To effectively finish her concluding paragraph, Lisa can use the call to action method. Here’s a revised version of her concluding paragraph with an impactful closing statement:
In conclusion, adopting a shelter pet offers numerous benefits. Not only does it help combat the issue of animal homelessness, but it also provides adopters with a loyal and loving companion. Furthermore, the health and financial advantages of adopting a vaccinated and spayed or neutered pet cannot be overlooked. I encourage everyone to consider visiting their local shelter and opening their hearts and homes to a pet in need. Making this choice not only changes the life of an animal but enriches your own life in ways you've never imagined.
This closing statement not only reaffirms the main points of the essay but also invites the reader to take action, making the conclusion more compelling.
