[Challenge:Future] challenge future: My Dream Job
The Great Barrier Reef in Australia has lost more than half of its coral meadows in the last 27 years due to pollution and global warming. A typical work day for a biologist studying coral reefs would involve early morning dives to collect samples and study the evolution or degradation of the seabed and its plant and animal life. The goal is to find solutions to reduce coral reef destruction and support more diverse underwater ecosystems. By 2022, organizations aim to protect the ocean which covers over 70% of the planet and is essential to life while addressing the threats posed by human pollution and evolution.
Powerpoint presentation notes
Deforestation is the permanent destruction of indigenous forests and woodlands for purposes like agriculture, cattle ranching, and logging. It has resulted in forests covering only 21% of the Earth's land surface today, down from four-fifths of their original area. Deforestation occurs through conversion of forest land to agricultural uses and cash crops, commercial logging, and felling trees for firewood. It has significant consequences like disrupting the carbon and water cycles and increasing CO2 emissions, potentially leading to climate change effects like warmer temperatures and drier conditions in some regions. It also contributes to problems like soil erosion, species extinction, and desertification.
Deforestation group work
The document discusses several human and natural causes and effects of deforestation. Some key human causes mentioned are expanding cities, lack of farming land, and cattle pastures. Deforestation releases large amounts of carbon dioxide and greenhouse gases stored in forests. It contributes significantly to climate change, and some countries' emissions are mostly due to deforestation. Deforestation also destroys natural habitats for many animals and can endanger species. Removing trees reduces the forest's ability to absorb carbon and participate in the water cycle.

Coral Reef Destruction Slideshow
Coral reefs are formed by colonies of tiny animals called polyps that have a symbiotic relationship with algae. Though they cover less than 1% of the ocean, coral reefs are home to 25% of marine species and have potential medical benefits. However, coral reefs are threatened by human activities such as pollution and dynamite fishing as well as climate change. When stressed, corals expel the algae living in their tissues, causing them to bleach and often die. Efforts to preserve coral reefs include cryopreservation and lab regeneration before returning corals to the ocean.

By contrast, Ukraine remains one of the most polluted countries due to industrial pollution in its east and the lingering effects of the Chernobyl disaster, while Germany has significantly reduced pollution since the 1990s through government investment and job
Life of bays supplement
This document provides background information to supplement a film called "Life of the Bays" about the habitats and ecosystems of Florida Bay, Biscayne Bay, and the Florida Keys. It describes the key habitats of coral reefs, sea grass communities, and mangrove forests. It explains how coral reefs are formed by coral polyps secreting calcium carbonate over many years. Sea grasses provide a nursery for fish and food for marine life. Mangroves stabilize the shoreline and create estuaries. These habitats are interdependent and sustain life in the bays.
Coral reefs and climate change
This presentation introduces two of the main threats that climate change poses to the survival of coral reefs: ocean acidification and bleaching events due to global warming.
The coral reef
Coral reefs are biologically rich ecosystems that support billions of people but are increasingly threatened by pollution, invasive species, disease, bleaching, and climate change. In response, the U.S. established the Coral Reef Task Force in 1998 to map, monitor, research the causes of degradation, and promote conservation of coral reefs. The Task Force and NOAA work to fulfill the goals of the Coral Reef Conservation Act of 2000 to protect these valuable ecosystems.

