Review Chapters 1-3

Chapter 1:
Chapter one called Environmental ethics, in this chapter they ask is environmentally profitable? They name two companies that seek profits through the promotion of environmental awareness which are the Rainforest Cafe and Outdoor World. The Rainforest Cafe is a resturant and gift shop, with a virtual jungle theme. Outdoor World is a retail dsports superstore selling anything related to fishing, camping, hunting, and other outdoor activites.
Industrial Ecology is the means by which humanity can deliberately amd rationally approach and maintain a desirable carrying capacity, given continued economic, cultural, and technologically evolution. some concerns throught global, and regional are: Global climate change, ozone depletion, loss of habitat andreduction of biodiversity, acid precipitation, chemical change in surface water, visibility, pesticides, groundwater pollution, photochemical smog, oil spills, and lastly hazardous waste sites.

Chapter 2:
Geography of the Envionment, there are al different maps that show the world whether its a three dimensional models and depressions of regions on two dimensional surfaces and portray both manmade and natural features. this would include this such as mountains, valleys, lakes, rivers, plains, and vegetation-man's primary creations, such as major buildings, roads, boundaries, and conveyance lines can also be identified. many specific types of maps are actually a combination of a base map and a thematic map. Exapmles would include political maps: show cultural features like the outlines of countries, states, and cities. Physical maps: show natural features such as mountains, rivers, lakes, and shorelines. Road maps: shows major and minor highways, cities, and towns, often with campgrounds, parks, and other tourist features. Weather maps: shows weather conditions such as fronts, temperatures, rain, snow, and fog at a particular time, or range during a particular period. and lastly summary maps show the results of analyzing grouped data.
Carbon cycle: Carbon is found in large sums in oceans and sedimentary rocks. once carbon reaches water, it precipitates to form calcium carbonate. Corals and algae build up limestone reefs though this carbon precipitation process, creating suitable environments for their population and sources of carbon for further respiration. on land and in water, plants convert carbon dioxide into carbohydrates through photosynthesis. then the carbon is either liberated into the atmosphere, eaten by animals when plants die, or decompose into the soilfor further extraction by plants and useful resources.

Chapter 3:
Biodiversity: One of the most important habitats for species is the Tropical Rainforest. the importantance of this because they account for millions of species of flora, and half of all presently known animals and plant species. Arthropod diversity in the rainforest alone numbers approximately five to ten millions species. The men temperature is near twenty-six degrees celsius yea round, and this circumstance allows the forest to be in a constant state of maintaince.
Ecological diversity: A key way in preserving the wide diversity of animals is the ecological system. It aides with capturing energy, sustained food webs, and recyclinh materials within the system. There are many critical factors that plays a role in every living orgaism. some of these major factors are tempertures, moisture levels, nutrient supplies, soil and water, chemistry, and living space. Each organism has a different tolerance level inwhich the species can or can not survive. most species have evolve with coevolution, most species play a major role in their community among other species and oprganisms.
Endangered and Threatened Species: Over the millions of years many species have become extinct or endangered. The species we see today are only a mere fraction of what use to exsist. An example of this would be the Florida Panther. The panther has become endangered due to hunting, habitat loss, and being isolated to the wetlands of south florida.
