Love our earth

Earth Day began to be celebrated and expanded globally, from 22 April 1990. At that time, around 200 million people from 141 countries around the world were moved to take up the theme of the environment and 'green revolution' on a global scale. Earth Day 1990 also became the starting point for the 1992 Earth Summit in Rio de Janeiro.

For the first time, Earth Day was held on April 22, 1970, when hundreds of thousands of people crowded Fifth Avenue in New York followed by about 1500 colleges and 10,000 schools participating in demonstrations in New York, Washington and San Francisco. Time magazine estimates that about 20 million people took to the streets that day to start a "Green Revolution". This action was the answer to the idea of ​​the environmental movement of 1969 presented by Senator Gaylord Nelson of Wisconsin, USA.

The Earth we live in, is one of the planets in the Solar System, and always revolves around a large star called the Sun. The Earth formed about 4.6 billion years ago from hot gas and dust to a lava ball that then cooled to a temperature of about 5,500 degrees Celsius.

As the Earth's crust is formed, the gas released from within the Earth forms a gas bubble to form a layer called the atmosphere, so that air, clouds and water are formed. Eventually living things appear, starting from the ocean and then moving to the land of plants and animals. Through an ongoing process of continuous evolution, Earth formed as we see it today.

Earth is the only inhabited planet among the other planets in our Solar System called the Milky Way galaxy. In the old system there are nine planets that surround the Sun consisting of: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and Pluto. In recent developments, astronomers agree to classify Pluto as a dwarf planet along with: Ceres, Sedna and 2003 UB313 (Eris), so the number becomes 'twelve planets' (Source:

Humans as one of the living beings who become inhabitants on Earth, is a pioneer for the progress of Earth civilization and intentionally or not at the same time contribute to the process of damage to nature and the environment on Earth. Advancement of science and technology to the internet, so globalized so that the boundaries of space and time increasingly not felt. On the other hand, to meet the needs of his life such as the fulfillment of clothing, food and boards, not infrequently resulting in damage to the environment so that the Earth is getting eroded.

It is estimated that by 2016 the population of the earth will be as many as 8 billion people. Let's see, with a population of so much that the land area is only 149 million km2, there will be many problems that will be faced by the inhabitants of this planet, namely: housing, health, food, environment, employment, land, poverty, war , etc.

Some of the records and facts about the damage occurring on Earth, which is largely due to human activities are as follows:

- Deforestation to be opened for settlement areas, farms and new plantations etc. (About 10,000 years ago natural forests on Earth were estimated at 6.2 billion hectares but now only less than 2 billion hectares)

- Forest tree felling to be used as raw material for building industry, furniture, paper, etc.

- Forest damage due to illegal logging and forest fires

-The natural damage caused by various types of mining (petroleum, coal, gold, tin to sand etc leaving the excavation causing environmental damage like wounds on Earth).

-Lack of biodiversity on Earth as a direct result of forest loss on Earth. According to data from WWF, an international NGO working on biodiversity conservation, every day on the planet 50 to 100 species of living creatures disappear from the face of the earth due to natural changes caused by human activities

-The human activity resulting in the destruction of the ozone layer and the accumulation of greenhouse gases causing global warming and climate change. These gases include: CO2 (generated mostly from petroleum combustion), CFC (used as b