Deforestation
The document discusses deforestation, including its causes, effects, extent in India, and methods for control. It defines deforestation as the removal of forests and notes its main drivers are shifting agriculture, commercial logging, mining and dams. Deforestation leads to soil erosion, decreased rainfall, loss of biodiversity and plants used in medicine. India has lost over 3 million hectares since 1951 mainly due to population growth, development and dependency on forests. Reforestation efforts, legislation, wildlife sanctuaries and sustainable forest management can help control deforestation.
Forest Resources
Forests cover nearly half of the Philippines and provide many benefits such as preventing soil erosion, promoting rainfall, and maintaining air quality. However, forests are being destroyed through logging, farming, fires, and development. Conservation efforts include protected areas, reforestation, and laws against illegal logging. Forests are important to conserve due to their economic and environmental roles.
Ppt on forests
The document discusses national forests in four countries - Brazil, Indonesia, the United States, and India. Brazil's national forests aim to sustainably manage native forest resources and support research. Indonesia has extensive tropical forests covering over 98 million hectares that are being destroyed by logging and agriculture. The US has 155 national forests totaling over 188 million acres managed by the Forest Service. India has reversed deforestation, and its forest cover increased over the last 20 years according to the UN.
Forest resource
The document discusses forest resources and deforestation. It defines forests and their importance, listing their many uses from providing timber to supporting biodiversity. Forests help regulate climate and soil quality. However, large-scale depletion of forests is occurring due to agriculture, urbanization, mining, and fires. This causes issues like increased temperatures, soil erosion, and reduced rainfall. Conservation efforts include regulated cutting, reforestation, protected areas, and sustainable management. Deforestation is the large-scale removal of trees, reducing forest cover over 90%, with causes like desertification, habitat loss, and pollution. Controlling deforestation requires limiting human settlement, agriculture, mining, and overgrazing in forests.
Natural resources final ppt
Natural resources occur naturally and include materials like rocks, minerals, soil, rivers, and plants and animals. They satisfy human needs and can be used to create value. Humans are also a resource because through developing skills, they can develop other resources by adding value to physical materials. Any material from the earth that is used by living things and satisfies human needs is considered a natural resource. Resources can be biotic, like forests and animals, or abiotic, like air and water. Some resources are renewable, like sunlight, while others are non-renewable.
Forest Resources
Forests cover approximately 30% of the Earth's land and provide important resources but are also under threat. They store large amounts of carbon, harbor much of the world's biodiversity, and provide economic and social benefits. While deforestation rates have slowed somewhat globally, forests continue to be damaged by fires, diseases, and human activities like agriculture and development. Management of forests varies around the world, with some regions showing more sustainable practices than others. Protecting forests will help mitigate climate change and conserve ecosystems.
Natural resources
The document discusses the biosphere and its components - atmosphere, hydrosphere, and lithosphere. It describes the layers of the atmosphere and its role in regulating climate and temperature. It discusses air pollution and its effects. It explains how the hydrosphere in the form of oceans, rivers, etc. is essential for life. The lithosphere comprises the crust and upper mantle, and the breakdown of rocks over time forms soil. Biogeochemical cycles such as the water, nitrogen, carbon, and oxygen cycles are also summarized.

Ecuador is affected by both desertification and erosion, with almost 50% of the country susceptible to erosion and desertification affecting much of the western side. Erosion can be avoided by using land according to its capability, protecting the surface cover, controlling runoff, planting grass and ground cover, never leaving gardens bare and exposed, ensuring adequate drainage and water collection systems, adopting small pieces of land outside property, and creating awareness among children and young adults.
Cause and effect of erosion
Erosion gradually wears away soil and sand through water and wind. This document summarizes a science fair project that tests the effects of erosion on soil with and without grass. The experiment involves constructing boxes with soil on one side and soil with grass on the other. Different amounts of water are poured over each side to simulate rainfall, and the runoff is measured. The results show that the side with grass loses significantly less soil, supporting the hypothesis that grass roots help prevent erosion by holding the soil in place. In conclusion, the experiment provides evidence that vegetation can help slow the natural process of erosion.

Erosion, deposition, soil intro
This document discusses different types of erosion and deposition. It begins with definitions of erosion as the movement of sediment from one place to another, and deposition as dropped sediment. It then examines several specific types of erosion in more detail:
- Stream bank erosion occurs along streams and rivers due to running water and burrowing animals. Planting vegetation or using concrete mats can help control this type of erosion.
- Topsoil erosion involves the wearing away of the top layer of soil by water, wind, and gravity. Farming practices like no-till, contour plowing, and cover crops can prevent this type of erosion, which is important because topsoil contains nutrients and takes a long time to form.

