Saya mau tau Kesan ekologi dari Frekuensi teramat rendah. Jelaskan dalam bahasa melayu

There have been some concerns over the possible ecological impact of ELF signals. In 1984 a federal judge halted construction requiring more environmental dan health studies. This judgment was overruled by a federal appeals court on the basis that the US Navy claimed to have spent over 25 million dollars studying the effects of the electromagnetic fields with results indicating that they were similar to the effect produced by standard power distribution lines. The judgment was not accepted by everyone dan during the time ELF was in use, some Wisconsin politicians such as Senators Herb Kohl, Russ Feingold dan Congressman Dave Obey called for its closure. Similar concerns have in the past been raised about electromagnetic radiation dan health.
