Whether you trust the weather forecast and why?

The most of 4 seasons i like winter. Because at the winter we have holidays, we are celebrating Christmas and New Year. 

The Earths climate has changed greatly. We have a pollutions, a lot of rubish of factories and it can be dangerous for animals.

I trust in the weather forecast because it helps to chose clother for a day and daily activities.
