Why stop pollution?
Adopting pollution prevention practices and techniques often benefits industry by lowering a company's operational and environmental compliance costs. By preventing the generation of waste, pollution prevention can also reduce or eliminate long-term liabilities and clean-up costs. Furthermore, disposal costs are reduced when the volume of waste is decreased. This can also lead to a reduction in workplace exposures to hazardous materials which can affect workers' health and hence, their productivity. If less waste is produced, there will also be a diminished need for on-site storage space. Furthermore, by preventing pollution there will be a greater likelihood that a company will be in compliance with local, state, and federal compliance statutes. Finally, as community pillars, businesses shoulder an important responsibility for protecting the environment and natural resources for their own good as well as that of society.
How do we stop pollution?
One way is to track oil spills, so there will be a better chance at preventing it before it all hits the water. With a large coverage, day and night, and all weather capability, ERS SAR imagery has been proven to be a very effective tool for ocean oil spill monitoring. This paper discusses ocean oil pollution detection and mapping in the Southeast Asian waters by using ERS SAR data. Possible oil slicks are detected first from each image and a normalized average oil slick occurrence intensity is then computed after all the available multi-temporal scenes in an ERS frame have been studied. The scene in which most slicks have been detected in a frame is then selected for re-examination. All oil slicks detected on this image are then further classified into either high or low probability categories. A new normalized maximum oil slick occurrence intensity is computed for each of the total and high probability oil slicks. Spatial distribution maps of the average and worst oil pollution situation for the Southeast Asian waters are then derived.
