Water resources are classified as surface water, groundwater, water vapor, and ice. Water is essential but demand exceeds supply due to overuse by industries, agriculture, and communities. This causes water stress through pollution, depletion of groundwater, urbanization, and rainfall wastage. Even areas with high rainfall like Cherapunji face shortages, as rain washes away and infrastructure is lacking. Deforestation decreases carbon and water regulation and increases climate change, pollution, and soil degradation.

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.

"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.
Prevalence of Toxoplasma gondii infection in domestic animals in District Ban...Open Access Research Paper
Toxoplasma gondii is an intracellular zoonotic protozoan parasite, infect both humans and animals population worldwide. It can also cause abortion and inborn disease in humans and livestock population. In the present study total of 313 domestic animals were screened for Toxoplasma gondii infection. Of which 45 cows, 55 buffalos, 68 goats, 60 sheep and 85 shaver chicken were tested. Among these 40 (88.88%) cows were negative and 05 (11.12%) were positive. Similarly 55 (92.72%) buffalos were negative and 04 (07.28%) were positive. In goats 68 (98.52%) were negative and 01 (01.48%) was recorded positive. In sheep and shaver chicken the infection were not recorded.
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.
2. Sources
71% of earth’s surface is covered by water
Oceans,lakes,rivers,streams,glaciers,lakes,ponds,groundwater,vapour,
soil moisture
Classification
1. Surface water a)drinkable b)Non-drinkable(salty)
2. Water in solid form
3. Water in atmosphere
4. Groundwater
3.
4. Water Demand
Domestic Demand: Includes water required in private building for
drinking, bathing, gardening, sanitary purposes etc.
Public Demand: Represents the water demand for public utility
purposes like washing public parks, gardening, washing on roads,
fountain.
Industrial Demand: Represents the water demand of industries which
are earlier existing or likely to be started in future.
Commercial Demand: Water requirements for institutions, hotels,
colleges, offices
Fire Demand: In populated or industrial areas, fires generally break
out and may lead to serious problems. To control that problem, we
require a sufficient quantity of problem called as fire demand.
Water Demand required for thefts and wastes: Water lost in leakage
and stolen water due to unauthorized water connections
8. Overuse and Effects
1. Industry: manufacturing processes, cooling plants etc.
2. Agricultural practices: Over-irrigation
Agriculture causes the greatest threat to freshwater sources.
Increase in demand for food has led to the increase in demand in water,
especially surface water and groundwater
9. Community overuse: wells or surface water sources such as a nearby lake,
the amount of water that can be withdrawn can be very large. The amount of
water taken out can be more than the amount of water that flows back into
the source.
Residential overuse: The water used around the home in swimming pools,
washing the car, washing dishes and laundry, running a lawn sprinkler, taking a
bath or shower, and even flushing the toilet all use a tremendous amount of
water.
10. Stress on Water Resources
Reasons:
1. INDUSTRIAL WASTE: waste water discharged in rivers after
treatment do not meet environment norms. The sewage water
should be treated so that it is fit for bathing.
2. POLLUTION: available water resources in the country do not meet
the World Health Organization water quality standards because of
pollution caused by rapid industrialisation, urbanisation, poor
farming and irrigation practices.
3. URBANIZATION: India’s water pollution happens due to waste from
cities that house. Owing to poor infrastructure, cities are unable
to treat all the waste generated and the remaining is dumped
untreated. Only 38 per cent of the population in the cities have
access to sanitation and 78 per cent to clean drinking water.
11. Water stress reasons
RAINFALL WASTAGE: rainwater runoff goes into the sea, which
is a major wastage .The runoff also causes soil erosion,
flooding of water bodies
DEPLETING GROUNDWATER: amount of groundwater extracted
in India annually, is the highest in the world. Most of the
districts in the country are facing problems relating to poor
quality and shortage of groundwater,

13. Story of Cherapunji
“Water, water everywhere, but not a drop to drink”
Wettest place on earth.. Suffering from water shortage.
14. The problem is that Cherapunji lies atop a high limestone
plateau. Rain falling on the town drains away immediately,
finishing up on the plains of Bangladesh, far below.
Cherapunji faces acute water shortage, especially during
winter.
Heavy rain washes the topsoil every year, hampering farming
and reforestation efforts
People here often have to walk for miles to collect drinking
water from government-installed pipelines set up nearly 25
years ago. And even that supply, which comes twice a day, isn't
free from contamination by bacteria and runoff from the coal
mines.
The main cause is Decrease in annual rain fall and
deforestation.
No water reservoir to store water
15. Forest Resources
Grass, shrubs, plants,weeds,mangroves
Direct and indirect use of forest are as follows:-
1. Conserve soils
2. Products: Fruits,gum,neem,wax,honey,resins etc.
3. Rainfall
4. Wildlife
5. Maintain Carbon dioxide cycle
6. Tourism
16. Causes of deforestation
Industrialization, urbanization
Use of wood as fuel, timber
Mining
Agriculture
Over grazing
Human establishment
Effects of
deforestation
Climate changes:Rise of
temperature, fall in precipitation
Rise in CO2 level: Global warming
Decrease in groundwater
Rise in suspended matter in
atmosphere: increasing air
pollution
Soil degradation
Loss of ecological balance
