Scientists used satellite data and a computer model to study how much plants in East Asia grew between 2000 and 2005. They found that the plants there made about 21.7 trillion pounds of carbon, with 10.5 trillion pounds staying in the plants. The model worked well, predicting plant growth accurately. In different regions, plant growth varied a lot – some places had a lot of growth while others had very little. Countries like Mongolia had the most plant growth per person compared to countries like India. The differences were mostly because of the weather in those areas. The study shows how plants in East Asia use carbon from the air to grow, with some places being much better at it than others.
