Earth Day began on April 22, 1970 and has been an important day ever since. It's a day to reflect on our planet, our environment and what we can do to help keep them healthy.
From the beginning, children and schools were approached to support the formation and continuation of this special day. And this makes sense! Children have the most important stake in keeping our planet healthy. They'll still be the caretakers long after their parents and grandparents have passed away.
What Did Earth Day Accomplish?
Well, after the first earth day in 1970 here's what happened:
The Environmental Protection Agency was established later in 1970.
The tough Clean Air Act of 1970 was passed.
The Federal Occupational Health and Safety Act aimed at "in-plant pollution".
Other countries have accomplished similar achievements.
But this is one of those jobs that's never complete. Global warming and other issues never conceived of in 1970 are now common themes on the news.
What Did Earth Day 1990 Achieve?
The UN Earth Summit in Rio de Janeiro. The Earth Summit was the largest collection of national political leaders ever to meet in one place. It made some important initial steps toward addressing climate change and preserving biodiversity.
More than a dozen countries established eco-labeling programs to guide consumers toward environmentally preferable goods and services.
Several Eastern European nations, responding to public demand, established new environmental protection agencies.
CARE, the international relief agency, set out new environmental goals for itself in the 1990s that include planting 500,000,000 trees worldwide.
And in the new millenium there's still lots to do!
But, What Can I Do?
All these big "news stories" are great, but what does that really have to do with you and me? I mean, we're not part of the U.N. Or anything important like that.
But we are important! If it's important to us, then it's important to our leaders. You can start with things like using recycled items in your crafting (most of the items on this site are!). You can learn about your local areas recycling program. Help your parents sort the recycling. Encourage them to recycle (donate some of your allowance to purchase a small home recycle bin -- now that will get their attention!) This is one of those times where the kids may be teaching the parents.
You can do the same thing at school, clubs, home and anywhere else you spend time.
Let others know what you've done! Write a letter to your local government representative and let them know how much you care about the environment and what work you've put in to improve it. There's nothing more inspiring than seeing people put thought into action! It's simple to write to someone and say, "Hey! Fix the environment!" but it's more convincing if that same note read, "Hey! Here's what I'm doing to help fix the environment!! Do you have any ideas on what else I could do? What are you up to to solve the same problem?"
But the most important part is to be aware and make others aware every day of the year!
Our solar neighborhood is an exciting place. The Solar System is full of planets, moons, asteroids, comets, minor planets, and many other exciting objects.
What Is The Solar System?
The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas.
Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space. The result of the planets trying to fly away, at the same time that the Sun is trying to pull them inward is that they become trapped half-way in between. Balanced between flying towards the Sun, and escaping into space, they spend eternity orbiting around their parent star.
How Did The Solar System form?
This is an important question, and one that is difficult for scientists to understand. After all, the creation of our Solar System took place billions of years before there were any people around to witness it. Our own evolution is tied closely to the evolution of the Solar System. Thus, without understanding from where the Solar System came from, it is difficult to comprehend how mankind came to be.
Scientists believe that the Solar System evolved from a giant cloud of dust and gas. They believe that this dust and gas began to collapse under the weight of its own gravity. As it did so, the matter contained within this could begin moving in a giant circle, much like the water in a drain moves around the center of the drain in a circle.
At the center of this spinning cloud, a small star began to form. This star grew larger and larger as it collected more and more of the dust and gas that collapsed into it.
Further away from the center of this mass where the star was forming, there were smaller clumps of dust and gas that were also collapsing. The star in the center eventually ignited forming our Sun, while the smaller clumps became the planets, minor planets, moons, comets, and asteroids.
A Great Storm
Once ignited, the Sun's powerful solar winds began to blow. These winds, which are made up of atomic particles being blown outward from the Sun, slowly pushed the remaining gas and dust out of the Solar System.
With no more gas or dust, the planets, minor planets, moons, comets, and asteroids stopped growing. You may have noticed that the four inner planets are much smaller than the four outer planets. Why is that?
Because the inner planets are much closer to the Sun, they are located where the solar winds are stronger. As a result, the dust and gas from the inner Solar System was blown away much more quickly than it was from the outer Solar System. This gave the planets of the inner Solar System less time to grow.
Another important difference is that the outer planets are largely made of gas and water, while the inner planets are made up almost entirely of rock and dust. This is also a result of the solar winds. As the outer planets grew larger, their gravity had time to accumulate massive amounts of gas, water, as well as dust.
The Solar System Has Over 100 Worlds
It is true that there are only eight planets. However, the Solar System is made up of over 100 worlds that are every bit as fascinating. Some of these minor planets, and moons are actually larger than the planet Mercury!
Others, such as Io, have active volcanoes. Europa has a liquid water ocean, while Titan has lakes, rivers, and oceans of liquid Methane. You can read more about these amazing worlds by clicking here.
Sure you'll enjoy it because you'll be able to travel to the depths of the Universe and learn about deep space; or become an amateur astronomer learning to observe the sky
... and relax yourself singing and dancing these three beautiful songs:
Have a nice and restful holiday to be ready for next year!

Tal día como hoxe, 20 de maio, hai 508 anos finaba en Valladolid, Cristóbal Colón, mariñeiro, cartógrafo e descubridor de América. Prema neste enlace e descobre a súa vida.
Who was Columbus? Columbus was an explorer. In 1492, he sailed from Europe to America. He and his sailors crossed the Atlantic Ocean, not knowing where they would land. It was a voyage into the unknown. After Columbus, other Europeans began to explore and settle in America.
When did he live? Christopher Columbus was born in 1451. It was a time of new ideas and discoveries in Europe. We call this time the Renaissance - a word that means 'rebirth'. People were making maps of new lands. They were building ships to explore places they had never visited before.
What did Columbus do? Columbus did not 'discover' America. There were many people already living there. Vikings from Europe had landed in America 500 years before. But Columbus did not know that. His voyage started regular contact between America and Europe.
St George’s Day is celebrated on the 23rd April. St George is
the patron saint of England and his emblem, a red cross on a white flag forms
the flag for England. St George was a brave Roman soldier who died fighting for
his beliefs. There is also a legend that he fought and killed a dragon!
