Climate Change and Human/Wildlife Health: Direct and Indirect Effects and The Greenhouse Effect By Emanuel Picon Climate change effects are activities that threaten human and animal health, such as habitat destruction and urbanization, and pollution. These human activities directly affect the ecosystem and indirectly affect human and animal health as well. Climate change can also be seen in physical and climate events, such as the El Niño and solar radiation that have large effects on the Earth’s climate and in humans and animals. A lot of evidence exists for climate bad effects on wildlife. Factors of concern, such as ecosystem composition and pathogen virulence, are said to be related to climate changes.
Amy LaCasse Environmental Studies Charles Kaminski 18 July 2011 Environmental Science- An Interdisciplinary Approach Environmental science is a broad and complex field concerned with the study of the natural environment and the effects on that environment of human activity and natural events. This branch of science deals with such issues as deforestation, soil erosion, air and water pollution, global warming, loss of fisheries, the fate of hazardous chemicals in the environment, management of the earth’s water resources, and the destruction of habitats on land and in the ocean. All of these environmental challenges are multidisciplinary in nature. Because these concerns are so far-reaching and many environmental problems are interconnected, environmental science encompasses a number of varied areas of science. In order to understand each environmental challenge well enough to develop viable solutions, scientists must have expertise in several disciplines of science.
How Cities Affect Climate Definition of climate change: |Main Entry: |climate change | |Part of Speech: |n | |Definition: |any long-term significant change in the weather patterns of an area | |Example: |Climate change can be natural or caused by changes people have made to the land or atmosphere. | As greenhouse gases build up, the earth’s climate is changing. Human activities are the cause of this. If this continues at this rate, droughts, floods and other types of extreme weather will become more constant and in turn could affect food supplies. There are many plants and animals that will not be able to adjust to these patterns and may become extinct.
In recent years there has been a growing awareness of the extent to which human activities, such as deforestation and fossil fuel burning, have directly or indirectly changed the biogeochemical and physical processes involved in determining the earth's climate. These changes in atmospheric processes can disturb a variety of ecosystem services that humans depend upon. Humans clearly disturb many, if not all biogeochemical cycles and in the process threaten many ecosystems. In recent years human activities have directly or indirectly affected the biogeochemical cycles that determine climatic conditions of earth. The following summary is how human activities have contributed to disruption of biogeochemical cycles (M Moses et al., 2010): Use of phosphorus fertilizers: Human influences on the phosphorus cycle come mainly from the introduction and use of commercial artificial fertilizers.
There are many environmental ethical issues being studied today. One of the major issues is global warming. Global warming is said to have many negative effects on the environment. Global warming has been studied for a while now. I will be covering the aspects, causes and effects of Global Warming.
Air pollution comes from a wide variety of sources * Vehicle or manufacturing exhaust * Forest fires, volcanic eruption, dry soil erosion * Building construction or demolition Many scientists believe that global warming is also related to increased air pollution. 2. Water Pollution Water pollution involves any contaminated water, whether from chemical, particulate or bacterial matter that degrades the water’s quality and purity. It can occur in oceans, rivers, lakes and underground reservoirs. Causes of water pollution include: * Increased sediment from soil erosion * Improper waste disposal and littering * Leaching of soil pollution into water supplies The effects of water pollution include decreasing the quantity of drinkable water available, lowering water supplies for crop irrigation and impacting fish and wildlife that require water of certain purity for survival.
The Vanishing Islands and Atolls The Link to Climate Change and Global Warming Ricardo Pail Sarcar University of Saint Joseph Abstract In this study, I have investigated the climatological effects of global warming and climate change in relation to the vanishing islands and atolls of the Pacific, Atlantic and Indian Oceans to determine the adverse effects of climate change to these islands. Secondary data was reviewed my personal computer using Internet search engines. To aid the search, a table of key terms was constructed and the sources located will be correlated with this. The information I have extracted from my research shows that the rising temperatures have been causing a very unstable climate globally which in turn causes severe weather conditions such as floods and tsunamis which have been wiping atolls off the oceans. The rising temperatures have caused ice to melt in the Arctic and the North Pole which have been increasing the volume of water in the sea, gradually rising up to the shores of the islands and atolls.
The 11th Hour shows us the consequences of irreversible global warming that have already begun to affect our life and environment. The film cites many recent climate change and natural disasters. Throughout the facts, we see that human life must depend on the natural environment. According to Thom Hartmann, “We are a part of nature. We can’t separate from nature.” As DiCaprio tells us we cannot survive without nature.
Since the temperatures have started to rise, the ice that they once lived on has melted and they are having a very difficult time surviving. People have increased the temperature of the Earth by contributing their pollution. Burning fossil fuels and forests has been the biggest issue amongst us all. Simple changes could help in simple ways but the fact is that since it is a global issue, the world has to be involved in order to make a difference. The United Nations has contributed in this way by holding meetings to discuss the climate changes throughout the world and what can be done to help.
In fact, issues of distributive justice in the context of climate change are overly deep-rooted and have far-reaching impacts not only for the current generations but future generations as well. Queries related to siting and management of storage sites which encompasses concerns associated with risks and uncertainties of the technology; consideration of risk perceptions of all stakeholders; autonomy (or monopoly) of actors over the development and implementation of the technology; sources of funding (cost burdens) for technology deployment; discrepancies between local hazards and global good nature of the technology (as it abates GHG emissions), etc. are some of the predominant moral contestations with respect to distributive justice within CCS. Thus, a fair allocation of benefits and burdens involves socio-techno-economic factors and calls for action by the local, national and international actors. Although most of these concerns are not specific to CCS only, but the complexity and political implications of these factors in the context of CCS is certainly much more intense and contentious as it firstly, pertains to climate change, and secondly, there are too many unknowns in the technology as of
