Preservation of the Ozone Layer
16th September, 2001

Save O3ur Sky: Protect Yourself & Protect the Ozone Layer
Your Comments Please - Guest Book

>> Preface

Dramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970s by a research group from the British Antarctic Survey (BAS) who were monitoring the atmosphere above Antarctica from a research station much like the picture to the right.

>> What Is The Ozone Hole?

The Ozone Hole often gets confused in the popular press and by the general public with the problem of global warming. Whilst there is a connection because ozone contributes to the greenhouse effect, the Ozone Hole is a separate issue. However it is another stark reminder of the effect of man's activities on the environment.

Over Antarctica and recently over the Arctic, stratospheric ozone has been depleted over the last 15 years at certain times of the year. This is mainly due to the release of manmade chemicals containing chlorine such as CFC's (ChloroFluoroCarbons), but also compounds containing bromine, other related halogen compounds and also nitrogen oxides (NOx). CFC's are a common industrial product, used in refrigeration systems, air conditioners, aerosols, solvents and in the production of some types of packaging. Nitrogen oxides are a by-product of combustion processes, eg aircraft emissions.

The current levels of depletion have served to highlight a surprising degree of instability of the atmosphere, and the amount of ozone loss is still increasing. GreenPeace have documented many of the concerns that this raises.

>> Ozone Day in Bangladesh

International Ozone Day will be observed in the country today as elsewhere around the globe. The day is being observed throughout the world since 1995 according to decision reached by the United Nations General Assembly to create mass awareness at the global level on depletion of the ozone layer and its harmful consequence.

This year's theme for the day is "Save Our Sky: Protect Yourself, Protect the Ozone Layer."

Chief Adviser Justice Latifur Rahman, in his message on the occasion, urged the decision and policy makers, planners, industrialists importers and scientists to pay due attention on imposing ban on use of ozone depleting substances.

In observance of the day, Environment and Forest Ministry has organised a painting competition and a seminar.

The painting competition for children and juveniles will be held at Shishu Academy at 2.30 pm.

The seminar will be held at Bangladesh Institute of Administration and Management at 10.30 am.

  • The Financial Mechanism
    The London Amendment (1990) to the Montreal Protocol on Substances that Deplete the Ozone Layer provided for the creation of a Financial Mechanism to assist developing countries. The Mechanism includes a Multilateral Fund and other multilateral, regional and bilateral co-operation. The Fund meets the incremental costs of the Parties operating under Article 5 of the Protocol (developing countries) to implement the control measures of the Protocol and finances all clearing house functions i.e. country studies, technical assistance, information, training and costs of the Fund Secretariat.
