The star delivered a speech at the TV Choice Awards earlier this month after scooping an award best reality TV show (Blue Planet).
'We have to make a change'
"Our oceans are full of plastic... The Amazon, the lungs of the world is on fire," Packham said.
"As you travel home tonight, you will be breathing toxic air - toxic air that will kill thousands of people in our beloved capital...
"We have to make a change and making changes takes courage.
"Congratulations to I'm A Celebrity Get Me Out Of Here. A request, can you please think about no longer abusing animals on your program?"
Packham then tweeted: "Oh dear, apparently I've been booed (?) at the @TVChoice awards for very politely requesting that @imacelebrity finally stop abusing wildlife on their programmes…I'll be losing sleep over that then."
According to the Metro, ITV addressed criticism over using animals in the show back in 2017, stating: "As a production, I’m A Celebrity complies with all regional and national laws concerning the use of insects, animals, and reptiles.
"We inform the RSPCA NSW of all of our activities on the show and they have an open invitation to attend the site at any time."
