Causes of environmental problems. Environment and natural resources are destroyed day by day, but so on down by the environment and natural resources are destroyed.
And the loss of three ways (Ratee Para, 1997).
1. Human.
2. Animals and various diseases.
3. Natural phenomena.
The loss due to human factors are most important. Due to the following reasons.
1. The increase of population Currently, the average increase in global population is increasing and the increasing population means more demand for use Resources in different stage of life is increased by (Supoj Saengmanee, 2546) cause different effects such as the increase of agricultural land in agriculture. Invasion and destruction of forests. Causing loss of balance in nature. Moreover, the need to use G other resources such as water, minerals, increased energy, air from the past to the present revealed that the growth rate of the population. Each year. Major cause of the increased use of resources and the number. The limited existing resources decreased rapidly And the resulting shortage of resources and environmental pollution by the different.
2. The expansion of the city. Growth of the community or city. Causes a change in the natural environment because of different growth. City quickly can cause lack of planning and planning to advance the cause other problems and the growth of cities usually the industry's growth occurs with And in various steps of the industry if the lack of planning. And good control will result in many different environment.
3. Using advanced technologies Modern technologies used in the manufacturing of agriculture. By using various chemicals such as fertilizers and pesticides resulting in residues. These compounds in the soil. And may expand to various sources, water resources and ecosystems and the effects of different combined to accumulate. In food and fiber industry. Substances used in production processes and substances resulting from the manufacturing process, such as lead, mercury
Arsenic is harmful to health as a process of elimination and the residue (Residuals) to put an end to the difficult And will affect many different follow.
4. To build various buildings. Creating a reservoir dam road is considered a major cause of the primary resources. Such as forest damage soil, water, wildlife can be prejudice Ruby too. The man into the remaining forest easier. Due to the easy destruction is occurring continuously. Once degraded forest or away Residence of animals were destroyed. Hunting opportunities have been greater. Some animals find food Is also difficult. Eventually extinct etc.
5. Sports. Most of the wildlife resource, such as shooting, fishing and bird hunting, etc. If done for the sport that had no real problems with much destruction of natural resources. But when the competition for the number recorded. Size serious and advanced weapons will be used more. Wildlife would have to be part of the body or part of the food. Or appliance only. The rest is left in the forest, which acts not worth the loss of life and heredity of animals.
6. The war. Cause the urge to use existing resources more. Mineral resources used to manufacture weapons and tools which finally destroyed. Sometimes, to expedite drilling for oil sales. Then money to purchase modern weapons. High destruction efficiency. To fight each other. Effects of war is to lose both in human resources or other resources, such as bombardment. Destruction of human life and resources, Natural resource damage wells. Of Iraq in 1993. losing resources. Which take millions of years to the birth and unfortunately also cause damage to the environment the world over.
7. Unawareness or ignorance. Many times people do not know because of our environment to cause and effect Lack of understanding of the correct information. Allow us access. And related to environmental differences. While environmental conservation thinking in terms of natural ecosystems. Forestry and Wildlife. But the industry to think about the material factors of production as an economist would think the cost of resources required for cost-effective. Farmers are reminded rain Tourism sector think money Farming is not correct, etc. Farmers also lack an understanding of society. Environmental characteristics and the relationship of things that when damage to any one of them will have the same effect and Each other, sometimes forgotten that Fun for a while is destroying their spontaneity and beauty of the place.
