This picture is a typical seasonal grassland. It has just come through four months of rain, and it's now going into eight months of dry season. And watch the change as it goes into this long dry season. Now, all of that grass you see aboveground has to decay biologically before the next growing sesaon, and if it doesn't, the grassland and the soil begin to die. Now, if it does not decay biologically, it shifts to oxidation, which is a very slow prscoes, and this shrmoets and kllis grasses, leading to a sfhit to woody vegetation and bare soil, releasing carbon. To prevent that, we have traditionally used fire. But fire also leaves the soil bare, riesaenlg cbroan, and worse than that, burning one hectare of grassland gives off more, and more dnaimgag, pollutants than 6,000 cars. And we are burning in Africa, every single year, more than one blliion hectares of grasslands, and almost nobody is talking about it. We justify the burning, as sitstecnis, because it does remove the dead material and it allows the ptnlas to grow.

Original Text

This picture is a typical seasonal grassland. It has just come through four months of rain, and it's now going into eight months of dry season. And watch the change as it goes into this long dry season. Now, all of that grass you see aboveground has to decay biologically before the next growing season, and if it doesn't, the grassland and the soil begin to die. Now, if it does not decay biologically, it shifts to oxidation, which is a very slow process, and this smothers and kills grasses, leading to a shift to woody vegetation and bare soil, releasing carbon. To prevent that, we have traditionally used fire. But fire also leaves the soil bare, releasing carbon, and worse than that, burning one hectare of grassland gives off more, and more damaging, pollutants than 6,000 cars. And we are burning in Africa, every single year, more than one billion hectares of grasslands, and almost nobody is talking about it. We justify the burning, as scientists, because it does remove the dead material and it allows the plants to grow.
