You probably searched for shade this summer.
You closed the shutters a little earlier. Carried a water bottle everywhere. Checked the weather before deciding whether it was worth going outside.
The headlines have been difficult to ignore. Across Europe, another period of extreme heat reminded us that European heatwaves are becoming a defining consequence of climate change.. Streets emptied during the hottest hours of the day, forests closed to visitors, and many of us found ourselves searching for shade, water and a welcome breeze.
And that is in Europe. While we could retreat indoors or turn on a fan, not to mention what happens around the globe or even, in nature where there is no such option.
For birds raising chicks, wetlands slowly shrinking beneath the summer sun, insects emerging out of sync with flowering plants, or forests already under pressure from repeated droughts, extreme heat is more than uncomfortable. It is a growing challenge that affects entire ecosystems, often in ways we cannot immediately see (IPCC, 2023; EEA, 2024).
Climate change can sometimes feel like an abstract concept, measured in graphs, statistics and future predictions. Yet the reality is unfolding quietly around us. It is in the earlier flowering of wild orchids, the prolonged dry riverbeds, the changing arrival dates of migratory birds, and the increasing frequency of heatwaves that are no longer considered exceptional, but unfortunately expected.
The good news is understanding these connections reminds us that our choices matter. And perhaps one of the most powerful ways to reconnect with nature is simply by spending time in it.
Nature is a network, not a collection of species
When people think about biodiversity, they often picture a list of rare animals or endangered plants. But biodiversity is much more than that. It is the intricate web of relationships that allows ecosystems to function. The connection between European heatwaves and biodiversity loss is becoming increasingly clear.
A wetland is not simply a home for flamingos or herons. It stores floodwater during storms, filters pollutants, replenishes groundwater, locks away carbon in its soils and provides feeding grounds for thousands of migratory birds. Likewise, Mediterranean forests do far more than offer scenic hiking trails. They regulate local temperatures, stabilise soils, support pollinators and create habitats for countless species, many of which exist nowhere else in the world (IPBES, 2019).
Each species plays its own role. Pollinating insects support the wildflowers that sustain butterflies and bees. Native shrubs provide berries for migrating birds. Birds disperse seeds, helping forests regenerate naturally. Predators regulate prey populations, maintaining ecological balance. Riverbeds pave their way through the mountains, allowing nutrients to travel. Remove enough pieces from the puzzle, and the whole system becomes less resilient.
Science describes this as ecosystem resilience: the ability of nature to absorb disturbances while continuing to function. Healthy, diverse ecosystems recover more easily from drought, fire and disease than simplified or degraded ones (Oliver et al., 2015).
The Mediterranean is warming faster than many regions
The Mediterranean Basin is recognised as one of the world’s climate change hotspots. Average temperatures are rising around 20% faster than the global average, while heatwaves are becoming more frequent, more intense and longer-lasting (MedECC, 2020).
For countries like Greece, this carries particular significance.
Wetlands that provide essential resting places for millions of migratory birds face increasing pressure from reduced rainfall and higher evaporation. Mountain ecosystems experience shorter periods of snow cover, altering water availability downstream. Marine heatwaves affect coastal habitats, including the remarkable Posidonia seagrass meadows that act as important carbon sinks while providing nursery grounds for fish and countless marine organisms (Marbà & Duarte, 2010).
Climate change rarely acts alone. Habitat fragmentation, pollution, invasive species and unsustainable land use, all place additional stress on ecosystems. Together, these pressures make it increasingly difficult for wildlife to adapt (IPCC, 2023).
Our actions matter. Nature is remarkably resilient when we give it the chance. Wetlands recover. Forests regenerate. Seagrass meadows continue storing carbon for centuries when left undisturbed. Conservation works—and every choice we make helps decide which future becomes possible.
Slowing down changes the way we see the world
Over the past few years, something interesting has happened.
More people have started birdwatching. More families are choosing nature reserves, over crowded attractions. Hiking trails, wildlife photography and outdoor activities have become increasingly popular, especially among younger generations looking for meaningful experiences away from constant notifications and busy schedules.
Research increasingly shows that spending time in nature benefits both physical and mental wellbeing. Even hearing birdsong has been associated with improved mood and reduced symptoms of anxiety (Hammoud et al., 2022). Time outdoors encourages us to pay attention again. To notice the dragonfly hovering above a pond. The orchids hidden among the grasses. The bee-eaters calling overhead after their long journey from Africa.
When we begin noticing these small details, they stop being anonymous parts of the landscape. They become something we care about.
And people are far more likely to protect what they have come to know.
Can tourism become part of the solution?
Tourism is often discussed in terms of its environmental footprint. That conversation is important. But it is only half the story.
Tourism also has enormous potential to support conservation when it is designed thoughtfully. Responsible tourism is not about ticking a sustainability box or asking travellers to sacrifice comfort. It is about making choices that benefit both visitors and the places they explore.
Choosing local guides supports knowledge and livelihoods rooted in the landscape. Staying in locally owned accommodation keeps income within communities. Travelling in small groups reduces disturbance to wildlife while creating more meaningful experiences. Visiting protected areas responsibly helps demonstrate that healthy ecosystems have social, cultural and economic value.
Increasingly, the conversation is moving beyond sustainable tourism towards regenerative tourism. The idea is simple. Rather than aiming to minimise harm, regenerative tourism asks how travel can actively contribute to healthier ecosystems and stronger communities. It encourages restoration rather than extraction, participation rather than consumption.
It is a hopeful way of thinking about travel. Not as something separate from conservation, but as one of the many tools that can help support it.
Every choice becomes part of a bigger picture
Climate change is one of the defining environmental challenges of our generation. And while we shout against air traffic, which is no small footprint, no single journey, holiday or individual decision will solve it.
But every meaningful change begins somewhere.
It begins with understanding why a wetland matters beyond the birds it holds. Why an old forest is more than a beautiful backdrop. Why healthy ecosystems quietly protect us every day by storing carbon, regulating water, cooling landscapes and supporting the extraordinary diversity of life on which we all depend.
Perhaps protecting nature does not always begin with grand gestures. Sometimes it begins with slowing down long enough to notice what is already there.
The more we understand nature, the more likely we are to protect it.
And perhaps that is where responsible travel truly begins; not with the destination, but with the way we choose to experience it.
Perhaps the greatest privilege of travelling through nature is realising that we are never separate from it.
