Describe two impacts that come from obtaining coal and how these impacts have been affected by human population growth.

Obtaining coal has significant environmental and social impacts. Here are two examples of these impacts and how they have been affected by human population growth:
Air pollution: Coal mining and combustion release harmful pollutants into the air, such as sulfur dioxide, nitrogen oxides, and particulate matter. These pollutants can cause respiratory problems, heart disease, and other health issues, and also contribute to climate change. As the human population has grown and energy demand has increased, so has the use of coal, leading to a corresponding increase in air pollution. However, there has been increased awareness of the impacts of coal on air quality, and regulations and technology have been developed to reduce emissions from coal-fired power plants and other sources.
Habitat destruction: Coal mining can result in the destruction of habitats for plants and animals, particularly in areas with rich biodiversity. As human populations have grown, there has been increasing demand for resources, including coal, leading to more extensive mining activities and greater habitat destruction. However, there has also been growing recognition of the importance of preserving biodiversity and the need for sustainable development. This has led to efforts to mitigate the impacts of coal mining on habitats, such as reclamation and restoration programs, as well as a shift towards renewable energy sources that have less impact on biodiversity.
Overall, the impacts of obtaining coal have been affected by human population growth through increased demand and resource use, but also through increased awareness and efforts to mitigate these impacts.
Obtaining coal has several impacts on the environment and human society. Two major impacts are environmental degradation and climate change. These impacts have been significantly affected by human population growth.
1. Environmental degradation: Coal mining involves the removal of topsoil, vegetation, and rock layers to access coal deposits. This process leads to habitat destruction and soil erosion, negatively impacting ecosystems. Additionally, coal extraction can contaminate nearby water sources with heavy metals and other pollutants, further damaging local biodiversity. With the increase in human population, there is a higher demand for energy, resulting in more coal mining activities. As a consequence, the scale of environmental degradation caused by coal extraction has expanded, putting additional stress on ecosystems.
2. Climate change: Burning coal for electricity and industrial purposes produces greenhouse gas emissions, primarily carbon dioxide (CO2). CO2 is a major contributor to global warming and climate change. As the world's population has grown, the demand for energy produced from coal has increased, leading to higher CO2 emissions. This exacerbates the problem of climate change, as the more CO2 is released into the atmosphere, the more it intensifies the greenhouse effect, trapping heat and raising global temperatures. The impact of coal-related emissions on climate change has been magnified due to the growing energy needs of a larger human population.
In summary, the impacts of obtaining coal, such as environmental degradation and climate change, have been significantly influenced by human population growth. As the population increases, so does the demand for energy, leading to more coal mining and subsequent negative impacts on the environment and the climate.
