What You'll Learn
Increased transportation of goods
The increased transportation of goods that comes with globalization has a significant impact on pollution levels, particularly in third-world countries. The rise in global trade has led to a higher demand for freight transportation, which has a range of environmental consequences.
Firstly, the burning of fossil fuels by vehicles such as lorries and freight trucks releases carbon dioxide and other greenhouse gases into the atmosphere, contributing to global warming and climate change. Transportation is a major contributor to greenhouse gas emissions, with the sector's emissions having increased more in absolute terms than any other sector between 1990 and 2022. This has a particular impact on third-world countries, as the increased demand for transportation can lead to a greater use of diesel vehicles, which emit high levels of nitrogen oxides and particulate matter, causing air pollution and having detrimental effects on human health.
Secondly, the rise in air traffic caused by the increased transportation of goods has led to an increase in contrails, which are ice crystals formed from condensation around planes flying at high altitudes. While the exact impact of contrails is debated, they are believed to contribute to climate change by trapping heat, while also reflecting solar radiation. This can have an impact on global infrastructure and operations, with potential consequences for third-world countries that may lack the resources to adapt to these changes.
Thirdly, the increased transportation of goods can lead to the relocation of polluting activities to developing economies. For example, the shipping of electronic goods to countries with lower environmental regulations for disposal or recycling can result in the transfer of environmental externalities and negative health impacts to these regions. This can disproportionately affect third-world countries, as they may become dumping grounds for waste disposal, further contributing to pollution levels and health issues in these regions.
Lastly, the increased demand for transportation can lead to greater congestion on roads, particularly in urban areas. This congestion contributes to urban air pollution, affecting the health and well-being of residents. While the adoption of public transport systems can help mitigate this issue, the continued use of private cars and small passenger vehicles remains a significant source of transport-related air pollution.
Overall, the increased transportation of goods due to globalization has a range of environmental and health impacts, with third-world countries often bearing the brunt of these consequences.

Overfishing and overdependence on cash crops
Globalization has intensified international trade and consumption patterns, contributing to environmental issues such as overfishing and overdependence on cash crops in third-world countries.
Overfishing
Overfishing is a pressing environmental concern, with one-third of the world's fisheries pushed beyond their biological limits. This has resulted in a significant reduction in fish populations, impacting the marine environment and the livelihoods of those who depend on fishing. Developing countries, especially small island nations, are particularly vulnerable to the social and economic impacts of overfishing. As fish stocks decline, the food security and economies of these nations are threatened.
Advances in fishing technology and the growing capacity of fishing vessels have enabled commercial operations to catch more fish, exerting pressure on fish stocks and smaller-scale fishing communities. The demand for seafood continues to rise, driving overexploitation and further exacerbating the problem.
Overfishing also disrupts entire marine ecosystems. The decline in large shark species, for example, has led to an increase in their prey, such as rays, which then affects the populations of smaller fish and shellfish. Additionally, the unintentional capture and killing of non-target marine life, such as juvenile fish, corals, and other bottom-dwelling organisms, further impacts the health of the oceans.
Overdependence on Cash Crops
Globalization has led to economic specialization, with countries focusing on producing specific cash crops due to their high profitability. Examples of cash crops include rice, coffee, cocoa, and various fruits. While this specialization can boost productivity, it can also have negative environmental consequences, particularly in third-world countries.
Overdependence on cash crops can lead to loss of soil quality due to nutrient depletion, deforestation, soil erosion, increased landscape fragmentation, and loss of natural habitats. This habitat loss is especially prominent in tropical climates, where many cash crops are grown.
In summary, overfishing and overdependence on cash crops are significant environmental concerns resulting from globalization. These issues have far-reaching social, economic, and ecological implications, particularly in third-world countries, where they threaten food security, livelihoods, and ecological integrity.

