Here’s a way to fill in the organizer for Lisa's essay on adopting a pet:
Overall Topic: Adopting a pet from a shelter or rescue
Main Idea: Adopting shelter pets provides numerous benefits for both the animals and the community.
Point #1: Adopting shelter pets can help save the animal’s life and give them a second chance at a loving home.
Point #2: Adoption helps control pet overpopulation, which is a critical issue in many communities.
Point #3: Adopting from a shelter is often more affordable than purchasing a pet from a pet store or breeder.
Combine the main idea and points 1, 2, & 3 to create a thesis statement: Adopting a pet from a shelter not only saves a life and reduces the problem of pet overpopulation, but it also offers a more cost-effective alternative compared to buying from pet stores or breeders.
