History of the Earth Day


In the Beginning...
In 1963, former Senator Gaylord Nelson began to worry about our planet. (A senator is a person that the people of the United States have chosen to help make the laws.) Senator Nelson knew that our world was getting dirty and that many of our plants and animals were dying.
He wondered why more people weren't trying to solve these problems. He talked to other lawmakers and to the President. They decided that the President would go around the country and tell people about these concerns. He did, but still not enough people were working on the problem.

The Idea
Then, in 1969, Senator Nelson had another idea. He decided to have a special day to teach everyone about the things that needed changing in our environment. He wrote letters to all of the colleges and put a special article in Scholastic Magazine to tell them about the special day he had planned. (Most of the schools got this magazine and he knew that kids would help him.)

The Holiday
On April 22, 1970, the first Earth Day was held. People all over the country made promises to help the environment. Everyone got involved and since then, Earth Day has spread all over the planet. People all over the world know that there are problems we need to work on and this is our special day to look at the planet and see what needs changing. Isn't it great?

The Earth Day is also a good day to tell something about our planet. As I have read today in the morning the Sun stopped to go on with its normally 11 years long activity cycle . Its radiation is the lowest this days since last 55 years. And the number of sun surface spots is the lowest since last 100 years. The scientists suspect that the Sun can come back to its normal cycle though some of them think those changes can be a beginning of next Sun activitity minimum – what means next Little Ice Age in practice. Such Sun activity minimums happened three times during last 1000 years. These years of so called Little Ice Ages are known as:
- Sporer minimum (1420-1570)
- Maunder minimum (1645-1715)
- Dalton minimum (1790-1830)

Baltic Sea has been frozen during those Little Ice Ages.

What do you think about this fact? Do you agree it is the truth?

Now at the end some Sahara music – that example what can happen when Sun shines really hard:
