Experts believe the natural pristine forests of Iran, belonging to the Hircanian age, probably date back to between 2-3 million years ago. These natural forests are a natural reservoir of diverse flora and fauna and exceptional beauty. They comprise up to 4% of the country's area and are under constant pressure from legal and illegal logging, urbanization and industrialization projects. Situated at the north of Iran andsouthern border of the Caspian sea, these forests are a natural touristic attraction for millions of people who visit the north every year.
Since two years ago, State officials announced plans to construct a highway passing between the Nowshahr Botanical Gardens in Mazandaran. This botanic reservoir which dates more than 5 decades ago is a unique collection of living plants many of which are at the verge of extinction. Many of these plants are also ornamental as well. In addition to research and education, the Garden is a touristic attraction as well. At that time many NGOs and environmental activists opposed the action and certain members of the Garden administration filed a legal claim against the local authorities. This led to a judicial verdict and the plans were temporarily cancelled.
Last week a new directive was issued to begin the destruction of the Garden on Wednesday. NGOs and civil society activists began a campaign to protest against the action and to prevent the government from executing its directive. They also signed a petition asking Dr. Rouhani the President elect to take action to prevent the destruction of this valuable biodiversity reservoir.
NGOs arrived on the site on Wednesday to see that the directive has been temporarily annulled and construction activity cancelled.

Recent Presidential elections resulted in the victory of the moderate candidate who called for change. This event indicates that the winds of change are on the way and there is much reason for optimism.
تا چند سال پیش، از مضرات گازهای گلخانه ای، تنها بر گرم شدن زمین تاکید می شد. اما گرم شدن زمین تنها شروع یک فرایند بزرگ تر است. گرم شدن زمین باعث آب شدن یخچال های طبیعی از جمله بزرگترین یخچال یعنی یخچال قطب شمال شده است. با اب شدن این یخ ها، غلظت آبهای اقیانوس ها کم شده و فرایند تبخیر سرعت یافته و رطوب جو نیز به صورت چشمگیری افزایش می یابد.
ReplyDeleteاین افزایش رطوب علاوه بر کاهش نسبی دما (بر اساس تعریف شیمی، تبخیر دمای محیط را جذب می کند) باعث بارندگی ها غیر عادی می شود. امسال در ایران بر خلاف سال های قبل تابستان خیلی گرمی تا الان نداشتیم و حتی اوایل تابستان بارندگی هم رخ داد.
برفی که طی دو روز گذشته در مکزیک باریده، از نشانه های جدی تاثیرات گازهای گلخانه ای هست.
ولی هنوز نه گروه های طرفدار محیط زیست قضیه رو علنی کردن و نه سیاستمداران .
