Soil losses in Chile

http://camposureno.wordpress.com/2010/06/24/estudio-revela-la-verdad-de-la-erosion-en-chile/

Before 2010, there were only little information about soil quality; actually the last public report was from 1979. But in the last years, the government has the idea of put this topic as an important agricultural problem.

Corfo gave 900 millions of pesos for improve the actual information that includes all the soils of the country. These is public since 2010.

This report shows that the biggest losses of soil (erosion) in Chile are in arid and semiarid areas between Arica and Bio-Bio region. And also talks about no apparent erosion, which is soils with vegetation where it is not possible quantify the soil loss.

They made categories of classification: moderate, sever and very severe. These are necessary on technical studies of field qualification.

In particular, in the north of Chile, the erosion is higher than 80%, however, many of this areas haven’t human influences. But, if we go to the south (III or IV region) there is more human influence.

So, the target of this project is separate soils where natural erosion predominant from anthropic erosion.

I think that this report it could be very important. In these times, the people use the soil without knowing how to preserve. For example we can see fruit trees planted in the direction of the hillslope and there is not concern about the soil loss that this cause. It is necessary show to the agronomist and foresters how to use properly the soil and conserve for the future.

Mother Nature Teaching

Jane starts talking about a tribe in Ecuador. Is a community that’s fighting to maintain their unpolluted way of live, but still realized that they can use and learn a few things from the “white man” to improve the way they live without harming it. But her real area of expertise is the Chimpazee. She states the change in the research area of the animals because of the improvement in the technology. How Ai, the most intelligence chimpanzee in the world can now manipulate a computer, even faster than most of the humans, and do it for almost no reward. Then demonstrates the thin line that separate us from big brain mammals, because they can even make use of tools, and behave emotionally and physically like humans. And this show that we aren’t the only living being that can do this kind of things, opening our eyes and having more respect for the other animals with whom we share this world. And then she shows us the awful truth that we decide to avoid. We are killing them all, and not only the animals, but the clean civilizations like the one she mentioned at the beginning. And how we should be doing the exact opposite of it, learning more of the Mother Nature and the animals. She finish telling us that the real answer is in us, we can act towards a clean world right now, and not the politicians and economists, etc. I find this conference really important and that this should be the things teach to us on an early stage of our lives, not how to make more money to follow a false and contaminated way of life.

Leather and meat without killing animals

In the video Andras talks about the possibility of made grow animal products like meet or leather instead keep killing or making suffer the animals. He says that in this times is not a crazy idea think like it was several years ago. Actually maybe in the future we look back on today and say that the things that we are doing now to produce meet or clothes are crazy.

In these days, livestock is one of the largest users of land, fresh water and the biggest producers of greenhouse gases. The biofabrications can be used to grow biological products, actually in medicine is already using to create organs, so it is not unthinkable do it with animal products

He explains the procedure that it takes to make leather and also, says a few advantages of using this instead leather from the animals. We could control some properties of the original leather tissues, for example, the leather made throw biofabrication doesn’t have hair on it so this it would means less work to process the final product.

I think that the video is really interesting, I’m not sure if this is easily doable, but if it is, will be a really nice thing for the animals and the people also.

New Report of Climate Change

The article talks about an investigation made for the IPCC that strength certainty of climate change. Is the first report from 4 that they going to made this year and represent the opinion of hundreds of scientists.

This report claims that global warming is causing by humans and also it comes to be worst if greenhouse gas levels don’t stop growing. Is more focused in things that actually happening now (ice is melting faster, the ocean is becoming more acidic and weather patterns are chancing) instead things that it comes to happened.

It is not very different from the report that was made in 2007. But now, there is a subject that gained more attention as a potential way to directing the climate change, and this is the geoengineering. As an example from measures to stop global warming, they say that injecting particles into the upper atmosphere to reflect sunlight back into the space to stop their pass to the earth.

An important conclusion of this article is the evidence for an increases frequency of heat waves in many parts of the world. However, not all types of extreme events are increasing because of climate change, but exist an effect of global warming in people and ecosystems.
