Growing Little Green Hearts: Why Sustainability Matters in Early Childhood

Sustainability is not something I “teach” at Wonder Tree in a formal way – it’s something we live together every day. Through my experiences as an educator, I’ve noticed that children are naturally drawn to caring for their environment when they are given real opportunities to take part in it. Simple routines like composting food scraps, sorting recycling, reusing materials for play, and caring for our garden have become meaningful learning moments for the children in my care.
Over time, I’ve observed how these small, everyday practices build children’s awareness of the world around them. Children love being involved. They take pride in helping scrape leftover fruit into the compost, carrying small buckets, watering the plants, and finding new uses for boxes, containers and loose parts. What might seem like a simple chore to an adult becomes a powerful learning experience for a child.
​

What I Notice in the Children

Through these experiences, I’ve seen children:

• Show a strong sense of responsibility and ownership over our environment
• Become more mindful about where things belong (what goes in the bin, recycling or compost)
• Develop empathy and care for plants, animals and living things
• Take initiative in reminding each other about caring for resources
• Feel proud when they contribute in meaningful ways

These moments tell me that children are not too young to care about sustainability. In fact, they are often more open and enthusiastic about it than we expect. When sustainability is part of their daily rhythm, it becomes normal, not something extra.

How Sustainability Looks at Wonder Tree?

At Wonder Tree, sustainability is woven into our routines and play:

• Composting:
  Children are actively involved in placing food scraps into our compost. We talk about what happens to our leftovers and how they return to the soil. I’ve noticed children becoming curious about what happens “after we throw it away” and asking questions about worms, soil and gardens.
• Recycling & Reusing:
  We reuse everyday materials for creative play and art. I often observe children finding new purposes for boxes, tubes and containers, showing creativity and problem-solving while learning that not everything needs to be thrown away.
• Gardening & Caring for Living Things:
  Watering our garden and watching plants grow has helped children understand that living things need care, patience and time. I’ve seen children form connections with plants in the same way they do with our animals – gently checking on them and noticing small changes.
• Nature Play:
  Many of our learning experiences involve natural materials. Children are calm, focused and deeply engaged when working with leaves, sticks, stones and soil. These experiences support both sustainability and wellbeing.
• Modelling and Relationships:
  I am mindful that children learn most from what they see. By modelling respect for our environment – turning off taps, caring for resources, speaking about nature with care – children begin to mirror these behaviours in their own play and routines.

Reflections as an Educator
Reflecting on my practice, I can see that sustainability is not just about environmental care – it is also about nurturing children’s sense of connection, responsibility and belonging. When children are trusted to take part in real tasks, they feel capable and valued. These experiences support their confidence and sense of agency.
I have learned that sustainability in early childhood doesn’t need to be perfect or complicated. It grows through small, consistent actions and through relationships – between children, educators, families and the environment we share.

Planting Seeds for the Future

My hope is that the children who spend time at Wonder Tree carry these small habits with them – noticing where their food scraps go, caring for plants, reusing materials creatively, and seeing the natural world as something to be respected and protected. These early experiences may seem small, but I believe they plant seeds for how children will care for their world in the years to come.
At Wonder Tree, sustainability is part of our story – lived, felt, and grown together, one small moment at a time. 🌳​
