Ecological succession & cycles of matter
Ecological succession describes how communities change over time through primary and secondary succession. Primary succession occurs in areas without soil, like new bare rock, where pioneer species establish and slowly transform the rock into soil over long periods. Secondary succession follows a disruption, like a forest fire, where the original community regrows through different stages. Mature communities tend to have greater biodiversity and are dominated by climax species well-adapted to the local environment. Cycles of matter, like carbon and nitrogen, are essential to life and involve exchanges between living things and their environment.

This document outlines several key factors that contribute to environmental degradation, including deforestation, waste, soil erosion, global warming, air pollution, water pollution, overpopulation, and nuclear accidents. It then discusses each of these factors in more detail. Specifically, it explains how deforestation removes trees, waste pollutes air and water, soil erosion is caused by various natural forces, global warming is driven by greenhouse gases, air pollution harms health and ecosystems, water pollution contaminates water bodies, overpopulation strains resources, and radiation accidents release harmful materials. Finally, it recommends several practices to promote a cleaner environment, such as afforestation, waste reduction, infrastructure improvements, proper waste disposal, reduced radiation, and lower pollution.
Patterns of environment variation in species
Variation in diversity patterns during succession in plants communities are due to the effects of selection on life history strategies under natural disturbances to plant community.
This presentation deals with the same.
Environmental problems
The document discusses various environmental problems caused by industrialization and human activities, as well as potential solutions. It outlines how the industrial revolution led to increased air, water and soil pollution from harmful substances. Five main types of pollution are described: garbage, chemicals, high-powered wastes, gases and noise. Other issues covered include resource depletion, exotic invasive species, and habitat destruction. The document concludes by advocating for conservation efforts, reducing waste through various strategies like reduce, reuse and recycle, protecting endangered species, and individual actions people can take to help the environment.
Eco System
This is a presentation about the ill-effects of unbalanced eco-system, their causes and possible remedies to make it a balanced Eco-System.
Eco system
An ecosystem is a community of living and non-living components that interact as a system. If there are more consumers than producers, decomposers will have less food, releasing fewer nutrients back into the environment. This leads to an unbalanced ecosystem. Habitat destruction by human activity is mainly for harvesting natural resources and urbanization, rendering habitats unable to support species. Pollution is the introduction of contaminants that cause adverse environmental changes in the form of chemical, noise, heat or light pollution from both natural and foreign sources. Global warming is the rise in average atmospheric and ocean temperatures since the late 19th century due to factors like increased greenhouse gas emissions.
Environment change
Natural disasters like drought, flood, and wildfire can significantly impact living organisms by altering their environments. Drought dries up habitats by depleting water sources like rivers and lakes and desiccating soil. Floods inundate land under heavy rain, washing away plants, soil, and destroying animal habitats. Wildfires fueled by drought conditions can ravage forests and other lands. These environmental changes caused by disasters threaten organisms by degrading or destroying the resources and shelter they rely on to survive.

Natural disasters
Natural disasters like floods, droughts, and diseases can negatively impact the environment and harm living things. Floods occur when heavy rain causes dry land to become covered in water, washing away soil and plants and causing animals to lose their habitats. Droughts happen when there is no rain for a long period, drying up water sources and soil and threatening living things that need water to survive. Droughts can also lead to wildfires that destroy habitats. Diseases from bacteria, mold, and mildew can spread among plants and potentially destroy large areas if left unchecked.

2. The largest polluters are often large-scale industrial operations that tend to cluster together.
3. Exposure to pollution can have varying effects from minor to severe, and sustained pollution usually impacts more people long-term than incidental pollution.
4. Access to clean water is vital for development but water scarcity impacts many people and threatens food supplies, economic growth, and international conflicts.
Forest and climate change a study how world By Mr Allah Dad Khan
Climate change is stressing forests through higher temperatures, altered precipitation, and more extreme weather. Forests play a major role in mitigating climate change by trapping carbon dioxide, but releasing carbon dioxide when destroyed. Different tree species will be impacted differently by climate change, with some benefiting and others declining. Changes in seasonal rhythms may damage interactions between plants and pollinators. Forest growth and productivity will be impacted by increases in temperature, changes in precipitation, and increases in carbon dioxide levels.

