    My point on enviromment pollution

    Do you agree or disagree that we should never tell lies to others?

    As the saying goes: honesty is the best policy. Yet, I fully agree that sometimes it is better not to tell the truth, that is, there are times when it would do more harm than good to reveal the true facts. My argument for this view goes as follows.

    Patient eagerly waits for the results from the doctor, amd the doctor's responsible is to choose whether to tell the patient truth or not.Because the emotion of the patient is one of the decisive factors in curing his/her illness,especially in the case of cancer.Maybe the doctor can comfort his patient to let him be less worried by choosing not to tell him the truth.So in my opinion, an experienced doctor should know if he can tell his patient truth ,and he must know that his words are important and influential to his patient.

    For a doctor, we may understand that sometimes it is better not to tell the truth. But “sometimes” deserves emphasis here. After all, honesty is one of the fine qualities of human beings. We should treat life in an honest way.

    環境污染

    人一直以為地球上的海、陸、空是無窮盡的,所以從不擔心把千萬噸廢氣送到天空去,又把數以億噸計的垃圾倒進海洋。大家都認為世界這麼大,這一點廢物算什麼?我們錯了,其實地球雖大(半徑6300多公裡),但生物只能在海拔8公裡到海底11公裡的範圍內生活,而佔了百分之九十五的生物都只能生存在中間約3公裡的範圍內,人竟肆意地從三方面來弄污這有限的生活環境。

    環境污染是指人類直接或間接地向環境排放超過其自淨能力的物質或能量,從而使環境的質量降低,對人類的生存與發展、生態系統和財產造成不利影響的現象。具體包括:水污染、大氣污染、噪聲污染、放射性污染等。水污染是指水體因某種物質的介入,而導致其化學、物理、生物或者放射性污染等方面特性的改變,從而影響水的有效利用,危害人體健康或者破壞生態環境,造成水質惡化的現象。大氣污染是指空氣中污染物的濃度達到有害程度,以致破壞生態系統和人類正常生存和發展的條件,對人和生物造成危害的現象。噪聲污染是指所產生的環境噪聲超過國家規定的環境噪聲排放標準,並幹擾他人正常工作、學習、生活的現象。放射性污染是指由于人類活動造成物料、人體、場所、環境介質表面或者內部出現超過國家標準的放射性物質或者射線。例如,超過國家和地方政府制定的排放污染物的標準,超種類、超量、超濃度排放污染物;未採取防止溢流和滲漏措施而裝載運輸油類或者有毒貨物致使貨物 落水造成水污染;非法向大氣中排放有毒有害物質,造成大氣污染事故,等等。

    隨著科學技術水平的發展和人民生活水平的提高,環境污染也在增加,特別是在發展中國家。 環境污染問題越來越成為世界各個國家的共同課題之一。
