We predict population and tourist activity is indicative of the levels of pollution- the more popular and populated a region results in higher amounts of pollution in the area. Pollution along the beaches will be most dense during the rain season when garbage is swept down the streets and into the rivers. In Southern Bali, we predict pollution will start in the cities where the most human activity occurs. Water is the transporter of trash. Rivers, streams and water runoff during the tropical island's wet season brings pollution from the cities onto the beaches and into the ocean. Because of this, we foresee pollution to be concentrated at river basins in the coastal cities where rivers deposit accumulated waste due to the flow of water from cities of higher elevations and through densely populated cities. Where rivers meet the sea is where much of Bali's pollution will be located. Through examination of Bali's river basins and the population growth of Southern Bali over time, we hope to prove our theory that population and popular travel destinations are the primary locations of pollution production, with rivers acting as transporters of waste and river basins as the final deposit site of pollution. If our hypothesis is correct, it should follow that tourist hotspots with large populations of people and rivers traveling through highly populated cities are the source of waste on the beaches, and ultimately the ocean.