Natural Resources
This document discusses soil formation and properties. It covers:
1. Soil formation occurs through weathering of rocks, addition of organic matter, and formation of organo-mineral complexes. Weathering includes physical, chemical, and biological processes that break down rocks.
2. Physical properties of soil include texture, structure, density, porosity, consistency, temperature, color, and resistivity. Chemical properties include cation exchange capacity and pH.
3. Cation exchange capacity and pH are important as they influence nutrient availability and microbial activity. Soil properties impact functions like plant growth, water storage, and serving as a habitat.
Dealing with environmental concerns
The document discusses several factors that can lead to species extinction, including habitat loss, degradation of the environment, pollution, and climate change. It notes that habitat degradation is often caused by agriculture and urban expansion, which can limit resources and lead to extinction. Habitat loss occurs through destruction, fragmentation, or degradation, reducing the natural areas where organisms live. Environmental degradation is caused by depletion of resources from human and natural processes, such as pollution, deforestation, and global warming. Climate change is increasing occurrences of extreme weather and is driven by greenhouse gas emissions.
Unit 7 ch 11 s3 water pollution
This document discusses various types of water pollution including point source pollution from identifiable sources like factories, and non-point source pollution from diffuse sources like agricultural runoff. It outlines major pollutants like pathogens, nutrients, heavy metals, and plastic waste, and their sources. Groundwater pollution is difficult to remediate due to slow recharge rates and pollutants binding to underground materials. Most ocean pollution comes from non-point sources on land like runoff, carrying pollutants from cities and farms into coastal waters.
How do we use air & water
This document discusses different types of water resources and how water is treated and distributed for human use. It explains that there are two main types of water - fresh water found in rivers, lakes, glaciers etc. that is used for drinking, and salt water like oceans that is not used for drinking. It then describes some common ways water is transported and treated for human consumption, like through aqueducts, reservoirs, and wells, as well as the multi-step treatment process to clean and purify water. The document also briefly discusses natural and man-made water pollution and some ways to conserve important water and other resources.
How can changes in an environment affect living
Changes in the environment such as diseases like bacteria, mildew and mold or natural disasters like floods and droughts can significantly impact living organisms. Floods and droughts can destroy habitats by washing away soil and plants or drying up bodies of water, forcing some animals to migrate to find resources but causing others that cannot adapt or move to perish.
13 Chapter
The document discusses abiotic and biotic factors in the environment. It describes various abiotic factors like air, water, soil, sunlight, temperature and climate. It then explains concepts like the water cycle, nitrogen cycle, carbon cycle and energy flow through ecosystems. Food chains and food webs are defined as the transfer of energy and matter between producers, consumers and decomposers. Energy pyramids show that only about 10% of energy is transferred between trophic levels in a ecosystem.

How can changes in an environment affect living
There are many changes that can occur in an environment, such as natural disasters like droughts and floods, or diseases. These changes can affect living organisms in different ways - some are able to migrate to find a new habitat, others can adjust to survive, but some cannot adapt and end up dying. Common natural disasters that can degrade habitats include droughts, which dry rivers and soil, and floods, which can wash away plants and soil.
Human and environment interaction
Central Australia, also known as the Dead Heart, is uninhabitable by humans due to its dry nature and immense heat. Human settlement in Australia has been restricted to areas near water sources like river systems or the coast, as rainfall is too little inland. While Australia's population contributes a small percentage to global pollution, their concentration along the coasts isolates those living more inland. The environment has significantly shaped how and where humans live in Australia.
Natural Resources
Natural resources are materials that come from nature and can be used by humans. Examples include air, water, wood, oil, wind energy, natural gas, iron, and coal. Resources are either renewable, meaning they can replenish themselves, like forests and animals, or non-renewable, like fossil fuels which do not replenish quickly enough to be considered renewable. Natural resources face threats from overpopulation increasing demand, climate change altering environments, and pollution damaging the environment.

