Deforestation!

If deforestation continues in the northern hemisphere we are in a lot of trouble. Whether people like it or not we depend greatly on the plants that surround us and if we continue to cut down trees and forests we are losing a huge part of lif's' cycle. The energy that comes from the plants through photosynthesis is what gives life and everything that we do and eat energy. Also, if we get rid of the trees with all of the rain that occurs in the northern hemisphere we are just asking for floods to occur. Also, many living things like animals, insects and bacteria live in these forests and when we cut them down we are killing these living things that actually benefit the world in many ways. Most importantly forests act as a major carbon store because carbon dioxide is taken up from the atmosphere and used to produce the carbohydrates, fats, and proteins that make up the tree. When forests are cleared, and the trees are either burnt or rot, this carbon is released as CO2. CO2 is the major contributor to the greenhouse effect.

Pseudoscience!!

After reading about pseudoscience online I feel that a good example of what I think maybe a pseudoscience would be Astrology. A part of me thinks that it is true science, but then there in another part of me that feels that it is just a belief that many people have. I feel that anyone could say that a certain star or a collection of stars means something or predicts that something is going to happen here on Earth. I feel that Astrology is something that can be easily made up and I find it hard to believe that stars (that are just basically balls of hydrogen) can predict what will happen in our future. Another pseudoscience that I found that I am not too sure of is UFology. An Unidentified Flying Object can be anythng and I don't really see any evidence that shows a UFO that is from an extraterrestrial. Pseudoscience puts a lot of risks on the belief systems in our society. These false beliefs can cause a lot of issues and will make people believe things that are completely false.
