There is no longer enough natural resources There is no longer enough natural resources to sustain current levels of economic growth. To what extend do you agree or disagree with this stament. Some scientists deem fundamental to respect the maximum burden that the environment can bear. That is to say, the highest amount of population in an area without deteriorating it. Those people see our planet as a spaceship. Mankind has been given a limited amount of petroleum, food, coal, gold, water, etc. The number of human beings and it rate of consumption determine a which rate this living warehouse depletes. With the above view in mind, sending humanitarian aid to third world countries is counter-intuitive and from an economic standpoint would be appallingly inefficient. Thus, It with increase the rate at which natural resources are used up. Nowadays earth sustains around seven billion people. This deed would have been unattainable by using Paleolithic strategies and tools. An outrageous mistake is made when we ignore that humans can create new technologic resources. In other words, as technology evolves new ways of manipulating our surroundings arise increasing the maximum burden. For an instance, since the last century, we generate reliable electricity with nuclear power plants. Moreover, we can now grow food and feed cattle in a much more efficient way than our ancestors did. This important factor is often ruled out of the equation. I strongly believe that the earth is not going to hell in a handbasket. The brink of the cliff is further away in spite of the vertiginous population growth and consumption. To sum up, There are plenty natural resources to nurse todays levels of economic growth, if we know how to manage and exploit them properly.

Modern medicine helps to live a longer life. Do you agree? I strongly disagree. In my view, although modern medicine is convenient, the great leap in human life span has more to do with ensuring the fundamental needs such as shelter and nutrition; and less to do with advanced science. Modern medicine may be helpful to cure lung or skin cancer but it is always way better and easier prevent those terrible sicknesses in the first place. To put it differently, modern medicine is handy for ameliorating quality of live but not for increasing live span itself. For example, improving the sight of our elders with an operation or even numbing the pain of an illness. Above all, individual differences and lifestyle are an important factor to bear in mind. Accordingly, it is easy noticeable a difference between men and women. In conclusion, human begins since prehistory have a limited natural longevity and could potentially pass away aged. But nowadays, due to modern medicine, nutrition, and other health care activities, it is becoming the norm, a right, and not a privilege.

How does the brain processes fear? Imagine that you are strolling through the woods and you suddenly hear a growl and see a big shadow behind some bushes. Before even consciously thinking that you are about to encounter a fierce bear your brain has swiftly conjured up a response to that dilemma. The organ responsible for activating a response to fear is known as the amygdala which centralises this process that we now start to unravel. What we know so far is that the Amygdala is a kind of emergency button that uses priority circuits in the brain that gets pressed when an imminent danger lurks. This is known as Fight-or-flight response and it would prime your body for fighting the bear or to fleeing for your life. Although it an automatic process it not always accurate. Phobias are a good example when the Fight-or-flight response is way over the top.

Why you will promptly become a computer addict A study conducted in the university of Sussex has proven that an effective way of knowing if a computer user is interested on what he is waching is by mesuring the amount of involuntary movements he makes. The 27 participants that conducted the experiment spended some minutes playing enjoyable videogames and then switched directly to reading a tedious monetary European text. While playing a pleasant videgame of there choise the paticipants reduced up to 42% there involuntary movements. This could have a great impact in artificial intelligence because computers could readjust the content you see on screen to catch the eye of the user.
