Natural resources and problems
Natural resources are materials found in nature that are valuable to humans. Due to population growth and industrialization, demand for natural resources is increasing while availability is limited, requiring proper management. Key natural resources include forests, water, minerals, food, and land. Forests help regulate climate and provide habitat but are threatened by deforestation. Water resources like rivers face issues like flooding, drought, overuse, and pollution. Mining and dams can negatively impact forests and water. Food production relies on agriculture and risks like modern farming practices, population growth, and land degradation including desertification. Sustainable management of natural resources is needed to meet current and future human needs.

Environment and natural resources
This document discusses several key issues relating to the environment and natural resources in global politics. It covers topics such as declining agriculture and forests, pollution problems like coastal pollution and the ozone hole, challenges in protecting global commons, differing responsibilities between developed and developing countries, pressures on common property resources, important environmental movements, resource geopolitics concerning items like oil and water, and rights of indigenous peoples.
Forest resources
Forests provide many commercial and ecological benefits but are being degraded and destroyed through overexploitation, deforestation, and development activities. Natural resources like timber, fuelwood, and land are extracted through logging, mining, and agriculture at unsustainable rates, damaging forest ecosystems, wildlife habitats, and tribal communities that depend on forests. Unless proper management and conservation efforts are implemented, one-third of the world's forests could be lost in the coming decades with significant negative environmental and economic consequences.
deforestation
Deforestation is the removal of forests to make room for human development. It has increased due to population growth, urbanization, and industrialization. Deforestation leads to soil erosion, flooding, loss of wildlife, increased carbon dioxide in the atmosphere, and other environmental issues. Pakistan has one of the highest deforestation rates in Asia due to unsustainable logging and lack of enforcement of forestry laws. Reforestation efforts and use of alternative energy are needed to address deforestation.

basic idea of natural resources
Natural resources can be categorized based on their origin as biotic or abiotic. They can also be categorized based on renewability as renewable or non-renewable. Biotic resources are living and able to reproduce, like plants and animals. Abiotic resources are non-living, like water, land, and minerals. Renewable resources can replenish themselves naturally or within human lifetimes, like water, sunlight, and wind. Non-renewable resources are limited and cannot renew, such as fossil fuels, minerals, and coal, which are considered exhaustible. Some resources are inexhaustible and present in unlimited amounts, like sunlight and water.

ESS Topic 3.2 - Resources as natural capital
Natural capital refers to natural resources that provide value to humans. Natural income is the growth or yield of natural capital over time, such as agricultural harvests, timber growth, or herd increases. For a resource to be used sustainably, only the natural income should be harvested, not the original stock, so that the resource is not depleted. The concept of sustainable development aims to meet current needs without compromising the environment and resources for future generations. However, defining and achieving sustainability can be debated, as views differ on how to balance environmental protection with economic interests.
Resources and natural capital
Natural capital refers to the stock of natural ecosystems that provide valuable goods and services. Forests and seas are examples that provide both tangible goods like timber and fish, as well as important services like flood protection and tourism. Resources are classified as renewable, replenishable, or non-renewable depending on their ability to regenerate. What is considered a resource changes over time based on economic and technological factors. Assessing the intrinsic value of the environment is challenging, but sustainability requires maintaining natural capital stocks to ensure their long-term ability to provide goods and services for future generations.

Flowering plants have evolved various adaptations for seed dispersal. The main methods are dispersal by wind, water, animals, and explosion. Seeds dispersed by wind have light structures like parachutes that allow them to travel far from the parent plant. Water dispersal occurs in plants like coconuts and water lilies whose seeds can travel for thousands of kilometers across oceans. Animal dispersal involves seeds passing through digestive tracts and being deposited far from the parent in waste. Explosive dispersal uses pods that burst open and shoot out seeds like in peas and beans.
Seed dispersal
Flowering plants have evolved various adaptations for seed dispersal to spread seeds far from the parent plant. The main methods of seed dispersal are by wind, by animals, by water, and by explosion. Seeds dispersed by wind are light with structures like hairs that aid wind transport. Seeds dispersed by animals pass through digestive tracts unharmed and are deposited far from the parent in feces. Seeds dispersed by water may survive ocean currents, while explosive plant pods forcibly eject seeds from the parent.
Natural resources by pooja
The document discusses different types of natural resources including renewable resources like air, water, forests that can replenish and non-renewable resources like fossil fuels that cannot. It emphasizes the need for conservation of resources through sustainable use and management to prevent depletion and ensure future availability, as human exploitation and overuse can degrade resources faster than they are renewed if limits are exceeded. The document provides examples of conservation measures like afforestation, waste reduction, and developing alternative energy sources to protect resources for future generations.
Resources
This document discusses natural resources in India. It begins by defining resources and describing different types of natural resources like biotic, abiotic, renewable and non-renewable resources. It then outlines India's major natural resource reserves like coal, iron ore, manganese, natural gas, limestone, thorium and minerals. India has significant oil and natural gas reserves located offshore and in states like Mumbai, Assam, Gujarat and Rajasthan. The document emphasizes the importance of sustainably managing resources and highlights India's potential in clean energy resources like solar and wind.
Energy Consideration: Foods and Energy Resources
This document discusses environmental considerations related to food and energy resources from the ocean. It covers several topics:
1) Food resources from the ocean are important for economies, communities, and recreation. Fisheries management must determine sustainable catch levels and allocate resources among users.
2) Mining and dredging on the ocean floor causes habitat destruction, though some activities like pearl diving are economically sustainable.
3) While industries like shipping, tourism, and energy extraction provide benefits, they also negatively impact ocean ecosystems through pollution, disturbance, and seabed damage if not properly regulated.
East Kolkata Wetland
The East Kolkata Wetlands were recognized in 2002 as a Ramsar site of international significance. They cover 125 square kilometers and include salt marshes, meadows, sewage farms, and settling ponds that are used to treat Kolkata's sewage through natural processes. However, the wetlands are now highly threatened due to urbanization putting the important ecosystem services they provide at risk.

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...
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.

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.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...
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.
