"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.

The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.
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.

3. INTRODUCTION: What is Climate Change?
Climate is the average weather at a given point and time of year,
over a long period (typically 30 years).
We expect the weather to change a lot from day to day, but we
expect the climate to remain relatively constant.
If the climate doesn’t remain constant, we call it climate change.
The key question is what is a significant change – and this depends
upon the underlying level of climate variability
Crucial to understand difference between climate change and
climate variability…
4. About Climate Change
This graph illustrates the change in global surface temperature relative to
1951-1980 average temperatures. Eighteen of the 19 warmest years all have
occurred since 2001, with the exception of 1998. The year 2016 ranks as the
warmest on record.
5. POPULATION AND ENVIRONMENT
“Many people worry that population growth will
eventually cause an environmental catastrophe.
However, the problem is bigger and more complex
than just counting bodies.”
6. OUR GROWING POPULATION…..
• We humans are remarkable creatures.
• From our humble beginnings in small pockets of Africa, we have
evolved over millennia to colonize almost every corner of our planet.
• We are clever, resilient and adaptable―perhaps a
little too adaptable.
• In 2015 the world population is more than 7.3 billion people.
• That’s more than seven billion three hundred million bodies that
need to be fed, clothed, kept warm and ideally, nurtured and
educated.
• More than 7.3 billion individuals who, while busy consuming
resources, are also producing vast quantities of waste, and our
numbers continue to grow.
• The United Nations estimates that the world population will reach
9.2 billion by 2050.
7. For most of our existence the human population has grown very slowly, kept in
check by disease, climate fluctuations and other social factors.
It took until 1804 for us to reach 1 billion people. Since then, continuing
improvements in nutrition, medicine and technology have seen our population
increase rapidly.
Human population has seen exponential growth over the past few hundred
years. Data source: Our World in Data.
The impact of so many humans on
the environment takes two major
forms:
•consumption of resources such as
land, food, water, air, fossil fuels
and minerals
•waste products as a result of
consumption such as air and water
pollutants, toxic materials and
greenhouse gases
OUR GROWING POPULATION…..
8. • Given that records show that climate is changing, the next question is the degree to which
human activities are responsible.
• The time series below shows the five-year average variation of global surface temperatures.
Dark blue indicates areas cooler than average. Dark red indicates areas warmer than
average.
• Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released
through human activities such as deforestation and burning fossil fuels, as well as natural
processes such as respiration and volcanic eruptions.
OUR GROWING POPULATION…..
9. MORE THAN JUST NUMBERS…
• Many people worry that unchecked population growth will eventually cause
an environmental catastrophe.
• This is an understandable fear, and a quick look at the circumstantial
evidence certainly shows that as our population has increased.
• The health of our environment has decreased.
• The impact of so many people on the planet has resulted in some scientists
coining a new term to describe our time—the Anthropocene epoch.
“However, while population size is part of the problem, the issue is bigger and
more complex than just counting bodies.”
There are many factors at play. Essentially, it is what is happening within those
populations—their distribution (density, migration patterns and
urbanisation), their composition (age, sex and income levels) and, most
importantly, their consumption patterns—that are of equal, if not more
importance, than just numbers.
10. LAND-COVER CHANGE AND DEFORESTATION
• The conversion of natural lands to croplands, pastures, urban areas, reservoirs,
and other anthropogenic landscapes represents the most visible and pervasive
form of human impact on the environment .
• Today, roughly 40% of Earth’s land surface is under agriculture, and 85% has
some level of anthropogenic influence.
• Although the world’s population is now 50% urban, urban areas occupy less
than three percent of Earth’s surface .
• We can conclude from this that large-scale land-cover change is largely a rural
phenomenon, but many of its drivers can be traced to the consumption
demands of the swelling urban middle classes.
• As with the demographic and development transitions, the world remains
divided in various stages of the land-use transition.
