humans did not exist‚ extinction occurred due to natural causes. On this present time however‚ extinction of species are threatened by humans’ existence. Humans are the only moral agent; in which‚ it has the intellectual capacity that animals and plants do not have. Thus‚ humans are powerful and dominate over any species. Many practices that humans do such as: tree logging‚ environment pollution‚ exploitation of animals and others has led to many species being endangered to extinction. Thus‚ humans

means it can easily ionise substances‚ Many compounds‚ whether ionic‚ polar or covalent will dissolve in it‚ therefore more reactions take place while in solution with water. Often in organisms substances must be in solution and water is the solvent. Plants can only obtain mineral salts in solution and human digestion will only dissolve soluble foods‚ meaning large starch molecules must be broken down into soluble sugars. Also many organisms living in water spend most of their time underwater‚ yet they

burning” of rainforests has to stop. The deforestation of our rainforests is effecting our environment and us more than you may think. We get the oxygen we need from trees‚ forests protect us from Carbon Dioxide‚ and forests protect most of Earth’s plants and animals. We need trees to breathe and rainforests to protect us from harsh things that we emit from our bodies. Many rainforests help and protect us. “More than 20% of the world’s oxygen comes from the Amazon” (Fraser 2)‚ the Amazon is an immense

extreme that is affecting plant and animal survival‚ thus damaging infrastructure. Dryland salinity is caused when the rising water-table surfaces natural salts in the soil. The salt remains in the soil and becomes increasingly concentrated as the water evaporates or is used by plants (Australian Government‚ 2001). One of the main causes for rising water-tables is the removal of the native Australian vegetation. They have deeper roots and use more water than the crop plants that are replacing them

useless in the beginning. I started out just picking weeds and moving plants from one side to the other. Progressively I learned how to trim the plants‚ how to remove roots more efficiently‚ dig better holes to put plants in‚ not to care about bugs as much and learned names of plants and flowers that I’ve never heard of before. This is all thanks to Marie. She assisted in extending my knowledge and helping guide me to improve my plant caring skills. At the start‚ I felt that taking care of the garden

We can prevent spreading it by good hygiene. However‚ if the spreading cannot be controlled‚ there are some other ways of treatment. Herbal plants play an important role in traditional healing of fungal infection. The researcher proposed Suob-kabayo leaves as treatment for athlete’s foot. According to Bacon‚ distilled from the plant a greenish‚ volatile oil‚ with a powerful menthol odor‚ investigation proved that menthol is the principal constituent of this oil. Santos and Valenzuela
