a study has found that some of the world s most highly protected forests are emitting more carbon than they absorb, as a result of illegal logging and wildfires. at least ten forests designated unesco world heritage sites including yosemite national park in the united states were found to have been net carbon emitters over the last two decades. the findings have alarmed researchers, as forests are considered vital for curbing climate change because of their ability to act as carbon sinks. tanya dendrinos has more. for its emitting more carbon than they store. it may seem perplexing, the concept is simple. perplexing, the concept is sim - le. ~ . perplexing, the concept is simle. ~ . ., simple. when we cut down forests or simple. when we cut down forests or they simple. when we cut down forests or they are - simple. when we cut down i forests or they are burned, they will emit carbon into the atmosphere and it is a matter of how much forests we cut down