• Although the developed nations have achieved replacement (2.1 births per
woman) or below replacement-level fertility, have urbanized, and have
economies dominated by service and technology industries, developing
nations continue to experience rapid population growth, remain largely rural,
and have labor forces concentrated in the primary sector.
12. ENVIRONMENTAL DEGRADATION FORMULA :
The IPAT equation, first devised in the 1970s, is a way of determining environmental
degradation based on a multiple of factors.
At its simplest, it describes how human impact on the environment (I) is a result of
a multiplicative contribution of population (P), affluence (A) and technology (T).
I = P x A x T
Environmental impact (I) can be considered in terms of resource depletion and
waste accumulation; population (P) refers to the size of the human population;
affluence (A) refers to the levels of consumption by that population; and technology
(T) refers to the processes used to obtain resources and transform them into useful
goods and wastes.
the IPAT equation encouraged people to see that environmental problems are
caused by multiple factors that when combined produced a compounding effect.
More significantly, it showed that the assumption of a simple multiplicative
relationship among the main factors generally does not hold—doubling the
population, for example, does not necessarily lead to a doubling of environmental
impact
13. POPULATION SIZE
• Focusing solely on population number obscures the multifaceted
relationship between us humans and our environment, and makes it easier
for us to lay the blame at the feet of others, such as those in developing
countries, rather than looking at how our own behavior may be negatively
affecting the planet.
• It's no surprise that as the world population continues to grow, the limits of
essential global resources such as potable water, fertile land, forests and
fisheries are becoming more obvious.
But how many people is too many? How many of us can
Earth realistically support?
14. POPULATION SIZE
Influenced by the work of Thomas Malthus, 'carrying capacity' can be
defined as the maximum population size an environment can sustain
indefinitely.
• Debate about the actual human carrying capacity of Earth dates back
hundreds of years.
• The range of estimates is enormous, fluctuating from 500 million people to
more than one trillion.
• Scientists disagree not only on the final number, but more importantly
about the best and most accurate way of determining that number—
hence the huge variability.
15. STRATEGIC IMPERATIVES : CARRYING CAPACITY
How can this be? Whether we have 500 million people or one trillion, we still
have only one planet, which has a finite level of resources.
• People around the world consume resources differently and unevenly.
• An average middle-class American consumes 3.3 times the subsistence level of
food and almost 250 times the subsistence level of clean water.
• So if everyone on Earth lived like a middle class American, then the planet
might have a carrying capacity of around 2 billion. However, if people only
consumed what they actually needed, then the Earth could potentially support
a much higher figure.
But we need to consider not just quantity but also quality—Earth might be able to
theoretically support over one trillion people,
But what would their quality of life be like?
Would they be scraping by on the bare minimum of allocated resources, or
would they have the opportunity to lead an enjoyable and full life?
16. POPULATION DISTRIBUTION:
More importantly, could these trillion people cooperate on the scale required,
or might some groups seek to use a disproportionate fraction of resources? If
so, might other groups challenge that inequality, including through the use of
violence?
Yet to be answered…..
• The ways in which populations are spread across Earth has an effect on the
environment.
• Developing countries tend to have higher birth rates due to poverty and
lower access to family planning and education, while developed countries
have lower birth rates.
• In 2015, 80 per cent of the world’s population live in less-developed nations.
These faster-growing populations can add pressure to local environments.
17. While many enthusiasts for centralization and urbanization argue this allows
for resources to be used more efficiently.
In developing countries this mass movement of people heading towards the
cities in search of employment and opportunity often outstrips the pace of
development, leading to slums, poor (if any) environmental regulation, and
higher levels of centralized pollution.
Even in developed nations, more people are moving to the cities than ever
before.
The pressure placed on growing cities and their resources such as water,
energy and food due to continuing growth includes pollution from additional
cars, heaters and other modern luxuries, which can cause a range of localized
environmental problems.
