Final answer:
The correct answer is B, which describes how carbon dioxide removal technologies aim to lower the current level of carbon dioxide in the atmosphere through methods like carbon capture and sequestration, as well as ecosystem restoration.
Step-by-step explanation:
These technologies, including carbon capture and sequestration (CCS) and direct air capture, actively remove CO2 from the atmosphere or prevent it from being emitted in the first place. By capturing the carbon dioxide and storing it underground or using other methods, we can reduce the concentration of this key greenhouse gas and mitigate the effects of climate change.
Restoration of natural ecosystems, such as forests, grasslands, and wetlands, also plays a crucial role in sequestering carbon dioxide, as these are natural sinks that absorb and store carbon. The planting of new forests and management of existing ones can store significant amounts of carbon and can be seen as a form of planetary engineering.
Government policies must encourage and support the deployment of these technologies through subsidies or regulation to ensure their widespread use. This concerted effort can lead to a decrease in atmospheric CO2 levels, thereby combating global warming and promoting a healthier planet.
