Positive Aspects:

1. 1. Medical Products: Petroleum is a raw material for the production of various medical products, including pharmaceuticals, medical devices, and synthetic materials used in healthcare.

1. 1. Energy Production: Oil is a major source of energy, and access to energy is crucial for healthcare facilities. Electricity generated from oil is often used to power hospitals and medical equipment.

Negative Aspects:

1. 1. Air and Water Pollution: Oil extraction, transportation, and refining processes can lead to air and water pollution. This pollution can have direct and indirect effects on human health, ranging from respiratory issues to contamination of drinking water.

1. 1. Climate Change: The burning of fossil fuels, including oil, contributes to climate change. Climate change can have wide-ranging impacts on human health, including the spread of infectious diseases, heat-related illnesses, and disruptions to food and water supplies.

1. 1. Accidents and Spills: Oil spills, such as those from oil tankers or offshore drilling, can have severe environmental and health consequences. Exposure to oil and the chemicals used to clean up spills can harm human health.

1. 1. Occupational Health: Workers in the oil and gas industry may be exposed to hazardous substances, leading to occupational health risks. This includes exposure to toxic chemicals, physical hazards, and the risk of accidents.

1. 1. Dependency on Non-Renewable Resources: Reliance on oil as a primary energy source contributes to the depletion of finite resources and can lead to geopolitical tensions. Transitioning to renewable energy sources is often seen as a way to mitigate these issues.
