Environment management - exploitation & modification of natural resourcesAnish Gawande
Natural resources refer to all materials in nature that are required by humans for their well-beings. In other words, humans are totally dependent on natural resources for survival. For instance, they grow crops, catch fish, and rear livestock and poultry for food; they exploit fossil fuels for energy supply; they cut down timber, extract minerals, and collect water for various uses in industry, construction, and many aspects in daily life. Natural resources are customarily classified into renewable resources and non-renewable resources.
Renewable resources are resources that can be regenerated fairly rapidly through natural processes. Examples include oxygen, minerals in soil, wildlife, timber, fish, and fresh water. Theoretically, these resources are renewed naturally and are always available. However, if the rates of use exceed the rates of renewal, the resources will become depleted.
The documentary "Home" discusses how life originated on Earth 4 billion years ago, but humans have disrupted it at a massive scale in a very short period of time.

However, rapid population growth and industrialization have caused overuse of resources, pollution, deforestation, and climate change that threaten the planet's biodiversity and human lives. While problems like consumption, agriculture, fishing, and fossil fuel use have caused great harm, the documentary hopes to inspire individuals to make sustainable choices and work together to protect what remains of the natural world for future generations.
The document discusses launching an environmental awareness campaign. It defines key environmental terms like environment, natural environment, and interactions between physical, chemical, and biological components. It notes that our planet is facing problems like pollution, climate change, destruction of habitats, and species extinction. It provides some ideas to help save the environment like composting organic waste, reducing plastic use, and choosing products with less packaging.

NATURAL ENVIRONMENT,CATEGORIES OF RESOURCES,NATURAL RESOURCES,RENEWABLE AND NON-RENEWABLE,EXHAUSTIBLE , NON-EXHAUSTIBLE RESOURCES,HOW ENVIRONMENT IS CRUCIAL FOR US
Natural resources are materials provided by nature that are used by humans. They can be renewable, like water and forests, which can replenish, or non-renewable, like fossil fuels, which take millions of years to form. As populations grow, conservation of natural resources is important to ensure availability for future generations and maintain ecological balance. Various methods can be used to conserve different resources, like sustainable farming to conserve soil, limiting pollution and harvesting rainwater to conserve water, and protected areas and seed banks to conserve biodiversity. Legislation and public participation are also needed to effectively conserve natural resources.
The document describes natural resources and their environment. It defines natural resources as naturally occurring materials found in nature that humans use. Resources are grouped into seven categories: wildlife, air, soil, water, minerals, fossil fuels, and people. Resources are either renewable, like air and soil, which can replenish, or nonrenewable, like minerals and fossil fuels, which cannot be replaced once used up. All resources interact with and depend on each other in complex environmental relationships.

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.

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.
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.

NEEDOFSAVINGTHENATURE
Human activities are the main villain that harms
nature. Earlier, it was not evident the dangerous
effects of human exploitation on nature. Earth’s
natural resources are not infinite and they cannot be
replenished in a short period. The rapid increase in
urbanization has used most of the resources like trees,
minerals, fossil fuels, and water. Humans in their
quest for a comfortable living have been using the
resources of nature mindlessly. As a result, massive
deforestation, resultant environmental pollution,
wildlife destruction, and global warming are posing
great threats to the survival of living beings THUS ,
the need to save nature is very urgent because all
living beings are interdependent on nature. The
ecosystem will not work without nature.
