Today I'm gonna talk about some characteristics from the dogs for example about the hearing, smell and vision.
The dogs have a highly developed sense of smell and hearing, the smell being the main sensory organ. There are approximately 800 breeds, that is to say, more than any other animal, which vary significantly in size, appearance and temperament, they present a variety of colors and types of hair according to the breed of dog. They have a great relationship with humans, who are:  for pets, guard animals, working dogs, hunting dogs,   or guide dogs for example. It is one of the most popular pet animals, probably second only to the cat.
About the vision; the dog's vision is developed for hunting, they don't have a great visual acuity of details, but have excellent perception of movement. they have excellent night vision because to the use a reflective screen inside the eye. They also have a color vision equivalent to red-green color blindness in humans
It has been shown that dogs are able to distinguish your owner from others persons at distances of more than a mile.
About the hearing; they detects very low sounds compared to humans, also have a degree of ear mobility which allows them to quickly determine the exact source of a sound.
Also, they can locate the source of a sound a lot faster than a human and detect sounds from a distance four times greater than humans.
About the smell, the dog brain is dominated by a mainly olfactory crust. The dogs have between 125 and 220 million olfactory cells. Dogs can distinguish odors at much lower concentrations than the humans.
I love dogs.

How green are you?

I think these last years people have learned more about how to live and take advantage of our nature and environment, this is related to the increase in pollution in our society and how people have chosen to relate to the greener world, and cleaner and pure environment. There are many people who have bypassed the city to start a life in the countryside and enjoy the benefits of this. 
In my case and that of my family, we have incorporated the theme of recycling, but, not in all, it is an issue that we lack even resolve. We recycle everything that is plastic, cardboard and glass. In the place where I live there are lots of people occupying these as materials and other things, so, we give this for them. 
Unfortunately, where I live is hard to go elsewhere if it isn't in a car, for example go to santiago center, the locomotion isn't the best and walk or by bike would be impossible, but I use my bike in the moments when I can. 
I supported a type of organization that took place in my commune, is about  the subject previously said, related to recycling and how the other persons use our garbage to others things. I think it's necessary to create recycling habits in our lives, for that gradually it can be a normal thing in our life and like this, we can help to our society to see the environment differently. 
I think that there're many things I need to do and sometimes by a matter of comfort, It's forget, but I've tried to reduce the carbon footprint, trying to avoid the misuse of electrical energy, avoiding a little the use of vehicle, trying to eat more fruit and avoid some meat, for example. 
In our society is necessary more culture about our environment, is necessary a awareness of our environment and will power from people.
