Startup looks to seaweed to cut cows’ impact on climate

A Hawai‘i-based startup company is working to tackle climate change with tiny but mighty seaweed.

By feeding cows, sheep and other farm animals a natural seaweed-based supplement grown sustainably in state, Symbrosia in Kailua-Kona hopes to improve digestion and reduce livestock methane emissions, which are responsible for 10 percent of total greenhouse gases. It’s now eyeing trials at ranches across the state this summer, including on Maui.

Hāna Ranch, alongside other small farms and ranches is partnering with Symbrosia.
