Environmental health Effect and Air Pollution from cigarette smokers in Cross...IOSR Journals
This study is aimed at assessing the cause of air pollution and Environmental health effect on people living in Cross River State using cigarette smokers as a case study. Data was gathered through a well designed and articulated oral and written questionnaires, direct and first-hand observation of the environment, and comprehensive interview sessions were carried out with community Heads (Royal Authorities where possible), patients and youths. A total of one hundred and seventeen thousand (117,000) questionnaires were randomly distributed evenly to men of about 20-75years old in all the Eighteen (18) Local Government Area in Cross River State. Eighty seven thousand, five hundred and thirty three (87,533) valid questionnaire were received back. Nine hundred (900) of the people reported that they do not smoke any cigarette. Table 1 shows the total number of people who smoke cigarette. Table 2a,b show the total number of patients with smoking related diseases. Most of these patients with smoking related diseases such as decrease in lung function, increase of heart attack, Respiratory diseases, cancer, asthma, and other health effects are having those disease conditions as a result of their smoking habits.
Natural destruction is the matter of concern all over the world nowadays. Recent conference of World Health Organization on health concern from natural destruction was focusing on the causes made by the humans. Humans had a good relationship with nature before but with the modernization of humans, the relationship has been broken down. The nature is turning into the destruction by humans undoubtedly. So, humans are definitely always responsible for natural destruction because of unorganized urbanization, industrialization and greenhouse gases.

Our environment is constantly changing. There is no denying that. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. With a massive influx of natural disasters, warming and cooling periods, different types of weather patterns and much more, people need to be aware of what types of environmental problems our planet is facing.
Green House Gases
Greenhouse gases, including Chlorofluorocarbons (CFCs), are gases that contribute to the greenhouse effect. They allow the Sun's energy to reach Earth's surface but limit heat loss. Rising atmospheric concentrations of these gases could lead to higher temperatures and significant climate change. The next 50 years may see altered weather patterns, rising sea levels, and desert shifts. Human activity is dependent on climate, impacting food production, water supplies, construction, energy usage, transportation, and flood protection.
Causes
Greenhouse gases, which allow solar radiation to warm Earth during the day, contribute to its average temperature of 15 degrees Celsius. The increase in carbon dioxide concentration from 280 ppm (PPM means parts-per million and Percent means per hundred) in 1800 to 359 ppm in 1994 is attributed to increased use of fossil fuels, decreasing forest cover, and methane release from agricultural practices. If these levels continue to rise, global temperatures may reach 1 to 4 degrees Celsius higher by the mid21st century.Future Impact
Greenhouse warming is expected to cause severe stress on natural ecosystems, desert expansion, melting polar ice caps, ocean thermal expansion, more extreme weather events, and displacement of traditional agricultural areas. Rising sea levels are the most significant hazard, with glaciers melting and sea water expanding. This change will increase the frequency and severity of extreme events, affecting human health and living standards. The most vulnerable will experience the most severe impacts, necessitating concrete action to control pollution sources and mitigate potential impacts.
Environmental Awareness
Human activities, including urbanization, industrialization, and social structures, are posing ecological problems due to excessive use and misuse of natural resources. This imbalance affects energy budgets and climate change. To maintain ecological balance, mass awareness, afforestation, deforestation prevention, judicious resource use, pollution control, and environmentally respectful development is crucial, achieved through mass media, green marches, and environmental weeks.Salient Features of Environmental Awareness
Environmental education is crucial for controlling pollution, conserving resources, and maintaining ecological balance. NGOs play a vital role in educating people, particularly secondary school children. It covers various aspects of the environment, including atmosphere, earth, water, plants, animals, natural resource management, air, soil, and geological formations. It aims to create awareness, develop habits, promote values, and guide problem-solving and decision-making. It leads to positive attitudes and commitment of environment protection. It can be achieved by:
1. Gaining an understanding of the composition and operation of the inanimate natural system, as well as how it interacts with living things.
2. Realizing that all living things

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
4. Top 30 environmental issues
Although the top 30 environmental issues that face
the planet can be at best “subjective” we have
attempted to aggregate and prioritise the list in order
to put things into perspective.
We have also accompanied each of the
environmental issues with a video that explains the
matter in depth. You can view the clip by pressing
the play button on the image.
5. 1. Over Population growth and poverty
Without a doubt the biggest issue facing the environment is over population of
humans. All other major environmental issues flow from the very fact that we are over
populating the planet.
The worlds population has tripled in the last 60 years placing stress on every aspect of
the environment. More land is developed every day to accommodate the urban
spread.
In 1950 the population stood at 2,555,982,611 compared to 2012 which it now stands
at over 7,000,000,000. The actual maths is that the worlds population has increased
by almost 3 times. That is staggering when you think about it. That figure is increasing
even as we speak!
The rate of population growth is one of the fastest and according to estimates it would
double in just 25 years. What is obvious from this is, if the population continues to
grow at this rate, it would take a severe toll in the environment. Unfortunately Pakistan
is not endowed with resources required to sustain such a huge population.
