13 “Trees are the best investment in the future of our city,” Ms. Hayes says. They provide many environ- mental benefits that she says are needed more than ever because of climate change. Trees help keep the air clean, which is good for people with asthma and other lung problems, Ms. Hayes says. They also provide shade on hot summer days, so people do not have to use as much air conditioning. Ms. Hayes says there are studies showing that trees even create a more peaceful environment, helping to lower stress and reduce crime. “We should be happy to plant trees,” perhaps to mark the birth of a baby or move to a new home. “If you ever plant a tree, you will never forget it.” She urges people to be respectful of trees because they are important for both humans and animals. “Don’t do harm to trees,” she says. “If you see a young tree, don’t swing on it and break a limb.” Another of Ms. Hayes’ jobs was to pick out the towering tree that was lit up outside City Hall during the 2018 holiday season. She found the 70-foot-tall white fir in Horning, N.Y. “I was there for the takedown,” she says. Ms. Hayes says she likes to use her middle initial because it offers a hint of how her life has turned out. That “M” actually stands for “Maple”—one of the many types of trees she admires. — By Aaliyah Mendez, Andrew Puhiera, Cornelio Rodriguez, Alyany Santos, and Hailey Torres St. Veronica Healthy Hero Illustration by Kamaiyah Brady, eighth grade, St. Martin de Porres Healthy Saint Ways trees help create a healthy environment •  Reduce air pollution. •  Provide cooling shade. •  Reduce water runoff, helping to prevent flooding. •  Provide a habitat for birds and other creatures. •  Produce nourishing fruits and nuts. •  Create a sense of calm and well-being. •  Encourage people to walk and play.
