Many people say that life in our world today is better than it was 50 years ago but I don’t agree with them.
Currently, Thailand's forests have been destroyed about one hundred square kilometers or 66 million hectares, accounting for 1 in 5 of the country. If you go back 50 years ago when the resources are abundant than today.
Second, congestion is the increase of the population in the country, which affect the natural resources. For example they build housing which to encroach upon the forest area. It also built industrial and releasing the waste which cause air pollution. But in the past, the population of the country is not overwhelming ,and the need to use resources in a lower rate than the present.
