On April 22, the world celebrates Earth Day. This symbolic anniversary of our planet serves an important purpose: to promote living in harmony with nature.
Date of Event
The first Earth Day was held in the United States in 1970 by Senator Gaylord Nelson. The event turned into a national environmental awareness demonstration. Later that year, the Environmental Protection Agency was also created. The movement has grown rapidly and at present, according to the official Network behind Earth DayAbout 1 billion people participate in Earth Day each year.
Similarly, in 1972 the United Nations organized a conference on the human environment in Stockholm. Thus began the era of global environmental awareness. Coincidence or not, but in 2009 the General Assembly designated April 22 as International Mother Earth Day† Mother Earth Day indicates that many nations are accustomed to referring to Earth as their “Mother”: we should all take care of our home together and be grateful for that. Both days today focus on combating climate change and inspiring people to be green.
How does space science fight climate change?
Every day is Earth Day when you see Earth from space. It has become abundantly clear that humans are only an infinitesimal part of the universe and that our Earth is at stake… space ship is that we must protect. After all, seeing the Earth from above helps to better understand its problems.
Space science contributes a lot to preventing and resolving climate change. For example, the Landsat missions, which are jointly carried out by NASA and the United States Geological Survey, examine the state of Earth’s forests and forests. The The data they collect about the Amazon rainforestHelps investigate the causes and consequences of the fire season and send warnings about deforestation. Another NASA mission, the Suomi National Polar-orbating Partnership (Suomi NPP), is also investigating thermal anomalies. In addition, this mission monitors changes in global ice cover, the health of the ozone layer, air pollution and other conditions on Earth.
The European Union’s Copernicus Sentinel missions, launched by the European Space Agency, are also collecting data on Earth’s health. They measure the behavior of the oceans, the mainland, and the atmosphere and provide an overview of disaster management to predict earthquakes and hurricanes. Dense accumulations of plastic in the sea can even be detected from above, such as Copernicus Sentinel It has been proven. Data from this satellite is now being used for this purpose. Indeed, these are not the only examples of how space science is helping us protect the Earth. Green technologies developed for space missions also have uses in daily life, such as Reusable water bottles with built in filters or flexible solar panels† Dozens of satellites in orbit and astronauts on the International Space Station studying Earth from above. Scientists analyze their data and suggest solutions. But without public participation, the scientific information provided will not help.
How can we all contribute?
You don’t have to be an astronaut or a scientist to celebrate Earth Day by taking action. Here is a list of activities that you can start on Earth Day and continue to do every day after that:
- picking up litter while walking;
- Turn off the lights when not in use;
- reduce your water consumption;
- plant a tree or Donate to a reforestation project†
- switch to e-books;
- Choose vegetable dishes.
- using a reusable water bottle;
- buy glass or paper products;
- use of environmentally friendly cleaning products;
- switch to reusable carrier bags;
- Participation in environmental projects as a volunteer.
Conclusion: Earth Day’s mission is to remind us that nature and man are inseparable. “When we see Earth from space, we see ourselves as a whole… one planet, one human race” – proverb Message in the context of Earth Day On April 22, 2020 by the European Space Agency and the Stephen Hawking Foundation. Everyone around the world is connected to our planet, Mother Earth. And we can all do our part to make the world a better place to live. So let’s do it!
