The Delta’s ecosystems store billions of tonnes of carbon in a vast peatland and boreal forest ecosystem, acting as a critical natural storehouse for carbon and a buffer against climate change.
Why is a river delta important?

The word “delta” comes from the Greek letter, which looks like a triangle.

How do deltas affect the environment?
Urbanizing deltas can not only be adversely impacted by increased flooding due in part to sea level rise but also can contribute to causes of climate-driven sea level rise by being centers of oil and gas production. The world’s largest centers of oil and gas processing are situated in deltas.
How are deltas useful to wildlife?
Because it is located at the confluence of California’s two largest rivers, the Delta serves as a key migration corridor for many fish and wildlife species.