Population distribution:
18. Humans have always moved around the
world. However, government policies,
conflict or environmental crises can
enhance these migrations, often
causing short or long-term
environmental damage. For example,
since 2011 conditions in the Middle
East have seen population transfer (also
known as unplanned migration) result
in several million refugees fleeing
countries including Syria, Iraq and
Afghanistan.
The sudden development of often huge
refugee camps can affect water
supplies, cause land damage (such as
felling of trees for fuel) or pollute
environments (lack of sewerage
systems).
Population distribution:
Unplanned migration is not only difficult for refugees. Having so
many people living so closely together without adequate
infrastructure causes environmental damage too.

19. • The composition of a population can also affect the surrounding environment. At
present, the global population has both the largest proportion of young people
(under 24) and the largest percentage of elderly people in history. As young people
are more likely to migrate, this leads to intensified urban environmental concern.
• Life expectancy has increased by approximately 20 years since 1960. While this is a
triumph for mankind, and certainly a good thing for the individual, from the planet's
point of view it is just another body that is continuing to consume resources and
produce waste for around 40 per cent longer than in the past.
• Population income is also an important consideration. The uneven distribution of
income results in pressure on the environment from both the lowest and highest
income levels.
• The least developed nations tend to have lower levels of industrial activity, resulting
in lower levels of environmental damage. The most developed countries have found
ways of improving technology and energy efficiency to reduce their environmental
impact while retaining high levels of production. It is the countries in between—
those that are developing and experiencing intense resource consumption (which
may be driven by demand from developed countries)—that are often the location of
the most environmental damage.
Population composition
20. • While poverty and environmental degradation are closely interrelated, it is
the unsustainable patterns of consumption and production, primarily in
developed nations, that are of even greater concern.
• It’s not often that those in developed countries stop and consider our own
levels of consumption. For many, particularly in industrialised countries, the
consumption of goods and resources is just a part of our lives and culture,
promoted not only by advertisers but also by governments wanting to
continually grow their economy.
• Culturally, it is considered a normal part of life to shop, buy and consume,
to continually strive to own a bigger home or a faster car, all frequently
promoted as signs of success. It may be fine to participate in consumer
culture and to value material possessions, but in excess it is harming both
the planet and our emotional wellbeing.
Population consumption
21. • The environmental impact of all this
consumption is huge. The mass
production of goods, many of them
unnecessary for a comfortable life, is
using large amounts of energy, creating
excess pollution, and generating huge
amounts of waste.
• Consumption patterns and resource use
are very high in some parts of the
world, while in others—often in
countries with far more people—they
are low, and the basic needs of whole
populations are not being met.
Population distribution:
More clothes, more gadgets, bigger cars, bigger
houses—consuming goods and resources has big
effects on our planet.
Image source: n.karim / Flickr.
• Countries with the fastest population growth also had the slowest increases in
carbon emissions. The reverse was also true—for example the population of
North America grew only 4 per cent between 1980 and 2005, while its carbon
emissions grew by 14 per cent
22. Individuals living in developed countries have, in general, a much
bigger ecological footprint than those living in the developing world. The
ecological footprint is a standardized measure of how much productive land
and water is needed to produce the resources that are consumed, and to
absorb the wastes produced by a person or group of people.
ECOLOGICAL FOOTPRINT
“Today humanity uses the equivalent of 1.5 planets to provide the resources we
use and absorb our waste. This means it now takes the Earth one year and six
months to regenerate what we use in a year.”
An American has an ecological footprint almost 9
times larger than an Indian—so while the
population of India far exceeds that of the United
States, in terms of environmental damage, it is the
American consumption of resources that is causing
the higher level of damage to the planet.
