Should Carbon dioxide Be Regulated Along with other Major Air Pollutants?
The six common pollutants, sometimes called the criteria pol- lutants, are ozone, particulate matter, lead, nitrogen dioxide, carbon monoxide, and sulfur dioxide. These pollutants have a long history with the EPA, and major efforts have been made to reduce them in the lower atmosphere over the United States. This effort has been largely successful—all of them have been significantly reduced since 1990.
In 2009, the EPA suggested that we add carbon dioxide to this list. Two years earlier, the U.S. Supreme Court had or- dered the EPA to make a scientific review of carbon dioxide as an air pollutant that could possibly endanger public health and welfare. Following that review, the EPA announced that greenhouse gases pose a threat to public health and welfare. This proclamation makes it possible that greenhouse gases, especially carbon dioxide, will be regulated by the Clean Air Act, which regulates most other serious air pollutants.
The EPA’s conclusion that greenhouse gases harm or en- danger public health and welfare is based primarily on the role these gases play in climate change. The analysis states that the impacts include, but are not limited to, increased drought that will impact agricultural productivity; more intense rainfall, leading to a greater flood hazard; and increased frequency of heat waves that affect human health. The EPA’s proposal pro- gram to regulate carbon dioxide as an air pollutant has been upheld by court decisions
The next step in adding carbon dioxide and other green- house gasses, such as methane, to the list of pollutants regulated by the EPA was a series of public hearings and feedback from a variety of people and agencies. Some people oppose listing carbon dioxide as an air pollutant because, first of all, it is a nutrient and stimulates plant growth; and, second, it does not
directly affect human health in most cases (the exception being carbon dioxide emitted by volcanic eruption and other volcanic activity, which can be extremely toxic).
The EPA in late September of 2013 announced the initial steps to reduce carbon pollution under President Obama’s Cli- mate Action Plan. The objective will be standards for new coal burning power plants. Conversations are st ...

The great lakes have experienced anthropogenic effects over the last.pdfamolmobileshop
The great lakes have experienced anthropogenic effects over the last decades. a) Describe two
effects on the great lakes that have been observed in the last 50 years; b) Explain how these
effects were initiated, and c) Comment on how or if these effects can be mediated or resolved
Solution
The natural environment suffers from many harmful practises of humans and the system of the
Great Lakes is no exeption. Two effects on the great lakes which have been observed in the last
50 years are :
1. Mercury pollution
2. Pesticide pollution
These effects and causes are described below.
1.Mercury pollution - The Great Lakes are natural resource providing drinking
water,employment, food and transportation to more than 35 million people, including one-third
of the Canadian population and one-tenth of the U.S. population. It is the largest freshwater
system in the world and contains about 84 percent of North America’s fresh surface water. Any
type of pollution will effect a large amount of population and especially mercury pollution.
Causes : - Initial causes were mostly due to the discharge by the industrial units which used
merury. They directly drained into the lakes. But now these sources have been controlled.
Now the main source of mercury pollution is emission and deposition. The different industries
in the Great Lake basins which vause emissions are coal-fired power plants and eletri arc
furnaces.
After mercury is emitted to the atmosphere, it eventually returns to the Earth’s surface in a
process termed atmospheric deposition. Deposition is categorized as wet deposition (i.e.,
mercury deposited in precipitation), dry deposition (i.e., mercury deposited as gas and particles),
and litterfall (i.e., mercury that is incorporated into the needles and leaves of plants, which
eventually fall to the ground as the foliage is shed). Litterfall is considered a component of dry
deposition.
The harmful effects of mercury pollution result from the exposure of organisms including
humans to methylmercury, a highly toxic compound that biomagnifies in aquatic food webs to
concentrations that can reach levels several million times higher than those in water.
Mitigation or resolution - Few mitigation steps could be :-
a. Monitoring of mercury and research
b. Lower Regulatory Thresholds for Major Mercury Emission Sources
c. Require Best Available Control Technology for New and Modified Sources
d. Mandate Mercury Emissions Reporting
2. Pesticides :- Pesticides can contain a variety of toxic chemicals. These chemicals can benefit
our society and can also be very harmful too. Historically, pesticides have been extremely useful
to society. Pesticides can prevent harmful diseases and help kill pests from farmed crops
suffering. Pesticides have been known to causing harm to humans, animals, and the environment.
The toxic pollutants that are harming the Great Lakes are human-made organic chemicals, also
known as pesticides.
Causes : The primary reason for water pollution in .
Mitigation Strategies to Greenhouse Gas Emission Control: A Database for Emis...IJSRD
With the advancement of Industrial Revolution, the anthropogenic activities have brought about increase in the quantities of greenhouse gases (GHGs) into the atmosphere leading to various climatic changes. The climate change is mainly caused by production of GHG emissions in the atmosphere. As the major population of the world seems to agree with the concept of ‘human development’ including the ‘environment’ factor, the various attempts for sustainability is not found to be interesting or beneficial. Therefore, the main motto of the world is to improve the standard of living by attaining suitable measures. However, most of the population on earth still do not get ‘bare minimum’ for development; the humanity faces the challenge of the “Climate Changeâ€Â. Various efforts need to address climate change through mitigation of GHG emissions and building of adaptive capacities to deal with the severe impacts of climate change.

impactos del cambio climatico en ecosistemas costerosXin San
Anthropogenically induced global climate change has profound implications for marine
ecosystems and the economic and social systems that depend upon them. The
relationship between temperature and individual performance is reasonably well
understood, and much climate-related research has focused on potential shifts in
distribution and abundance driven directly by temperature. However, recent work has
revealed that both abiotic changes and biological responses in the ocean will be
substantially more complex. For example, changes in ocean chemistry may be more
important than changes in temperature for the performance and survival of many
organisms. Ocean circulation, which drives larval transport, will also change, with
important consequences for population dynamics. Furthermore, climatic impacts on one
or a few leverage species may result in sweeping community-level changes. Finally,
synergistic effects between climate and other anthropogenic variables, particularly fishing
pressure, will likely exacerbate climate-induced changes. Efforts to manage and conserve
living marine systems in the face of climate change will require improvements to the
existing predictive framework. Key directions for future research include identifying key
demographic transitions that influence population dynamics, predicting changes in the
community-level impacts of ecologically dominant species, incorporating populations
ability to evolve (adapt), and understanding the scales over which climate will change and
living systems will respond.
Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.
