Invasive species often desecrate ecosystems, wreaking havoc in crucial, distinctive ecosystems such as the Mojave Desert, known for its exclusive wildlife. Not much is done about the many types of invasive plants that plague the Mojave Desert and the number of known invasive species of plants that affect the Mojave Desert is over one hundred (“Invasive Plants”). Invasive species of plants create many diverse issues in the ecosystem of the Mojave Desert such as being incompatible with local animal species, outcompeting local vegetation, and providing fuel for fires, increasing their frequency, that rage across the landscape, damaging the fragile desert ecosystem. Invasive vegetation is often discordant with local wildlife.
For my ELA performance task I read both Milkweed by Jerry Spinelli and The Diary of Anne Frank(play) by Frances Goodrich and Albert Hackett. Milkweed is about a boy named Misha Pilsudski who lives in the ghetto on the street and has no identity including name. As time goes on he gets a name and finds a new family who welcomes him into their home. All the while he is trying to learn about his surroundings, as he is unsure whether he is a Gypsy or a Jew. He attempts to make life as happy as possible and fix things that he doesn’t realized cannot be fixed. For my performance task I have chosen to show two things that are different about these books and one thing that is similar.
I am going to identify the plants in each area and count them. I will
Invasive species as a whole have become a nuisance to many habitats and ecosystems around the world. What defines an invasive species is the following. It must be a species that is foreign to the habitat it resides in, have no natural predators which allow it to reproduce in such a rapid manner, and out compete native animals of food and shelter (Rosenthal 2011). These characteristics are what create such high populations of these invasive species in various habitats around the globe.
The current El Segundo Hyperion plant is 144 acres of glass, concrete, and pipe. It is the end of the road for sewage from over 6,000 miles of sewer system maintained by the city of Los Angeles. (NORS S-1) The Hyperion plant is the environment’s best and last line of defense against the over 500 million gallons of wastewater produced in the area a day. The sheer volume of this waste most of which is being released into the Santa Monica Bay must be having some impact upon the environment. The purpose of this paper is to investigate the workings of the plant and its impact upon the surrounding environment.
The book “Milkweed” by Jerry Spinelli tells a story about a boy who survived the horrible days of World War 2. He struggles every single day to find his identity and what is happening in the world. The book “Milkweed” itself shows many signs of survival. Both literally, and figuratively. This novel describes what the Jews did to survive and how they survived. The theme of survival is represented by different objects. The author, Spinelli, uses many literary elements to describe and support the theme of survival. The main three are: setting (where and what time), symbols such as the plant Milkweed that represents a new hope, and conflicts (what is the fight/fighting in the story).
Invasive species are non-native organisms that occupy habitats and disrupt the natural ecological cycles of the habitat. They threaten the biodiversity of an ecosystem and are biological pollutants Invasive species introduced into new habitats usually maximize their reproduction in their new home and crowd out native species. Their lack of natural predators in their new community allow for a proliferation in growth and expansion as a result of their abundant food supply. Once they are established, invasive species can rarely be eliminated because their new habitat is favorable for their survival.
Should exotic snakes or other large reptiles be allowed as pets in Florida? Right now these escaped/released feral reptiles create an estimated $120 billion in environmental damage each year according to David Steen on Slates Animal Blog.
Nonnative species can also be called alien, exotic, or nonindigenous. Their presence is due to humans dispersing them to other locations beside their native habitat, or by humans creating environmental conditions that allow their growth. When nonnative species begin to take over a new habitat and displace native species, they are then termed an invasive species. Nonnative invasive species are one of the biggest threats to ecosystems in North America (Cox, 1999) because they are able to have an impact on many levels, including ecosystems, communities, and populations (Cushman, Tierney, & Hinds, 2004).
Invasive species are organisms that harm a new environment that they are not native to. Many invasive species like Eurasian milfoil are easily able to reproduce and can do so fast. Due to this, the limited space in a body of water or area of land is quickly taken over by the invasive species so other native plants face the risk of death or even extinction. Overall, these invasive species can do great harm to an ecosystem or an economy, causing problems that are destructive to numerous organisms.
Humans are responsible for almost all of the invasive plant and animal problems. Many of our problem invasives were (and often still are) planted as landscape plants in New Jersey. These include: Norway Maple, Japanese Barberry, Asian Bittersweet, English Ivy, Mimosa, Wisteria, Japanese Honeysuckle, Bugleweed, Bamboo, Day Lily, Purple Loosestrife, Tansy, and Dame's

Man has used hallucinogenic plants for thousands of years, probably since he began gathering plants for food. The hallucinogens have continued to receive the attention of civilized man through the ages. Recently, we have gone through a period during which sophisticated Western society has "discovered" hallucinogens, and some sectors of the society have taken up, for some reason or another, the use of such plants. This trend may be destined to continue.
Invasive alien species are disrupting and changing the normal ecological functions of biomes, ecosystems, and the biosphere as a whole (CBD, 2009). They are a threat to biodiversity and can cause damage to, or even eradicate native species which natural cycles and other organisms depend on. While disrupting energy flow, food chains, and shaking the structure of ecosystems to the core, invasive species create not only ecological, but also a whole host of social, economical, and health issues that affect the livelihood of almost every organism on earth, including humans (CBD, 2009).
The International Union for Conservation of Nature (IUCN) considers the shrub one of the100 worst invasive species in the world. It is also a Weed of National Significance making it one of the 20 most problematic species in Australia. It is believed that the weed increases fire risk in the Queensland rainforest by changing where the fuel beds lay. Lantana camara, is known for being extremely invasive and detrimental to the biodiversity; it can be found in various tropical and sub-tropical environments on about 60 continents. The weeds alter soil quality, water availability and fire regimes which was studied in this paper. Two mechanism were studied, such as whether the fires were caused because the weeds are more flammable than native species, or did the change in forest structure from the weeds allow fire to spread. Leaf and twig dry matter was measured and burned in laboratory trials. L. camara was discovered to be less flammable than the native species in the area; meaning that the first mechanism hypothesis was not accurate. To test the second mechanism fuel bed depths, percentage cover by fuels, and amount of medium-size class fuels were measured. These were found to be higher in the parts of the tropical forests
The sunflower, original only to the Americas, has become one of the most important plants throughout the world due to its adaptability, diversity, and sustainability. It is a key component in cooking, human health, soil detoxification, and has been use in medicine, art and poetry.
