*Seagrass is the base of important marine ecosystems, providing an environment which serves as a nursery for young fish, rich in nutrients and invertebrates for food, while at the same time providing a grazing site for other larger vegetarian marine life. Additional functions and dangers to Seagrass in both temperate and tropical climates are shown above.
*There are 60 different types of seagrass.
*Seagrass grows only in the Photic Zone (the area of the sea where light can penetrate) in coastal regions on every continent except Antarctica.
*Seagrass requires a soft or sandy substrate region in which to grow.
*Many organisms have evolved to live only in seagrass ecosystems.
*Seagrass levels worldwide have decreased by 30000 square kilometers in the past 20-30 years.
*A healthy seagrass ecosystem is vital to having a healthy fishing system.
*Seagrass can be directly killed by the over-input of elements such as phosphorous or nitrogen.
*Radiation has also been proven to have lasting effects on seagrass.
