A new report from the U.N. Environment Assembly highlights the urgent need for a united approach to tackle serious environmental issues. These include climate change, biodiversity loss, land degradation, and pollution, which put over a million species at risk of extinction. Nearly 300 scientists from 83 countries contributed to the findings.
Bob Watson, a lead author and former climate scientist, emphasizes that we cannot separate climate change from other environmental challenges. He warns that ignoring these interconnected issues could harm not only the planet but our economies and societal well-being. For example, pollution alone is linked to around 9 million deaths annually, according to the World Health Organization.
To truly address these challenges, experts suggest that all aspects of society—governments, industries, and individuals—must work together. They advocate for a circular economy that acknowledges the limits of natural resources. Watson asserts that achieving sustainability will require unprecedented change, and it must happen quickly.
The consequences of inaction could be dire. Greenhouse gas emissions hit an all-time high in 2024, with burning fossil fuels being the main culprit. If current trends continue, global temperatures could rise by 2.4 degrees Celsius by 2100, surpassing targets set in the Paris Agreement. This could lead to more severe weather events, like intense storms and droughts.
Climate change acts as a “threat multiplier,” worsening issues like land degradation and deforestation, according to Katharine Hayhoe, a climate scientist at Texas Tech University. She emphasizes that if we don’t tackle climate change, we won’t solve these other problems either. Scientists estimate that about 40% of the world’s land is degraded, emphasizing the urgency for action.
Funding for comprehensive solutions is essential. While the required investment is significant—around $8 trillion annually to achieve net-zero emissions by 2050—experts argue that this is far less than the costs of ignoring these issues. The report suggests that by 2070, benefits could exceed expenditures, leading to economic growth.
Michael Mann, another climate scientist, echoes the need for collective action, stating the stakes are too high to prioritize political convenience over the planet’s future. Despite this urgency, international cooperation remains faltering, especially with some leaders skeptical of climate change’s impact.
As negotiations on a treaty to manage plastic pollution recently ended without agreement, the future of global environmental efforts depends on countries willing to act decisively. Watson notes that while some nations will continue to push forward, others may lag behind, especially if influential countries like the U.S. do not lead by example.
Ultimately, Hayhoe emphasizes the importance of ensuring a thriving human society on Earth. “It’s not about saving the planet; it’s about preserving our future,” she says.
