Question and answer
What are the historical patterns surrounding sustainable and unsustainable human interactions with the environment?
Unsustainable interaction between people and ecosystems has often been associated with human migrations. [ When people move to a new area where the ecosystem is different, they typically have little knowledge about the new ecosystem and lack appropriate social institutions and technology for sustainable interaction. This appears to have occurred when the first human inhabitants of North America
migrated there from Asia about 13,000 years ago. When these people arrived, North America had numerous species of large mammals similar to the impressive fauna in East Africa today. Most species of large mammals disappeared within a few centuries of the people arriving, probably due to overhunting. We do not know that the Native Americans were definitely responsible, but it appears likely. Many large animal species in Europe and Australia also disappeared soon after the first humans migrated to those continents. ]

How can risk assessment be used to determine health hazards and their effects on society?
Weegy: The Federal Government, in cooperation with the States, carefully regulates pesticides to ensure that they do not pose unreasonable risks to human health or the environment. [ As part of that effort, the Environmental Protection Agency (EPA) requires extensive test data from pesticide producers that demonstrate pesticide products can be used without posing harm to human health and the environment. EPA scientists and analysts carefully review these data to determine whether to register (license) a pesticide product or a use and whether specific restrictions are necessary. This fact sheet is a brief overview of EPA’s process for assessing potential risks to human health when evaluating pesticide products. Background There are more than 1055 active ingredients registered as pesticides, which are formulated into thousands of pesticide products that are available in the marketplace. EPA plays a critical role in evaluating these chemicals prior to registration, and in reevaluating older pesticides already on the market, to ensure that they can be used with a reasonable certainty of no harm. The process EPA uses for evaluating the health impacts of a pesticide is called risk assessment. EPA uses the National Research Council’s four-step process for human health risk assessment: Step One: Hazard Identification Step Two: Dose-Response Assessment Step Three: Exposure Assessment Step Four: Risk Characterization ] (More)

Where and how we live and work affects our health all the time. Evidence suggests that hazards in our environment contribute to human cancers, reproductive problems, birth defects, and even behavioral disorders among other diseases. (The word "Environment" here includes our diet and living habits as well as our surroundings.) Our bodies contain measurable amounts of industrial chemicals, pesticides, and other toxic wastes from the air, soil, food, and water. Chemicals in household products, biological hazards, and physical stresses at work and at home may also contribute to illness or injury.

What is the second law of thermodynamics?
Weegy: The second law of thermodynamics is an expression of the tendency that over time, differences in temperature, pressure, and chemical potential equilibrate in an isolated physical system. [ From the state of thermodynamic equilibrium, the law deduced the principle of the increase of entropy and explains the phenomenon of irreversibility in nature. The second law declares the impossibility of machines that generate usable energy from the abundant internal energy of nature by processes called perpetual motion of the second kind. ] (More)
