Plastic is one of the largest offenders when it comes to the pollution of the ocean. Everything from straws to take out containers are made of plastic and many of these products are designed to be single use. If single use plastic products are not properly disposed of, they could end up in the ocean due to litter or weather. Scientists estimate that in 2010 alone, 8 million metric tons of plastic found their way into the ocean. This problem is not getting any better as time goes on either. Unfortunately, plastic does not decompose, causing it to stay in the ocean indefinitely. This plastic waste will eventually break down into smaller pieces called microplastics; pieces of plastic less than five millimeters in length. Plastic fibers from fishing nets or synthetic clothing are able to absorb things like pesticides, dyes, and flame retardant. These chemicals will later be released into the ocean and have the potential to harm marine life.
ROV’s are able to give scientists a unique perspective on ocean pollution. In addition, they are able to assist in the cleanup of plastic and other ocean pollution. They serve as a cost effective research tool with the ability to complete tasks human divers would be incapable of. ROV’s also reduce the risk of divers being injured during operations.
