Earth Day is an annual event on April 22 to demonstrate support for environmental protection.
First held on April 22, 1970, it now includes a wide range of events coordinated globally through earthday.org (formerly Earth Day Network) including 1 billion people in more than 193 countries.
In 1969 at a UNESCO conference in San Francisco, peace activist John McConnell proposed a day to honour the Earth and the concept of peace, to first be observed on March 21, 1970, the first day of spring in the northern hemisphere.
On Earth Day 2016, the landmark Paris Agreement was signed by the United States, the United Kingdom, China, and 120 other countries.
This signing satisfied a key requirement for the entry into force of the historic draft climate protection treaty adopted by consensus of the 195 nations present at the 2015 United Nations Climate Change Conference in Paris.
Numerous communities engaged in "Earth Day Week actions," an entire week of activities focused on the environmental issues that the world faces.
On Earth Day 2020, over 100 million people around the world observed the 50th anniversary in what is being referred to as the largest online mass mobilisation in history.
More on Earth Day:
- Earth Day is an international day officially celebrated since 1992. During the UN Conference on Environment and Development held in Rio de Janeiro, a far-reaching programme for promoting sustainable development was coordinated.
- In 2009, the UN General Assembly decided that it would be observed on April 22. The aim is to raise awareness among people about the natural environment and the wealth we possess.
- Minerals are the product of natural processes and a natural homogeneous component of the Earth's crust. They are most commonly found in a solid crystalline state and form through the process of crystallisation. Minerals can be crystallized, amorphous, or metamict.
-
The term crystallised substance, or crystal,
refers to the orderly arrangement of atoms in space within the sample.
Amorphous minerals lack a regular internal structure, while metamict minerals
were once crystalline but became amorphous due to the presence of a radioactive
element in their structure.
Bosnia and Herzegovina is rich in minerals that can be found in various localities and geological environments. Particularly notable for its beauty is Zepter Quartz, featured on the stamp, which was found in Busovača.
In the area covered by the Mostar Post, two associations are involved in promoting this topic – “Kreševski citrin" from Kreševo and the Croatian Mining-Geological Society Mostar.