Soil conservation involves protecting soil from natural and human-caused destruction through various methods. It is important because soil forms the basis for plant habitats and food sources. Soil takes a long time to form but is threatened by erosion. Key methods of soil conservation include contour plowing, terrace farming, strip farming, shelter belts, and afforestation. We need soil conservation to maintain fertile soil for growing food and supporting ecosystems.
Soil Erosion and Conservation
This document discusses soil erosion, its causes, effects, and methods for prevention. It covers:
- Natural and human-caused soil erosion, with the latter including overcropping, overgrazing, and deforestation.
- Problems from erosion like loss of topsoil and declining plant productivity.
- A case study on erosion and desertification in Africa's Sahel region exacerbated by climate change.
- Conservation methods like windbreaks, contour plowing, stubble planting, terraces, and stone walls.

Deforestation can be defined as the large-scale removal of trees from forests for human activities. It is a serious environmental concern as it can result in the loss of biodiversity, damage to natural habitats, disturbances in the water cycle, and soil erosion.
Landslides
A landslide is a type of mass movement where part of a slope fails and collapses downhill, carrying materials such as soil, trees, rocks, and buildings. Landslides can be caused by natural factors like heavy rain weakening the soil and slope, or by human activities like deforestation. They can cause severe damage through loss of life, destroyed structures, and devastated communities. When a landslide occurs, it is important to quickly alert others and evacuate the area as safety as possible in order to avoid injury. A tragic example is the 1963 landslide in Italy into the Vajont Dam reservoir, which caused a 250 meter wave that destroyed towns and killed over 2,000 people.
Desert reclamation techniques
This document discusses deserts and desertification. It defines deserts as arid regions with little vegetation that receive less than 10 inches of rainfall per year. There are different types of deserts classified by factors like rainfall, temperature, and location. Desertification is the process by which productive land becomes desert, threatening over 850 million people across more than 100 countries. Reclamation techniques to address desertification include controlling sand dunes, afforestation, and irrigation methods to enhance vegetation cover and protect soil.
Desert reclamation techniques
This document discusses deserts and desertification. It defines a desert as an arid region with little vegetation, and notes that deserts occupy 15-20% of the Earth's land area. It outlines different types of deserts and where they are typically found. Desertification is defined as deserts increasing in area and vegetation/soil depletion. The effects of desertification are described as reduced ability of the land to support life. Techniques to combat desertification include controlling sand dunes, afforestation, and irrigation. Examples from Mongolia and Algeria are provided. In conclusion, the document states that desert rehabilitation becomes more difficult and costly the longer degradation continues.
Erosion.
Erosion is the natural process by which rocks and soil are loosened and transported from one location to another by forces like water, wind, ice, and gravity. It can be accelerated by human activities like farming, mining, deforestation, and overgrazing. The main causes of erosion are water, wind, and ice. Water erosion occurs through processes like hydraulic action, solution, and abrasion in streams and rivers. Wind erosion transports soil particles through saltation, suspension, and creep. Glacial erosion uses processes like plucking and abrasion to erode and transport material. Control measures for erosion include mulching, crop rotation, terracing, barriers, and ridging to protect soil.
deforestation
Clearcutting is a logging practice where all trees in an area are cut down uniformly. It is economically profitable but also imposes environmental costs by removing habitat and contributing to issues like erosion, flooding, and climate change. While criticized for its impacts, proponents argue it can be used to create certain forest ecosystems and promote species that require sunlight. Long-term studies are important to understand how to best preserve forest resources.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

- 2. 1)What is erosion? Explain in detail how it happens? Erosion is the process by which the surface of the Earth gets worn down. Erosion can be caused by natural elements such as wind and glacial ice. Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity.
- 4. 2)Erosion problems in Madagascar. Find all the statistical information related to it. In madagascar there are many erosion.because the people cut down trees and farm and stay there 2 or three years an go then the erosion begin. Madagascar 30 years ago it was an island with many trees but now they are no. The erosion has extended three fourths of the forests
- 6. 3)Are there erosion problems in Ecuador? Where exactly?
- 8. 4)How can erosion be avoided? Research about the 5 main technics to fix the problem. Give examples. We can avoid erosion by using land according to its cability protecting the surface cover and controlling the runoff. o I investigate 5 ways to avoide erosion: Plant grass and ground cover in huge expansive gardens and on sport fields. 2) Never leave gardens bare and exposed. 3) Make shure that homes and buildings have an adequate draining and water collection systems. 4) Adopt a small pice of land outside your property as your own. 5) Create awareness among children and young adults.
