"My parents taught me to think of what happens after we use things and the the ripple effect when we use plastics and oils that are bad for the environment," the 13-year-old Charlestown high school student said. "I use Keep Cups and instead of wrapping my sandwich in cling wrap I use reusable wraps or containers."

Ms Hubber features in the 75^th anniversary campaign of the Greater Bank, and was on hand on Friday when the Newcastle-founded bank marked the occasion by launching a "legacy project" that will see 75,000 trees planted across regional NSW over the next year. Around 45,000 trees and plants will be planted in Newcastle, Lake Macquarie, the Hunter and Port Stephens, while the remaining will be planted across other regions within its area of operation.

Greater Bank CEO Scott Morgan said that the tree planting projects were symbolic of the role the customer-owned Bank had played in growing together with its communities over the past 75 years.

"It was important for us that in celebrating the milestone we contribute to a cause that is important to our customers," he said. "The need to protect and nurture the environment was a consistent message delivered by customers across our areas of operation."

"The trees will not only provide these communities with an ongoing legacy to mark this milestone, but as they grow, they will provide an enduring symbol of our commitment to social responsibility and sustained support of local communities," Mr Morgan said.

Ms Hubber believes everyone has to do their bit for the environment, including business.

She said it was important that businesses gave back to communities and "cherished their lands" rather than just focusing on their profits.
