CHAPTER 1: INTRODUCTION

Are you facing many terrible natural disasters in your country? I'm sure you are, because my own country is also enduring that So, do you know that natural phenomenon which seems to be created solely by Mother Nature but is actually influenced by human

actions? Humans are the cause of environmental pollution, indirectly leading to global warming, which in turn results in an increasing number of natural disasters

Over the past century, the Earth's surface temperature has increased by about 0.7°C Along with this, especially in the second half of the 20th century, the

concentration of CO2 in the atmosphere has risen rapidly This CO2 is produced by

human activities such as burning fossil fuels, deforestation, etc This raises awareness of the causal relationship between the increase in CO2 concentration and global warming

Global temperatures could rise from 1.1°C to 6.4°C in the 21st century;

assessments indicate that heatwaves, extreme heat, and heavy rainfall will occur more frequently with over 90% accuracy, and many regions will experience droughts, tropical storms, and extremely high sea levels with over 66% accuracy; CO2 emissions from the past and future will continue to cause the Earth to warm and sea levels to rise for more than a millennium to come

Global warming causes many terrible natural disasters, having a widespread impact on the environment, society, and the economy Global warming causes ice to melt

at the poles and glaciers, leading to a rise in sea levels This can result in flooding in

coastal areas and small islands Global warming causes climate change, increasing the

frequency and intensity of extreme weather events such as storms, floods, droughts, and heatwaves Ecosystems, such as forests, coral reefs, and grasslands, are being affected Some species of animals and plants may not adapt quickly enough to environmental changes, leading to the risk of extinction Global warming can increase the risk of heat-

related illnesses, such as heat stroke, and enhance the spread of insect-borne infectious

diseases, such as malaria and dengue fever

Recently, we have had to endure the effects of the super typhoon named Yagi

Yagi is a storm that has set many records, likely being the strongest storm in the world in

terms of wind speed in 2024 It brought heavy rain and whirlwinds that caused landslides

in many places Floods swept away crops, homes, and belongings of many families Many people also lost their lives after the storm due to not evacuating in time It is truly

heartbreaking to witness the devastation caused by nature

In short, this is a very big, urgent and important topic It directly affects the global economy, biodiversity and human life

CHAPTER 2: CONTENT

I What is global warming?

Global warming refers to the long-term increase in Earth's average surface

temperature due to human activities This phenomenon is a key component of climate change and is primarily driven by the accumulation of greenhouse gases in the atmosphere, such as carbon dioxide (CO2), methane (CH4), and nitrous oxide (N20)

These gases trap heat from the sun, preventing it from escaping into space, which leads to a "greenhouse effect” that warms the planet

ll | The cause of global warming

The primary cause of global warming is the increase in greenhouse gases in the Earth's atmosphere due to human activities Here’s a breakdown of the main

contributors:

2.1 Burning fossil fuels

Burning fossil fuel such as coal, oil, and natural gas releases energy that has been stored

in these materials for millions of years This process powers a significant portion of the world's electricity, heating, and transportation However, it also has several notable downsides:

Greenhouse Gas Emissions: Burning fossil fuels releases carbon dioxide (CO2)

and other greenhouse gases into the atmosphere These gases trap heat and

contribute to global warming and climate change

Air Pollution: The combustion process emits pollutants like sulfur dioxide (SOz), nitrogen oxides (NOx), and particulate matter These pollutants can lead to respiratory problems, cardiovascular diseases, and environmental damage And this is also the reason for the phenomenon of global warming

Environmental Degradation: Extracting fossil fuels often involves significant environmental disruption, including habitat destruction, water contamination, and soil degradation

Finite Resources: Fossil fuels are non-renewable resources, meaning they will

eventually run out This makes reliance on them unsustainable in the long term The shift towards renewable energy sources, such as wind, solar, and hydro power, aims

to reduce these negative impacts by providing cleaner, more sustainable alternatives

2.2 Deforestation

Refers to the large-scale removal or clearing of forests, which can occur through logging,

agricultural expansion, infrastructure development, and other human activities This practice has several significant and interrelated impacts:

Loss of Biodiversity: Forests are home to a vast number of plant and animal species When forests are destroyed, many species lose their habitats, which can lead to extinction and a decline in biodiversity

Climate Change: Forests play a crucial role in regulating the Earth's climate by

absorbing carbon dioxide (COz) from the atmosphere Deforestation reduces this

carbon sink capactty, confributing to higher atmospheric CO: levels and

exacerbating global warming

- Disruption of Water Cycles: Trees and forests influence local and global water cycles by regulating precipitation and groundwater levels Deforestation can lead

to changes in rainfall patterns, reduced water availability, and increased risk of droughts

¢ Soil Erosion: Trees and plant roots help to stabilize the soil When forests are cleared, the soil can become loose and prone to erosion, which can lead to reduced soil fertility and sedimentation in rivers and streams

- Impact on Indigenous Communities: Many indigenous and local communities depend on forests for their livelihoods, culture, and sustenance Deforestation can displace these communities and undermine their traditional ways of life

Efforts to combat deforestation include promoting sustainable land management

practices, enforcing environmental regulations, reforestation (planting trees in deforested areas), and supporting initiatives that protect and conserve existing forests

2.3 Industrial processes

Involve the methods and technologies used to manufacture goods and services on a large scale These processes can vary widely depending on the industry and the products being produced, but they generally include a range of activities from raw material extraction to final product assembly Here’s a breakdown of some key aspects and impacts of

industrial processes:

- Key Aspects of Industrial Processes:

1 Raw Material Extraction: Many industrial processes start with the extraction of raw materials, such as mining for metals or drilling for oil This phase can have

significant environmental and social impacts.

