1.1 Introduction
Pollution is defined as the introduction of harmful substances or products into the environment, leading to adverse effects on human health, ecosystems, and the overall quality of life (World Health Organization, 2018). It manifests in various forms, including air pollution, water pollution, soil contamination, noise pollution, and plastic pollution, each contributing uniquely to environmental degradation and societal challenges (Ajayi, 2019). In contemporary society, pollution is primarily driven by human activities such as industrialization, urban expansion, deforestation, improper waste management, and the excessive use of fossil fuels (Oluwafemi & Abiola, 2021).
Industrial processes release toxic gases and chemical effluents into the air and water bodies, while vehicular emissions contribute significantly to air quality deterioration, particularly in urban centers. Agricultural practices, including the use of pesticides and fertilizers, result in soil and water pollution, affecting both human health and agricultural productivity (Adewumi, 2020).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Pollution has emerged as one of the most pressing environmental challenges affecting societies globally. According to Ajayi (2019), pollution is the release of harmful substances into the environment, which negatively affects human health, ecosystems, and the overall quality of life. It is reported that rapid industrialization, urbanization, and technological advancement have significantly contributed to the increased levels of environmental pollutants in modern society (Oluwafemi & Abiola, 2021).
According to Ajayi (2019), the Industrial Revolution marked a turning point in environmental degradation, as rapid industrial growth led to increased emissions of smoke, chemicals, and waste into the environment. It is reported that urban areas began experiencing severe air and water pollution due to inadequate waste management and the uncontrolled discharge of industrial effluents into rivers and streams (Oluwafemi & Abiola, 2021).
Several scholars have asserted that air pollution, water contamination, soil degradation, and noise pollution are the most prevalent forms of pollution affecting communities worldwide (Adewumi, 2020). Ajayi (2019) stated that industrial activities discharge toxic chemicals into rivers and air, causing severe health and environmental hazards. Similarly, Eze and Nwosu (2018) affirmed that vehicular emissions and the indiscriminate burning of fossil fuels significantly deteriorate air quality, particularly in urban areas, thereby exposing populations to respiratory and cardiovascular diseases.
Environmental scholars contend that improper waste disposal and the excessive use of chemical fertilizers in agriculture exacerbate soil and water pollution, reducing agricultural productivity and threatening food security (Chukwu, 2019). It is further reported that pollution is not only a public health concern but also imposes substantial economic costs on society, including medical expenses, reduced productivity, and environmental remediation efforts (Olusanya, 2020). On the other hand, inadequate enforcement of environmental laws and low public awareness have perpetuated the persistence of pollution-related problems in many developing countries. According to Oluwafemi and Abiola (2021), climate change, loss of biodiversity, and ecosystem disruption are among the broader consequences of continued pollution, affecting sustainable societal development. This study is set against the backdrop of these environmental and societal concerns, aiming to explore the causes and effects of pollution on society.
1.3 Statement of Problems
Investigation revealed that pollution is linked to a wide range of health issues, including respiratory diseases, cardiovascular disorders, and even certain forms of cancer, impacting the quality of life of individuals and communities (Adewumi, 2020). On the other hand, pollution is not only a public health concern but also an economic burden, as the costs associated with medical care, loss of productivity, and environmental remediation place a significant strain on national resources (Eze & Nwosu, 2018).
Additionally, societal awareness and policy enforcement are often inadequate, leading to the continued degradation of natural resources and environmental sustainability. The lack of proper education on environmental protection measures and weak regulatory frameworks exacerbate the problem, leaving communities vulnerable to the adverse effects of pollution (Chukwu, 2019).
Furthermore, the cumulative impact of pollution contributes to climate change, reduced biodiversity, and compromised food security, all of which have long-term implications for societal development (Olusanya, 2020). It is against this backdrop that this study seeks to explore the causes and effects of pollution on society.
1.4 Aim and Objectives of Study
The aim of this study is to investigate the effect of pollution on society, identify its primary causes, and evaluate its social, economic, and environmental impacts. To achieve this aim, the study has the following objectives:
- To evaluate the effectiveness of current policies and public awareness programs in mitigating pollution.
- To identify the major sources of pollution affecting communities in Nigeria.
- To examine the health implications of environmental pollution on society.
- To assess the socio-economic and environmental impacts of pollution.
- To propose recommendations for sustainable practices and policy interventions to reduce pollution.
