Can you name one underwater forest? If not, you have a good excuse — most of them don't have names yet! Humans are just beginning to grasp the scale and impact of the ocean’s giant-kelp and seaweed forests. We now know they surround about one-fourth of Earth’s coastlines.
In May, scientists stated that the global biome of ocean forests rivals the Amazon rainforest in both total size and net primary production (NPP). NPP helps the Earth's carbon cycle.
More research is needed to learn how much carbon seaweed actually holds, though. These studies will show how the plant can help reduce climate change. But even as the need to study them grows, large expanses of ocean forest have recently disappeared due to climate change. Scientists hope that as sea ice melts and water temperatures rise, some Arctic ocean forests will expand.
Earth’s two currently stable underwater forests do have names. The Great African Seaforest is off of southern Africa, and Australia has the Great Southern Reef.
There are many more ocean forests all over the world. Some include brown kelp (100 feet tall). Others have sea bamboo (50 feet tall). Both of these plants have balloon-like structures that let them create floating canopies. Other ocean forests are home to golden kelp that carpet the seafloor.

This short video is an overview of key features of a rainforest habitat, covering the animals and environmental conditions found there throughout the year.
Deforestation and Climate Change (Water Cycle, Deforestation, and Climate Change #3)
In this lesson, students learn how climate change and deforestation are linked to the water cycle.
This inspiring video is about three young kids that work together to get their town and school to adopt solar panels and protect an area of forest near their homes.
