Earth Day ~ A day to celebrate earth

By Student Nopthanit Suesat from Thailand

Earth day helps celebrate Earth as she is the only planet in our solar system teeming with people, plants and animals. Earth provides all the necessary elements for human, plant and animal life (e.g. air, water, land and mineral). Most people celebrate Earth day on April 22nd each year.

When we talk about air, we meant the Atmosphere. The Atmosphere protects us from the optimal light and heat from the sun. It cuts off ultra-violet and infra-red rays. We have two types of water that is ice and liquid water. The liquid water travel around the world and we use for drinking and irrigation of crops. Land and soil have mineral inside, we use it grow crops, vegetables and plants.

 Global warming is the rising average temperature of Earth’s atmosphere and oceans.  Most of it is caused by human activities such as smoke from the industrial activity dumping into lakes and rivers, military industrial waste and exhaust from cars and airplanes which are the main problems.  The Aviation industry causes 3.5 percent of global temperature. Other causes which increase Global warming are deforestation and use of plastics.

 We can do many different things to help our Earth. For example:

Reduce electricity usage inside our house

Switch to energy efficient lighting. You should replace traditional bulbs with compact fluorescent bulbs.
Improve efficiency of appliance at home, it is very easy when we buy electrical devices, we should look for the energy saving symbol.
Reduce energy needed for heating and cooling, for instance, wearing warm clothes instead of turning on the heater.

2.    Conserve water inside our house

We should check for leaky taps and not let water running while we were brushing teeth or shaving.

3.    Change our eating habits

We should eat more vegetarian foods and fresh foods because they require less energy to cook.

          The name and concept of earth day was pioneered by John McConnell in 1969 at UNESCO conference. Senator Gaylord Nelson founded Earth day in the United States. Earth day was first celebrated on April 22, 1970. Earth day 2007 was one of the largest to date, with an estimated 1 billion people and over 17000 organizations participating in the activities.
