This year marks twenty years since the release of Al Gore’s landmark documentary, An Inconvenient Truth. His 100-minute monologue helped catapult global warming to the centre of the political discourse, brought bring climate change into mainstream public discussion around the world and into our living rooms.

Whether one agreed with all of its conclusions or not, it succeeded in encouraging people to think more deeply about humanity’s relationship with the environment and the legacy we leave for future generations. Twenty years later, climate change is no longer a future concern discussed largely by scientists and policymakers. New Zealanders have experienced severe storms, flooding, droughts and wildfires. At the same time, we continue to face the loss of biodiversity, pressure on freshwater ecosystems and growing challenges in balancing development with the protection of the natural environment.

Looking back, however, what strikes me most is not whether every prediction proved correct. Rather, it is the lesson that meaningful environmental progress has rarely come from dramatic breakthroughs. More often, it is the result of countless small decisions made by ordinary people over long periods of time.

Many of the forests, reserves and natural areas we enjoy today exist because previous generations chose to protect them. They did not know exactly what the future would bring, but they understood that some places were worth looking after and some decisions were worth making for the benefit of people they would never meet.

We continue to benefit from those choices.

Whether it is walking beside Te Awa Kairangi, hearing tūī in regenerating bush, enjoying the forests of the Akatarawas and Tararuas, or spending time in one of the many reserves and natural areas around Upper Hutt, our connection to nature is often built through places close to home. Those experiences do not exist by accident. They are the legacy of decisions made by communities, volunteers, landowners and public agencies over many decades.

Looking back over the twenty years since An Inconvenient Truth was released, it is difficult to avoid the conclusion that we have known about many of these challenges for a long time. While governments around the world, including our own, have made varying degrees of progress, many of the environmental pressures facing future generations continue to grow. That reality makes individual and collective action more important, not less. Waiting for perfect policies or perfect leadership has rarely been a successful conservation strategy.

That is why I have never been entirely convinced by the argument that individual actions do not matter.

Most environmental gains begin with people deciding to do something. A landowner fences a stream. A volunteer joins a planting day. Someone sets a predator trap in their backyard. A family chooses to plant native trees rather than exotic species. A resident makes a submission on a proposal affecting a valued natural area. A community group commits to restoring a wetland, monitoring a waterway or protecting local wildlife.

None of these actions is transformative on its own.

What matters is when they are repeated, multiplied and sustained over time.

The return of native birds to many parts of the Wellington region, including Upper Hutt, did not happen because of one trap. Stream restoration did not occur because of one planting day. Ecological recovery does not happen because of one project or one organisation. It happens because thousands of people make small contributions that, together, become something much larger.

The same principle applies to climate change.

No individual can solve climate change. But individuals influence the communities, organisations and governments of which they are a part. Choices about how we travel, how we use energy, what we plant, what we consume and what we choose to support all contribute to larger patterns of behaviour. Collective action is simply individual action viewed at a different scale.

Perhaps the most important reason for acting, however, is not what we achieve today but what we leave behind.

Many environmental improvements take decades to become apparent. A native tree planted today may not reach maturity during our lifetime. A restored wetland may take years to recover its ecological character. Species that have disappeared from an area may take generations to return.

Yet previous generations made those investments on our behalf.

We enjoy the benefits of forests they planted, reserves they protected and decisions they made to safeguard natural places for the future. We have inherited those benefits, just as future generations will inherit the consequences of the choices we make today.

That places a responsibility on all of us.

Future generations will either inherit landscapes that are richer, healthier and more resilient, or they will inherit the cost of our failure to act. Every native tree planted, every stream restored, every wetland protected, every predator trapped and every effort to reduce environmental pressures is an investment in a future that others will experience long after we are gone.

Progress rarely arrives in a single dramatic moment. More often it is the cumulative result of countless small actions taken by ordinary people over long periods of time.

The natural places we value today are living reminders of that truth.

Our task is not to save the world single-handedly. It is simply to leave it better than we found it.
