Vehicle exhaust, particularly from diesel engines, is a major contributor to air pollution in urban areas, releasing harmful pollutants such as particulate matter, nitrogen oxides, and hydrocarbons.

Sewage discharge, industrial waste, and agricultural runoff are all major sources of water pollution, releasing harmful contaminants, nutrients, and pathogens into water bodies.

Pollution can contaminate and degrade ecosystems, reducing their ability to provide resources such as clean air, water, and food. It can also increase the demand for resources, as efforts are made to clean up pollution and mitigate its effects. Additionally, pollution can disrupt the natural balance, leading to resource depletion.

Logging, particularly for commercial purposes, is a primary cause of deforestation, as forests are cleared to obtain timber and wood products.

Deforestation can reduce biodiversity, release carbon dioxide into the atmosphere, and cause soil erosion, all of which contribute to resource depletion.

Plastic waste, particularly single-use plastics, is a major source of marine pollution, as it accumulates in oceans and coastal areas, harming marine life and ecosystems.

Marine pollution can contaminate seafood, disrupt marine ecosystems, and reduce biodiversity, all of which can contribute to resource depletion.

Industrial waste, agricultural chemicals, and mining activities can all contribute to soil pollution, contaminating soil with heavy metals, chemicals, and other harmful substances.

Soil pollution can reduce soil fertility, contaminate groundwater, and affect plant growth, all of which can contribute to resource depletion.

Burning fossil fuels, such as coal, oil, and natural gas, is the primary cause of greenhouse gas emissions, releasing carbon dioxide and other greenhouse gases into the atmosphere.

Greenhouse gas emissions can cause climate change, affect weather patterns, and reduce agricultural productivity, all of which can contribute to resource depletion.

Agricultural activities, such as the use of fertilizers and pesticides, as well as livestock production, can contribute to air pollution in rural areas, releasing harmful pollutants into the atmosphere.

Air pollution can reduce visibility, affect human health, and damage crops and forests, all of which can contribute to resource depletion.

Agricultural runoff, containing fertilizers, pesticides, and animal waste, is a major contributor to water pollution in rural areas, contaminating water bodies and affecting aquatic ecosystems.

Water pollution can contaminate drinking water sources, affect aquatic ecosystems, and reduce water availability, all of which can contribute to resource depletion.
