well, since meat wouldn't exist (other than human flesh). The ocean would be terrifying as well, since it'd be empty and dark. All in all, earth would probably we screwed.

Yes, there would be a huge difference if animals did not exist.
