Ground Green Week Quiz

Explanation
Switching out a 60W incandescent light bulb for its LED equivalent saves about 75 units of energy. LED bulbs are more energy-efficient than incandescent bulbs, using significantly less electricity to produce the same amount of light. This not only reduces energy consumption but also lowers electricity bills and decreases greenhouse gas emissions. Therefore, the correct answer is 75.

Explanation
In 2015, the U.S. consumed 19.4 million barrels' worth of petroleum products daily. This indicates the high demand for petroleum in the country during that year.

Explanation
In 1969, the Cuyahoga River in America caught fire, which led to the implementation of various pollution control measures. This incident gained significant attention and highlighted the severe pollution problem in the river. The fire on the Cuyahoga River became a symbol of the environmental degradation caused by industrial pollution and played a crucial role in the development of environmental protection laws and regulations in the United States.

Explanation
Catalytic converters became universally adopted following the Clear Air Act Extension of 1970. These devices are installed in the exhaust systems of vehicles and help reduce harmful emissions by converting pollutants into less harmful substances through chemical reactions. They play a crucial role in reducing air pollution and improving air quality.

Explanation
In 2009, the United States EPA declared greenhouse gases a threat to public health. This declaration was made in response to the growing scientific consensus that greenhouse gases, such as carbon dioxide, contribute to climate change and have negative impacts on human health. The EPA's decision allowed them to regulate and limit greenhouse gas emissions from various sources, such as power plants and vehicles, in order to protect public health and mitigate the effects of climate change.

Explanation
In 1996, the US EPA issued regulations requiring that home buyers and renters be informed of the presence of lead in paint. This is because lead-based paint was commonly used in homes built before 1978, and it can pose a serious health risk, especially to young children who may ingest or inhale lead dust. The regulations were implemented to ensure that people are aware of the potential hazards associated with lead-based paint and can take necessary precautions to protect themselves and their families.

Explanation
Motor vehicles like cars and trucks contribute to 50% of our air pollution. This means that half of the air pollution we experience is directly caused by emissions from these vehicles. This high percentage highlights the significant impact of motor vehicles on the environment and the need for sustainable transportation solutions to reduce pollution levels.

Explanation
Following the first Earth Day, several legislative actions were taken. The Clean Air Act Extension was passed to further regulate and reduce air pollution. The creation of the EPA (Environmental Protection Agency) occurred to consolidate and coordinate environmental regulations and enforcement. Additionally, the Clean Water Act was enacted to establish regulations and standards for water pollution control.

Explanation
The United States consumes the most energy in the world. This is due to its large population, high standard of living, and extensive industrial and transportation sectors. The United States has a highly developed economy that relies heavily on energy-intensive industries such as manufacturing, construction, and transportation. Additionally, the country has a high demand for residential and commercial energy consumption.

Explanation
The United States is the correct answer because it is the largest producer of energy in the world. It has a diverse energy portfolio, including oil, natural gas, coal, and renewable sources such as wind and solar power. The United States has a significant amount of domestic energy resources and a well-developed energy infrastructure, allowing it to produce and consume large amounts of energy. Additionally, the United States has a high level of energy consumption, which contributes to its position as the top energy producer globally.

Explanation
The Exxon Valdez oil spill occurred in Alaska. This spill was one of the largest environmental disasters in U.S. history, releasing millions of gallons of crude oil into the Prince William Sound. The incident had devastating effects on the local wildlife and ecosystems, causing long-term damage to the region.

Explanation
