Animals v/s Humans

In the last week, with my group, we had to do an investigation about two really interesting countries, these were New Zealand and Australia.

We learn so much about the culture, geography and the animals from these countries, but something really rare caught our completely attention... During the investigation we realized that these countries already have a lot of animals! The information was shocking for me because (for example) Australia have more sheep than kangaroos, more kangaroos than cows and more cows than humans! This is a weird fact about the country. 

Even though, for New Zealand the story isn't different because the only 5% of population are humans and the rest (95%) are animals, like koalas and more, and more sheep! This is really crazy, don't you think so? 

Although, the population of animals in these countries are extremely high the percentages are going down with an alarming rate. In fact, the situation with the koalas in Autralia is very disappointing, because in the past they used to be like a million, but now there are not more than 11.000 koalas around the country, we can infer that this is the result of the unconscious people who don't care about the environment or these cute and innocent animals.
