Third, program evaluation must be able to consider political and environmental context. It is in this particular characteristic that the authors aver the importance of stakeholders: the evaluator, the one to commission the evaluation; and other organizations or individuals that have significant stakes in the program. On the other hand, the results that evaluations aim for should be timely and meaningful especially to decision makers as this will determine the fate of the program. (Rossi et al.,:2004) Finally, program evaluation seeks to improve social conditions by informing social action. Findings from assessments should always serve as a basis for decisions for actions or non-actions towards the program.
Over one thousand otter carcasses were found and an estimated two thousand eight hundred died from the spill. As a direct result of the spill, roughly three hundred harbour seals died. The oil spill later on caused a collapse of the Pacific Herrings’ population because nearly half of their eggs laid in 1989 were exposed to the oil (Liszka 1-30). These deadly outcomes changed their environment
Aditionally, mining activties also affected water pollution by increasing the amount of toxic elements released into the environment. When coal and other minerals were extracted from underground, they emited several metal waste which was harmful for the water. It is evident that the Indutrial Revolution caused a lot of evnviromental problems for individuals. Without social protest it is doubtful politicians would have responded to the environmental crisis…in the late 1960’s and ealry 1970’s (Halbert, par. 1).
In fact the industries would dump their garbage right into Lake Erie itself or Lake Erie 's tributaries. Lake Erie also had pesticides, fertilizer and other agricultural runoff going into its waters. These pollutants caused Lake Erie 's water to have high phosphorus and nitrogen measures. High amounts of Phosphorus and Nitrogen can lead to an algae bloom. The algae led to low oxygen levels in the water.
AMD (Acid Mine Drainage) is created from sulfuric acid. It 's created when sulfuric acid makes contact with metals and other chemicals from the disposal site and then it creates AMD. Amd does many terrifying things to the environment like, it contaminates lakes, rivers, ponds, and other bodies of water. It also harms human health, fish, wildlife, and it also damages the entire ecosystem. Even the economy gets affected from sulfide mining.
Just because they are here means that it is of view to mankind. The considerations that lead to view the nature has intrinsic value are based on value. Firstly, the organism is good just because they have value. This is also true for species populations and communities of life. Ethically, man should have respect for the environment as it has inherent worth and value.
Each of these phenomenon’s has left families broken, nations ruined and history wrongly changed. Because environmental, weather- related disasters and war have claimed the lives of many people, these events have had the greatest impact in history Some environmental disasters include oil spills and explosions. The Exxon Valdez was a cargo ship, carrying 1,264,155 barrels of oil, which ran ashore Bligh Reef, in March 1989. Over 200 miles of land was enveloped in oil and stretched about 1,300 miles across the shore line. Not only were thousands of fish, sea otters and bird remains found but billions of dollars were consumed in the cleaning up process.
These include billions of tons of waste rock, very deep and wide open pits, high and long miles of dams, and the production of acid mine drainage, all of which can significantly affect wild salmon fishery. The pits can also become a breeding ground of mosquitoes that would cause illnesses to people living nearby. 2. Economic risks Pebble mining may open plenty of job opportunities, but it can also affect the other side of livelihood. A huge population of Alaska is heavily dependent on fishing, and the damage that pebble mining can cause to the fishing industry is likely to cripple a lot of people and communities.
Bacteria and metals spread through the floodwaters, and the storm destroyed acres of forestry while leaving the Gulf Coast highly polluted with crude oil. According to Gale, “An estimated 6.5 million gallons of crude oil, as well as fuel from cars, boats, gas stations, and households, was spilled… Floodwaters also tested positive for E. Coli bacteria and heavy metals… The coastal marshes, which act as a natural barrier and protect the coastline from tidal surge, were also destroyed” (Gale). The oil spill, which was considered to be one of the worst oil spills in the country’s history, significantly destroyed the biodiversity of the Gulf Coast: beaches, marine animals, and marshlands that protected the coast from storm surges as a natural barrier. The spill of tons of industrial waste and raw sewage in the floodwaters contributed to the existence of E. coli and heavy metals, which had heavy impact on the heath conditions of the residents of the area. The storm also damaged about 1.3 million acres (5,300 km²) of forestland, 14.6 million cords (52,900,000 m³) of paperwood, and 3.2 billion board feet (7,600,000 m³) of sawtimber in Mississippi.
Marine life habitats are getting destroyed, marine life is declining everyday, how and where the garbage is getting into the oceans, and the drinking water is becoming seriously unsafe to drink. Water Pollution is a huge environmental problem that has serious effects on marine habitats, animals, and water quality. BP1: The world's marine habitat has been getting worse because of how bad the pollution has gotten. “ Over 80% of marine pollution comes from land based activities “ (source 5 ). This quote explains how most of the water pollution is caused by human activity.
