Global warming may also impact agriculture, cause economic damages, and allow diseases to spread into new regions.
Global warming is causing significant changes to the Earth's climate. Glaciers and ice sheets are melting, sea levels are rising, and extreme weather events are becoming more common. The scientific consensus is that human activities, such as burning fossil fuels and deforestation, have increased greenhouse gas levels and caused most of the warming observed since the mid-20th century. As temperatures continue to rise, the impacts on the environment, plants and animals, weather patterns, and human society will intensify and become more costly. Individual actions to reduce energy use and greenhouse gas emissions can help address the problem.
The document discusses global warming, defining related terms like the greenhouse effect and climate change. It explains that human activities like burning fossil fuels and deforestation are releasing excess greenhouse gases, accelerating the greenhouse effect and causing global warming. Potential consequences of unchecked global warming include rising sea levels, more extreme weather, and impacts on agriculture and food supply. The document also notes arguments against the existence of global warming and presents the authors' opinion that it is real and will affect the future.
Global warming cases and effects notes grade 5ChitraThadani1
Fossil fuels are a main cause of global warming when burned, as they release greenhouse gases like carbon dioxide into the atmosphere. Farming, especially cattle which release methane through burping and flatulence, is another key contributor. Deforestation, which is happening at an alarming rate for agriculture and palm oil production, removes trees that absorb carbon dioxide and releases more greenhouse gases. As the climate warms due to these factors, animal habitats are disappearing and scientists predict 20-30% of species could become extinct by 2050 if changes are not made. Humans will also be negatively impacted as weather patterns change, causing issues like rising sea levels and flooding in some areas. Individual actions like reducing waste, driving less, and making
Global warming poses grave dangers to our future if steps are not taken now to curb it. It is defined as the increase in Earth's temperature caused by human activities that release greenhouse gases. Burning fossil fuels, intensive farming, deforestation, and population growth all accelerate global warming. The consequences include more extreme weather, rising sea levels, spread of diseases, and threats to food and water supplies. To address this, a campaign aims to plant 100 million trees globally by October 2008 through initiatives like Mission Green Earth that encourage individuals to take action against the largest environmental problem.
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.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.

RoHS stands for Restriction of Hazardous Substances, which is also known as the Directive 2002/95/EC. It includes the restrictions for the use of certain hazardous substances in electrical and electronic equipment. RoHS is a WEEE (Waste of Electrical and Electronic Equipment).
4. Man-made Causes
Man-made causes probably do the most damage. There are many man-
made causes. Pollution is one of the biggest man-made problems.
Pollution comes in many shapes and sizes. Burning fossil fuels is one
thing that causes pollution. Fossil fuels are fuels made of organic matter
such as coal, or oil. When fossil fuels are burned they give off a green
house gas called CO2. Also mining coal and oil allows methane to
escape. How does it escape? Methane is naturally in the ground. When
coal or oil is mined you have to dig up the earth a little. When you dig
up the fossil fuels you dig up the methane as well.
5. Another major man-made cause of Global Warming is
population. More people means more food, and more
methods of transportation, right? That means more
methane because there will be more burning of fossil fuels,
and more agriculture. Now your probably thinking, "Wait a
minute, you said agriculture is going to be damaged by
Global Warming, but now you're saying agriculture is going
to help cause Global Warming?" Well, have you ever been
in a barn filled with animals and you smell something
terrible? You're smelling methane. Another source of
methane is manure. Because more food is needed we
have to raise food. Animals like cows are a source of food
which means more manure and methane. Another problem
with the increasing population is transportation. More
people means more cars, and more cars means more
pollution. Also, many people have more than one car.
6. Since CO2 contributes to global warming, the increase in
population makes the problem worse because we breathe
out CO2. Also, the trees that convert our CO2 to oxygen are
being demolished because we're using the land that we cut
the trees down from as property for our homes and buildings.
We are not replacing the trees (an important part of our eco
system), so we are constantly taking advantage of our
natural resources and giving nothing back in return.

8. Skin Cancer, Malaria, and the Hanta Virus are serious health risks of global warming
Malaria
Malaria is a disease that will increase during global warming. It is one of the earliest
recorded human diseases, and is spread by the bite of a female mosquito. Mosquitoes
breed in warm, wet places. With the increase of rain and warmth during global
warming, the population of mosquitoes will increase, making the risk of getting this
disease also increase. Malaria means "bad air" in Italian referring to the time when
people thought that it was caused by gases around areas where mosquitoes thrive.
When you are bitten by a infected mosquito, it sends parasites into your bloodstream.
These parasites keep reproducing, making the disease more devastating. Symptoms are
fever and chills that come and go, headache, weakness, and an enlarged spleen. An
enlarged spleen could rupture, or require surgery to remove. People can live without a
spleen, but not having one increases the risk of infections or other problems.
9. Hanta Virus
The Hanta Virus is a deadly respiratory disease carried by wild rodents.
With Global Warming, the population of rodents will soar because
there will be long periods of drought followed by warm, early spring,
and rodents thrive in these climate conditions.
If you come in contact with a rodent or if you breathe air that contains
their waste you could get the virus. Dogs and cats are not known to
carry the Hanta Virus. People most likely to get it are people who work
in fields, or install and fix things in basements or attics where rodents
can nest.
Some symptoms may be flu-like symptoms with fever and chills, you
may have a dry cough, nausea, vomiting, or diarrhea. You could
experience fatigue and have a hard time breathing because your lungs
could fill with fluid. If you have these symptoms please see a doctor
right away.
Although there is some cure in Asia for their type of virus, in the United
States ours is more devastating and we have treatments that enable
survival; but only if you seek treatment immediately.