Global Footprint
23. The world population is growing by approximately 74
million people per year
Population growth is not evenly distributed across the
globe
Scientists are yet to conclusively determine the human
‘carrying capacity’ of Earth
Population is only one of many factors influencing the
environment
We have consumed more resources in the last 50 years
than the whole of humanity before us
The 20th century saw the biggest increase in the world’s
population in human history
ESSENTIALS
25. A BIGGER PIE: TECHNICAL INNOVATION
This theory looks to innovation and technology as Earth’s saviour, not only to
extend the planet’s human carrying capacity, but to also improve the quality
of life for each individual. Advances in food production technologies such as
agriculture, water purification and genetic engineering may help to feed the
masses, while moving away from fossil fuels to renewable power sources such
as wind and solar will go some way to reducing climate change.
‘Economic decoupling’ refers to the ability of an economy to grow without
corresponding increases in environmental pressure. In 2014 the United
Nations Environment Programme (UNEP) released a report titled
'Decoupling 2', which explored the possibilities and opportunities of
technology and innovation to accelerate decoupling, and an analysis of how
far technical innovation can go.
26. EDUCATION AND POLICY CHANGE
This theory is based on demographic transition, effectively finding ways to
slow or stop population growth resulting in fewer people fighting for
resources or ‘slices’ of pie.
Birth rates naturally decline when populations are given access to sexual and
reproductive healthcare, education for boys and girls beyond the primary
level is encouraged and made available, and women are empowered to
participate in social and political life. Continuing to support programs and
policies in these areas should see a corresponding drop in birth rates.
Similarly, as the incomes of individuals in developing countries increase, there
is a corresponding decrease in birth rates. This is another incentive for richer
countries to help their poorer neighbours reach their development potential.
Providing a health, educational or financial incentive has also proven to be
effective in combating some population issues. For example, paying money to
people with two or fewer children or allowing free education for families with
a single child has been trialled with some success.
27. BETTER MANNERS: LESS IS MORE
• The better manners approach seeks to educate people about their actions
and the consequences of those actions, leading to a change in behaviour.
• This relates not only to individuals but also governments.
• Individuals across the world, but particularly in developed countries, need
to reassess their consumption patterns.
• Numerous studies have shown that more ‘stuff’ doesn't make people
happier anyway.
• We need to step back and re-examine what is important and actively find
ways to reduce the amount of resources we consume.
• Taking shorter showers, saying no to single-use plastics, buying less,
recycling our waste and reviewing our mode and frequency of travel may
seem trivial, but if millions around the world begin to do it as well, the
difference will begin to add up.
28. BETTER MANNERS: LESS IS MORE
• Governments too need to instigate shifts in environmental policy to
protect and enhance natural areas, reduce CO2 and other greenhouse gas
emissions, invest in renewable energy sources and focus on conservation
as priorities.
• Developing countries should be supported by their more developed
neighbours to reach their development goals in sustainable, practical
ways.
• there is no single, easy solution.
All three options must be part of a sustainable future.
29. Where to from here?
• Population is an issue that cannot be ignored. While we can all do our bit
to reduce our own global footprint, the combined impact of billions of
other footprints will continue to add up.
• There are many who believe that if we do not find ways of limiting the
numbers of people on Earth ourselves, then Earth itself will eventually find
ways of doing it for us.
• Interestingly, despite population increase being such a serious issue, the
United Nations has held only three world conferences on population and
development (in 1945, 1974 and 1994).
• the world are beginning to recognize the seriousness and importance of
the situation, and are taking steps to reduce the environmental impacts of
increasing populations and consumption such as through pollution
reduction targets for air, soil and water pollutants.
• The United Nations Climate Change Conference in Paris, December 2015,
is one example; however any international policies need to be backed up
by workable solutions at the individual, local and regional level.
30. Conclusion
With more than 7.3 billion people on the planet, it’s easy to assume
someone else will tackle and solve the issue of population and
environment. Yet it is an issue that affects us all, and as such we’re
all responsible for working towards a sustainable future in which
everyone is able to enjoy a good quality of life without destroying
the very things we rely on to survive. It’s possible, but it will take
the combined and coordinated efforts of individuals, communities,
and governments to get there.
