Moss is often seen as an unwelcome invader in our gardens, roofs, paths, and patios, prompting us to spend time and money trying to eliminate it. But have you ever considered the crucial role moss plays in our ecosystem? When we think of the Earth’s primary source of oxygen, many people instinctively mention trees. However, the truth is that moss, including aquatic algae and terrestrial moss, contributes significantly more. In fact, moss produces at least five times more oxygen than trees, with just one square meter of moss generating more oxygen than ten mature pine trees.
So, should we really be removing the moss that grows on our roofs? While it may seem damaging, moss lacks roots and stems, deriving its nutrients from air moisture and photosynthesis. Rather than harming your roof, moss can actually provide insulation, keeping your home warmer in winter and cooler in summer. In contrast, the high-pressure water used to clean roofs can cause considerable damage.
As awareness of moss’s benefits increases, more scientific research is being conducted. Notably, Paolo Bombelli, a biochemist at Cambridge University, has developed an innovative technology called biophotovoltaics (BPV). Student Elena Mitrofanova at the Institute for Advanced Architecture of Catalonia has leveraged this technology to create MossVoltaics, which are walls of moss installed on building exteriors. These moss walls are not only more affordable but also more sustainable compared to traditional solar panels. In urban environments, this eco-friendly solution offers a promising way to meet our energy needs.
Another fascinating initiative is the City Tree project, launched by the German company Green City Solutions. In 2018, they implemented this project on Glasshouse Street with the support of Westminster City Council and Evergreen Systems. Designed as urban furniture, the City Tree serves as a bench while effectively combating pollution. Remarkably, it can absorb the same amount of air pollution as 275 trees, yet it occupies just 1% of the space those trees would require. This innovative solution is being rolled out in other European cities, including Paris, Amsterdam, and Oslo, with the goal of creating a sustainable approach to air quality.
Lastly, we can all incorporate moss into our lives through indoor moss walls and ceilings. As horizontal gardening gains popularity, live moss is often favored for its aesthetic appeal. However, preserved moss that maintains its color, texture, and appearance without care can also enhance spaces like offices, restaurants, schools, plazas, and foyers by absorbing noise and airborne particles.
Protecting moss is just as vital as protecting trees, especially as sustainability becomes increasingly important. What we once viewed as a nuisance is actually a valuable asset. If we aspire to create a more sustainable environment, we must reconsider our perceptions and actions toward even the smallest elements of nature. As Albert Einstein wisely stated, “Look deep into nature, and then you will understand everything better.”
