Passage 2
Forty years ago no one was concerned about the health of the ocean, in spite of the fact that many fisheries were being over harvested, toxic wastes were being dumped in the sea, and developers were beginning to seriously disrupt coastlines. In those days, the magnitude of the problems was small, even though it was obvious that if the trends continued people would face severe economic and personal hardship in the future. People just didn’t understand, nor did they care. Unfortunately many of our concerns were realized, but the situation could have been much worse had we, and others, not taken action to inform people about the ocean and the need to protect it.
During our campaign to share the wonders of the sea and alert the public about the need to protect it, we have used every medium available——personal appearances, the printed word, and television. Now there is a new medium that is even more effective than its predecessors. Th
A. the computer is as smart as human beings

C. human beings can interact with the computer and do what they want at their will
