Biochar lower carbon emissions

Biochar not only improves soil but also helps lower carbon emissions in the atmosphere.

Biochar can act as a way to store carbon for a long time, capture carbon from the atmosphere and store it in the Earth. In Biology class, we learned that plants take in carbon dioxide from the air and water from the soil, and use sunlight to grow through photosynthesis. They store carbon in their fruits, stems, and roots, and become one of the major food sources for the other living organisms, including us. At the end of their life, when plants die, microorganisms break them down, and the remaining plant matter decomposes into the soil, releasing carbon back into the air as carbon dioxide. To make it worse, farmers usually burn the crop waste, which immediately causes a lot of carbon dioxide pollution.

If farmers utilize crop waste to make biochar, the production of carbon dioxide from the de-composition process or from burning can be eliminated, and farmers get something useful to improve their soil. Biochar can stay in the soil for hundreds of years. By doing this, we can help lower the amount of carbon dioxide in the air and support the fight against climate change, helping to prevent the Earth from getting 1.5°C hotter.