6. 2. Climate Change and global warming
The most controversial and political of the top 10 environmental issues.
Recently an overwhelming majority of climate scientists, believe that human
activities are currently affecting the climate and that the tipping point has
already been passed. In other words, it is too late to undo the damage that
climate change has done to the environment.
At this stage the best we can do is regulate the further impact upon the
environment by developing more environmentally friendly methods of energy
production by reducing the mining and burning of fossil fuels.
The climate is changing. The earth is warming up, and there is now
overwhelming scientific consensus that it is happening, and human-induced.
With global warming on the increase and species and their habitats on the
decrease, chances for ecosystems to adapt naturally are diminishing.
7. 3. Loss of Biodiversity and Land use
The loss of biodiversity on the planet can be directly related to the
behaviours of human beings. Humans have destroyed and continue to
destroy the habitats of species on a daily basis.
When we exterminate one species, it has a knock on effect in the food chain
which in turn upsets the Eco-systems inter dependent on one another.
The catastrophic impact of loss of biodiversity is likely to affect the planet for
millions of years to come. The current loss of biodiversity is also being
named “The Sixth Extinction”
8. 4. The Phosphorus and Nitrogen Cycles
Although the effect of human activities on the carbon cycle is better known, the lesser
known effect on the cycle of Nitrogen actually has a greater impact on the
environment.
The human race’s use and abuse of nitrogen has been one of the most beneficial
technologies for our own species for decades. Every year, humans convert an
estimated 120 million tons of nitrogen from the atmosphere into reactive forms such
as nitrates, mainly in the production of nitrogen-based fertilizer for crops and in the
use of food additives.
The run off from crops into our oceans has a negative effect upon phytoplankton
which is responsible for the production of of most of the oxygen in our air.
9. 5. Water:
Many experts believe that in the near future water will become a commodity
just like Gold and Oil. Some experts say that wars will be fought over who
owns the water supply.
Currently, one third of humans have inadequate access to clean, fresh water.
The number is expected to increase by to up to two thirds by 2050. That is
that two thirds of the worlds population will not have access to clean
water.Over population, demand and pollution from industry is to blame.
10. 6. Ocean Acidification
A direct effect of excessive CO2 production. The oceans absorb as much as 25% of
all human carbon dioxide emissions. The gas then combines with other elements to
form compounds such as carbolic acid.
Over the last 250 years, surface acidity of the ocean has increased by an estimated
30%. The acidity is expected to increase by 150% by 2100.
The effect of over acidification of the oceans on sea creatures such as shellfish and
plankton is similar to osteoporosis in humans. The acid effectively is dissolving
the skeletons of the creatures.
The effect of ocean acidification may soon challenge marine life on a scale that the
planet has not seen for millions of years.
11. 7. Pollution of water , air , soil and noise
Pollution of air, water and soil by chemical compounds that take many years to
breakdown. Most of these chemicals are the bi-products of our modern lifestyle and
are created by industry and motor vehicle exhaust.
Pollution isn’t just limited to the air. Soil is another place where pollution is starting to
take hold.
Common toxic substances include heavy metals, nitrates and plastic.
A lot of the plastics that are discarded by humans end up the ocean. These plastics
tend to go unseen by humans as the pollution is usually blown out to sea by prevailing
winds.
12. 8. Ozone Layer Depletion
Depletion of our ozone layer has been mainly attributed to the release of chemical
pollution containing the chemicals Chlorine and Bromide. Once the chemicals reach
the upper atmosphere, they cause ozone molecules to break apart causing a hole to
form, the largest of which is over the Antarctic.
The atmosphere blocks many of the harmful UV rays from the sun that can damage
living tissue. In an effort to reduce this process, CFCs have been banned in many
manufacturing processes and products.
According to the Environmental Protection Agency, one atom of chlorine can break
down more than 100, 000 ozone molecules.
13. 9.Over Fishing:
It is estimated that by 2050 that there will be no fish left in the sea. I actually
think that this is the single most devastating truth that I have discovered.
The extinction of many fish species is due to humans over fishing the
oceans to supply an ever increasing populations demand for sea food.
The collapse of the Atlantic Cod Fishery is one such example of how
humans have exploited the planet’s natural resources to the brink of
extinction.
14. 10. Deforestation:
Since 1990 half of the worlds rain forests have been destroyed. The clearing
of forests continue at an alarming rate.
To add to the worry a recent phenomenon has been added to the list.
Trees are now dying globally at a rate never before seen.
15. 11.Acid Rain
Acid rain occurs due to the presence of certain pollutants in the atmosphere. Acid rain
can be caused due to combustion of fossil fuels or erupting volcanoes or rotting
vegetation which release sulfur dioxide and nitrogen oxides into the atmosphere. Acid
rain is a known environmental problem that can have serious effect on human health,
wildlife and aquatic species
16. 12. Public Health Issues
The current environmental problems pose a lot of risk to health of humans, and animals.
