Stop driving cars
If humans continue doing nothing to reduce their impact on the carbon cycle then the levels of carbon dioxide in the atmosphere will continue to rise.
We have to reduce the emissions of carbon dioxide and methane, the greenhouse gases, into the atmosphere.
A carbon sink is a storage for carbon. A tree is a carbon sink because it absorbs carbon dioxide (a greenhouse gas) from the atmosphere, stores the carbon and releases the oxygen. So forests are major carbon sinks which reduce the levels of greenhouse gas in the atmosphere.
passing laws requiring reduction in emissions
When you burn fossil fuels to make enrgy, carbon dioxide is released. So, if you burn less fossil fuels, less carbon dioxide is released.
If you want to reduce your carbon footprint, you can reduce your emissions of CO2 (carbon dioxide) into the atmosphere.

No, only vegetation growing removes carbon dioxide from the atmosphere.

To reduce the amount of carbon dioxide in the atmosphere, scientists are planting more green plants e.g. forests. Green plants require carbon dioxide for photosynthesis.

Cellular respiration uses oxygen and generates carbon dioxide. Photosynthesis uses carbon dioxide and generates oxygen.
Bio fuel emits carbon dioxide (CO2) that was removed from the atmosphere when the plant grew (this year, probably). Fossil fuels (coal, oil and natural gas) emit carbon dioxide that has been hidden away for millions of years. So using biofuel instead of fossil fuel means that less carbon dioxide is added to the atmosphere.
No

Solar powered buildings and cars reduce carbon dioxide that is added to the atmosphere because instead of having the process of burning like fossil fuels they take in the light energy from the sun, store and use it.
