altered and modified‚ but these tend to happen at a gradual pace. This allows most species to adapt to the changing environment‚ where only a slight impact may take place. However‚ when changes occur at a fast pace‚ there is little or no time for an individual species to react and adjust to the new circumstances. This cause disastrous results‚ and for this reason‚ rapid habitat loss is the primary cause of species becoming endangered. Nearly every region of earth has been affected by human activity

Biodiversity has been on the decline over the past century and the background rate has been mostly accelerated by the humans. Considerable damage has already been done. Possible solutions have been discussed and categorising species according to how in danger they are is one of those solutions. Below are some of the threatened organisms in different continents around the world. TABLE OF CONTENTS Africa Mammals Birds Reptiles Amphibians Fishes Asia Mammals Birds Reptiles

Shannon Angus Mrs. Cumbee January 9‚ 2013 Foreign Invaders Invasive species are groups of organisms that are unnaturally occurring to an area. When introduced‚ they can cause economic and physical harm to humans and ecosystems. The importing‚ legally and illegally‚ of invasive species into our society is not only harmful to our population and our ecosystem but also the population of plants and animals in their indigenous homeland. To continue‚ the smuggling of plants and animals into new

1. Decodable Text * There are five levels of decodable text‚ ranging from highly decodable to minimally decodable. Highly decodable books use one-syllable and one-vowel-sound words‚ such as “cat‚” “fun” or “sit.” These might also use some short sight words‚ such as “a‚” “an” and “the.” Very decodable text still uses simple words‚ but those words may now have an extra letter or use blends that the students are learning in class‚ such as “this‚” “such” or “that.” Decodable text adds more of
