Melissa McCollum, author of MY HAPPY EARTH, presented animal bio-facts from the 5 major biomes to guests of the Fort Worth Museum of Science and History during their All Systems Earth event April 18-20, 2017. Children learned how human activity affects each animal’s habitat and health, and learned how to implement the 4 R’s (Reduce, Reuse, Recycle, Re-buy) to protect their environment.
