How well do you know your home, our earth?
1970 being the first Earth Day ever, thanks to the idea of US Senator Gaylord Nelson, celebrating our home and its environment has been a 50 year old tradition that is dedicated towards making more wise and healthy choices for our planet earth.
Living a green lifestyle may sound like too much work, but as we all know, with little steps, big moves can be made.
So this Earth Day, let’s take a quiz to know how well we know our environment. Give yourself 5 points for every right answer. No peeking!
1. More than half of the breathable oxygen comes from
- a. Trees
- b. Ocean
- c. Sky
(b. Ocean. Majority of the oxygen we breathe is produced in the ocean by the teeny weeny phytoplankton)
2. Which energy source is not renewable?
- a. Petroleum
- b. Biomass
- c. Hydropower
(a. Petroleum. It is a fossil fuel that cannot be renewed. Think about switching over to friendlier means of transport?)
3. Which ecosystem holds most of the lifeforms i.e plants and animals?
- a. Tropical Forests
- b. Savannahs
- c. Prairies
(a. Tropical forests are home to at least 50% of all living things)
4. How long does a styrofoam cup take to decompose?
- a. 125 years
- b. 400 years
- c. 280 years
(b. 400 long years! Think before using styrofoam again?)
5. How much of the world’s water is available for our use?
- a. 2%
- b. less than 1%
- c. 3%
(b. Less than 1%. You might want to fix that dripping tap and think twice before using water unnecessarily)
6. What is the primary benefit of wetlands?
- a. Provide good place for land fills
- b. Help clean the water before it enters water bodies
- c. Keep the number of undesirable plants and animals low
(b. Help clean the water before it enters water bodies. They behave like a sponge to the environment)
7. There is still not a sure way to dispose nuclear waste. So what is usually done?
- a. Use it as nuclear fuel
- b. Dump it in landfills
- c. Store and watch over it
(c. Store and watch over it. Until a way to dispose it is found, it is best to store it in a safe place where it can cause no damage)
8. We produce a lot of household waste. Which of these is most hazardous?
- a. Plastic packaging
- b. Glass
- c. Batteries
(c. Batteries. They contain mercury and lithium which are very dangerous to the environment if not disposed properly)
9. Which animal is not an endangered species?
- a. The Maned Wolf
- b. Siberian Tiger
- c. Loggerhead Turtle
(a. The Maned Wolf. The biggest threat loggerhead turtles face is getting caught in fishing nets and degradation of nesting environment. The Siberian tigers fear the danger of poaching and again, habitat loss)
10. What is the most widely discussed impact of climate change?
- a. Increase in sea level
- b. Soil erosion
- c. Deforestation
(a. Increase in sea level. The global sea level has increased by 100-125 mm over the past 100 years. We are melting along with the ice sheets and glaciers. The gradual but steady rise in global temperature is greater than any seen in the past 10,000 years)
11. Which crop converts nitrogen from the air to inorganic nitrogen that the soil can absorb?
- a. Potato
- b. Bananas
- c. Lentils
(c. Lentils are also know as legumes. The soil needs nitrogen for enrichment and cannot directly absorb it from the air. Legumes are the only crops that can help convert it to inorganic forms and must be used as a rotation crop to maintain soil)
12. Who coined the word ecology?
- a. Charles Darwin
- b. Ernst Haeckel
- c. Gregory Mendel
(b. Ernst Haeckel. He was a German zoologist who used this term in relation of the animals to their organic and inorganic environment. Not Charles Darwin guys!)
Your Earth Day Score:
0-15: You are like the El Gordo galaxy – located 9.7 billion light years away from the earth. You have little or no clue about the planet you live in.
15-35: You are like the Coral reefs. They exist and we are faintly aware of their importance, but then again, not so much.
35-60: You are Mother earth’s faithful sidekick. You are well aware of the environment you live.
