Read 2 article which already given and write a short review or reflection about them - Essay Example It is necessary to understand how each action taken by the current generation bears a consequence on the environment and in turn, how the changes affect not only them but also the future generations. This aspect of caring for the present as well as future and acting accordingly only constitutes sustainable development. The article, What is Sustainable development? Goals, Indicators, Values and Practice written by Robert W. Kates, Thomas M. Parris, and Anthony A. Leiserowitz focuses on this aspect. This paper by reflecting on the concept of sustainable development, featured in the article, will discuss how environment is being destructed by human activities and how sustainable development approaches could avert or even minimize the destructions, and thereby protect humans themselves. According to the authors, environmental impacts are one among the four themes which has raised the collective concerns of sizable sections of the population all over the world. â€Å"In the last half of the twentieth century, four key themes emerged from the collective concerns and aspirations of the worlds peoples: peace, freedom, development, and environment.† (Kates, Parris and Leiserowitz 2005). With peace and freedom actualizing in majority of the parts of the world in the post World War and Cold war periods, only the themes of development and environment is raising collective concerns. Development is taking place due to heightened economic activity, but ironically this development is indirectly impacting the environment. That is, development is happening or visible because of the increase in industrialization as well as increase in other materialistic things like automobiles. Among the many steps that countries take for economic development, most of them lead to Greenho use gases emissions (GHG) or particularly carbon emissions, one of the major causes of environment destruction.

Light Photography - Assignment Example Diffusion scatters light making the source broader and softer. For example, when clouds drift in front of the sun, shadows get less distinct. For the shadows to disappear, just add fog. Thirdly, bouncing light acts as diffusion. By aiming a narrow source of light at a broad matte surface such as wall and ceiling, it will not only reflect the light but will also diffuse it by scattering it over a wider area. The further the light source, the more it falls off meaning it gets dimmer on your subject. If light is moved twice as far from the subject you end up with only one quarter of it on the subject. Light fall-off can be used for varying the relationship between the light on your subject and your background. If a light source is placed close to the subject, the fall-off from the subject to the background will be more pronounced. When light is moved further from the subject, the background will be relatively brighter. Generally, I have learnt a lot from the light photography assignment. Light lessens shadows, the closer the source of light the closer the light, diffusion scatters light, and that bouncing light acts as diffusion. The further the light source, the more it falls off, Light falloff can be used to vary relationship and Front lighting deemphasizes
