WORLD TOURISM DAY

 

    

    27 September - World Tourism Day

World Tourism Day is annually celebrated on 27 September to highlight the importance of tourism which helps in generating employment and build a future for millions of people around the world. 

    The aim of celebrating World Tourism Day is to highlight the global significance of tourism as a tool for global development and cultural enlightenment. No doubt countries all over the world whether big or small some or the other way depend upon the tourism for its economic survival and  highlight their cultural, social and political values. It is a unique opportunity to raise awareness on tourism and potential contribution to sustainable development.

INTERNATIONAL DAY OF PEACE

 

   

 21 September - International Day of Peace (UN)

International Day of Peace (UN) is observed on 21 September around the world. For the first time it was observed in September 1982 and in 2001, the General Assembly adopted a resolution 55/282, which established 21 September as International Day of Peace of non-violence and cease-fire.

 

    International Day of Peace 2020: Theme

The theme of the International Day of Peace 2020 is 'Shaping Peace Together'. As per UN, celebrate the day by spreading compassion, kindness and hope in the face of the pandemic. Stand together with the UN against attempts to use the virus to promote discrimination or hatred.

RESPECT DAY

 

                                            Taking part each September, Respect Day has been created to encourage people to focus more on ways in which they can be respectful to others.

For many the day involves being more attentive to loved ones, but it can really be used as a catalyst for treating any people with a more polite approach.

There are no rules surrounding ways in which you could celebrate this year, it’s really down to you. You could take your wife or husband out for a romantic meal, you could visit an elderly relative or you could endeavour to be more encouraging to others.

Of course, respect isn’t something that should only be given once a year and hopefully the day will inspire people to think more about how they treat others all year around.

Because of Respect Day’s broad nature, news coverage is likely to be limited so it is advisable to just mark the date in your diary and try your best.

WORLD OZONE DAY

 

    16 September - World Ozone Day

World Ozone Day is observed on 16 September annually. On this day in 1987, the Montreal Protocol was signed. Since 1994, World Ozone Day is celebrated which was established by the United Nations General Assembly. This day reminds people about the depletion of the Ozone Layer and to find solutions to preserve it.

    We all know that ozone protects us from UV rays coming from the sun. In 1957, Professor Gordon Dobson of Oxford University discovered the ozone layer. Ozone is made up of three atoms of oxygen. It is a highly reactive gas and is represented by O3. It occurs naturally as well as a man-made product in the Earth's upper atmosphere,i.e. stratosphere and lower atmosphere,i.e. troposphere. That is the Ozone layer is present in Earth`s atmosphere (15-35km above Earth) in the lower portion of the stratosphere and has relatively high concentrations of ozone (O3). Naturally, it is formed through the interactions of solar ultraviolet (UV) radiation with molecular oxygen O2. It reduces the harmful UV radiation reaching the Earth's surface.

    But at the ground-level ozone is considered as a major air pollutant. We all know that ozone protects us from harmful UV radiation but ozone at ground level is dangerous and causes pollution. Due to human activities, the ozone layer is getting depleted on the planet which could be very disastrous. It also causes photochemical smog and acid rain.

Causes of Ozone Depletion

The main cause of depletion of the Ozone layer is human activity mainly human-made chemicals that contain chlorine or bromine. These chemicals are known as ODS that is Ozone - Depleting Substances. Since the early 1970's scientists observed a reduction in stratospheric ozone and it was found more prominent in Polar Regions. Do you know that one molecule of chlorine has the capability to break down thousands of ozone molecules? The chief ozone-depleting substances include chlorofluorocarbons (CFCs), carbon tetrachloride, hydrochlorofluorocarbons (HCFCs), and methyl chloroform. Halons, sometimes known as brominated fluorocarbons, also contribute mightily to ozone depletion. ODS substances have a lifetime of about 100 years.
