What can you see in the photo?

I see someone wearing the face mark and he is working in this picture. This picture can express many meanings.

First of all, I see air pollution and more people work form home. People make the air pollution. There are various causes of air pollution for example the burning of car engine, agricultural activities, waste in landfills and exhaust from factories and industries.

Then, the air pollution returns to affect the human’s health. Air pollution can also cause headaches, nausea, heart disease and lung cancer.

Finally, We should do something to reduce the air pollution and save the world. We have to use the clean energy.
