The document discusses two major rainforests - the Amazon and the Congo. It notes that the Amazon produces all the oxygen needed for the world and contains vast biodiversity, but it is currently suffering from fires, reduction in flora and fauna, and deaths of indigenous people due to climate change. The Congo forest covers over 200 million hectares and is home to many endangered species, maintaining 10-20% of the planet's carbon. However, deforestation is growing exponentially due to road construction, and the forest surface has halved in recent years. Rainforests are important as they produce oxygen to sustain life and help dispose of pollution, but cutting them down decreases oxygen and increases pollution.

Amazon rain forest
The document discusses the Amazon rainforest, including its importance, causes of deforestation, and consequences. The largest rainforest in the world, over half of it is located in Brazil and home to over 30 million people from 350 ethnic groups. It plays a key role in regulating oxygen and carbon cycles, producing 6% of the world's oxygen. Deforestation has increased over the last 50 years due to agriculture, cattle farming, and infrastructure development. This results in higher carbon dioxide levels and loss of biodiversity, threatening the planet. While organizations work to address it, illegal activities remain difficult to fully address.
Deforestation Power Point
Deforestation is the loss or degradation of forests due to natural or human causes such as agriculture, urbanization, mining, and unsustainable logging. It has significant environmental impacts including reducing biodiversity, increasing carbon dioxide emissions, and causing drier climates and soil erosion. Efforts to control deforestation include the Kyoto Protocol, REDD mechanisms to incentivize avoided deforestation, forest management practices, and reforestation programs.
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.

Natural resources are natural substances required by humans for different needs. They include metals, minerals, water, crops, forests, and rainforests. Natural resources such as oil, gas, coal, wood, wind, sunlight and waves can be used to produce energy and are called energy resources. Non-renewable energy sources like oil, natural gas and coal cannot be easily replaced as they take millions of years to form, whereas renewable resources such as wind power, solar power, and hydropower can be replaced and will not run out.
Presentation on mountain ecosystem
Mountain ecosystems are important because mountains are home to 10% of the world's population and cover 25% of the earth's land. They supply fresh water to half the world's population and are centers of biological diversity. However, mountain ecosystems face threats such as habitat loss, species loss, and impacts on mountain peoples from factors like deforestation, infrastructure development, agriculture, tourism, and climate change. To protect mountain ecosystems, recommendations include changing attitudes, establishing environmental taxes, education programs, research, and protected areas. Bangladesh's mountain ecosystems include the Chittagong Hill Tracts and Sylhet Division, and the government is taking steps like reforestation, awareness campaigns, and laws to promote conservation.
Deforestation
Deforestation involves the removal of forests and trees to convert the land to non-forest uses like agriculture. It occurs for many reasons such as using the wood for fuel or timber or clearing the land for livestock grazing or crop planting. Deforestation damages habitats and biodiversity by reducing forest cover and can contribute to aridity. It also affects the water cycle by decreasing the amount of water in the soil, groundwater, and atmosphere as trees are cut down.

Natural resources include living resources like forests and animals, and non-living resources like soil, land and water. They can be classified as renewable like forests, or non-renewable like minerals. Forests provide timber, fuel, habitat, regulate climate and water cycles. Deforestation due to shifting cultivation, grazing, agriculture and industry damages the environment by causing soil erosion, reducing biodiversity, and disrupting nutrient cycles. Water is essential for life and circulates through the hydrological cycle of evaporation, condensation, precipitation, and infiltration into groundwater aquifers or surface water bodies like rivers and lakes that are important for agriculture, industry, and domestic use.
Tropical forest (By: J.Q)
Tropical rainforests have high biodiversity and receive abundant rainfall. They regulate the Earth's climate by absorbing carbon dioxide and producing oxygen. Rainforests are found between the Tropics of Cancer and Capricorn and have warm temperatures year-round. They can be divided into four layers - emergent, upper canopy, lower canopy, and forest floor. While rainforests cover only a small portion of the Earth's surface, they are home to most of its plant and animal species. The largest threats to rainforests are deforestation through logging and mining activities, which degrade habitat and increase greenhouse gases.

