Perhaps you should try some spelling variations:
decrease their » increase their (Expand search), decreases the (Expand search)
their wasting » their eating (Expand search), their writing (Expand search), their nesting (Expand search)
decrease the » decreases the (Expand search), decrease in (Expand search), decrease of (Expand search)
the decrease » to decrease (Expand search), and decrease (Expand search)
decrease on » decrease in (Expand search), decrease of (Expand search), decrease or (Expand search)
on decrease » on decreased (Expand search), or decrease (Expand search), of decrease (Expand search)

You may be able to get more results by adjusting your search query.

• Removing quotes may allow a broader search: (( decrease _ decrease the decrease ) OR ( decrease on decrease their wasting ))~.
