Antarctica is the coldest, windiest, and driest continent located at Earth's south pole. It is surrounded by the southern ocean and is covered in thick layers of ice, with temperatures reaching as low as -129 degrees Fahrenheit. No permanent residents live on the continent, though some scientists live and work at research stations. The only native land animals are insects, spiders, and small creatures, while the surrounding ocean is home to various seabirds, seals, whales, and penguins that have adapted to survive in Antarctica's extreme conditions. As global warming causes Antarctic ice shelves and glaciers to melt, it threatens the survival of the native wildlife and may contribute to rising sea levels worldwide.
Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra.
Characteristics of Tundra
Extremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations

Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity

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.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

"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.

2. Antarctica is a continent at the southern most part of the
earth. It contains the south pole and is surrounded by the
southern ocean. The Atlantic, Pacific, and Indian oceans all
touch Antarctica.
3. Antarctica is the 5th largest continent. It is also the coldest,
windiest, and driest continent. It is actually considered to be
a desert due to the small amount of rain that falls. A desert
does not have to be covered in sand or in a hot place.
4. The temperature in Antarctica has reached -129
degrees farenheit. There are no people who live there
permanently. Antarctica is so cold that people could
not live there.
5. People in Antarctica live on research stations. These
people are scientists. This is a photograph of the
Neumayer Research Station. The Neumayer station can
sleep up to 40 people.
6. The coldest months are
June, July, August and
September. The
temperature is around -
22F.
The warmest months are
December and January
(the summer months).
The temperature is around
30 F although it can get
warmer.
Usually they only have
about 2 days of rain in the
whole year.
7. There are no schools in Antarctica as it is too cold for
children to live there year round. However, some children
live at the stations with their families and go to school at
the station.
8. In winter, so much
ice forms around
the continent's
coastlines that it
doubles in size.
Antarctica has
most of the
world's ice. Almost
the entire
continent is
covered in a thick
layer of ice.
Antarctica is a
white continent.
9. Not many animals can live in Antarctica because it
is so cold. In fact, the only animals that live on
Antarctica are insects, spiders and small
creatures. However, the sea is filled with life. Can
you guess which sea animal is in this photograph?
10. Some types of
penguins live in
Antarctica.
Penguins do not fly
but swim instead.
They love to eat
krill and fish.
Penguins spend half
their life in the
water and half
their life on land.
Gentoo Penguin
11. Emperor penguins are the only penguins to lay their eggs
on the ice. All other penguins lay their eggs on land or in
nests. After the female lays the egg, the male keeps it
warm for 2 months. He doesn't even eat during that time.
12. Emperor penguins huddle together to stay warm. The
penguins in the middle are the warmest. When they are warm
enough, they move to the outside to let other penguins take a
turn in the middle.
13. Leopard seals have black-spotted coats. They spend most
of their time in the cold water looking for penguins to eat.
Seals have a thick layer of fat, called blubber which
protects them from the cold.
14. Whales are the world's largest mammals, found in
Antarctica.There are up to 8 whale species to encounter
in Antarctica. Humpbacks are the most sighted, followed
15. Killer whales also known as Orca whales can also be found in
Antarctica.
16. Krill are very important sea animals because they are
eaten by whales, seals, penguins and squid.
17. The Snow Petrel is one of only three birds that lives in
Antarctica.
18. An ice shelf is thick
floating ice which is
flat on top.
An iceberg is ice
that breaks off
from the ice shelf.
Icebergs are
everywhere in
Antarctica.
Ross Ice Shelf
19. Here you can see the flat top of the Ross ice shelf.
20. Did you know that underneath some ice shelves
there are subglacial volcanoes? These volcanoes
are contributing to the ice melt that is occurring in
West Antarctica.
21. The orange areas mean the temperature is getting warmer
in parts of Antarctica. Warmer temperatures mean the ice
is melting and the sea level is getting higher. No one really
knows how this will affect the rest of the world in the
future.
22. We must reduce global warming to protect
the habitat of animals in Antarctica.
Ice melting from a glacier
23. Protect the animals'
habitats. They need
the ice to survive.
Protect our earth for
the future.
Reduce global warming by
turning off the lights when
you leave the room.
