Text goes out of bounds [duplicate]

Question

I am having a problem on the appendix part of my research paper because the text starts to look like this

The following is the code snippet that generated the line:

\bibitem{featureEngineering}
Discover Feature Engineering, How to Engineer Features and How to Get Good at It
\url{http://machinelearningmastery.com/discover-feature-engineering-how-to-engineer-features-and-how-to-get-good-at-it/}.
