Changing Atmosphere

Every year during this season, weather becomes warmer. Open burning happens everywhere, from cities, villages to farms. It could be massive open burning domestically and in neighboring county that often causing hazy atmosphere for months. However it would also depend on the wind blowing direction. The hazy weather started since few weeks ago but it turns clear on and off. Just like this morning, the sun shining directly onto the ground. A bright reflection from glass window is seen. However, the sky become blur again in the afternoon. I am wondering when will this bad practice stopped and claim our fresh air back.