Environmental Changes and their Impact on Forest
The document discusses various types of environmental change and pollution including greenhouse gases, acid rain, water pollution, soil pollution, and their causes and effects. It provides details on how the greenhouse effect leads to global warming, how acid rain harms forests and plants. It also explains various sources of water pollution like sewage, industrial and agricultural waste, and oil spills. Sources of soil pollution discussed include pesticides, mining, coal ash, and treated sewage sludge. Health effects of soil pollution mentioned are effects on plant growth and risks of diseases from exposure to heavy metals and other contaminants.
Different types of pollution, it's causes and effects.
In this PowerPoint presentation I have explained about different types of pollution, its causes and effects.
Trees and their role in water management
Trees provide numerous environmental benefits by moderating climate, improving air quality, conserving water, and providing habitat for wildlife. They alter the environment through climate control by moderating the effects of sun, wind, and rain. Trees also improve air quality by filtering pollutants and absorbing carbon dioxide and other gases. Planting trees helps manage stormwater runoff and reduces flooding by intercepting rainfall and allowing more water to infiltrate into the soil.
Deforestation
Deforestation is the permanent destruction of forests to make land available for other uses. Forests play an important role in the water and carbon cycles by absorbing and releasing water and carbon slowly over time. Removing forests disrupts these cycles. Deforestation reduces the number of trees that store carbon, allowing more carbon dioxide to remain in the atmosphere and contribute to climate change. It also destroys habitats for many living things. Common causes of deforestation include converting land to agriculture, uncontrolled fires, overharvesting of fuelwood, mining, and climate change itself.
Forest and climate change a study how world By Mr Allah Dad Khan
Climate change is stressing forests through higher temperatures, altered precipitation, and more extreme weather. Forests play a major role in mitigating climate change by trapping carbon dioxide, but releasing carbon dioxide when destroyed. Different tree species will be impacted differently by climate change, with some benefiting and others declining. Changes in seasonal rhythms may damage plant-pollinator interactions that some insects depend on. Impacts on forests from climate change include altered growth processes and productivity over time due to shifts in carbon dioxide, temperature, and rainfall.
Final Project(BCA)- Estela Ria B. Espanilla BF
Deforestation is the permanent destruction of forests and woodlands for purposes like urban and construction development, growing crops, grazing land for livestock, and mining. This results in negative environmental impacts such as erosion, disruption of the water cycle, loss of biodiversity, flooding, and climate change from releasing stored carbon into the atmosphere. Individual actions like planting trees, reducing waste, and joining environmental groups can help prevent further deforestation.
consequences of deforeststation.pptx
Deforestation has led to several environmental consequences:
1) It disrupts the water cycle, reducing rainfall and causing drought.
2) It creates an imbalance in atmospheric gases as fewer plants absorb carbon dioxide.
3) It degrades soil quality as trees are no longer there to prevent erosion.
7yr 09 #22 Pollution
Pollution is environmental contamination from man-made waste that includes land, water, and air pollution. Major types of air pollution discussed are smog, acid rain, the greenhouse effect, and holes in the ozone layer, which can seriously impact health and the environment. Water pollution occurs when pollutants from human activities are discharged into water bodies without treatment, harming organisms. Preventing pollution requires individual actions like conserving water and properly disposing of chemicals and litter.

