2018 was a year in which the threats facing our planet—from plastic pollution to climate change―became impossible to ignore. As scientists and journalists continued to sound the alarm, ordinary people stepped up to do something about it.

So if you are looking for a New Year's resolution for 2019, why not add saving the earth to the list? To get you inspired, the EcoWatch staff is sharing successful green changes we made to our lives last year, as well as the improvements we plan to make in the year to come.
