It is very possible for Zoos, safari parks, aquariums and farm attractions to open safely with social distancing regulations, yet they have been told they must stay closed indefinitely. I think they should be allowed to open their gates to the public if they can prove that they can operate safely.

There are countless animal attractions which are on the brink of permanent closure. The government has given 40million pounds to them and told them to stay closed indefinitely. However, zoos eg Chester zoo, need in excess of half a million pounds a month to keep going and keep animals in a decent standard of Living. So between al of the attractions under forced closure 40 million won’t stretch far. It’s not just a matter of keeping them from permanent closure, it’s a matter of animal welfare.