2 Manufacturing and Production: This involves transforming raw materials into finished products through various methods, including chemical reactions, mechanical processing, and assembly For instance, the production of steel involves melting iron ore

in a blast furnace

3 Energy Consumption: Industrial processes often require large amounts of energy, typically from fossil fuels, which can contribute to greenhouse gas emissions and climate

change

4 Waste Management: Industrial activities produce waste products, including

emissions, effluents, and solid waste Effective waste management is crucial to minimize

environmental impact and comply with regulations

5 Quality Control and Maintenance: Ensuring that products meet quality standards and maintaining equipment to prevent breakdowns are integral parts of the manufacturing

- Resource Depletion: Extracting and using natural resources can lead to resource

depletion and environmental degradation

2 Climate Change: The energy-intensive nature of many industrial processes

contributes to global warming through the emission of CO2 and other greenhouse gases

3 Health and Safety: Industrial activities can pose health risks to workers and nearby

communities, including exposure to toxic substances, noise pollution, and accidents

4 Economic and Social Impact:

- Job Creation: Industrial processes can create jobs and contribute to economic growth, but they can also lead to job displacement and require significant investment

- Community Impact: Industrial development can affect local communities through changes in land use, increased traffic, and potential impacts on local infrastructure and services

Overall, balancing industrial activity with environmental and social responsibility is key

to achieving sustainable development

2.4 Agricultural practices

Refer to the various methods and techniques used in farming and food production These practices can significantly impact the environment, economy, and society Here’s an overview of key agricultural practices, their impacts, and trends towards sustainability:

« Key Agricultural Practices:

2 Livestock Farming:

- Intensive Farming : High-density animal farming with significant use of

antibiotics and growth hormones Often associated with large -scale feedlots

- Pastoral Farming: Grazing animals on pastureland, which can be less intensive but

may require large areas of land

3 Soil Management:

Tillage: Plowing and preparing the soil for planting Can lead to soil erosion and degradation if not managed properly

No-Till Farming: Minimizes soil disturbance by planting crops directly into the residue of previous crops Helps reduce erosion and improve soil health

Pest and Disease Control:

Chemical Control: Use of pesticides and herbicides to manage pests and diseases Can lead to resistance and environmental concerns

Integrated Pest Management (IPM): Combines biological, cultural, physical, and chemical tools to manage pests in an environmentally and economically

Greenhouse Gas Emissions: Agricultural practices, especially livestock farming, can produce significant amounts of methane (CHa) and nitrous oxide (N20),

contributing to global warming

Deforestation: Clearing land for agriculture, especially in tropical regions,

contributes to CO2 emissions and loss of carbon sinks

2.5 Energy production and consumption

Energy production and consumption are central to modern life, affecting almost every

aspect of society, from industrial activities to everyday living Understanding how energy

is produced, consumed, and its impacts is crucial for addressing environmental concerns

and developing sustainable practices

« Energy Production: Energy production involves generating energy from various sources to meet demand Energy can be classified into renewable and non-

renewable sources Non-renewable energy has a negative impact on the

environment It is a cause of global warming

- Non-Renewable Energy Sources:

1 Fossil Fuels:

- Coal: Mined and burned to produce electricity and heat Major sources of CO2

emissions and air pollution

- Oil: Refined into gasoline, diesel, and other products Major contributor to transportation energy but has significant environmental impacts, including oil spills and air pollution

- Natural Gas: Used for electricity generation, heating, and as a feedstock in various industries Produces less CO2 than coal and oil but can contribute to methane

emissions

2 Nuclear Energy:

Nuclear Fission: Generates heat by splitting atomic nuclei (e.g., uranium or plutonium)

Produces large amounts of energy with low greenhouse gas emissions but poses

challenges related to radioactive waste management and nuclear safety

- Long-lasting waste: Nuclear energy produces highly toxic radioactive waste Toxic waste can leach into the soil, degrading soil quality, affecting agricultural

productivity and the survival of microorganisms Waste can seep into groundwater and rivers, lakes, causing water pollution, impacting aquatic life and human health

- Environmental pollution: Radioactive pollution can have long-term negative impacts on the environment, contributing to global warming It affects the flora

and fauna in the impacted areas, leading to a decline in biodiversity

- Water consumption: Nuclear power plants require a large amount of water for cooling, which can put stress on local water resources, especially in areas that are already water-scarce

- The risks from technical faults: The systems and equipment at nuclear power plants can malfunction, leading to leaks and contamination, affecting the

surrounding environment

2.6 Land use changes

e Energy Consumption: Energy consumption involves the use of energy for various purposes across different sectors:

1 Residential:

Heating and Cooling: Significant energy use in both cold and hot climates
