In the 1980s, scientists discovered a big hole in the ozone layer. The ozone layer is important because it protects us from harmful ultraviolet (UV) radiation from the Sun. Two chemists found out that chemicals called CFCs were destroying the ozone layer. CFCs were used in many everyday items like refrigerators and spray cans. People all over the world worked together to solve this problem. They signed an agreement called the Montreal Protocol to stop using CFCs. This helped the ozone layer to start healing. Scientists predict that the hole in the ozone layer will disappear by 2070.

Here are some tips for getting the most out of this site.


Beginners: My strategy is to first read the translation while listening to the audio. Then I listen to each sentence individually. After that, I practice saying the vocabulary words out loud. Finally, I listen to the whole text again without reading the translation. I don't try to remember or understand everything. I just let the language sink in as I gain more exposure. (Videos about Comprehensible Input)


Intermediate Learners: To gain some speaking practice, try opening the translation in your native language and then translate it back into the language you're learning. If you encounter any difficulties, you can refer to the transcripts.


Although you may use these lessons for short, intense study sessions, it's important for intermediate learners to engage in extensive listening and reading with simple books, TV shows, and podcasts as soon as possible.
