"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.

• Introduction
• What is air Pollution?
• The main sources of air pollution
• Air Pollutants
• Causes of Air Pollution
• Effects of Air Pollution
• Control Measures For Air
Pollution
• Refference
3. introduction
• Air is essential for life it self,
without it we could survive only a
few minutes.
• It constitutes immediate physical
environment of living organisms
• The atmosphere is layered in to four
distinct which are: Troposphere,
stratosphere, mesosphere, and
thermosphere.
5. What is air Pollution?
• Air pollution consists of gases,
liquids, or solids present in the
atmosphere in high enough levels to
harm humans, other organisms, or
materials.
• There is no such place, where the air
can be found entirely pure and
uncontaminated.
6. According to World Health Organisation.
“Air pollution is defined as, substances put into air by the activity
of mankind into concentration sufficient to cause harmful effect to
his health, vegetables,property or to interfere with the enjoyment
of his property”
According to Indian Standards Institute.
“Air pollution is the presence in ambien atmosphere of substances,
generally resulting from the activity of man, in sufficient
concentration, present for a sufficient time and under
circumstances which interfere significantly with the comfort,
health or welfare of persons or with enjoyment of property”.
7.
8. The main sources of air
pollution
(a) AUTOMOBILES:
• Motor vehicles are a major source of air pollution
throughout the urban areas.
• They emit hydrocarbons, carbon monoxide, lead,
nitrogen oxides and particulate matter.
• In strong sunlight, certain of these hydrocarbons and
oxides of nitrogen may be converted in the atmosphere
into “photochemical” pollutants of oxidizing nature.
9. • In addition, diesel engines, when misused or badly
adjusted are capable of emitting black smoke and
malodorous, fumes.
10. (b) INDUSTRIES:
• Combustion of fuel to generate heat and power
produces smoke, sulphur dioxide, nitrogen oxides
and fly ash.
• Petrochemical industries generate hydrogen
fluoride, hydrochloric acid and organic halides.
• Many industries discharge carbon monoxide, carbon
dioxide, ozone, hydrogen sulphide and sulphur
dioxide.
• Industries discharge their wastes from high
chimneys at high temperature and high speed.
11. (c) Domestic sources :
• Domestic combustion of coal, wood or oil is a major
source of smoke, dust, sulphur dioxide and nitrogen
oxides.
(d) Tobacco Smoke:
• The most direct and important source of air pollution
affecting the health of many people .
• Even those who do not smoke may inhale the smoke
produced by others (“passive smoking”).
12. (e) Miscellaneous
• These comprise burning refuse, incinerators, pesticide
spraying, natural sources (e.g., wind borne dust, fungi,
molds, bacteria) and nuclear energy programmes. All
these contribute to air pollution.
14. (1) Carbon monoxide
• It is colorless , odorless gas , a product of
incomplete combustion of carbon containing
materials, such as in in automobiles,
industrial process, heating facilities and
incinerators
• Some widespread natural non biological and
biological sources have also been identified.
• Concentrations in urban areas depend on
weather and traffic density.
15. • Effect of CO pollution on the health:
• It causes harmful effect by reducing oxygeen delivery to
body organ , in extermelly high level it can cause death.
• CO’s affinity for Hb is 240–270 times greater than oxygen
and Fetal Hb has higher affinity for CO , so it competes
with O2 to bind (irreversibly) with haemoglobin.
• By this exposure to it reduce the oxygen -carrying
capacity of the blood to the heart, brain and other
organs .
• deprives body of O2 causing headaches, fatigue, MI and
impaired vision.
16. (2) Sulphur dioxide
• It is one of the several forms in which sulphur exists in air.
• The others include H2S,H2SO4and sulphate salts.
• Sulphur dioxide results from the combustion of sulphur
containing fossil fuel, and when coal and fuel oil are
burned.
• Domestic fires can also produce emissions containing
sulphur dioxide.
• Acid aerosol – sulphuric acid (H2S04)is a strong acid that
is formed from the reaction of sulphur trioxide gas (S03)
with water.
17. (3)Nitrogen Dioxide
• Nitric oxide (NO) is produced by combustion.
• Nitrogen dioxide (NO2), which has greater health effects, is a
secondary pollutant created by the oxidation of NO under
conditions of sunlight, or may be formed directly by higher
temperature
• combustion in power plants or indoors from gas stoves.
• Reddish, brown gas present in car exhaust and power plants.
• Levels of exposure to nitrogen dioxide that should not be
exceeded (WHO guideline levels) are respectively 400 μg/m3
(0.21 parts per million (ppm) for one hour and 150 μg/m3
(0.08 ppm) for 24 hours (WHO, 1987a).
18. (4)Particulate matter :
• represents a complex mixture of organic and inorganic
substances.
• Mass and composition tend to divide into two principal
groups :
1. coarse particles larger than 2.5 µm in aerodynamic
diameter, and fine particles smaller than 2.5 µm in
aerodynamic diameter.
• The smaller particles contain the secondarily formed
aerosols ,combustion particles and recompensed organic
and metal vapours.
19. • The large particles usually contain earth’s crustal
material and fugitive dust from roads and
industries.
• Particulate matter of respirable size may be
emitted from a number of sources, some of them
natural (e.g. Dust Storms)and many others that
are more widespread and more important (e.g.,
power plants and industrial processes, domestic
coal burning, industrial incinerators).
20. (5) Ground level ozone
• This is formed when pollutants such as nitrogen
oxides and volatile organic compounds (VOCs) react
in sunlight .
• High levels can cause breathing problems, reduce
lung function and trigger asthma symptoms.
• Ground level ozone can also seriously damage crops
and vegetation.
• Ozone is a powerful greenhouse gas and contributes
to global warming both directly and by reducing
carbon uptake by vegetation.
21. (5) Ground level ozone
• The WHO guidelines are 150–200
μg/m3 (0.076–0.1 ppm) for one
hour exposure and 100–200
μg/m3 (0.05-0.06 ppm) for 8 hour
exposures (WHO, 1987a)
22. Causes of Air Pollution
1. Anthropogenic Causes (Human Activity)
• Stationary Sources
• Mobile Sources
• Chemicals, Dust and Controlled Burn Practices
• Fumes
• Waste Deposition in Landfill
23. Natural Causes :
• Dust from Natural Sources
• Methane
• Radon Gas
• Volcanic Activity
2.
24. Effects of Air Pollution
• Acid Deposition
• Eutrophication
• Smog
• Loss of Ozone Layer
• Greenhouse Effect
25. Control Measures for Air
Pollution
• Minimising Air Pollutant: This is accomplished through
efficient distribution of land by making proper plans for
establishing industries and building residential
apartments.
• Diffusion of Source Locations: To a large extent. Pollution
can be controlled by diffusing various sources of
pollutants. Tall stacks should be used for industries and
thermal power plants
26. • So that pollutants are released at relatively higher
heights, where there are both horizontal and upward
movement of air, with less chances of downward
movement.
• Reduction at Source by Process Changes: This is done
through
