The World is full of amazing creatures from every possible medium. From the birds of the air to the majestic whales of the sea, wildlife abounds in the most unusual and unexpected places. Wildlife benefits us in many ways, and has since time out of mind. World Wildlife day is a day to remind us of our responsibilities to our world and the lifeforms we share it with.
History of World Wildlife Day
On March 3rd, 1973 the United Nations General Assembly took a stand against to protect Endangered Species throughout the world.
Whether plant or animal, the importance of these species in every area of human life, from culinary to medical, could not be understated. At this time hundreds of endangered species were being threatened every year, and extinction was at a staggeringly high rate. CITES was put into place (Convention on International Trade in Endangered Species) to ensure that the world did not continue to hemorrhage species that would never be seen from again.
On December 20th, 2013 another step was taken to help spread awareness of the fragility of endangered species in the world. At its 68th session, the UN declared that each year World Wildlife Day would be dedicated to a new purpose and idea to help keep people abreast of the changing nature of our world, and the treasures we stand to lose from the animal and plant kingdom if we don’t take care.

“We need to encourage and support girls and women achieve their full potential as scientific researchers and innovators,” UN Secretary-General António Guterres said, with February 11 marking the International Day of Women and Girls in Science.

Science and gender equality are both vital for the achievement of the internationally agreed development goals, including the 2030 Agenda for Sustainable Development, the UN official website reports.

Over the past 15 years, the global community has made a lot of effort in inspiring and engaging women and girls in science. Unfortunately, women and girls continued to be excluded from participating fully in science. According to a study conducted in 14 countries, the probability for female students of graduating with a Bachelor’s degree, Master’s degree and Doctor’s degree in science-related field are 18%, 8% and 2% respectively, while the percentages of male students are 37%, 18% and 6%.

In order to achieve full and equal access to and participation in science for women and girls, and further achieve gender equality and the empowerment of women and girls, the United Nations General Assembly adopted resolution A/RES/70/212 declaring 11 February as the International Day of Women and Girls in Science.

Memory of the Victims of the Holocaust
International Day of Commemoration in Memory of the Victims of the Holocaust. It also
commemorates when the Soviet troops liberated the Nazi concentration and death camp Auschwitz-Birkenau in Poland on January 27, 1945.
January 27 is a special day to remember World War II’s holocaust victims.
Background 
The Holocaust, or Shoah (Sho, Shoa), is the term used to describe the deliberate
murder and desecration of millions of people prior to and during World War II in
Germany and German occupied areas in Europe. Many of them were Jewish but the
Roma people, Soviet civilians and prisoners of war, ethnic Poles, people with disabilities, homosexuals and political and religious opponents were also killed. Many people died in concentration and death camps spread across Nazi-occupied Europe. One of the most notorious camps was Auschwitz-Birkenau, near Oświęcim, Poland. More than one million people died in Auschwitz-Birkenau before Soviet troops liberated it on January 27, 1945.
On January 24, 2005, the UN General Assembly commemorated the 60th anniversary of the liberation of the Nazi concentration camps. Following this session, a UN resolution was drafted to designate January 27 as the International Day of Commemoration in Memory of the Victims of the Holocaust. The resolution called for education programs on the Holocaust to help prevent genocide. It also rejected denials that the Holocaust occurred. On November 1, 2005, the assembly adopted this resolution so the day could be observed each year. It was first observed on January 27, 2006.
Many Jewish groups, particularly in Israel, also observe Yom HaShoah , which is a day of mourning for Holocaust victims on 27th day of the Hebrew month of Nisan, which falls in April or May of the Gregorian calendar.

What Do People Do?
Holocaust survivors and various leaders make their voices heard on the International Day of Commemoration in Memory of the Victims of the Holocaust. Many of them speak
publicly about the Holocaust or their experiences around the event, its aftermath and why the world should never forget what happened in Europe in the 1930s and 1940s. Many statements emphasize the need for future generations to learn about and remember the Holocaust and for everyone to work towards preventing genocide.

The UN organizes and supports events such as: concerts by musicians who survived the Holocaust or are survivors’ descendants; art exhibitions influenced by the Holocaust;  presentations of special stamps; the introduction of special educational programs; and film screening and book signing focused on the Holocaust.
Israel and many countries in Europe and North America mark the International Day of
Commemoration in Memory of the Victims of the Holocaust. Many academics present
discussion papers or hold seminars or round table discussions on the Holocaust and its
legacy in the modern world. Schools or colleges may also have special lessons on the
Holocaust. The Holocaust and how people commemorate it receive special attention on
the Internet, television, radio, print media.

The United Nations (UN) International Migrants Day is annually held on December 18 to recognize the efforts, contributions, and rights of migrants worldwide.

On December 4, 2000, the UN General Assembly, taking into account the large and increasing number of migrants in the world, proclaimed December 18 as International Migrants. On that day, a decade earlier, the assembly adopted the International Convention on the Protection of the Rights of All Migrant Workers and Members of Their Families. Earlier celebrations of the day can be traced as far back as 1997 when some Asian migrant organizations marked December 18 as the day to recognize the rights, protection, and respect for migrants.

Background.
The International Day for the Abolition of Slavery, 2 December, marks the date of the adoption, by the General Assembly, of the United Nations Convention for the Suppression of the Traffic in Persons and of the Exploitation of the Prostitution of Others
( resolution 317(IV)  of 2 December 1949). The focus of this day is on eradicating contemporary forms of slavery, such as trafficking in persons, sexual exploitation, the worst forms of child labour, forced marriage, and the forced recruitment of children for use in armed conflict.
Main Forms of Modern Slavery.
Slavery has evolved and manifested itself in different ways throughout history. Today
some traditional forms of slavery still persist in their earlier forms, while others have
been transformed into new ones.
The UN human rights bodies have documented the persistence of old forms of slavery
that are embedded in traditional beliefs and customs. These forms of slavery are the result of long-standing discrimination against the most vulnerable groups in societies, such as those regarded as being of low caste, tribal minorities and indigenous peoples.
Forced labour.
Alongside traditional forms of forced labour, such as bonded labour and debt bondage
there now exist more contemporary forms of forced labour, such as migrant workers, who have been trafficked for economic exploitation of every kind in the world economy: work in domestic servitude, the construction industry, the food and garment industry, the
agricultural sector and in forced prostitution.
Child labour.
Globally, one in ten children works. The majority of the child labour that occurs today is
for economic exploitation. That goes against the Convention on the Rights of the Child ,
which recognizes “the right of the child to be protected from economic exploitation and
from performing any work that is likely to be hazardous or to interfere with the child’s
education, or to be harmful to the child’s health or physical, mental, spiritual, moral or
social development.”
Trafficking. 
According to the Protocol to Prevent, Suppress and Punish Trafficking in Persons
Especially Women and Children , trafficking in persons means the recruitment,
transportation, transfer, harbouring or receipt of persons, by means of the threat or use of force or other forms of coercion for the purpose of exploitation. Exploitation includes
prostitution of others or other forms of sexual exploitation, forced labour or services,
slavery or practices similar to slavery, servitude or the removal of organs. The consent of the person trafficked for exploitation is irrelevant and If the trafficked person is a child, it is a crime even without the use of force.
