People are Changing Sharks
personally, I do not fear sharks nor am I protective of them. However, they should be left alone to live their lives their way. Ecotourism is restricting their freedom to roam. Any country that can do it, is doing it to bring in the tourist dollars.
More than eight billion people a year go seeking experiences in supposedly protected areas, which are commercialized. This is like the whole population of the planet trampling over pristine environments, because that is exactly what a high number of visitors do.
Crazy tourists actually swim with sharks. Let's face it, Man is dinner to sharks. This is the rule of things. The dangerous creatures come very close to swimmers. They are becoming domesticated. Note, many dog owners have been attacked by their pet! More, complete strangers have been mauled.
Tourists are affecting the natural selection of sharks. To attract them to tourist boats they are fed. Consequently, they have a better chance of survival. The man eaters are being selected for traits like choosing to be close to people!

Animal Biodiversity is the Highest Ever
Despite extinctions the number of animal types in the world is at an all-time high. This is due to a proliferation over the last 200 million years. It seems as time goes on the number of species increases. This seems to be a law on this planet and maybe the universe.
There are indications that humans could be changing this by causing extinctions. However, it will be a long time before the variation of species declines significantly. With the poles melting a tipping point could be reached where even humans are under threat of disappearing. This is just a theory at this time. Perhaps, changing the way we live will make things better for all creatures.
Human knowledge is going on a pace. There are new discoveries minute to minute. Indeed, it is difficult for specialists to keep up with all the reading that is necessary. Even general practitioners say there are not enough hours in the day to keep abreast of the latest breakthroughs.
