Thousands of dead fish - level 1
This news is about a lake. The lake is in Mexico. It is full of dead fish. People remove 50 tonnes of them. People want to know what’s wrong.
Some people say that nothing is wrong. They say that the fish do this. Others say that there is not enough oxygen in the water.
Why is there not enough oxygen? There are buildings around the lake. They clean dirty water. Maybe, they do something wrong. Maybe, dirty water got into the lake.
Difficult words: remove (to put away), oxygen (O2; the gas which we breathe).
You can read the original story and watch the video in the Level 3 section.
