The Ultimate Environment Quiz To Test Your Knowledge

All are fossil fuels which are neither ecofriendly nor renewable.

As the concentration of greenhouse gases grows, more heat is trapped in the atmosphere and less escapes back into space. This increase in trapped heat changes the climate and alters weather patterns.

Both natural and human factors contribute to the changes of the Earth's climate. According to the U.S. Geological Survey (USGS), the world’s volcanoes generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes comprise less than one percent of those generated by today’s human endeavors.

3% of the earth's water is fresh. 2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost. 0.5% of the earth's water is available fresh water.

China surpassed the USA in 2006/7.

Oil on ocean surfaces, which is called an oil spill, is harmful to many forms of aquatic life because it prevents sufficient amounts of sunlight from penetrating and also reduces the level of oxygen dissolved in seawater. Crude oil renders feathers and gills ineffective, so that birds and fish may die from direct contact with the oil itself.

Energy production is the largest source of global greenhouse gas emissions, contributing over 70% of the total emissions. This includes the burning of fossil fuels (coal, oil, and natural gas) for electricity and heat, which releases significant amounts of carbon dioxide (CO₂) and other greenhouse gases. Deforestation and agriculture are also major contributors, but their impact is smaller compared to energy production. Industrial processes release greenhouse gases as well, but again, the emissions from energy production surpass all other sectors, making it the leading contributor to climate change.

Oil provides the U.S. with about 39% of its energy.

Even if we stopped sending CO2 into the atmosphere, our past actions would still affect the planet for decades to come.

Greenhouse gases are gases in the Earth's atmosphere that trap heat. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. While oxygen is essential for life, it does not trap heat in the atmosphere like greenhouse gases do.

 Deforestation, the clearing of forests for agriculture, logging, or urban development, removes vegetation that holds soil in place. Without tree roots and plant cover, soil becomes more susceptible to erosion by wind and water. This leads to loss of fertile topsoil, decreased soil quality, and increased sedimentation in water bodies, impacting ecosystems and agriculture negatively.

To create just 1 kilogram of consumer goods, manufacturers create 5 kilograms of waste. This means that for every unit of consumer goods produced, there is a significant amount of waste generated. This waste could be in the form of byproducts, packaging materials, or other types of waste generated during the manufacturing process. The high ratio of waste to consumer goods highlights the environmental impact and inefficiency of the manufacturing process.

The correct answer is 6%. This suggests that rainforests have significantly decreased in coverage over time, from 14% to just 6% of the earth's land surface. This decline in rainforest coverage is a result of deforestation, climate change, and human activities such as logging and agriculture. The loss of rainforests is concerning because they are vital ecosystems that support a wide variety of plant and animal species, as well as provide important ecological services such as carbon sequestration and regulation of the water cycle.

This means that glass can be recycled an infinite amount of times.

After a thorough examination of the scientific evidence and careful consideration of public comments, in 2009 the U.S. Environmental Protection Agency (EPA) announced that greenhouse gases (GHGs) threaten the public health and welfare of the American people.

 Carbon dioxide is the most abundant greenhouse gas emitted by human activities such as burning fossil fuels and deforestation. It traps heat in the atmosphere, contributing significantly to global warming and climate change. While other gases like methane and nitrous oxide also contribute to the greenhouse effect, carbon dioxide is the primary driver due to its long-lasting presence in the atmosphere.

Volunteers for the International Coastal Cleanup removed nearly two million cigarettes and cigarette filters in their most recent effort to clear litter from the world's oceans.

During the 150 years of the industrial age, the atmospheric concentration of carbon dioxide has increased by 31%. This increase can be attributed to various human activities such as burning fossil fuels, deforestation, and industrial processes. These activities release large amounts of carbon dioxide into the atmosphere, contributing to the greenhouse effect and climate change. The 31% increase in carbon dioxide concentration highlights the significant impact of human activities on the Earth's atmosphere and the urgent need for sustainable practices to mitigate further increases.

The statement mentions that plant, animal, and insect species are being lost every single day due to rainforest deforestation. The answer "137" implies that 137 species are being lost every day. This number is within the given range of options and is a plausible estimate considering the extent of rainforest deforestation and its impact on biodiversity.
