Ways to reduce the impact of the changes to the carbon and water cycles

Question 1

Carbon capture (carbon sequestration)
(def. and relevant to capture, transport and stroring)

Answer 1

The capture of carbon for long term storage
To limit CO2 entering the atmosphere
Can be human or natural
Human is using carbon capture technology

Can capture 90% of CO2 emissions
Captured by precombustion, post-combustion and as oxy-fuel combustion
Transport via pipeline or ship
Storing in underground depleted oil fields

Question 2

Example of carbon capture tech

Answer 2

Saskatchewan, Canada
1 million tonnes captured per year
Piped 66km to Weyburn oil unit

Question 3

Rural land use change

Answer 3

Avoid overstocking animals
Avoid overgrazing
Revegetation improve productivity
Irrigation improve plant productivity
Mulching prevents carbon loss
Reduce ploughing that could deplete soil carbon
Use of animal manure to increase plant productivity
Rotation of cash crops to increase soil fertility to increase plant productivity
Reforesting schemes
