   For carbon dioxide, we've always known about power plants and smokestacks and things like that ; but with methane, until recent years, we didn't understand how much an influence a small number of large sources have really had, we didn't understand how long the tail was and how important the super-emitters were for reducing emissions.

4. Raj Dasgupta:

   Normal breathing is a balance between breathing in oxygen and breathing out carbon dioxide. When you upset this balance by exhaling more than you inhale,( it) causes a rapid reduction in carbon dioxide in the body, low carbon dioxide levels lead to narrowing of the blood vessels that supply blood to the brain. This reduction in blood supply to the brain leads to symptoms like lightheadedness. This is why it is often recommended to start slowly and practice three to four cycles at a time until you are comfortable with the technique.

5. Matthew Sullivan:

   In the last 20 years or so, weve learned that half of the oxygen that we breathe comes from marine organisms, additionally, the oceans soak up half of the carbon dioxide from the atmosphere.
