A bit of a different approach on why there are diseases.....

Well, obviously everyone knows about that big, life-threatening diseases, like cancer, multiple sclerosis, aids, diabetes, ALS, and many others...
But why are they there? Well, if you are a religious person you simply can say that god has put them there to test us, or as a science person that it's simply because of genetic errors and existing viruses. 

But....let's move to the animal world and a balanced ecosystem for a moment...

In a balanced system, there are mainly three "species": The plants (Food), The herbivoures and the predators. They all keep each other in check, none is getting dominant over the other.

Now, what happens if suddenly there is so much more food for the herbivoures available? They have more food, less starvation, and now have enough energy and resources to multiply much more, slowly becoming bigger in quantity than the predators are. They, however, either have more food now as well and multiply, and everything is balancing itself out again. 

The same happens when there's not enough food, the herbivoures starve, there are too many predators, so they move away or starve as well, until all is balanced again. 

But sometimes, there are no predators, like for the rabbits in australia, for example. So, what now....? They spread and spread and spread.....well, also because there is plenty of food available for them. 

But what other thing does happen when there are so many and plentiful rabbits sitting "on top of each other"? They start to get sick, diseases spread like wildfire, and it is not easy to contain them. 

Sidenote: Take a look at the "food scandals" there are, like with the swine flu, for example. In nature it can happen too, but usually much more slow and smaller area than through such closed intensive mass animal farmings. 

So back to the rabbits. They multiply so much, so the genes multiply themselv so much as well, eventually making more mistakes for each generation, therefore not only having diseases through virus or bacteria, but genetic ones as well.

Eventually, the animals would deminish again, either because they ate up all their food, new predators arrive, or because of these diseases...Until now, that's basically what can be learnt at school in basic biology lessons, I think.

And in the end, humans are just animals too...but are there much predators? I don't think so. Is there enough food and water? Barely, and the mass productions can cause other problems. And like we all know, the human population keeps on growing and growing....Picture a cancer in the body, like some say.

So, that's where diseases come in, either by bad lifestyle, genes, messing with the environment, or whatever....all as a try to keep humanity in check and balanced in the world wide ecoystem. If you find a cure for one, another will pop tiny tiny little invisible predators ;) 

Another sidenote: That's why I liked that image of that article so much, that says that T-cells are hunting like tiny animals: T-Cells hunt parasites like predators 

Well, but back again into the animal world: do all animals that have diseases die? Not really, or else there'd be much fewer animals than there are. And not all humans that have diseases die from them either, or at least not for a certain period of time.

But there is also something I remember well from my biology lessons: If a species is endangered because of predators, they have more children for the next generation, to even out the ones that will die because of said predators or because of bad/ harsh environment. This would explain very well why we in the "western world" have fewer and fewer children, while those in the "3rd world" have so many! If you look on the scale of the whole world and population however, it is increasing with speed, in every generation there are more children born, so what does that tell us........? little hypothesis would be: "Humanity is a species that spreads too much and has no predators, therefore to keep a world wide balanced ecosystem, there is the need for other kind of "predators", to try to diminish them and keep them in check." 
And also.....
"Somehow, in some way or other, humanity itself is almost like an endangered species, but mainly because of what they do to each other and to the world...."

Well, I am sure not everyone likes that way of thinking, nor can I prove it as facts, nor do I try to, I simply like to connect all the things I know, and also "think outside the box" ....

If this makes you think or consider this up to yourself. It certainly never would be teached like this at school, because, after all, since when are humans like animals? :)
