The ocean absorbs 90% of the heat caused by human-driven climate change. Warming oceans are a huge problem for coral reefs as they require temperatures to stay within the range of 79-84F (26.1-28.8C) to remain healthy, grow, and reproduce. Current predictions estimate that 99% of coral could succumb to marine heatwaves by the 2030s if global temperatures continue to rise at the current rate.

This would have dramatic consequences not just for corals, but for the wider reef ecosystem. Although coral reefs only occupy 0.1% of the seafloor, 25% of all named marine species live in reef systems and an estimated one billion people benefit directly or indirectly from coral reefs. Coral ecosystems face a host of threats ranging from increasing ocean acidification to a rise in coral diseases but the steady and alarming increase in ocean surface temperatures poses the most ubiquitous and ominous problem.

Coral restoration typically involves transplanting nursery-grown coral onto the damaged reef by hand using individual divers, a very time consuming and arduous process that can be expensive and hard to do on a large scale. Foster decided that a new approach was needed to scale up coral planting, incorporating lessons from her family’s manufacturing business, such as automation and mass production.
