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.
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 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.
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. WATER
Three fourth of the Earth’s surface is covered
with water.
It is one of the most important natural resource.
All living things depend on water.
It is also used in household purposes like
cleaning, cooking, washing, drinking, bathing
etc.
3. IMPORTANCE OF WATER
Most of the water found on earth is not fit for
drinking
Only about 3% of fresh water is found on earth.
Rain is an important source of fresh water.
We get rainfall for only 2-3 months.
We should save water.
4. SOURCES OF WATER
Rain is the main source of water. It fills up the
Rivers, lakes, ponds, streams, wells which are
the other important sources of water.
Wells- are used mainly in villages. Wells supply
underground water.
Tubewells- it has a tube or a pipe fitted to an
underground source of water. An electrical or
diesel pump is used to pump the water.
5. CANALS
Canals are small channels through which water
from rivers or dams are diverted to the fields.
They are dug to take water to where there is
water shortage.
Example – the Indira Gandhi canal.
DID YOU KNOW?!!!!!!
INDIRA GANDHI CANAL
IS THE LONGEST
IRRIGATION CANAL!!!!!!
6. DAMS
Dams are barriers constructed on rivers.
They stop the flow of river water and store it in
a reservoir.
They help in controlling floods.
Water stored is used for irrigation.
It is also used to produce energy.
Helps in development of fishing and navigation.
It is also called the multipurpose river valley
project.
7. RAIN WATER HARVESTING
Rain water harvesting is process of storing and
collecting rain water.
This stored water is used for drinking, irrigation
etc.
It is usually done in the areas where there is
scarcity of water.
