Today's world we are faced with several important issues in environmental issues. Due to the Earth's balance. This is caused by both natural and important change is the result of human activity. Whether the degradation of natural resources. Environmental pollution Natural disasters such as floods, landslides, including the problem of global climate change (Climate Change), which contribute to global warming (Global Warming) polar ice melt. Sea level rise Severe storms, floods, droughts, the spread of disease vectors and diseases, etc. These problems will cause impact on the environment of the world. Also cause serious effects on human health and property. As well as the economy of global society immeasurably.
Science and environmental organizations in the world today, including NASA (The National Aeronautics and Space Administration), NOAA (National Oceanic and Atmospheric Administration), NSF (National Science Foundation), and the Department of Education and State of the United States. And see how the people live in the present and in the future will be more. On the learning and understanding of the world. Everyone in the world should learn and realize the importance of. Environment, both locally and globally. Especially Youth, the future of the world is the most important factor that will help us to prevent and overcome problems. The emerging sustainability. Began a project GLOBE (Global Learning and Observations to Benefit the Environment) in 2537 and Thailand have joined the project in 2542 by the Institute for the Promotion of Teaching Science and Technology (. National Radio Station.) serves as the coordination and implementation. To encourage students to learn science, world environment through education, research on the nature of the Earth System Science (Earth System Science: ESS) By studying collaboration between students, teachers, scientists. And global community In order to understand the relationship of the various systems of the world aware of the conditions and environmental issues. And shared responsibility as a member of the world to protect and preserve natural resources. And environmentally sustainable
Science. Recognizes the need to encourage students to learn in such environment. Natural world has developed textbooks. This is consistent with the Standards of Learning. Group learning science grade 2 (grade 4-6) curriculum for Basic Education Act 2551 to provide educational and practical activities to learn about the local natural environment. The goal is for students to develop the knowledge and awareness of the relationship between the elements. In environmental systems Including the impact of changes in such elements with a more environmental problems in many aspects.
The development of the natural world in this book. Get better cooperation from faculty experts from the University of educators, scientists, GLOBE science. States, GLOBE teachers and students from the science lab. Would like to thank every one of you this opportunity.
Science. Hoping that the natural world in this book. Will be useful to students and those involved in helping. Teaching about local environmental sciences. More efficient If you have any suggestions to make this textbook more complete, please inform science. Know would appreciate.
