Introduction

  • In this module you will learn about the different approaches to environmental ethics. A table will summarize and classify the different approaches that have dominated the discussion for the last thirty years. These include extensionism, environmental virtue ethics, ecocentrism, biocentrism, and the land ethic.
  • Another table will help you to analyze problems in terms of the priority of basic over non-basic interests and human versus non-human interests. This will help break the habits we have of automically favoring human over non-human interests when making environmental decisions.
  • Byron Norton provides a Pragmatic approach to the environment that makes use of his considerable experience inside the Environmental Protection Agency. You will use a framework here that summarizes the different principles/values that he uses to define "sustainability."
  • Forming the background of environmental decision-making are basic concepts and procedures outlines in the discipline of ecology. This module will provide some basic definitions of ecological concepts like ecosystems. It will also outline some of the intellectual history of environmentalism by sketching different approaches to ecology as set forth by historical figures like Clements, Gleason, and Tansley.
  • Finally, an exercise section will help you integrate and practice these frameworks and concepts in the cases discussed above. When you finish this module, you will have a fuller, richer standpoint from which to make environmental decisions in the occupational and professional contexts.

    Environmental concepts

  • Ecosystems : "Ecosystems--forests, wetlands, lakes, grasslands, deserts--are areas in which a variety of living organisms interacting in mutually beneficial ways with their living and nonliving environments."(Des Jardins, 166)
  • Ecosystems : "Ecosystems are self-organizing systems that unfold on many scales and at many speeds; indeed, ecosystems exist on all scales from microhabitat to eco-region, so it is apparently irrelevant to ecological risks to identify at-risk individuls and count risks to them. (Norton, 9)
  • Characteristics of Ecosystems : (1) Boundaries serve to separate and distinguish ecosystems. These boundaries are porous, and ecosystems interact with one another. (2)Niches provide organisms within ecosystems with roles and associated activities. These niches organize organisms and their activities. Then the niches, themselves, are coordinated and interact within the overall ecosystem. (3) Succession characterizes the tendency of ecosystems toward internal and external dynamic integrity. Internally, the activities of organisms within a niche are coordinated with one another, and theses niches, themselves, interact according to stable patterns. In the past ecosystems evolved by passing through a succession of intermediate states toward a climactic stage characterized by internal and external equilibrium. This climax phase represents the ecosystem in its most mature phase.
  • Evolution : Charles Darwin "discovered" the theory of evolution and set forth its basic elements in his monumental work, "The Origin of Species." (1) The main thesis of evolution is that species, themselves, change, evolving in response to changes in the surrounding environment. (2) The main principle guiding the evolution of species is natural selection. Randomly produced variations embodied in the individuals that populate a species are, for the most part, not that important to survival. But occasionally a variation gives an individual a survival advantage that is perpetuated through this individual's increased ability to pass on these characteristics through reproduction. In this way, the surrounding environment filters out most random variations in individuals, allowing only those that provide a competitive advantage to be passed on. Over time, this leads to changes in the species itself. (3) Darwinism is important to environmental ethics because it provides a broader framework in which to understand the impact of human activities on the surrounding natural environment. Darwinism conveys both how dynamic the natural environment is and also how susceptible it is to the impact of human activities.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

or infinite solutions?
Kim
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world

how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
can nanotechnology change the direction of the face of the world
Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
