1.
Who is the biggest polluter in the world?
Correct Answer
A. China
Explanation
China is considered the biggest polluter in the world due to its large population and rapid industrialization. The country's heavy reliance on coal for energy production, as well as its manufacturing sector, contribute significantly to air and water pollution. China's massive carbon emissions and high levels of pollutants have a significant impact on global climate change and environmental degradation. This has led to increasing international pressure on China to address its pollution issues and transition to cleaner energy sources.
2.
Who is the second biggest polluter in the world?
Correct Answer
D. The USA
Explanation
The USA is considered the second biggest polluter in the world due to its high levels of carbon dioxide emissions. The country's reliance on fossil fuels, particularly coal and oil, contributes significantly to its carbon footprint. Additionally, the USA has a large industrial sector that produces a significant amount of pollution. The country's size, population, and high levels of consumption also contribute to its status as a major polluter.
3.
Who is the biggest emitter of carbon dioxide in the world?
Correct Answer
A. China
Explanation
China is the biggest emitter of carbon dioxide in the world because of its large population and rapid industrialization. The country heavily relies on coal for energy production, which is a major source of carbon dioxide emissions. China's manufacturing sector is also a significant contributor to its high carbon emissions. Despite efforts to transition to cleaner energy sources and reduce pollution, China's carbon dioxide emissions remain the highest globally.
4.
What is the most threatening type of pollution in the world?
Correct Answer
D. Air pollution
Explanation
Air pollution is the most threatening type of pollution in the world because it has a wide range of harmful effects on human health and the environment. It is caused by the release of pollutants into the air from various sources such as industrial activities, transportation, and burning of fossil fuels. These pollutants include particulate matter, nitrogen oxides, sulfur dioxide, and volatile organic compounds, which can lead to respiratory diseases, cardiovascular problems, and even premature death. Additionally, air pollution contributes to climate change and damages ecosystems, making it a significant global concern.
5.
What represents 30% of all litter in the USA?
Correct Answer
D. Cigarette butts
Explanation
Cigarette butts represent 30% of all litter in the USA. This is because many people dispose of their cigarette butts improperly, throwing them on the ground instead of in a designated trash bin. As a result, cigarette butts accumulate and make up a significant portion of litter.
6.
How many water bottles are thrown away in the USA every year?
Correct Answer
C. 22 billion bags
7.
How many plastic bags are used every year in the US?
Correct Answer
A. 100 billion bags
Explanation
The correct answer is 100 billion bags. This number is a reflection of the high consumption of plastic bags in the US every year. The large population and widespread use of plastic bags in various industries contribute to this staggering figure. The excessive use of plastic bags has detrimental effects on the environment, including pollution and harm to wildlife. Therefore, efforts to reduce plastic bag usage and promote sustainable alternatives are crucial.
8.
What's the danger of polluting the oceans?
Correct Answer
C. The seabirds, marine mammals, and sea turtles can accidentally eat or become entangled in plastic debris
Explanation
The danger of polluting the oceans is that seabirds, marine mammals, and sea turtles can accidentally eat or become entangled in plastic debris. This can have severe consequences for their health and survival. Plastic debris can be mistaken for food by these animals, leading to ingestion and potential internal injuries or blockages. Additionally, they can become entangled in plastic debris, which can restrict their movement, cause injuries, or even result in drowning. Therefore, it is crucial to prevent ocean pollution to protect these vulnerable marine species.
9.
How many types of pollution are there?
Correct Answer
A. 7
Explanation
There are seven types of pollution, including air pollution, water pollution, soil pollution, noise pollution, thermal pollution, light pollution, and radioactive pollution. Each type of pollution has its own unique characteristics and sources, contributing to the overall degradation of the environment and human health.
10.
How many people are affected by pollution around the world?
Correct Answer
A. 100 million people
Explanation
There are approximately 100 million people affected by pollution around the world. This means that a significant number of individuals are experiencing the negative consequences of pollution, such as health issues and environmental degradation. The high number suggests that pollution is a global problem that requires urgent attention and action to protect human health and the planet.
