Natural capital refers to the world's stock of natural resources, including geology, soils, air, water, and all living organisms, which provide ecosystem services essential for human survival and economic activity. Examples of natural capital include forests, mineral deposits, freshwater supplies, and biodiversity. These resources underpin economic development, human well-being, and the sustainability of life on Earth. Recognizing natural capital is crucial because it highlights the need to preserve these resources amid growing environmental challenges.

Currently, humanity faces several significant environmental problems. Climate change is perhaps the most pressing, driven by greenhouse gas emissions, leading to temperature rises, sea-level increase, and extreme weather events. Pollution, both air and water, harms ecosystems and human health, with sources ranging from industrial emissions to plastic waste. Deforestation results in habitat loss, reduced biodiversity, and contributes to climate change. Additionally, overpopulation strains resources, leading to resource depletion, soil erosion, and loss of biodiversity. Addressing these interconnected environmental challenges requires integrated strategies for sustainable development.

The wealth gap refers to the unequal distribution of wealth among individuals and groups within societies or between countries. It highlights disparities where a small percentage of the population controls a substantial share of resources and wealth, while others live in poverty. The wealth gap can lead to social instability, reduced access to essential services, and hindered economic growth. Both economic policies and social initiatives are necessary to reduce this gap and promote equitable development.

Recycling and reuse are vital strategies in waste management and resource conservation. Recycling involves processing used materials into new products, thus reducing raw material extraction and energy consumption. Examples include recycling paper, plastics, glass, and metals. Reuse, on the other hand, extends the life cycle of products, such as using containers multiple times or repurposing old furniture. These practices help reduce waste, lower environmental impact, and save money, contributing to ecological sustainability.

Sustainability is the concept of meeting present needs without compromising the ability of future generations to meet their own needs. It involves balancing economic growth, environmental protection, and social equity. Sustainable practices include renewable energy adoption, conserving water, reducing emissions, and protecting biodiversity. The goal is to create resilient ecosystems and societies that can thrive over the long term without depleting natural resources or causing ecological damage.

Economic growth is frequently measured by Gross Domestic Product (GDP) and Gross National Product (GNP). GDP calculates the total value of goods and services produced within a country’s borders over a specific period, regardless of who owns the resources. GNP, however, includes the income earned by a country's residents abroad and excludes income earned by foreign residents within the country. Both metrics gauge economic performance, but GNP provides a broader perspective on the economic strength of citizens and companies associated with a nation.

Developed countries, such as the United States, Japan, and Germany, are characterized by high income levels, advanced technological infrastructure, diversified economies, and better healthcare and education systems. In contrast, developing countries like India, Nigeria, and Bangladesh typically have lower income levels, less industrialization, limited access to healthcare, and growing urban populations experiencing economic and social transitions. These differences influence economic opportunities, environmental impacts, and social development.

Pollution refers to the introduction of harmful substances or energy into the environment, causing adverse effects on ecosystems and human health. Common types include air pollution from vehicle emissions and industrial processes, water pollution from sewage and chemical runoff, and soil contamination. These pollutants originate from point sources, with identifiable locations such as factories, or non-point sources like agricultural runoff, which are diffuse and harder to control.

Point source pollution comes from a single, identifiable origin, such as a smokestack or wastewater pipe. Non-point source pollution is diffuse, originating from multiple sources over a large area, such as runoff from agricultural fields or urban landscapes. For example, factory discharges into a river exemplify point source pollution, while runoff from farmland carrying pesticides and fertilizers exemplifies non-point source pollution.

Factors that make pollution harmful include the toxicity of pollutants, their persistence in the environment, bioaccumulation, and the exposure duration. Toxic chemicals like heavy metals can cause acute or chronic health problems. Persistent pollutants, such as DDT or plastics, remain in the environment for decades, accumulating in organisms and disrupting ecosystems. The timing and level of exposure further influence the severity of health and environmental impacts.

Persistence in environmental terms refers to the duration a pollutant remains active in the environment without decomposing. Examples include plastic debris, which can last for hundreds of years, and certain pesticides like DDT, which degrade very slowly. These persistent pollutants pose long-term risks because they continue to affect ecosystems and organisms long after their initial release.

Resource types can be classified as renewable or non-renewable. Renewable resources, such as solar energy, wind, biomass, and freshwater, replenish naturally and can be sustained over time if used responsibly. Non-renewable resources, including coal, oil, natural gas, and minerals, form over geological timescales and are finite; once depleted, they cannot be replenished on a human timescale. Balanced resource management among these types is essential for sustainable development.
