Scientists still cannot agree on how old our planet is. What we know for sure is that some of the species have existed for thousands years.

Some animals have qualities that we humans do not have. It is both shocking and surprising to know what fauna is capable of. Let us see what the following animals can do to make our world less harmful and friendlier:

1. Dogs

People are trying to invent some sort of treatment that will cure cancer. Nowadays doctors can relatively easily detect and diagnose this dangerous disease. Not it is time for all of us to do our best and prevent it. Medicine keeps developing and new treatment methods are being created. Compare what the situation was like some 30 years ago and you will understand what we are talking about. Nevertheless, there are plenty of tasks left to accomplish. Let us hope that amazing abilities that dogs have will help us resolve health issues. We now know that dogs can sniff out diabetes and even cancer in people. The accuracy of 98% makes us expect that in the nearest future the human race will finally win the fight!

2. Mice

Some rodents are considered pests. There are too few people who would find mice and rats attractive. None of us would be happy to see them in our homes either. On the other hand, mice are another species that can detect and predict when danger is coming up. For example, thanks to incredible senses of smell, rats can ‘smell’ avian flu. The first study was carried out in the USA, Philadelphia, at the Monell Chemical Senses Center. During research scientists managed to find out how the mouse reacts to components and chemicals found in disease laden bird. As we can see, rats as well as mice can be of great use to the human race – their noses are sensitive enough and can be used to help us in many other spheres of life, too.