the Centers for Disease Control and Prevention.

11. As Global Warming hits, we may not be able to do some of the activities we
used to. Of the big outdoor activities, swimming and fishing, they will be
limited with water. If you have a favorite water-hole to fish and swim in, it
could dry up. Some other problems are safety and health. We will have to
wear sunscreen more often than we used to. Also, we will need to drink more
water when we do physical activities outside. From gardening, to bike-riding
or jogging, you should take a water bottle with you.
If you are unprepared to go outside, you could get a sunburn or become
dehydrated. Some people will probably stay indoors more often and some
may love the extra heat and the sun shining more often. They may go outside
more. If you are outside a lot you could risk getting skin cancer. This risk will
most likely increase with the warming.

13. One of the major causes of global warming is an increase in CO2. Some scientists
think this will help plants. One of the things that will help plants is the weather will
be warmer, making a longer growing season. If the plants have a longer growing
season they will produce more fruit. Another thing is that more precipitation is
anticipated. The United States Environmental Protection Agency ( U.S.E.P.A ) predicts
a 7% increase in precipitation by the year 2060 and a 5 degree increase in the
temperature. If there is an increase in precipitation, the plants will have plenty of
water. Plus, plants breathe CO2 like we breathe oxygen. If there is warmer weather,
an increase in precipitation, and lots of CO2, the plants will grow better instead of
dying during global warming, right?
Some scientists don't think it will help plants. If the temperature increases, and the
precipitation increases then the rain will evaporate faster because of the heat. We would need an
increase of more than 7% just to have the same amount of water available for use as we do today.
There will also be a dramatic change in weather compared to the weather of today. There will be
periods of drought followed by periods of dramatic storms. A drought might occur when the plants
have just sprouted up from the ground. They won't be able to survive the drought. The same thing
will happen with storms. What if some wheat just got some nice full heads and a storm occurs? The
storm will break the heads off and ruin the wheat. Another problem with drought and storms is that
right after a drought the plants would be very weak. So when the storms come they will wash the
plants away. Along with the storms there will be floods. The floods will wash the topsoil off of the
fields into nearby creeks and rivers. The farmers won't have any topsoil to grow their plants on and
the state will have to spend a lot of money to dredge the topsoil from the creeks and rivers.
14. In the desert there are places called fringe lands. Fringe lands are strips of land that
are like a desert when it is very hot, but can grow things when there is enough rain.
When global warming occurs there will be no fringe lands, therefore making the
deserts larger.
Another problem with an increase in CO2 is that certain plants need certain
temperatures in order to grow. For example: Florida produces a large number of
oranges, when global warming occurs, what will orange farmers do? Florida is near
the equator, and is already very hot, so when global warming occurs it will be even
hotter. The oranges won't be able to grow very well. The only way for the farmers to
grow oranges is to move them further and further north. How will they do that? They
can't sell all their land, equipment, and homes, then buy land north of Georgia, can
they? No, because then those other states would become overpopulated. There would
be too many cars, people, and CO2.
So, what is your opinion of global warming's effect on agriculture? Do you think it
will help or hurt? Destroy or create? Again, some scientists think it will help, others
think it will hurt. Overall, global warming will effect agriculture very much.

16. Plains
The plains will have a lot
more fires than expected
because of
global warming. Global
Warming will add extra heat
to that region,
in addition to the heat they
already have there.
17. Coastal:-
The coastal regions will flood
because of all the extra rain.
This will cause many
inhabitants to leave their homes and flee.
18. Polar:-
A large portion of the Polar Ice Cap
might melt making sea level
rise 16-20 feet. A rise of 20 feet
in the sea level could cover most
of the state of Florida.
19. Forests
Some forests will dry up and become
deserts by the middle of this new
century. Also because of the increase
in thunderstorms there could be more
forest fires because of the lightning
and the dry wood from the trees.
20. Mountains
The snow covered mountain
peaks will probably melt causing
floods and very dangerous
mudslides.
21. Deserts
Most deserts will become much hotter
than they usually are making it much
harder to cross than it is today.
22. Fringe:-
A fringe land, which is the
fertile area in between a
desert, such as an oasis,
will probably dry up and
become part of the desert
and no longer be fertile
