Blog #8 What I Learned / Questions

Well after doing some of these recent blogs I've been learning about how this world we live in has so many biomes. You look at how much space a certain biome takes up, and what kind of characteristics it has, like what type of animals live in those areas. Also how certain plants live in specific biomes, and cant be found anywhere else. Also how the biomes were formed so many yeas ago. It just really makes you think about nature, and what it has to brign to the future. But our human race tends to be blind to the beauty of these biomes, and we decide that we need it for more useless space.

Blog #6 Which level of a food pyramid is the most important?

Well i believe that every single level of the food pyramid is very important, but at the same time i think that fruit is a little more important than the rest.

Blog #5 There have been 5 major extinction events throughout history, are humans impacting the 6th? Why or why not?

 Well it is said that 3 species are getting extinct every hour. Which is a lot.... they say that humans could be tha cause for he 6th extinction but not completely our fault. It could also be caused by natural causes such as .....transformation of the landscape ...over exploitation of species....pollution.... the introduction of alien species. But i guess you can say that humans are part of the reason why.