Dirty water is the biggest health risk of the world and poses threat to the quality of life
and public health. Run-off to rivers carries along toxins, chemicals and disease
carrying organisms. Pollutants cause respiratory disease like Asthma and cardiac-
vascular problems. High temperatures encourage the spread of infectious diseases
like Dengue.
17. 13.Genetic Engineering
Genetic modification of food using biotechnology is called genetic engineering.
Genetic modification of food results in increased toxins and diseases as
genes from an allergic plant can transfer to target plant. Genetically modified
crops can cause serious environmental problems as an engineered gene
may prove toxic to wildlife. Another drawback is that increased use of toxins
to make insect resistant plant can cause resultant organisms to become
resistant to antibiotics.
18. 14. Urban Sprawl
Urban sprawl refers to migration of population from high density urban areas
to low density rural areas which results in spreading of city over more and
more rural land. Urban sprawl results in land degradation, increased traffic,
environmental issues and health issues. The ever growing demand of land
displaces natural environment consisting of flora and fauna instead of being
replaced.
19. 15. Waste disposal
The over consumption of resources and creation of plastics are creating a
global crisis of waste disposal. Developed countries are notorious for
producing an excessive amount of waste or garbage and dumping their
waste in the oceans and, less developed countries. Nuclear waste disposal
has tremendous health hazards associated with it. Plastic, fast food,
packaging and cheap electronic wastes threaten the well being of humans.
Waste disposal is one of urgent current environmental problem.
20. 16. Natural Resource Depletion
Natural resource depletion is another crucial current environmental problems.
Fossil fuel consumption results in emission of Greenhouse gases, which is
responsible for global warming and climate change. Globally, people are
taking efforts to shift to renewable sources of energy like solar, wind, biogas
and geothermal energy. The cost of installing the infrastructure and
maintaining these sources has plummeted in the recent years.
21. 17. Wild Life Conservation
More than 40 percent of Americans expressed concern about wildlife
conservation and associated environmental issues, such as endangered
species, animal and plant extinction, coral bleaching, introduction of invasive
species, poaching, and loss of natural animal habitats resulting in relocation
and a break in the food chain.
22. 18. Species Extinction
An alarming rate of species extinction is happening worldwide. As of 2010,
the rate of loss is estimated to be more than 1,000 times the normal rate.
Greater preservation tactics and strategies are needed with laws put into
place to protect species. Once more, manmade pollution is the culprit along
with land encroachment by developers. Both causes are created by
consumer demands as people branch out into areas that were once remote
habitats for various species.
23. 19. Used lead–acid battery recycling.
These are used everywhere, and are also known by the name of “car
batteries”. Although they can be recharged, after a number of cycles, they
loose their ability to hold energy and become hazardous waste. The main
problem here is the release of lead. The fact that in many countries the
recycling operations and facilities are located in areas with very limited
control, makes the problem a lot more serious.
24. 20. Desertification -
The spread of desert-like conditions in arid or semi-arid areas, due to
overgrazing, loss of agriculturally productive soils, or climate change.
25. 21.
Greenhouse gas
A gas that "traps" infrared radiation in the lower atmosphere causing
surface warming; water vapor, carbon dioxide, nitrous oxide,
methane, hydrofluorocarbons, and ozone are the primary
greenhouse gases in the Earth's atmosphere.
26. 22. Overgrazing
The grazing of animals on plant material faster than it can naturally regrow
leading to the permanent loss of plant cover, a common effect of too many
animals grazing limited range land.
27. 23. Slash-and-burn agriculture
A rotating cultivation technique in which trees are cut down and burned in
order to clear land for temporary agriculture; the land is used until its
productivity declines at which point a new plot is selected and the process
repeats; this practice is sustainable while population levels are low and time
is permitted for regrowth of natural vegetation; conversely, where these
conditions do not exist, the practice can have disastrous consequences for
the environment
28. 24 .Soil degradation
Damage to the land's productive capacity because of poor
agricultural practices such as the excessive use of pesticides or
fertilizers, soil compaction from heavy equipment, or erosion of
topsoil, eventually resulting in reduced ability to produce agricultural
products.
29. 25. Soil erosion
The removal of soil by the action of water or wind,
compounded by poor agricultural practices, deforestation,
overgrazing, and desertification.
30. 26. Ultraviolet (UV) radiation -
a portion of the electromagnetic energy emitted by the sun and naturally filtered
in the upper atmosphere by the ozone layer; UV radiation can be harmful to
living organisms and has been linked to increasing rates of skin cancer in
humans
31. 27. Natural disasters
Pakistan is subject to frequent earthquakes which are often severe
(especially in north and west) and severe flooding along the Indus after
heavy rains (July and August). Landslides are common in the northern
mountains.
32. 28. Destruction of natural habitats
The area has been heavily settled for several centuries, large swathes of
natural vegetation, particularly in the lowlands, have been cleared for
agriculture and urban development.
33. 29 .Soil contamination
Soil Contamination: Soil erosion, soil conservation, soil
salination, and soil contamination by waste, pesticides,
and lead worries