Gem ppt-20-protect mangroves
Mangroves are coastal forests found in tropical and subtropical regions that provide important ecological benefits. They act as buffers between land and sea, protecting coastlines from erosion and storms. Mangroves are rich ecosystems that are home to diverse plant and animal life. However, around half of the world's mangroves have been lost, mainly due to conversion to shrimp farms and other coastal development. The document outlines the types of mangroves found in India and their importance, and suggests actions to better protect and restore these critical coastal ecosystems.
Topic
Rainforests provide habitat for many species of plants and animals, regulate the climate, prevent soil erosion, and are home to indigenous people. They store large amounts of water and carbon while their soils have few nutrients. Deforestation damages the land and threatens over half of the world's plant and animal species. Rainforests are an important source of medicines, foods, and industrial products.
Group No 1( Deforestation).pptx
Deforestation involves the removal of forests to make way for other land uses such as agriculture, ranching, or urban development. It occurs for several reasons including harvesting trees for fuel or building materials and clearing land for livestock grazing or crop cultivation. The main causes of deforestation are agricultural expansion, commercial logging, mining, and urbanization. Deforestation has significant environmental impacts such as releasing carbon into the atmosphere, reducing biodiversity, increasing soil erosion, and disrupting the water cycle. While it provides some short-term economic gains, deforestation reduces long-term economic productivity and ecosystem services. Efforts to control deforestation include monitoring with aerial photos or satellite imagery and sustainable forest management practices.
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.

Carbon footprint banchetti
A carbon footprint is defined as the total amount of greenhouse gases produced directly and indirectly to support human activities, usually expressed as tons of carbon dioxide equivalents. It measures the greenhouse gases an individual or organization is responsible for emitting in a given time period, such as a year. Greenhouse gases like carbon dioxide trap heat in the atmosphere and contribute to climate change effects like rising temperatures and melting glaciers. Carbon footprints have direct emissions from sources like fuel combustion and indirect emissions from processes like electricity production. Small changes like using public transportation instead of cars, reducing energy usage, switching to renewable energy, eating less meat, and recycling can help reduce individual carbon footprints.
Foodprint(1)
Food's carbon footprint, or foodprint, is defined as the greenhouse gas emissions produced during the entire lifecycle of food production and consumption. The document shows that meat, cheese and eggs have the highest carbon footprints, while fruits, vegetables, beans and nuts have much lower footprints. It includes a table comparing the greenhouse gas emissions in kilograms of CO2 equivalent and miles driven to produce 1 kilogram of different foods, with lamb and beef having the highest footprints. The document provides 10 nutrition tips for reducing one's carbon footprint such as eating less meat and dairy, wasting less food, using less plastic, and growing your own produce.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Rainforests
- 1. Kevin Michelini The Amazon • The Amazon is a geographic region of South America where the rainforest, called the Amazon forest, is located. • Also called the Earth’s green lung because of its size and importance, it constitutes more than half of the world’s tropical forests. • The Amazon forest is home to a vast biodiversity: • FLORA : it produces all the oxygen needed for the world and contains almost all the plants in the world. • FAUNA : contains almost all animal species in the world. The current situation of the Amazon forest • Unfortunately the Amazon is suffering the serious consequences of climate change. The fires have caused a drastic reduction in flora and fauna, and many indigenous people have also died as a result. • This drastic restriction of the forest has also led to an even greater increase in the greenhouse effect and the ozone hole.
- 2. The Congo • The Congo forest is an equatorial rainforest found in Central Africa. It occupies most of the Congo basin. • The forest has an area of over 200 million hectares and is home to around 10,000 species of tropical plants, and a large number of endangered animals, including the forest elephant, chimpanzees, bonobo and lowland and mountain gorillas. • The forest has great importance for maintaining the climate. It is estimated that it maintains between 10 and 20% of the planet's carbon • Deforestation in the Congo Basin is growing at an exponential rate also thanks to the continuous construction of roads and transport routes inside the rainforest. • In fact, in recent years the surface of the forest has halved due to the construction of roads The current situation of the rainforest in Congo
- 3. RAINFORESTS ARE VERY IMPORTANT FOR US • They are made of many trees and they are able to produce all the oxygen necessary to keep all the living species alive. • They are important because they help us to dispose of the pollution we produce. • Cutting down the rainforests has 2 consequences: decreases the oxygen that is produced in the world and increase pollution. • It is very easy to share information with the world at this time as just one click to show it to the whole world. • Rainforests have a central role because through photosynthesis they are able to live all the living species in the world
