• In this society generally men hunt and women gather, they follow the egalitarianism
• The comparison of hunting with gathering permitted to evaluate the nutritional consequences for the people belong to foraging societies
• Generally, foragers had necessitated to meet their caloric needs through stable supplies of food, which included both qualitatively and quantitatively, hence to avoid malnutrition or starvation
• Hunting and gathering generally provides the forgers almost with the same amount of proteins, although they collect large quantities of edible plants to equal the outcome of proteins supplied with the relatively small pieces of meat

EPA has been able to formulate three most important environment laws in the country:
I) The Clean Air Act (CAA): CAA regulates air emissions from stationary and mobile sources. Among other things, this law authorizes EPA to establish National Ambient Air Quality Standards (NAAQS) to protect public health and public welfare and to regulate emissions of hazardous air pollutants.
II) The Clean Water Act (CWA): The Clean Water Act (CWA) regulates discharge of pollutants into the waters of the United States and regulating quality standards for surface waters. The basis of the CWA was enacted in 1948 and was called the Federal Water Pollution Control Act, but the Act was significantly reorganized and expanded in 1972.
III) Atomic Energy Act (AEA)
IV) Endangered Species Act (ESA)
V) Energy Policy Act
VI) Federal Food, Drug and Cosmetic Act (FFDCA) and many more.
According to the EPA website, the effectiveness of EPA has benefitted every life of an American. It claims of improving to the main three areas:
I) Cleaning up Environments: Clean and safe environment is an important factor in protecting health and prosperity of human. EPA believes in beautifying and protecting communities by ensuring an environment to its citizens where they can live, play, learn and work. Over the years, EPA has worked to clean up polluted and contaminated sites. EPA also has restored many abandoned areas to be used for parks, businesses and open space. Few of the efforts taken are:
a) Recycling: Recycling 10% of trash in 1980 to more than 33% in 2008 i.e., 83 million tons of trash.
b) Cleaning up communities: Cleaned more than 67% of the contaminated Superfund sites nationwide into bustling business centers and neighborhoods. Employment to more than 3,300 Americans with hourly wage of $14.26
II) Cleaning the air quality: Since the Clean Air Act came into effect it has made Americans healthier as 60% of dangerous pollutants have been reduced. Today, cars are 98% cleaner than in 1970s in terms of smog pollutants. An average American breathes 11,000 liters of air every day. This is the reason behind air quality being so important. In 1990 alone the Clean Air Act prevented:
• 205,000 premature deaths
• 672,000 cases of chronic bronchitis
• 21,000 cases of heart disease
• 843,000 asthma attacks
• 189,000 cardiovascular hospitalizations
• 10.4 million lost I.Q. points in children from lead reductions
• 18 million child respiratory illnesses
The progress has continued since 1990. EPA analysis shows that in 2010, Clean Air prevented more than 160,000 premature deaths.
III) Protecting America’s Water: Average American use 100 gallons of water every day. Water holds a great importance to the environment, economy, culture and history of communities across the country. Forty years ago the Cuyahoga River in Ohio was so filled with oily waste that it actually caught fire. Today, the EPA is protecting the water resources but every American has a role...
