"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.
Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
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.
Artificial Reefs by Kuddle Life Foundation - May 2024punit537210
Situated in Pondicherry, India, Kuddle Life Foundation is a charitable, non-profit and non-governmental organization (NGO) dedicated to improving the living standards of coastal communities and simultaneously placing a strong emphasis on the protection of marine ecosystems.
One of the key areas we work in is Artificial Reefs. This presentation captures our journey so far and our learnings. We hope you get as excited about marine conservation and artificial reefs as we are.

WRI’s brand new “Food Service Playbook for Promoting Sustainable Food Choices” gives food service operators the very latest strategies for creating dining environments that empower consumers to choose sustainable, plant-rich dishes. This research builds off our first guide for food service, now with industry experience and insights from nearly 350 academic trials.
2. You may have noticed the blue parts of the maps. That’s
water. No, really.
• Oceans and seas are the saltwater parts.
• There are four main oceans (Pacific, Atlantic, Indian,
Arctic) although they’re really part of one big
interconnected ocean
3. • The ocean has warm and cool currents (they’re
represented by the red and blue arrows on the big
map)
• These currents affect world temperatures because
the water warms or cools the wind that blows over
them. Ever wonder why England, though it’s on the
same latitude as Canada isn’t nearly as cold or
snowy? It’s because of ocean currents.

8. Lakes, rivers, and streams
• Generally freshwater. There are saltwater lakes when
there are no outlets to the sea because the salt builds
up.
• The saltiest lake is the Dead Sea in Israel and
Jordan. It has no outlet and a high evaporation
rate, so the salt concentrates even more. It’s so
salty (about nine times that of the ocean), it can’t
support life.
• Its shores are also the lowest dry point on Earth:
about 1,350 feet below sea level (you’re currently
about 45 feet above sea level)

12. • And the salinity (saltiness) allows you to float
without effort. Like these guys:
13. That’s because the water is so much denser than you that
it makes you naturally buoyant.
Just don’t get the water in your eyes. It’ll sting.
14. Hydrologic Cycle
• Water evaporates from various sources, goes up into
the atmosphere, cools and condenses, comes down as
rain or snow, and the process starts over again. It’s
the cycle of water.
16. Water Table
• The water table is the point at which the ground and
rock becomes saturated with water.
17.
18. • The water table isn’t constant. It raises or lowers
depending on seasonal recharge from rain and also
from how much is pumped out.
19. • Overpumping can be a problem and can not only dry
up wells, but also dry up streams that are fed by
natural springs that use ground water.

22. Landforms
• Naturally formed features on the surface of the earth
• See pp. 34-35 for some different types (note that it’s
an illustration and they don’t all occur within so little
space)
23. • Continental shelf
• The point at which the edge of the continent drops
off to the deep part of the ocean.
24.
25. • The ocean floor has landforms as well as dry land.
26. • Relief is the difference
in elevation of a
landform from its
lowest to highest
points. The bigger the
difference, the greater
the relief.
27. • Topography is the combination and distribution of
different landforms in an area
