ENG3U1- Persuasive Essay What if you were told that humans are destroying the world we live in‚ and that this earth could slowly disappear in front of our eyes? How would you react‚ what would you do to stop that? Since humans occupy the highest position on the biological hierarchy we are responsible to tend to the plants‚ and animals beneath us‚ because if we do not it will in turn affect all human life. The negative impact from not having a sustainable biodiversity is; we will not be able to

The closest living relative to humans are primates. The study of primates and their behaviors is primatology. Primatology provides a better understanding of the many aspects of the research‚ preservation and conservation of primates. The field of primatology has been fortunate to have several outstanding scientists‚ among them Jane Goodall‚ the late Dian Fossey and Birute Galdikas. Each of them has accomplished considerable works documenting and interpreting the lives of chimpanzees‚ gorillas

Have you ever thought about how many animals there were back then? We have been researching the 10 geological time periods and we found some interesting things. Like for example‚ there were many species of animals‚ plant‚ and fungi. There is one big question‚ has the amount of species gone up or down over time? Yes‚ I believe that the number of animals living on earth has increased over time‚ i believe this because scientist are finding new species of some sort‚ There is a lot of land that could

or taxonomically. An area is considered biologically diverse when there are variety of interactions among the different organisms living there. Tropical rainforests have a notably high diversity and are able to support a wide range of invertebrates‚ birds and mammals. In areas surrounding the equator the largest amount of tropical rainforests are found (UNEP‚ 2013) and is considered especially diverse as there is a continuous supply of recycling nutrients‚ variety in primary producers‚ steady

Coral Bleaching Coral reefs deliver ecosystem services to tourism‚ fisheries and shoreline protection and often called “rainforests of the sea”. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Coral reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. However‚ coral reefs are fragile ecosystems‚ partly because they are very sensitive to water temperature. They are under threat from climate change‚ oceanic acidification‚ blast

and the Loss of Natural Resources Natural resources including soil‚ water‚ forest‚ mineral and biodiversity have been repeatedly destroyed around the world by humans. “Since 1970‚ over 600‚000 square kilometers (232‚000 square miles) of Amazon rainforest have been destroyed” (Butler‚ 2011). The FAO (Food and Agriculture Organization) estimated that “soil erosion carries away a volume of soil equivalent to one metre deep over 200‚000 hectares every year in the Philippines.” In Asia‚ where water has
