Explosive population growth in American Samoa has led to rapid development. Most of the population of American Samoa resides on the island of Tutuila, however, merely 30% of the land areas has a slope of less than 30% and is therefore considerable habitable land.

As a result, the population density of the island is 2,800 people per square mile. Most of the land favorable for development lies adjacent to the coast. This density places a considerable and ever-increasing demand on American Samoa’s coastal areas.

Streams entering coastal waters carry large amounts of sediments and nutrients, stemming from the many homes and businesses located along them.

Below are ways we can reduce land-based sources of pollution and help protect American Samoa's coral reefs and other natural resources:

Protect and plant native vegetation

Install a rain garden

Identify and fix erosion issues

Promote vegetation buffers around waterbodies

Don’t be a litter bug

Wash your vehicle on grass or gravel, not on the street or hard driveway

Be mindful of what you put in storm drains, ditches, streams, and the ocean

Properly dispose of lawn and household chemicals

Find an AS-EPA Lube Cube at local gas stations for used motor oil

Collect rainwater with a rain barrel or cistern

Only use a small amount of pesticide or fertilizer, follow labels, and apply it well before it rains

Your gutters’ downspouts should empty into your yard, not the driveway or sidewalk

Compost kitchen and yard waste
