My name is Ruth and I am the Deputy Head Student for Eco and Sustainability. Through this role, I have spent a lot of time thinking about what sustainability actually means.
Often, when we discuss environmental issues, the conversation quickly turns to technology: renewable energy, electric vehicles, carbon capture, biodegradable packaging and so on. These innovations are undoubtedly important. However, I have increasingly come to think that one of the greatest challenges facing sustainability is not technological at all; it is cultural.
Most of us are already aware of the environmental issues we face. We know that single-use plastics contribute to pollution; that fast fashion creates enormous amounts of waste; that reducing consumption is often better than simply replacing products with newer “greener” alternatives. The difficulty is not a lack of information but changing habits and expectations that have become part of everyday life.
This becomes especially clear when we think about clothing. Fast fashion has made it normal to view clothes as temporary rather than long-lasting. New trends appear constantly, and it can sometimes feel as though we are encouraged to replace perfectly good items simply because something newer has appeared. Yet one of the most sustainable choices we can make is often the simplest: continuing to use what we already own. Buying second-hand, repairing clothes or passing them on to others may not seem revolutionary, but collectively these choices can have a significant impact.
This is something I try to apply in my own life; whether that is choosing second-hand clothes, avoiding unnecessary purchases, or using reusable alternatives rather than single-use products. These actions can sometimes feel small, but they are reminders that sustainability is not only about large global changes, but also about the choices we make every day.
The same principle applies within our school community. Sustainable period products, reusable bottles and reducing single-use plastics are all examples of changes that are already possible. This year, I hope we can build on the success of our preloved clothing sales by making sustainable choices more accessible and normal. We could explore more regular second-hand sales, encourage clothing swaps, and continue conversations around reducing waste rather than simply managing it.
Schools are uniquely placed to influence this cultural shift. In Japan, for example, students often take responsibility for cleaning their own classrooms, helping to build respect for shared spaces and a stronger sense of community responsibility. While sustainability will look different in every environment, the idea behind this is important: when people feel responsible for the spaces they inhabit, they are more likely to care for them.
While large-scale environmental problems can sometimes feel overwhelming, meaningful change often begins with relatively small decisions. Sustainability is not simply about developing new technologies; it is also about reconsidering how we live, consume and interact with the world around us. The future of sustainability at Blackheath High depends not only on the innovations we create, but on our willingness to rethink the habits we have long taken for granted.