Habitat loss and deforestation
While globalization has its benefits, it has had a predominantly negative impact on the environment, particularly in third-world countries. One of the main negative impacts is deforestation, which leads to habitat loss.
Globalization has accelerated the rate of deforestation, especially in tropical regions. Tropical forests are home to some of the most diverse ecosystems, with over half of the world's species residing in them. When these forests are destroyed, the habitats of many unique species are permanently altered, leading to a loss of biodiversity. This loss of biodiversity has been exacerbated by the introduction of invasive species through increased global travel and trade.
Deforestation has also contributed to climate change. Forests act as carbon sinks, absorbing carbon from the atmosphere. When forests are cut down, burned, or otherwise removed, they release carbon instead of absorbing it. In 2022, deforestation accounted for about 7% of global emissions, contributing to rising temperatures, changes in weather patterns, and an increased frequency of extreme weather events.
Agricultural expansion is the direct driver of almost 90% of deforestation. For example, oil palm harvesting accounted for 7% of global deforestation from 2000 to 2018. In Sumatra, rainforests on deep peatlands are being cleared, drained, and converted to pulp plantations, contributing to Indonesia's high greenhouse gas emissions.
Globalization has also led to economic specialization, where countries focus on their economic strengths while relying on imports for other goods. This has resulted in overdependence on cash crops, such as coffee, cacao, and fruits, contributing to habitat loss in tropical regions.
While deforestation appears to be declining in some countries, it remains high in others, including Brazil and the Democratic Republic of the Congo. Two-thirds of global forest cover loss occurs in the tropical and subtropical regions, where large clusters of deforestation fronts are destroying important ecosystem services.
Mitigation Efforts
There have been global and regional efforts to sustain forest ecosystems and address habitat loss and deforestation. The United Nations has set targets to promote the sustainable management of forests, halt deforestation, and restore degraded forests. The World Wildlife Fund (WWF) has also been working to strengthen certification standards for products made with materials from forests and ensure responsible management of agricultural lands to prevent encroachment on forests.

Industrial growth and manufacturing
Globalization has had a significant impact on industrial growth and manufacturing in third-world countries, leading to both positive and negative consequences for the environment. On the one hand, globalization has contributed to economic growth, improved standards of living, and increased international trade for these nations. On the other hand, it has also led to increased pollution and negative environmental impacts.
One of the primary effects of globalization is the opening up of new markets for businesses to sell their goods and source raw materials, labor, and components. This has led to a situation where finished products are travelling farther than ever before, resulting in increased emissions from transportation. The increased demand for raw materials and labour has also led to overexploitation of natural resources and substandard working conditions in developing countries.
For example, the garment industry in Bangladesh, which employs approximately four million people, pays its workers extremely low wages, even less than what a US worker earns in a day. This industry has also been associated with deplorable working conditions, as evidenced by the 2013 collapse of a textile factory building that killed over 1,100 workers.
Another consequence of globalization is the restructuring of economies, where countries move from resource extraction and processing to manufacturing and eventually to service-based economies. This transition can have both positive and negative environmental impacts, depending on whether sustainable practices are adopted. In the case of many third-world countries, the pressure to remain competitive in the global market has led to a focus on economic growth at the expense of the environment.
Furthermore, the benefits of globalization have not been evenly distributed, with some analysts arguing that it has negatively affected local and emerging economies. The relative instability of many African nations, for instance, has been cited as a reason why Africa has not benefited from globalization as much as other regions. Additionally, the development of ICT services, which can mitigate the adverse effects of globalization on the environment, has been uneven across different regions. While some countries in Sub-Saharan Africa have made significant investments in this sector, the lack of understanding of how latest technologies interact with essential factors for emerging countries has hindered their ability to fully utilize ICT to reduce negative environmental impacts.

Greenhouse gas emissions
Globalization has had a predominantly negative impact on the environment, with third-world countries suffering from the resulting pollution. The increased flow of goods, services, capital, people, and ideas across international boundaries has led to a rise in greenhouse gas emissions, with a more pronounced effect in high-income countries.
One of the main consequences of globalization is that it opens up new markets for businesses to sell their goods and source labor, raw materials, and components. This means that finished products are traveling farther than ever before, often halfway around the globe. The increased transportation of goods has led to increased fuel consumption and a greater level of greenhouse gas emissions. According to a report by the International Transport Forum, CO2 emissions from transport will increase by 16% by 2050, contributing to pollution, climate change, and ocean acidification. These emissions have a significant impact on biodiversity and the environment, with people in some areas suffering from limited access to water, which may be polluted and endanger their health.
Globalization has also led to economic specialization, with nations and geographical regions focusing on their economic strengths. This has resulted in some countries becoming major producers of energy commodities such as oil, natural gas, and timber. The burning of these fossil fuels for energy has led to increased greenhouse gas emissions, contributing to global warming and climate change. Additionally, economic specialization has led to habitat loss, deforestation, and natural resource overuse. For example, illegal deforestation in Brazil for cattle ranching and overfishing in Southeast Asia have contributed to reduced fish populations and oceanic pollution.
The growth of manufacturing due to globalization has also led to widespread air pollution, with poor air quality causing respiratory problems for people, especially vulnerable groups such as children, the elderly, and those with medical conditions. Soil quality has also been impacted by pollution, leading to contaminated crops and health issues for those who consume them.
While globalization has brought about many positive changes, such as improved quality of life in developing nations, increased international trade, and reduced international aggression, it has also had a detrimental impact on the environment, particularly in third-world countries. The increase in greenhouse gas emissions due to globalization has contributed to climate change, ocean acidification, and a loss of biodiversity, affecting both human and animal habitats and livelihoods.
