In the first video, it seems that the decrease of plowing and the use herbicides has helped lower erosion. My first thought, was that the use of herbicides was more harmful to the environment then the use of plows. However, after listening to this video, it seems that the use of the tractors and plows are more helpful to the environment . According to Graham Brookes, in 2004 there was ten billion kilograms less co2 within the atmosphere. He said it is the equivalent of taking twenty percent of the cars in the United Kingdom off the road for a year. That is a very large portion of co2 that has not been released into the air.
In the second video, I did liked how there was a demonstration used to describe how rain water filters through grass, corn residue and soil. It makes sense to me to stop soil erosion by the use of grass and the left over crop residue on the surface of the soil because it helps produces better filtered water.
In the third video, when the man states what gardeners should look for in their plants; it seems quite self explanatory. Although, his steps seemed be very useful.
In the fourth video, I would need to research more about the situation to really decide what I think is best. I believe that it is fine that researchers are trying to find ways to make more crops for people in developing countries. I personally think, in the years to come we will find out that the genetically engineered crops are more harmful then useful.
