Answer: The "three Ps" in environmental health refer to pollution, population, and poverty.
Step-by-step explanation:
- Pollution and poverty: Poverty can contribute to environmental pollution, as people living in poverty may not have the resources to properly dispose of waste or to access clean water and air. This can lead to pollution and other environmental hazards that can have negative effects on health. Conversely, pollution can exacerbate poverty by damaging crops, fisheries, and other natural resources that are important for livelihoods.
- Population and pollution: As populations grow, there can be increased demand for resources such as energy, food, and water. This can lead to increased pollution and environmental degradation if these resources are not managed sustainably. For example, increasing demand for energy can lead to greater use of fossil fuels, which contribute to air and water pollution.
- Poverty and population: Poverty can contribute to high population growth rates, as families may have more children in order to increase their income and support in old age. This can lead to greater pressure on resources and the environment, particularly in areas where resources are already scarce. Conversely, high population growth rates can exacerbate poverty by putting pressure on resources and limiting economic opportunities.
