Kila tarehe 16 Septemba, dunia huadhimisha Siku ya Kimataifa ya Hifadhi ya Tabaka la Ozoni ili kuongeza uelewa kuhusu umuhimu wa tabaka hili katika kulinda uhai duniani. Maadhimisho haya yalianza baada ya kuidhinishwa kwa Itifaki ya Montreal mwaka 1987, lengo kuu likiwa ni kuhakikisha tabaka la ozoni linalindwa dhidi ya athari za kemikali zinazoliharibu.

Tabaka la ozoni ni kinga muhimu inayochuja miale mikali ya jua, hasa miale ya urujuanimno (UV), ambayo ni hatari kwa viumbe hai. Bila uwepo wa tabaka hili, maisha duniani yangekumbwa na matatizo makubwa kama vile ongezeko la saratani ya ngozi, magonjwa ya macho, na uharibifu wa mazingira, ikiwemo viumbe vya baharini.

Mafanikio ya Itifaki ya Montreal katika kupunguza kemikali zinazoharibu ozoni yamekuwa ya kutia moyo, huku jamii ya kimataifa ikiendelea kuchukua hatua madhubuti. Kupitia mikataba na marekebisho kama yale ya Kigali mwaka 2016, nchi nyingi zimekubaliana kupunguza uzalishaji wa gesi zinazochafua mazingira na kuchangia kwa mabadiliko ya tabianchi.

Kaulimbiu za maadhimisho haya hutofautiana kila mwaka, zikilenga kuhamasisha watu na serikali kuongeza juhudi katika kulinda tabaka la ozoni na mazingira kwa ujumla. Siku hii ni fursa ya kuonyesha jinsi hatua za pamoja zinaweza kuleta matokeo chanya na kutukumbusha kuwa kulinda mazingira ni wajibu wa kila mmoja wetu kwa vizazi vya sasa na vijavyo.

The hole in the ozone layer has more to do with politics than deodorants, a French scientist tells Ian Phillips.

If there is one thing Haroun Tazieff believes in, it is speaking his mind. "When I've got something to say, I say it," he asserts. In the past, France's most famous volcano expert has raged about everything from the Mafia to television presenters, but in recent years he has found a new hobby-horse - the ecological lies he believes Green politicians have invented to scare the electorate into voting for them.

One of his favourites is the disintegration of the ozone layer by the infamous CFC gases. "It's a complete lie," he told me vehemently, when we met in Paris recently. "The ozone hole is a natural hole which appears above the Antarctic at the beginning of October and has disappeared by the end of December. In Europe, I think I'm the only person to refute it, and I have never been officially contradicted, neither by ecologists nor by scientists.
