Clean Coal? Myth or Reality.

The term "clean coal" is misleading because it minimizes the severe environmental damage caused by coal. Although some argue that technologies like carbon capture and storage (CCS) can make coal cleaner, coal remains a highly harmful energy source. Politicians and coal industry groups often use the term "clean coal" to suggest that coal can be part of the solution to climate change, but this idea doesn’t hold up when we examine the facts. Coal burning is one of the most significant contributors to greenhouse gas emissions worldwide. According to the Environmental Protection Agency (EPA), coal-fired power plants contribute nearly 40% of the United States’ carbon dioxide emissions (EPA, 2020). The burning of coal produces massive amounts of carbon dioxide (CO2), a greenhouse gas that contributes to global warming. Coal mining is also highly harmful to the environment. Methods like mountaintop removal mining destroys mountains, pollute rivers, and harm local ecosystems...

Activity 3.2.1 – Natural Resources Review

Image
  Natural resources are materials taken from the environment for energy, electricity, and materials (Jerome, 2017). They are divided into renewable and nonrenewable resources. Renewable resources, like water, wood, solar energy, and wind, can be replenished quickly, while nonrenewable resources, like fossil fuels and minerals, take millions of years to form and can’t be replenished easily. Scarcity occurs when resources are used faster than they can regenerate. For example, wood becomes scarce when trees are cut down faster than they grow back. Sustainability, recycling, and reusing help address scarcity. Sustainability involves using resources in a way that preserves them for future generations, such as conserving water. Recycling turns materials like plastic into new products, and reusing items, like a glass jar of tomato sauce can be used for homemade lotion or homemade pickles, which helps conserve resources. Synthetics, like plastic, replace natural resources but must be used ...

Activity 3.1 – Human Population

#1- More Developed- Region- East Asia Country- Japan Birth Rate- 6 Death Rate- 13 Population Growth Rate (rate of natural increase)- -0.7 Population (millions) mid-2024- 123.8 Infant Mortality Rate- 1.8 Total Fertility Rate- 1.2 Life Expectancy at Birth- Male 81, Female 87 GNI per Capita, PPP- $52,640 Medical Doctors per 10,000 Population Total- 26.1 Total Health Spending per Capita- $4,347 Explanation- Japan has a birth rate of 6 births per 1,000 people and a death rate of 13 per 1,000, leading to a declining population. The fertility rate is 1.2, which is insufficient for population replacement. Despite a low infant mortality rate of 1.8, the overall population growth rate is negative. Life expectancy is high, at 81 years for men and 87 years for women. There are 26.1 medical doctors per 10,000 in the population showing access to healthcare. Japan's GNI is $52,640, indicating an advanced economy and developed healthcare system.    #2- Less Developed- Region- South Asia Count...

Activity 2.2 cryosphere- Dana Glacier, Sierra Nevada

Dana Glacier, Sierra Nevada: Sation ric046 (USGS, 1883; T he Glacier Rephoto Project, 2013) Dana Glacier, Sierra Nevada: October 30, 2024          The Dana Glacier is located in the Sierra Nevada mountain range of California. Over the last century, the glacier has been shrinking due to the effects of global warming. The rapidly rising temperatures cause more rain than snow causing the glacier to melt slowly. This melting is intensified by the albedo effect, where exposed rock and dirt, darker than snow, absorb more sunlight, causing the glacier to melt even faster. The glacial meltwater that feeds into the rivers and streams diminishes as the glacier melts. This can lead to water shortages in populations that rely on freshwater resources like wildlife and human populations. This can also affect the agriculture in the region. This can affect agriculture because as the ice melts, the glacier can cause water pollution, changing the salinity and releasing ...
