Which one of the following statements is TRUE?
Correct Answer
A. The United Nations Food and Agriculture Organization suggested humans to eat insects in a recent report.
Explanation
The UN Food and Agriculture Organization (FAO) released a report entitled, “Edible Insects: Future Prospects for Food and Feed Security” wherein they suggest that eating insects would feed the hungry populations across the globe. The report asserts: “Insects are healthy, nutritious alternatives to mainstream staples such as chicken, pork, beef, and even fish.” Eating insects is environmentally-friendly because agricultural land is not necessary. Fewer greenhouse gases would be emitted and the flatulence cows produce would not contribute to the deteriorating atmosphere. The report surmises that: “Western attitudes of disgust towards eating insects have arguably also influenced the preference of people in tropical countries.

Nemo was a baby clown-fish who got kidnapped from the Coral sea by humans in ships to Sydney (800 km away).
How did Nemo's father Marlin reach Sydney quickly before the evil human kid Darla could kill Nemo?
Correct Answer
C. By getting into a warm ocean current that swept Marlin to Sydney
Explanation
The East Australian Current (EAC) is an ocean current that moves warm water in a counterclockwise fashion down the east coast of Australia. It is the largest ocean current close to the shores of Australia. Its source is the tropical Coral Sea off the north-east coast of Australia. It can reach speeds of up to 12 km/hr in some of the shallower waters along the Australian continental shelf. The EAC also acts to transport tropical marine fauna to habitats in sub-tropical regions along the southeast Australian coast.

If you were to conduct a Carbon life-cycle analysis on a typical grocery store such as Sainsbury's ,
you will be surprised to know that the maximum amount of carbon emissions occur due to:
Correct Answer
D. Their supply chain
Explanation
The correct answer is "Their supply chain." Conducting a carbon life-cycle analysis on a typical grocery store like Sainsbury's would reveal that the maximum amount of carbon emissions occurs due to the store's supply chain. This includes transportation of goods, packaging materials, and the energy used in the production and distribution processes. Supply chains often involve long distances and multiple intermediaries, leading to significant carbon emissions. Therefore, addressing and improving the sustainability of the supply chain can have a substantial impact on reducing carbon emissions in the grocery store's operations.
