Turning the Tide: 5 Expert Insights on Crucial Changes to Save Our Planet from the Climate Abyss

If we know we need to act on climate change, why are we still hesitating? This question lies at the heart of a recent UN report that explores the barriers to real progress.

The 2025 report from the United Nations University Institute for Environment and Human Security (UNU-EHS) argues that our current systems are failing us. The authors highlight that many so-called solutions to environmental crises, like climate change and pollution, are merely quick fixes. They might even slow down real change. Professor Shen Xiaomeng, the director of UNU-EHS, points out, “Society is at a crossroads. Despite scientific warnings and solutions, meaningful actions are lacking.”

As climate change impacts worsen, emissions from fossil fuels keep rising to alarming levels, and species are disappearing faster than ever. A staggering two billion tons of household waste is produced every year globally—enough to wrap around the Earth with shipping containers 25 times. This is clearly unsustainable. Projections suggest that household waste could double by 2050 if we don’t change our habits.

Prof. Xiaomeng poses an uncomfortable question: “Why do we continue heading toward danger, even when we know the risks?”

To tackle this dilemma, the report offers the theory of deep change (ToDC), which looks at the root causes of our problems. It suggests focusing not just on symptoms, but on the core systems and beliefs that allow those issues to persist.

Consider a river choked with plastic. While we might blame waste management failures, this theory points to our production patterns and reliance on single-use plastics. The approach is about digging deeper, finding the behaviors and beliefs that drive these habits.

To effectively combat climate change, the UN report identifies five key areas for deep systemic change:

1. Rethink Waste: We need to embrace a circular economy. By prioritizing durability and reuse, we can drastically reduce waste output. Japan’s Kamikatsu town exemplifies this, boasting a recycling rate four times the national average through innovative strategies.

2. Realign with Nature: Our history of exploiting the environment has led to severe consequences like deforestation. However, restoring ecosystems can reverse damage. The Kissimmee River in Florida, once devastated by human intervention, is now flourishing due to recent restoration efforts.

3. Reconsider Responsibility: With 8.2 billion people sharing the Earth, the wealth and impact of climate change are not evenly distributed. The wealthiest nations often contribute disproportionately to emissions, which places a heavier burden on poorer populations. Sustainable practices must include social justice to make a genuine impact.

4. Reimagine the Future: Short-term thinking can be harmful. Nuclear energy, while a cleaner alternative to fossil fuels, leaves behind hazardous waste that remains a risk for millennia. In contrast, initiatives like the Svalbard Global Seed Vault aim to protect biodiversity for future generations.

5. Redefine Value: Economic growth alone isn’t enough. Bhutan’s Gross National Happiness Index, which prioritizes ecological balance over GDP, showcases the benefits of this perspective. In some countries, “green prescriptions” from doctors encourage spending time in nature, highlighting the broader values nature offers.

Research from the World Resources Institute supports these concepts by stating that focusing solely on individual actions might miss the bigger picture, achieving only a fraction of the required emissions reductions.

It’s time to pursue a path of deep change, recognizing that our current trajectory can lead to dire consequences. The challenges are significant, but with a shift in mindset and actions, we can work together for a healthier planet.
