Answer 1The ten plagues are prevented today with science. We have the technology and the know how to prevent most disasters. When water goes back, we have ways of cleaning it. When there are too many insects, we can spray the crops.Answer 2God's Ten Plagues were brought about by God to make a certain statement to the Egyptians and Israelite nations in Egypt. So, it's not that the plagues are currently being prevented (and would naturally occurr without human intervention) but more that God does not have something to prove by bringing back the plagues.
Each of the nine plagues seems to target and overpower an Egyptian god to show that the Lord was the only true God. For example, when God darkness (plague nine) he proves his power over Egypt's chief deity Ra, the sun god.
