When we started developing the website, we read the posts of Rosane regarding Environment & Manking in our orkut community. She reflects the things so nicely that it is understood very easily by all. So, an idea came to our mind to present her knowledge and innovation through blogs by attaching it to our website. In this way, we can help lots of people (that is the mission of our group).

When we sent her a mail discussing this idea, we got a reply in a day. You yourself read her views on writing the blog:

"The peace I have today is different from the peace I’ve dreamed one day.
Only with time, have I learned that peace is to take responsibilities and fulfill them; is to have serenity in the most difficult moments of life.
Today I want to hear and speak words that build. I want to have the courage to cry or to smile whenever I feel like doing it...
I want to accept with humbleness that I don’t know everything, but I want to share the little I know.
I like to remember that nature is so exuberant exactly because the differences it shows in its creatures. Each one of us is special, on Earth, and we have the mission that the Divine Creator has entrusted us.
I want to bring: peace, joy and much news."

Greenhouse Effect

The greenhouse effect is when the temperature rises because the sun’s heat and light is trapped in the earth’s atmosphere. This is like when heat is trapped in a car. On a very hot day, the car gets hotter when it is out in the parking lot. This is because the heat and light from the sun can get into the car, by going through the windows, but it can’t get back out. This is what the greenhouse effect does to the earth. The heat and light can get through the atmosphere, but it can’t get out. As a result, the temperature rises.The sun’s heat can get into the car through the windows but is then trapped. This makes what ever the place might be, a greenhouse, a car, a building, or the earth’s atmosphere, hotter. This diagram shows the heat coming into a car as visible light (light you can see) and infrared light (heat). Once the light is inside the car, it is trapped and the heat builds up, just like it does in the earth’s atmosphere.Sometimes the temperature can change in a way that helps us. The greenhouse effect makes the earth appropriate for people to live on. Without it, the earth would be freezing, or on the other hand it would be burning hot. It would be freezing at night because the sun would be down. We would not get the sun’s heat and light to make the night somewhat warm. During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat.
