In ancient times, Gun attempted to control floods by blocking the water flow. Since this violated the natural patterns of water, the outcome was inevitably a failure.
In 1958, Beijing experienced a tragic event. To eliminate sparrows—one of the "Four Pests"—the municipal government mobilized citizens to drive them away relentlessly. The sparrows, forced to fly incessantly, often died of exhaustion. However, did the campaign succeed? The sight of sparrows foraging freely across Beijing today provides the answer.
During the SARS outbreak, while the virus was claiming lives, some officials ignored the gravity of the situation and attempted to hide the epidemic. By failing to recognize its severity, Beijing became a major hotspot. Had it not been for the intervention and criticism from the World Health Organization, which prompted timely corrective measures, the consequences could have been catastrophic.
Media reports indicate that many paper and chemical factories cause severe water pollution, yet environmental regulation remains insufficient. Because the fines are often much lower than the cost of treatment, companies frequently choose to pay the fines instead of treating their waste. Others resort to superficial compliance during inspections while discharging wastewater secretly. Consequently, the pollution of our rivers, lakes, and seas is worsening, posing a significant long-term threat to our environment.
Alas! When will we learn to respect and strictly follow the laws of nature instead of relying on misguided ingenuity?
古代鲧在治水时采取堵塞的方法，违背了流水规律，其结果自然以失败告终。
1958年，北京市曾经历过一件令人扼腕的事件。当时市政府为了消灭“四害”之一的麻雀，号召全市市民出动，不留死角地在各处驱赶这些可怜的小生物。麻雀们被迫不停飞行，许多都累死在途中。然而，麻雀真的被消灭了吗？如今北京随处可见麻雀自在觅食的景象，这便是最好的答案。
在非典时期，凶恶的病毒正在夺走生命，但个别官员却为了掩盖疫情而罔顾百姓死活，甚至自吹自擂。由于未能认识到疫情的严重性，导致北京成为了全球疫情严重的地区之一。若不是由于世界卫生组织的关注与批评，促使我们及时修正错误，后果将不堪设想。
据媒体报道，目前许多造纸、化工等工厂的废水污染严重，而环保监管却力度不足，罚款成本远低于治理成本，导致厂家往往选择交罚款而非治理污水。还有些企业采取虚假应对，在检查时表现良好，暗中却违规排放。这使得江河湖海的污染日益严重，恶劣的环境将成为我们面临的重大威胁。
唉！何时我们才能学会虚心尊重并严格遵循自然规律办事，不再一味地自作聪明呢？
