United States Environmental Protection Agency

The United States Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the U.S. federal government which was created for the purpose of protecting human health and the environment by writing and enforcing regulations based on laws passed by Congress. The EPA was proposed by President Richard Nixon and began operation on December 2, 1970, after Nixon signed an executive order. The order establishing the EPA was ratified by committee hearings in the House and Senate. The agency is led by its Administrator, who is appointed by the president and approved by Congress. The current administrator is Gina McCarthy. The EPA is not a Cabinet department, but the administrator is normally given cabinet rank.

The EPA has its headquarters in Washington, D.C., regional offices for each of the agency's ten regions, and 27 laboratories. The agency conducts environmental assessment, research, and education. It has the responsibility of maintaining and enforcing national standards under a variety of environmental laws, in consultation with state, tribal, and local governments. It delegates some permitting, monitoring, and enforcement responsibility to U.S. states and the federally recognized tribes. EPA enforcement powers include fines, sanctions, and other measures. The agency also works with industries and all levels of government in a wide variety of voluntary pollution prevention programs and energy conservation efforts.

The Last of the Masters

The Last of the Masters (also known as Protection Agency) is a science fiction novelette by Philip K. Dick. The original manuscript of the story was received by the Scott Meredith Literary Agency on July 15, 1953, and the story was published by the Hanro Corporation in the final issue of Orbit Science Fiction in 1954. It has since been reprinted in several Philip K. Dick story collections, beginning with The Golden Man in 1980.

"The Last of the Masters" depicts a society 200 years after a global anarchist revolution has toppled the national governments of the world (the exact year is unstated). Civilization has stagnated due to the loss of scientific knowledge and industry during the now-legendary revolt. Elsewhere, the last state, governing a highly centralized and efficient society, conceals itself from the Anarchist League, a global militia preventing the recreation of any government. When three agents of the League are sent to investigate rumors of the microstate's existence, the government arranges for them to be killed, leading to the death of one and the capture of another. Tensions rapidly escalate after the agents of the state realize that the third has escaped. Assuming he will report the state's existence, the government mobilizes for total war. In actuality, the surviving anarchist elects to attempt his comrades' rescue and assassinate the head of state: the last surviving "government robot".

Environmental protection

Environmental protection is a practice of protecting the natural environment on individual, organizational or governmental levels, for the benefit of both the natural environment and humans. Due to the pressures of population and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, activity of environmental movements has created awareness of the various environmental issues. There is no agreement on the extent of the environmental impact of human activity, and protection measures are occasionally criticized.

Academic institutions now offer courses, such as environmental studies, environmental management and environmental engineering, that teach the history and methods of environment protection. Protection of the environment is needed due to various human activities.ref. Waste production, air pollution, and loss of biodiversity (resulting from the introduction of invasive species and species extinction) are some of the issues related to environmental protection. Environmental protection is influenced by three interwoven factors: environmental legislation, ethics and education. Each of these factors plays its part in influencing national-level environmental decisions and personal-level environmental values and behaviors. For environmental protection to become a reality, it is important for societies to develop each of these areas that, together, will inform and drive environmental decisions.

Climate change

Climate change is a change in the statistical distribution of weather patterns when that change lasts for an extended period of time (i.e., decades to millions of years). Climate change may refer to a change in average weather conditions, or in the time variation of weather around longer-term average conditions (i.e., more or fewer extreme weather events). Climate change is caused by factors such as biotic processes, variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions. Certain human activities have also been identified as significant causes of recent climate change, often referred to as "global warming".

Scientists actively work to understand past and future climate by using observations and theoretical models. A climate record—extending deep into the Earth's past—has been assembled, and continues to be built up, based on geological evidence from borehole temperature profiles, cores removed from deep accumulations of ice, floral and faunal records, glacial and periglacial processes, stable-isotope and other analyses of sediment layers, and records of past sea levels. More recent data are provided by the instrumental record. General circulation models, based on the physical sciences, are often used in theoretical approaches to match past climate data, make future projections, and link causes and effects in climate change.

Special agent

In the United States, Special Agent is usually the title of a detective or investigator for a state, country, municipal, federal or tribal government who primarily serve in investigatory roles. Uniquely, many railroad police departments in the U.S. utilize "Special Agent" as either a rank or title, even if the special agent's role is not primarily investigatory in nature. Within the United States' federal law enforcement system there are dozens of federal agencies that employ federal law enforcement officers, each with different criteria pertaining to the use of the titles "Special Agent" versus "Agent." In general, some, but not all, agents are federal law enforcement officers, and hold either arrest authority or the right to conduct minor criminal/non-criminal investigations. However, there are some agencies where an agent may have both arrest and minor criminal/non-criminal investigatory authority, but still have no authority to conduct major criminal investigations. On the other hand, nearly all special agents are federal law enforcement officers, are distinctly empowered to conduct both major and minor criminal investigations, and hold arrest authority. Most special agents are authorized to carry firearms both on and off-duty, whereas only some agents are authorized to do so.
