Could you please give us(me) the data then
I have never demanded data
As an aside, it is inevitable that reopening places where the public will congregate in some form or another (and I do understand that some (many) zoos do not fulfil these criteria), will cause a rise in cases, because the number of individuals that people will come into contact with will increase, inevitably. There is not data, or proof, or figures, or evidence, or link needed to know that for certain.
There are only two things that can stop numbers from rising once people start coming into contact increasingly, and those things are a vaccine and mass testing. A vaccine is not a possible option as of yet, and both the UK and US government seem to be finding it hard to get their heads around the concept of testing, so the only conclusion that can possibly be derived from this is that numbers of cases will rise.
Mathematically, there is a chance, an infinitesimally small chance though, that it will not cause an increase, and that that increase in contact between people will result in no, or very few, cases. However, the probability of this occurring is in the magnitude of one in tens of billions. Furthermore, as people come into contact more an more, they will return to normal habits more and more, washing hands less, doing away with uncomfortable/inconvenient masks etc.
It is impossible that the situation will ameliorate as places open up. Of course, if it were just zoos to open up, the numbers would hardly rise, but the truth is, the government would never do that and zoos rely on other services to bring in visitors and to function. You would know that better than anyone on this forum.
