The bar chart shows the change in carbon intensity per unit of GDP from 2005 to 2025, and the line chart displays China’s forest coverage rate from the 1950s to 2035. Carbon intensity dropped markedly over this period, falling to 18% by 2025 from its 2005 peak. Meanwhile, forest coverage rose steadily from 11.8% in the 1950s to 23% in 2020, with a further increase to 26% projected by 2035. This trend can be attributed to several factors. First, widespread tree planting helps absorb carbon emissions. Second, renewable energy use has reduced reliance on coal. Finally, the popularity of green travel has also lowered the carbon footprint. In conclusion, active efforts from everyone are essential to protect our environment. Through sustained action, we can enhance well-being and ensure a vibrant planet for the future. （Word count: 140）细胞中脂类含量由高到低排列
