Environmental conservation and action by Lorenz De JesusJosiah De Jesus
Environmental conservation involves protecting natural resources and biodiversity. It includes rebuilding ecosystems and ensuring all living things have a good quality of life. Conservationists understand that how we live reflects how we value nature. There are over 3,000 conservation organizations in the UK, with many volunteers helping with conservation work. Employers value vocational training in conservation skills like field identification that are important for monitoring biodiversity and climate change. Environmental pollution comes in many forms like air, water, land, noise, thermal, industrial, light and more. All can damage ecosystems and life if not addressed properly. Guidelines call for reducing environmental burdens at all stages from product development to use.

Industrial pollution and environmental degradation in India
Industrial activities contribute significantly to India's economic growth but also cause various types of pollution including noise, air, water, land, and environmental degradation. Industries are responsible for noise pollution from machinery and equipment. Air pollution from industries releases pollutants and particulate matter that harm humans and the environment. Water pollution occurs when industries discharge waste without treatment into rivers and groundwater. Land pollution results from improper waste disposal and use of pollutants in agriculture. Environmental degradation is the deterioration of resources like air, water, and soil and destruction of ecosystems from changes caused by human activity since the Industrial Revolution. Suggestions to reduce industrial freshwater pollution include minimizing water usage in processing, reusing
Global worming is caused by the greenhouse effect trapping heat in the atmosphere. The main causes are greenhouse gases like carbon dioxide and methane, as well as deforestation and air pollution from burning fossil fuels. Effects of global worming include rising sea levels, more extreme weather, and impacts on ecosystems and human health. To prevent further global worming, actions must be taken to reduce greenhouse gas emissions through sustainable energy practices and conservation efforts.

This presentation discusses environmental hazards such as ozone layer depletion, global warming, and biodiversity loss. It defines each hazard, describes their causes and effects. For ozone layer depletion, the main cause is manufactured chemicals like CFCs that deplete the ozone layer. For global warming, key causes are agriculture, deforestation, and burning fossil fuels. Biodiversity loss is caused by habitat destruction, climate change, pollution, and invasive species. The conclusion states that human activities can negatively impact the environment in hazardous ways.
Pollution is defined as the introduction of contaminants into the environment through human or natural actions, which can detrimentally impact living organisms. There are three main types of pollution caused by human activity: air pollution through hazardous substances in the atmosphere; water pollution from degrading the quality of large bodies of water; and land pollution resulting from industrial, commercial, domestic and agricultural activities on the Earth's surface.
This presentation discusses various types of pollution including air, water, and noise pollution. It defines pollution as the introduction of contaminants that cause adverse environmental changes. The main types of pollution are described along with their sources and effects. Air pollution is caused by factors such as vehicles, industry, and fires and can cause respiratory and cardiovascular issues. Water pollution from sources like industry, agriculture, and waste affects ecosystems and drinking water. Noise pollution from aircraft, vehicles, and construction can cause stress-related illnesses and hearing loss. While pollution may help plants grow and regulate temperature, its major disadvantages outweigh advantages as it endangers health, accelerates climate change, and harms the environment. The presentation concludes with a message about protecting the planet
The document presents on the topic of environment pollution and discusses its five main types: water pollution, air pollution, soil pollution, noise pollution, and light 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.
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.

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
Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
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.

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.

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.
ENVIRONMENT~ Renewable Energy Sources and their future prospects.tiwarimanvi3129
This presentation is for us to know that how our Environment need Attention for protection of our natural resources which are depleted day by day that's why we need to take time and shift our attention to renewable energy sources instead of non-renewable sources which are better and Eco-friendly for our environment. these renewable energy sources are so helpful for our planet and for every living organism which depends on environment.

4. WHAT IS ENVIRONMENT ?
Environment can be defined as the sum total of all the
living and non living elements and their effects on human
life.
TYPES OF ENVIRONNMENT:
1.Biotic ( includes all the living components)
2. Abiotic(includes all the non living components)
3.Cultural and socio economic (includes things made by
humans).
5. WHAT IS ENVIRONMENTAL
DEGRADATION ?
Environmental degradation can be simply defined as the degradation in the
quality of the nature by the deterioration of its resources and compromising
with the general health of the environment . This process can be entirely natural
in origin, or it can be a consequence of human activities .
Though the nature her self is responsible up to some extent but the
anthropogenic impact on the environment fast track its degradation .
Examples : Deforestation , soil erosion , water pollution, Air pollution, Depletion
of ozone layer .
6. TYPES OF ENVIRONMENTAL DEGRADATION
THERE ARE MAINLY THREE DIFFERENT TYPES OF
ENVIRONMMENTAL DEGRADATION :
1. LAND DEGRADATION
2. WATER DEGRADATION
3. ATMOSPHERIC DEGRADATION
7. LAND DEGRADATION
Land degradation can be defined as the temporary or permanent loss of
the productivity of the soil . The reason of land degradation are both
natural and anthropogenic .
Land degradation can also be defined as the decline in the overall health
of the soil .
Some Causes of Land Degradation :
1. Deforestation
2. soil erosion
3. over grazing of animals
4. poor waste management
5. over population
8. WATER DEGRADATION
Water pollution can be defined as the
alteration in the physical, chemical or
biological characteristics of water so that it
either becomes health hazard or unfit for
use .
Water pollution is the contamination of
water bodies , usually as a result of human
activities . Because of this anthropogenic
contaminants it becomes unsuitable for the
human use and also it becomes hazardous
to the marine life .
Causes of Water Degradation :
1. Thermal pollution
2. Washing of clothes in the water bodies
3. Disposal of wastes from the agricultural
lands. ETC
9. ATMOSPHERIC DEGRADATION
Atmospheric degradation can be defined as the
alteration of the atmospheric condition due to the
presence of unwanted substances known as
pollutants.
Atmospheric degradation is caused by air pollution
and it is the main contributor to the environmental
issues that is leading to global warming and
greenhouse gas emission .
The degradation of the atmosphere causes many
health related problems like respiratory diseases ,
skin diseases and it effects the overall health of the
environment .
Causes Of Atmospheric Degradation :
1. Smoke released from the vehicles and industries
2. Burning of fire wood
3. Mining operations
4. Construction and Agricultural activities .
10. CAUSES OF ENVIRONMENTAL
DEGRADATION
1.Deforestation 12. Natural hazards ( earthquake, land slide
cyclones , avalanches)
2.Overpopulation
3.Desertafication
4. Soil erosion
5. Air pollution
6. Water pollution
7. Improper waste management
8. Land fills
