今天已有許多人意識到環保的重要，從政府到民間團體及個人，都熱心參與環保的工作。我們如果要生活得健康，居住得快樂，就要保護大自然，不要讓土地、河海和空氣受到污染與破壞。
大多數人認識到地理空間會影響我們生活的質素，但卻很少人留意心靈空間也一樣會影響我們的生活，尤其是影響我們的屬靈生活和品格的成長。語言環境就屬於心靈空間的一部分，直接影響著我們的屬靈生命。我們要保護生活中的語言環境，讓自己和身邊的人活得更開心、更健康。
若要保護空間環境，第一不要濫用和污染它，第二要藉著淨化和綠化，還原神創造時的美好。同樣地，我們要保護語言環境，首先不要濫用自己說話的權柄，用言語污染我們和別人共同分享的心靈空間。第二，我們要積極地使用言語來淨化美化這片心靈的天地，例如多說鼓勵的話，或用言語安慰憂傷的人等。
箴言裡有許多論及說話和語言的教導，因為神要我們善用自己的舌頭。你可以一一把它們找出來嗎？
Nowadays, people are more conscious about conserving our environment, from government to voluntary organizations, to individuals; everybody enthusiastically joins in the force of conserving the nature. If we want to live a healthy and happy life, we have to protect the nature, and don’t pollute the lands, rivers and seas or the air.
As matter of fact, many people have realized how geographical environment affects our living quality, but still ignore the impact that mental environment gives to our life, especially to our spiritual well being and character. Verbal environment is part of this mental environment, which will affect our spiritual well being. We should be responsible for conserving our verbal environment to allow others and ourselves to live happily and healthily.
If we want to conserve the natural environment, first of all, we should not abuse and pollute it; and then, through purifying and greening we restore the beauty of the creation. Likewise, if we want to conserve the verbal environment, we should not abuse our right of speech to pollute the shared mental environment. However, we should use our tongue positively to add beauty into the world of words, for instance, words of encouragement or comfort.
God has given us a lot of lessons regarding words and speech in the book of Proverbs. Can you list them out from the book to learn what God wants us to do with our tongue?
