Every day we can see the effects of climate change caused by Earth’s inhabitants. As world leaders and scientists look for ways to slow, stop and reverse the damage being done, we found three cool dog people who teach us how dog owners and their pups can help in the fight.

The steps it takes for a dog to find his perfect adopted family forces him to rely on a number of different types of loving humans. Sophie Gamand, Lisa Lemieux and Bobby Humphreys are three such people.

Jesse Freidin, Lili Chin and Dr. Marty Goldstein all had dog-related careers that taught them the importance of the bond between a dog and his owner. They harnessed this knowledge and found a way to share it with others through books.
