There is strength in numbers. The more people sign petitions and speak up against animal cruelty, the better chances are that those involved will listen:
“TripAdvisor announced they will stop selling tickets to cruel wildlife experiences where tourists have direct physical contact with captive wild animals.
As the world’s largest travel site, the influence TripAdvisor has on the industry is immense and the impact they can have for animals is enormous. This is a significant step towards ending elephant rides, tiger selfies, swimming with dolphins and other forms of cruel tourist entertainment.
The power of the people
Over the past six months, more than 558,000 supporters across the world including around 70,000 Australians called upon TripAdvisor to stop profiting from the sale of tickets to cruel wildlife tourist attractions. And they listened!
In addition to ceasing the sale of tickets we will work with TripAdvisor as they establish an animal education portal on their website to help millions of tourists become aware of the cruelties wild animals face for tourism entertainment.
There is more work to be done
Sadly, however, certain venues that involve animal suffering where direct contact doesn’t occur will still be bookable via TripAdvisor or its Viator brand.”
There is more work to be done, so please keep spreading the word on animal awareness, thank you!

The publicity value of this is huge. Getting them to stop their involvement with zoos and aquaria will be very difficult though x
Yes, thank you for your thoughts. If we keep pushing for these changes they will happen, no matter how hard it will be.
