International Earth Day

Harmony of Life: Celebrating Earth’s Biodiversity

 

Senator Gaylord Nelson of Wisconsin, after witnessing the devastation caused by a massive oil spill off the coast of California, in 1970 created a day dedicated to environmental awareness. Ever since, on April 22, we celebrate the Earth Day. The world’s largest initiative dedicated to the environment and the safeguarding of the planet we all live on.

Sustainability and biodiversity take center stage: from the depths of the oceans to the heights of the mountains, every creature and ecosystem plays a vital role.

Earth…

 

…has an atmosphere that extends from the planet’s surface up to approximately 10,000 kilometers above it.

The distance between the two farthest poles on Earth is estimated to be around 20,000 kilometers across the surface of the Earth: this is the distance between the Antarctic and the Arctic.


 

…is getting away from The Moon, which is slowly moving at roughly 4 centimeters annually.

This phenomenon is known as lunar recession and is caused by the gravitational interactions between the Earth and the moon. As the moon moves away, it causes a gradual slowing of Earth’s rotation rate.


 

…gives home to an estimated 8.7 million of species.

Although approximately 1.2 million species have been recognized and documented to date, the majority of them being insects, countless other life forms still elude our understanding.


 

…welcomes the Amazon rainforest, the habitat for 10% of the world’s wildlife species.

Despite covering only about 6% of the Earth’s land surface, the Amazon rainforest is considered the “Lungs of the Earth”. Spanning over 6.7 million square kilometers across South America, primarily in Brazil, but also extending into Peru, Colombia, and several other countries, it is one of the most biodiverse regions on the planet.


 

…is covered by Coral reefs which constitute the largest living structure.

Often referred to as the “rainforests of the sea” due to their high biodiversity, coral reefs support an estimated 25% of all marine species, despite covering less than 1% of the ocean floor.


 

…is called the “Blue Planet”: 71% of its surface is covered by water.

In the ocean, one can find 37 out of the 50 critical minerals. These are non-fuel minerals or mineral materials that fulfill two criteria: they are crucial for contemporary technologies, economies, or national security, and they have a vulnerable supply chain.


 

…‘s life is up to 80% found underwater.

Globally, marine fisheries sustain 57 million jobs and serve as the main protein source for over half of the population in least developed countries.


 

…stands alone as the sole planet with enduring, stable bodies of liquid water on its surface.

Multiple moons in our solar system are believed to contain significant amounts of liquid water beneath their surfaces. For instance, Enceladus, a moon of Saturn, and Europa, a moon of Jupiter, are two examples. These moons are thought to have salty, liquid oceans hidden beneath thick layers of surface ice.


 

…is facing a current pace of species decline ranging from 1,000 to 10,000 times faster than the natural extinction.

If current trends in greenhouse gas emissions persist, global warming is expected to cause the extinction of more than one-third of the world’s animal and plant species by 2050. This catastrophic loss would irreversibly diminish biodiversity and significantly impact ecosystems and human societies worldwide.


 

…is for ¼ covered by mountains, home to over 85% of the planet’s amphibians, birds, and mammals.

Mountain ecosystems offer diverse benefits to humans but face increasing threats from climate change: despite around half of the world’s biodiversity hotspots are now situated in mountainous areas, up to 70% of original habitats have been lost.
