Assignment ENV 107 Topic: Submitted to Professor Dr. S.M. Atiqul Islam Submitted by Name: ID: Section: Date: Biodiversity: Biological diversity‚ or biodiversity‚ refers to the variety of life on Earth. As defined by the United Nations Convention on Biological Diversity‚ it includes diversity of ecosystems‚ species and genes‚ and the ecological processes that support them. Natural diversity in ecosystems provides essential economic benefits and services

earth’s orbital change‚ the slight lean of the earth’s axis‚ and the natural change in atmospheric composition. Although‚ since the industrial revolution in the late 1800’s‚ the rate in which our atmosphere warms has risen exponentially. There are dozens of effects that follow the new record high’s in atmosphere temperature; melting of the polar ice caps‚ rising ocean temperatures‚ an increased number of forest fires‚ and

excites or heats the ionized particles. HAARP was designed to probe 50k patches of the atmosphere with high frequency radio waves. The atmosphere is made up of three layers. The troposphere is from sea level to 16 km above the surface. The stratosphere includes the ozone layer‚ is from 16 km to 48 km. The ionosphere is 48 km to over 50‚000 km. It is electrically charged and surrounds the Earth’s upper atmosphere. The ionosphere is prone to catalytic reactions. This means if even a small part of

natural and man-made gas in the atmosphere which does not block sunlight but trap heat to keep the temperature on Earth suitable for life. Imagine a greenhouse that is made of glass that supports plants growth. Visible sunlight can go through the glass but the heat in which it contains can’t go back through the glass‚ thus a greenhouse keeps plants warm allowing them to live and grow happily. The same process with gas replacing the glass exists naturally in the atmosphere; this is how earth keeps herself

is now teaching conflict resolution at the American University School of International Service and gives workshops throughout the world. Dr. Weeks basically tears conflict resolution into eight steps. The first step is to create an effective atmosphere. The second step is to clarify perceptions. Third is focus on individual and shared needs. Fourth is build shared positive power. Fifth is look to the future‚ then learn from the past. Sixth is generate options. Seventh is develop "Doables

this cause but individually they contribute a small amount but are a huge factor as a whole. One of the main problems about the climate change is global warming. What is global warming? It is the increase in the mean temperature of the Earth’s atmosphere. It is said that the temperature has been rising by 0.5° every year and the highest temperature recorded was 47.6° in Faya‚ Chad in 22nd June 2010. This causes the sea levels to rise due to the snow melting. It is said that the sea levels will

Earth is changing Introduction We often think of the Earth as a stable and safe place to live. The landscape we see seems timeless and impossible to influence. At the same time‚ we know there are a lot of forces that affect our planet and change it. Some changes are quick‚ such as when earthquakes and volcanic eruptions break the ground or covering it with lava. Other changes may take millions of years‚ such as wind or the abrasive forces of water. The hunt for food‚ searching for land to cultivate

how these features interrelate. * The BPE is then the interactions‚ which occur between the Atmosphere‚ Lithosphere‚ Biosphere and Hydrosphere. ATMOSPHERE * Atmosphere‚ mixture of gases surrounding any celestial object that has a gravitational field strong enough to prevent the gases from escaping; especially the gaseous envelope of the earth. The principal constituents of the atmosphere of the earth are nitrogen (78 percent) and oxygen (21 percent). The atmospheric gases in the remaining

surface temperature. It is due mostly to the release of greenhouse gases (GHGs) into the atmosphere by human-fuelled activities such as increased fossil fuel consumption leading to the release of carbon dioxide (CO2)‚ the increasing use of automobiles‚ the use of nitrogen based fertilizers‚ and rearing and breeding large methane-belching cattle. He also said that greenhouse gases occur naturally within the atmosphere at levels that are not detrimental to the environment. According to Shah (2013)‚ many

will be the greatest environmental challenge in the 21st century.” So what is The global warming? why did Albert Gore states like this? And do we have a solution about this problem? Global warming is a rising average temperature of Earth’s atmosphere and ocean in long term. Global warming is already known as the greenhouse gases‚ which are emitted by a human activity‚ such as urbanization and industrialization. Moreover‚ August 03‚ 2009 Sky News announce that a warmer sun could increase global
