The Ripple Effects of Our Impact

Research & Education

Our Objectives

Gather scientific data to advance marine research on microplastics and guide collective action.

Develop and deploy open-source curricula to teach high school students marine science and coding.

2020 Expedition Impact

Gathered data for airborne pelagic microplastic research with our partners at Scripps Institution of Oceanography.

What inspires the United World Challenge?

Every second breath we take comes from the ocean.

The oceans are our planet’s life support system. In addition to providing immeasurable cultural and natural value, the ocean provides critical services that keep us all alive.

The ocean:

Healthy oceans are fundamental to a prosperous and safe world, but the flood of plastic into waters worldwide is threatening our oceans and our own future. If we don’t act now, there will be more plastic than fish in our oceans by 2048. 
The United World Challenge is here to help by raising funds and action to invest in the most promising solutions to ocean plastic: creating low-cost river barriers in urban, developing regions, that catch plastic before it flows out to sea. 

Healthy oceans are fundamental to a prosperous and safe future.

We depend on the oceans for our very survival and they’re threatened now more than ever before. To ensure our future, it’s time we do something to protect the oceans.

It’s not too late to save the oceans, but time is running short. We need to act now – and the United World Challenge is here to help.

Interested in exploring sponsorship for future expeditions?

Sponsorship is more than just a good story. It’s about pursuing a vision greater than the sum of the parts. It’s about making impact neither partner could achieve alone.

In short, it’s about crossing oceans together.
