Human Intervention carbon cycle

Question 1

Explain CCS

Answer 1

At factory or powerplant, Co2 emissions are caught, converted to a liquid and then piped underground into an old gas or water store/Aquifer.

Question 2

Advantages of CCS

Answer 2

Reduces carbon in atmosphere
Doesn’t stop or get in the way of economic activity

Question 3

Disadvantages of CCS

Answer 3

Expensive (e.g. Fife and Kent schemes were cancelled due to cost.)
Limited amount geologically suitable places
Encourages use of fossil fuels.

Question 4

Give examples of CCS

Answer 4

Endurance

Question 5

Explain Afforestation

Answer 5

Reducing open land with fast growing trees to create plantation forests. More trees more photosynthesis, more co2 sequestration.

Question 6

Give example of Afforestation

Answer 6

New Forest UK
Or
Sundarbans, The Livelihood Fund (Planted over 16 million mangroves in the Sundarbans.

Question 7

Advantages of Afforestation

Answer 7

Provide habitats
Sustainable Logging
Reduce Flooding

Question 8

Disadvantages of Afforestation

Answer 8

Time intensive
Space (for the plantation forests to grow)
Can look unnatural

Question 9

Aviation strategies to reduce emissions

Answer 9

Flight management:
ensure 100% occupancy
Lower speeds (less emissions)
More fuel efficient routes

Design:
More efficient engines
Improved aerodynamics
reduce weight
CCS in engines
