Plastic pollution involves the accumulation of plastic products in the environment that adversely affects wildlife, wildlife habitat, or humans.[1] Plastics that act as pollutants are categorized into micro-, meso-, or macrodebris, based on size.[2] The prominence of plastic pollution is correlated with plastics being inexpensive and durable, which lends to high levels of plastics used by humans.[3] However, it is slow to degrade.[4] Plastic pollution can unfavorably affect lands, waterways and oceans. Living organisms, particularly marine animals, can also be affected through entanglement, direct ingestion of plastic waste, or through exposure to chemicals within plastics that cause interruptions in biological functions. Humans are also affected by plastic pollution, such as through the disruption of the thyroid hormone axis or hormone levels. In the UK alone, more than 5 million tonnes of plastic are consumed each year, of which an estimated mere 24% makes it into recycling systems. That leaves a remaining 3.8 million tonnes of waste, destined for landfills.[5][6] Plastic reduction efforts have occurred in some areas in attempts to reduce plastic consumption and pollution and promote plastic recycling.

How to manage and utilize the Plastic Waste with the developed Technologies for Recycling.
Plastic is all around us. It forms much of the packaging for our food and drink. For many of us, it is throughout our home, our workplace, our car, the bus we take to and from work. It can be in our clothing, eyeglasses, teeth, toothbrush, computers, phones, dishes, utensils, toys. The list goes on, especially when you look around and begin to notice the plastic in your life.
Plastic is versatile, lightweight, flexible, moisture resistant, durable, strong and relatively inexpensive. It can be chemical resistant, clear or opaque, and practically unbreakable. These are wonderful useful qualities, and plastic plays many important roles in life on Earth, but the widespread use of plastic is also causing unprecedented environmental problems, and harbours serious health risks . Plastic should be used wisely, with caution and only when suitable alternatives do not exist or are not available.
Right now the Movement Of "Say No To Single Use Plastic" is on every where so i made this small presentation for Public Awareness. I Referred The Book Which is published By U.N.with Name single Use Plastic_sustainability.
I am sure it will motivate many by saying that NO TO SINGLE USE PLASTIC After watching this presentation.

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 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.

Chemistry of Plastic
1. CHEMISTRY OF PLASTIC
BY
DR SHABNUM ARA QAZI
ASSOCIATE PROFESSOR
GOVT. COLLEGE FOR WOMEN NAWAKADAL, SRINAGAR
2. • Plastic is the term commonly used to describe a wide range of
synthetic or semi-synthetic materials.
• The term” plastic” is derived from the Greek word “plastikos”
meaning fit for moulding.
• A wide range of Industrial plastic is made from petrochemicals.
Petrochemicals are the products made from petroleum,which is a
hydrocarbon mixture.
• All plastics are polymers but not all polymers are plastic. Plastic
polymers consist of chains of linked subunits called monomers
• Monomers are the building blocks of plastic.They form
polymers by forming chemical bonds or binding through a
process called polymerization.
4. Traditional Plastic Bags :
• Plastic bags are usually made from polyethylene, which consists of so long chains
of ethylene monomers. Ethylene is derived from natural gas and petroleum.
5. HISTORY OF POLYETHYLENE BAGS
• In 1965, one piece of polyethylene shopping bag was
patented by Swedish company Celloplast and designed by
engineer Sten Gustaf Thulin.
• He came up with an idea to protect environment from
deforestation.
• A rare novelty in the 1970s, plastic shopping bags are now an
omnipresent global product , produced at a rate of one
trillion a year.
• They are showing up in the darkest depths of the oceans, to
the summit of the Mount Everest and to the polar ice caps
creating major environmental challenges.
•
6. WHY IS PLASTIC HAZARDOUS!
• Plastic carry bags are manufactured using organic and inorganic
additives like colourants and pigments, plasticizers, antioxidants,
stabilizers and metals.
• Colourants and pigments are used to give bright colour to plastic carry
bags. Some of these are carcinogenic and likely to contaminate food
stuffs, if packed in these carry bags.
• Plasticizers are organic esters of low volatile nature. They can migrate to
food stuffs as a result of leaching. Plasticizers are also carcinogenic.
• Toxic metals like cadmium, mercury and lead when used in manufacturing
of plastic bags also leach out and contaminate the food stuffs. Cadmium
when absorbed in the low doses can cause vomiting and heart
enlargement. Lead exposure in long term may cause degeneration of
brain tissues.
7. • Microplastics are also consumed by people through
food and in the air. It’s estimated that globally, people
consume the equivalent of a credit card of plastic
every week, and it’s expected that there will be more
plastic than fish in the sea by 2050.
• The plastic typically used in bottles, bags and food
containers contain chemical additives such as
endocrine disruptors, which are associated with
negative health effects including cancers, birth defects
and immune system suppression in humans and
wildlife.
• Chemical leachates from plastic bags impair the
growth of the world’s most important microorganisms,
Prochlorococcus, a marine bacterium that provides
one tenth of the world’s oxygen.
8. DECOMPOSITION
It takes 1,000 years for a plastic bag to degrade in a landfill. Unfortunately,
the bags don't break down completely but instead photo-degrade, becoming microplastics
that absorb toxins and continue to pollute the environment.
Plastic Bags are said to present significant challenge in terms of recycling. Recycle facilities
do not have the capacity to recycle plastic bags and thus do not accept them. Therefore the
actual recycling rate for plastic bags is about 5%.
Since Plastic bags never degrade completely, which means that as more of them are
produced by companies, more are introduced into the environment. Therefore, the more the
amount of plastic bags, the more there is plastic pollution and its effects. Banning the use of
plastic bags will help reduce this great effect.
9. WAYS YOU CAN HELP AND MAKE PLASTIC BAG
FREE PLANET :
• Be the one to lead the change.
• Feel proud to get a chance to save mother earth and thus your
motherland.
• Revive old art and culture of using willow baskets and cloth
bags which will help to boost local economy also.
• Its everyone’s duty towards our motherland to Take
responsibility of one”s ownself and SAY A BIG NO to polythene
bags.
• let this pledge reach out to masses through you our dear students as
you are young and energetic and have the power to turn the tables just
starting from their own homes from today and onwards.
• Lets us all stand together and reduce polythene bag usage.
