Earth day quiz

Earth day will be celebrated on the 22nd of April. The 1st Earth day happened in 1970. 

Which of the following is a greenhouse gas?

1. CO2
2. CH4
3. Water vapour
4. A, B, and C

D: Greenhouse gases may be a result of natural occurrence or human activity. These gases include carbon dioxide (CO2), methane (CH4), water vapor, nitrous oxide (N2O) and ozone (O3). Fluorinated gases are also considered to be greenhouse gases. Greenhouse gases act like a heat-trapping blanket, making the Earth habitable for humans. However, human activities have increased emissions of greenhouse gases into the atmosphere beyond what the Earth can support, resulting in climate change.

How many liters of water does it take to make 1 pair of jeans?

1. 538 L
2. 270 L
3. 3781 L
4. 1123 L

It takes 3,781 liters of water to make one pair of jeans, from the production of the cotton to the delivery of the finished garment to a store. Textile manufacturing uses 20% of the world’s clean water each year.

What percentage of clothing is recycled?

1. Less than 10%
2. 57%
3. 26%
4. Less than 1%

Less than 1% of clothing is recycled. The repurposing of textiles is often incorrectly referred to as recycling. They are actually reused by being broken down and made into new products, often insulation or stuffing materials.

Which country has not run completely on renewable energy for a period of time?

1. Denmark
2. Portugal
3. The United States
4. Costa Rica

While some places in the United States have run on 100% renewable energy, such as Burlington, Vermont, the entirety of the country has not. Some countries that have run completely on renewable energy for a period of time include Denmark, who ran entirely on wind for a day; Portugal, who ran on wind, solar and hydropower for four days; and Costa Rica, who was powered by renewable energy for more than 100 days.

Which of the following is not considered to be a source of renewable energy?

1. Hydropower
2. Natural gas
3. Solar
4. Wind

According to the US Energy Information Administration, renewable energy sources, which re-generate, consist of biomass, hydropower, geothermal, wind and solar.

Which is one of the fastest growing renewable energy sectors in the world?

1. Solar
2. Biomass
3. Geothermal
4. None of the options

Solar energy is one of the fastest growing renewable energy sectors in the world. In 2018, solar energy produced just over 2 percent of the world’s electricity. Overall, renewable energy used for electricity has grown by around 7% in 2020

According to scientists, about how many countries could run entirely on wind, solar and water power by 2050?

1. 0
2. 20
3. 70
4. 140

According to a roadmap created by scientists, by 2050, nearly 140 countries could run on energy created solely from wind, solar and water power. They represent more than 70% of the world’s countries. Doing so could help avoid some of the consequences of climate change, while also preventing millions of premature deaths each year and generating jobs.

What percentage of the world’s forests have been destroyed?

1. 28%
2. 33%
3. 46%
4. 54%

What sector is the 2nd largest contributor to human-made greenhouse gas (GHG) emissions and is a leading cause of deforestation, water and air pollution and biodiversity loss?

1. Fossil fuels industry
2. Animal agriculture
3. Solar and wind
4. Transportation

Amsterdam is pursuing a circular economy. What does this mean?

1. The sharing, reusing and recycling materials and products for as long as possible.
2. Using the “Take-Make-Waste” model for resource consumption
3. They’re using the same economic system America does
4. An economy where everyone passes money around to each other in a circle

A circular economy is a reimagining of the way we use resources. If you chose the “Take-Make-Waste” model answer - it's the opposite of that! With that model, products and materials end up in landfills and cause tons of waste. A circular economy attempts to change that, mitigating waste and priding itself on regenerating natural systems.

The end!

Well done, hope you enjoyed, thank you!
