IB ESS HL 2.3.11 Alleviating Carbon Cycle Impacts Topic Practice

a. reforestation/afforestation initiatives so that more carbon can be absorbed;
b. carbon capture and storage/CCS to bury $\mathrm{CO}_{2}$ underground;
c. land use change/urban renewal leading to revegetation/green roofs to absorb $\mathrm{CO}_{2}$;
d. switch to renewable energy to reduce use of fossil fuels;

Note: There are multiple acceptable responses to this question i.e. any process that reduces release of $\mathrm{CO}_{2}$ or absorbs $\mathrm{CO}_{2}$ from atmosphere NB This is an "outline" question, not "identify", so requires a little more than "reforestation" (i.e. WHY reforestation?) or "reduce use of fossil fuels" (...need to state HOW fossil fuel use might be reduced),
