Traditional fossil fuels produce dioxide and emit harmful gases, making ecological damage almost inevitable. Long-term overuse will make ancient fossil resources completely dry up. 如今，人类活动不断耗尽自然资源、加剧生态破坏。传统化石燃料会释放二氧化物、散发有害气体，使生态环境受损几乎不可避免。长期过度开发，终将让古老的化石资源彻底枯竭。 To change this bad situation, we must optimize the energy structure and develop clean energy. Hydroelectric, geothermal and biomass energy are inexhaustible and environmentally friendly. We measure power consumption in kilowatt-hours and strictly implement energy-saving measures. 为改善这一不良现状，我们必须优化能源结构，积极发展清洁能源。水力、地热以及生物质能源用之不竭，是绿色环保的优质能源。我们以千瓦时为单位统计耗电量，并严格实施各类节能举措。 The construction of reliable energy infrastructure is very important. Advanced turbines and stable power grids greatly improve energy efficiency, which opens the door to long-term sustainable development. This positive scenario benefits both nature and human society. 搭建完善可靠的能源基础设施十分重要。先进的涡轮机与稳定的电力输电网，能够显著提升能源利用效率，为长期可持续发展创造机会。这一良性的发展方案，能够造福自然与人类社会。 Improper waste disposal will degrade the local ecological environment. Organic waste goes through natural decomposition in moist soil. If people ingest polluted food or randomly dump garbage, they will wind up facing serious environmental problems. 不规范的垃圾处理方式会破坏本土生态环境。有机废弃物可在湿润土壤中自然分解。倘若人们摄入受污染的食物、随意倾倒生活垃圾，最终只会面临严峻的环境难题。 We can recycle leftover food and edible plant waste to produce organic compost. Farmers hoe farmland and scatter natural fertilizer to help crops grow. Even food dough baked in an electric oven can follow green low-carbon rules. 中文译文：我们可以回收利用剩余的食物与可食用的植物废料，制作有机堆肥。农民通过锄地耕作、撒播天然肥料，助力农作物茁壮生长。即便是用电烤箱烤制的生面团，也可遵循绿色低碳的生产理念。 Severe ecological damage causes titanic-sized natural disasters. Tropical cyclones and strong storm surges frequently affect coastal regions. Seawater will seep into inland areas, causing wetlands and mangrove forests to gradually vanish. 严重的生态破坏会引发巨大的自然灾害。热带气旋与强烈的风暴激增现象，频繁侵扰沿海地区。海水会不断向内陆渗透，导致湿地与红树林植被逐步消亡。 In healthy ecosystems, grassland animals freely graze on green grass. Damaged land provides no refuge for wild creatures, and even crops such as pineapples fail to grow well. We must actively safeguard the natural environment, or the whole ecosystem will be in hot water. 在良好的生态系统中，草原动物可自由吃草、自在栖息生长。土地生态退化后，野生动物将无处避难，就连菠萝等农作物也无法正常生长。我们必须主动守护自然生态，否则整个生态系统终将陷入困境。 1 学科网（北京）股份有限公司 $