Green building notes
Microclimates are local atmospheric conditions that differ from the surrounding areas, sometimes substantially. They can exist on scales as small as a few square meters in a garden or as large as many square kilometers. Because climate involves spatial and temporal variation, distinct microclimates can form and persist within a larger region. Microclimates are common and can be found in most places.
Acid Rain And Its Effects On Forestry
Acid rain is caused by emissions of sulfur dioxide and nitrogen oxides reacting with water and other chemicals in the atmosphere to form acids. It occurs through both wet deposition as rain, snow or fog, and dry deposition as particles and gases. Wet deposition affects plants and animals through soil and water, while dry deposition builds up on surfaces until washed away. Acid rain damages trees by limiting nutrients, exposing them to toxins released from soil, and stripping nutrients from leaves. It has harmed over 30% of forests in Germany and 14% in Switzerland.
Modern enviorenmental problems
The document discusses several modern environmental problems including pollution, deforestation, desertification, habitat loss, and extinction of animals. It defines pollution as the accumulation of harmful substances in the air, water, and ground. Deforestation is described as the disappearance of forests caused by cutting down and burning trees, as well as pollution and fires. Desertification is defined as the transformation of landscapes into desert areas when the soil becomes dry and poor. Habitat loss occurs when natural areas are destroyed to make room for housing and industry.
Environmental Studies
Human activities like burning fossil fuels and deforestation are increasing greenhouse gases in the atmosphere and leading to global warming. Trees naturally absorb carbon dioxide from the air but deforestation is removing this natural carbon sink. Increased greenhouse gases trap more heat in the lower atmosphere, causing changes to weather patterns and threatening ecosystems. The human population has doubled in recent decades, increasing resource use and emissions without developing sustainable solutions.
Dhruv,Sakshit,Akshit
This document discusses key components of the environment including biotic factors like plants and animals, abiotic factors like air, water, and soil. It explains the relationships between these components through food chains and cycles. It also covers environmental issues like pollution, climate change, and the greenhouse effect. Maintaining a balance between oxygen and carbon dioxide is important for the planet. The document emphasizes protecting the environment to ensure sustainability of life.
3071 ppt -_natural_resources
The natural resources of Earth include air, water, soil, minerals and living organisms. Air is a mixture of gases that living organisms and combustion processes rely on. It also helps regulate Earth's climate. Water cycles through evaporation, condensation and precipitation in a continuous process. Soil is formed through weathering and supports plant life. These natural resources interact in biogeochemical cycles and sustain life on Earth. However, human activities like burning fossil fuels, industrial pollution and deforestation threaten these natural systems.
Pollution
This document discusses different types of pollution including air, water, sound, soil, radioactive, light, and thermal pollution. It describes the causes and effects of various pollutions and provides solutions to address pollution issues. The document focuses on pollution in India specifically, noting that population growth and vehicles have increased pollution levels. Both long-term effects like pulmonary disease and short-term effects are described. Solutions proposed include reducing greenhouse gases, afforestation, and increasing public awareness.
Global warming and Green house effect
The document discusses several topics related to greenhouse gases and global warming:
1) It explains what the greenhouse effect and global warming are, how greenhouse gases like carbon dioxide trap heat in the atmosphere and cause the planet to warm up over time.
2) It then covers the causes of global warming like greenhouse gas emissions from burning fossil fuels, deforestation, and industrial pollution, as well as consequences like climate change, rising sea levels, and endangered species.
3) Finally, it discusses solutions that can help mitigate global warming such as afforestation, transitioning to renewable energy, and reducing greenhouse gas emissions through conservation efforts.

Resources:
Resource refers to all the materials available in our environment which are technologically accessible, economically feasible and culturally sustainable and help us to satisfy our needs and wants. Resources can broadly be classified according to their availability — they are categorized into renewable and non-renewable resources. They can also be classified as actual and potential based on the level of development and use; based on origin they can be classified as biotic and abiotic, and based on their distribution, as ubiquitous and localised (private, community-owned, national and international resources). An item may become a resource with time and development of technology. The benefits of resource utilization may include increased wealth, proper functioning of a system, or enhanced well-being. From a human perspective, a natural resource is anything obtained from the environment to satisfy human needs and wants.[1] From a broader biological or ecological perspective, a resource satisfies the needs of a living organism (see biological resource).

Agn science project environment and geology part 2
- 1. Student Created! Teacher Approved! Introducing Environment and Geology Part 2
- 2. Deforestation Erosion Relationship of environment and energy
- 4. Deforestation Deforestation is considered to be one of the reasons for the global climate change. The trees act like filters, absorbing greenhouse gases and carbon emissions, and then produce oxygen. The less trees the more gases and carbon emissions will remain in our atmosphere. The forests also perpetuate the water cycle. If there arent that many forests, there wouldn’t be that much water vapor released into the atmosphere. Therefore our garden would not get as much rain as it needs for its growth.
- 5. EROSION
- 6. Erosion Erosion is the process of eroding by wind, and other natural sources.A type of erosion is soil erosion. Soil erosion is the removal of the topsoil faster than the soil processes can replace it. Soil erosion can be caused by rain, animals and natural causes.
- 8. Erosion The garden at Polo Park is vulnerable to the large amount of rain that Florida brings. This rain can cause the garden to flood and the plants to not grow properly. Strong winds are very popular in Wellington, these winds can blow away the soil in the garden beds. This can deprive the nutrients that the plants are supposed to receive.
- 9. RELATIONSHIPS OF ENVIORNMENT AND ENERGY
- 10. RELATIONSHIPS OF ENVIRONMENT AND ENERGY • Energy and environment is an interdisciplinary study aimed at natural science. • A major goal of energy and environment is to act as a forum for constructive and professional debate between scientists and technologists. • Another goal of environment and energy is to include the informed and environmentally concerned public and their organizations in debate.
