How trees talk to each other?

  Trees in a forest are divided into hub trees-the oldest and the tallest ones and smaller trees. Those which are taller have greater access to sunlight and therefore produce more sugar that they need. Because of that fungi receive it and give in exchange their nutrients. Through the fungi system smaller trees are connected with the hub trees and they can use it to send warning signals if a tree is infected or to exchange nutrients. I think this knowledge is valuable because it shows how the oldest trees are important in the ecosystem.

Reflection 5

Every time I am in a modern art gallery I meet at least one person who don't know how they got in that place. They feel uncomfortable with the fact that they don't get artist intention and simply don't understand the meanings of these works of art. In the past artists had to follow specific rules which were created through the years. Basically they used to copy famoust art gurus all the time and just changed some details but the idea and topic of the painting was the same. It is also caused by the fact that old paintings are all very realistic so we know what are we looking at but from the time that impressionism appeared in the art world it started to be more complicated. I think that we should be more educated about modern art to be able to interprate it without so much effort. We should also have more guides in museum and art galleries who can tell us more about works of art.

Reflection 6

  Recently, I've watched quite an interesting Polish movie "Short film about killing". In my opinion it showed in a simple way how people perceive death or murder due to the person who committed the crime and the way of doing it. The main plot was about a young man who brutally killed a taxi driver. Firstly, I felt anger because all in the entire driver was an innocent man, the murderer didn't know him so he didn't seem to have a reason to commit that crime. I thought so until the next scenes showed that the man actually wanted to steal a car to go on a trip with his girlfriend. Of course this is not an excuse for his behaviour but at least it clears a little his motives. In the end the criminal confessed to his lawyer about his sad past, the fact that his friend accidently killed his sister. It seemed like in his opinion this accident was the reason why he changed and committed the crime.  Finally, there is a scene of the murderer execution and this was what ...

Living off the land of Hawaii

  Nowadays we're dependent on big industries and I think that it's a problem. Usually we have to buy food that shops provides us but it's getting less healthy because it's mass grown and polluted by dangerous chemicals. Whereas, if it's organic, it's usually more expensive. This video shows that there're still people who provides food for themselves by hunting or growing it. For some it may seem primitive but I think that it's better for the environment, healthier for us and also cheapier. words: remote place, descendant, self-sufficiency People usually don't live in remote areas. Children aren't self-suffient because they're dependent on their parents. After king's death his descendant inherits the crown. . https://www.youtube.com/watch?v=jJXEepvG6Hc&pbjreload=10
