Air travel has both positive and negative environmental impacts. It is a major source of carbon dioxide emissions that contribute to global warming as fuel-burning airplanes have increased by 40% in the past decade. Developing countries like China and India that are experiencing over 100% growth in air travel will exacerbate this effect. However, air travel also allows for cultural exchange between populations as it connects people across the world, exposing them to new ways of life.
Earth and environment_day_presentation_group_a5lo0ody
Earth Day is celebrated to promote environmental protection and conservation. People work to protect human health from pollution and preserve plants. Environment Day encourages awareness of environmental issues as people recognize their role in protecting the planet for all. Some common problems that pollute the environment include auto oil leaks, paint brush washing, overflowing trash cans, and more. Solutions include reducing, reusing and recycling products and waste, as well as composting organic matter. People can also save energy by turning off lights and electronics when not in use, closing doors, and wearing warm clothing instead of overusing heating and cooling.
The children of GPS Nampally No-1 organized a rally to raise awareness about air pollution in their community. They created posters highlighting the health impacts of pollution from industries and vehicles. The children then went door-to-door in their neighborhood, explaining the problems caused by pollution to residents and encouraging actions like planting trees and reducing vehicle use. They also shared their knowledge with other children and felt their efforts could positively change some people's behaviors around pollution.
Petroleum is highly toxic and causes irreparable harm to the environment through oil spills and air pollution from its refining and combustion; the petroleum industry has degraded the planet through humanity's overuse of fossil fuels which are formed from ancient organic matter but release toxins when extracted and used. Good communication skills in English are important for engineers to succeed internationally, understand technical research and concepts, and write reports, as English has become the dominant language for technology, business, and aviation globally.
The document discusses various causes and effects of air pollution.

Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.

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.

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.
3. Children Need Clean Air
Every day, children walk past cars that are on.
When a car is on when it is parked, the car is idling.
There are many cars idling in parking lots, school zones,
parks and other places children go.
4. Most cars idle 16 minutes a day.
Idling is leaving the car on while parked.
School zones and parking lots are full of cars idling.
5. Idling Cars Cause Air Pollution
Air pollution damages the
eyes
nose
throat
heart
lungs
and causes diseases and sickness.
6. Children breathe 50 percent
more air per pound than adults.
Infants in strollers and children are the most at risk.
Air Pollution Can Permanently Damage
a Child’s Ability to Breathe
7. Car Exhaust Is Dangerous!

9. Idling Puts Dangerous, Toxic Chemicals
in the Air and Hurts Children’s Health
Asthma is the most common breathing problem
in children and causes the most school absences.
Breathing can be painful and difficult with
asthma, emphysema, COPD and lung diseases.
10. fumes.
About 4 million children develop asthma each year
because they breathe polluted air.
11. Air Pollution Is A Global Problem
2019 State of Global Air Report
Shortened life expectancy by 20 months on
average by breathing toxic air.
12. Idling Causes Air Pollution
Clean, Safe, Healthy, Good Air Does NOT Have
Dangerous Chemicals or PMs (Particulate Matter)
13. Eliminating idling cars in U.S. would remove as
much pollution as taking 5 million vehicles
off the roads.
14. 200,000 barrels of foreign oil
and 3.8 million gallons of fuel
are burned every day in the
United States because of idling.
15. Idling Produces CO2 and Climate Change
Burning 1 gallon of gas = 20 pounds of carbon dioxide
in the atmosphere.
CO2, carbon dioxide, is a greenhouse gas.
Greenhouse gases cause more and more heat over time.
27% of greenhouse gases, GHGs, in the U.S. are
are from transportation.
16. Each Year in the U.S. Idling Causes
30 million tons of CO2, carbon dioxide, to go into the air.
Every 100,000 idling drivers add 89,686 metric tons of CO2
into the air.
CO2 traps heat and contributes to
climate change and global warming.
19. The Artic glaciers are melting.
The oceans are getting warmer over time.
20. Let people know
• Modern cars don’t need to idle.
• Even on the coldest days, engines are ready in 30 seconds.
• Engine idling increases vehicle maintenance costs.
• Idling can shorten vehicle life.
21. Pollution adds up. You can help.
Let people know it makes a difference if they
turn OFF their car right after they park
and
wait to turn the engine ON until they are
actually driving, not checking their phones.
22. What can I do?
1. Share the facts.
