Rockstrom gives the example of the Baltic Sea which used to contain high quantities of cod, but now contains none because of fertilizer pollution from surrounding fields.
What other animal from the ocean helps fight climate change?
A) Killer whales
B) Sea otters
B) Sea otters
Sea otters help ecosystems capture carbon from the atmosphere and store it as biomass and deep-sea detritus, preventing it from being converted back to carbon dioxide and contributing to climate change.
Phytoplankton account for about half of the photosynthesis on the plant.
A) True
B) False
A) True
Making them one of the world's most important producers of oxygen. Like plants, phytoplankton capture large amounts of CO2 and convert it to energy, removing carbon from the atmosphere.
What type of bee are valuable insects to a functioning crop-growing agricultural system due to their ability to pollinate and improve the health of plants?
A) Bumblebee
B) Honeybee
A) Bumblebee
British scientists upset Sweden by taking 100 queen bees from them to release the bees back into the UK to revive the bumblebee population. When a country that feels forced to go to another country to steal pollinators to help its own agriculture... it's serious.
Globally, which of the following economic sectors emits the largest percentage of greenhouse gas emissions?
A) Industry
B) Electricity and heat production
B) Electricity and heat production
The electricity and heat production sector emits the largest percentage of global greenhouse gas emissions at 25%. The agriculture, forestry and other land use sector is a close second at 24%.
Which reef provides protection against flooding and erosion of coastlines?
A) Barrier reef
B) Coral reef
B) Coral reef
Without coral reefs, there will be rapid erosion of coastlines and many small island countries might even vanish from the world map.

A) 2016
B) 2020
C) All of the above
C) All of the above
2020 has effectively tied 2016 as the hottest year on record, with the global average temperature 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean. The last seven years have been the warmest seven years on record.

A) True
B) False
A) True
More than a third of food produced globally never makes it to the table. Some of this wasted food spoils in transit, while consumers throw some of this food out. Food loss and waste account for around 8.2% of the total humanmade greenhouse gas emissions.
Of a world without _____, would be a gigantic failure for humanity that would affect everything from coral reefs to food security and climate change.
A) Fish
B) Sharks
B) Sharks
Once sharks are gone, there is nothing we can do to replace the critical role they play in the balance of the oceans.
What was agreed to in the "Paris Agreement" that came out of COP-21, held in Paris in 2015?
A) To protect biodiversity and end the deforestation of the world's rainforests.
B) To keep global temperature rise well below 2 degrees Celsius pre-industrial levels and to pursue a path to limit warming to 1.5 degrees Celsius.
B) To keep global temperature rise well below 2 degrees Celsius pre-industrial levels and to pursue a path to limit warming to 1.5 degrees Celsius.
The Paris Agreement is an international treaty on climate change. It aims to keep the overall increase in global temperatures below 2 degrees Celsius, with the hope of limiting it to 1.5 degrees Celsius. Scientist believe that these are the largest increases in global temperature that we could experience without causing catastrophic change to the Earth's climate.
Which of the following is a greenhouse gas?
A) CO2
B) CH4
C) water vapor
D) All of the above
D) All of the above
Greenhouse gases may be a result of natural occurrence or human activity. 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.
