Nevertheless, that's what we had been feeding him, It said on the packets that it was “scientifically prepared,” but now we realize it was prepared economically. While there are good reasons for pets to eat waste from human food production, ,it is unwise to feed them types of waste they would never naturally eat, and which actually make them fat and tob avn 20 unhealthy.

NG A. Circle the causes and underline the effects in this text. ND CTS Not all reefs begin naturally. For example, an ocean current may encounter a man-made object, like a sunken ship. As a result, the water around the ship may become rich with tiny animals called plankton. A lot of small fish gather there to feed on the plankton. Consequently, larger animals are attracted to the ship. Because the ship has many little openings, many creatures also have a place to hide. In time, the ship becomes covered in polyps. As a result, it no longer looks like a ship at all.
