I am not GREEN!!!

First, i want to say that my commitment with the enviroment is not too much. I respect the enviromental standards like leave thash in dumps and don’t drop it in the street. I think that my best effort is to separate de common trash, like food waste, to the thash coming of papper products, in my house, but i dont carry them to a recycling site, my mom does.
I think that the best place to learn about different practices relationed with the enviroment is Internet, because you can find everything, there are many sites to reed, for example green peace. In these sites, they teach you a lot of practices, like recycling and even they teach you how to build your house with recycled material.
I have to say that i dont know how to use a bike, i have tried, but is imposible, i always finish in the same situation… i fell down and it hurts me, or i crash with parking cars!! Is embarrasing. So i prefer to use the car, the bus and in last cases i walk.
Well, as you would have understand, i dont join any eco-organization, because i dont have time and i prefer to do other things, or help other institution.
I think that in Santiago the government have to implement new politics relationed with the enviroment, because we are breathing a bad air, and this makes us to get ill. No matter the seasson of the year, the disease is always there, in cold and hot days. The air that we breath contains many toxic chemical elements, and it cant happend. Santiago is a city rounded bi hills, so the air cant flow away. I think that government have to reduce cars in the street, and fix buses, because their smoke is black!!!!!

Archaeological News

This new talks about the oldest archaeological discovery made in Great Britain, at Norfolk beach. The site’s name is Happisburg. In this place, a group of archaeologist found different stone tools, like knifes and piercing tools. These tools are very fresh, they are very sharp, and so this would suggest that they are not too far for the original site of deposit.
This discovery, open the idea that early humans were in Great Britain between 840.000 and 950.000 years ago, that is 250.000 older than they believe before.
Maybe these artifacts were leaved by hunter-gatherers and they should border the Thames River, which is dry in our era. These stones should be washed away by the river curse, and finally deposited at Happisburg. The rivers were probably used like travel routes, because most part of the landscape were covered by vegetation, and that limits the free pass.
The early Britons would have live in similar climatic conditions to those of today, maybe the winter is cooler, and they live at the same time as “megafauna” did.
This discovery overturns the idea that early humans don’t life in cool systems, and they prefer a hospitable climate in the Mediterraneo, because before this discovery, was in this zone where the oldest archaeological record was discovered, dated between 1,1 and 1,2 millions years ago.
Maybe the first humans in Great Britain came here crossing a natural land bridge, which connect the actual country with continental Europe. They should have come in a interglacial period, with nice climatic conditions, because after that temperatures dropped too much, and they can’t live there. All of these is because they lived out in the open, but we don´t know if they had clothes, primitive buildings or even if they used the fire.
This is an amazing discovery, so we can’t leave the investigation here, we need to know how our antecessors were, and whet the earth was populated.
