You shouldn't change permissions for system directories wholesale.
Normally, programs and directories are world-executable but other
files aren't.
I don't know how you could recover your system from such an action.
You can remove world-writability recursively from a directory tree
with a command
chmod -R o-w <directory name>
This would leave permissions unaffected for the owner user and the
owner group; it would leave read- and execute permissions unaffected
for everybody and all targeted files, but it would remove
writability for users not in the owner group.
