One of the biggest problems surrounding the protection of California’s plants and crops, is the threat of pests and invasive species. Pests are a constant danger as they can ruin plants by infecting them, or destroying them by eating away at the inside. There is also the danger of invasive species. The National

There are many invasive species in Florida, which affect the environment in many ways. First, one way is that the animal cannot thrive in its new environment, the reasons being; not enough food or the wrong climate. Another example would be, that the animal might thrive successfully and reproduce. This is detrimental to the environment because the animal or plant can wreak havoc and become an invasive species. Species can become invasive due to the lack of predators in its environment.

The Maryland ecosystem is being ravaged by several invasive species. These species are introduced into the ecosystem in several ways, with several discoveries of invasive species every year. Whether it be Wavyleaf basketgrass or Purple loosestrife, these plants are capable of outcompeting with native plants and causing devastation to the native ecosystem. These invasive species are damaging to the environment and we should work as a community to halt the spread and limit its impact on the ecosystem of Maryland.

What makes something invasive? Is it when the object takes over? When it reproduces to a great extent? When it takes over all of your space? These are all aspects of an "invasive" thing. Invaders cause other tiny problems along the path of their destruction that can be difficult to control. In Mark Sanchez's, "The Invaders," and Aaron Hartman's, "Kudzu: From Pretty Vine to Invasive Pest", two plants, the milfoil and kudzu, are taking over. These invasive weeds have more than just being invasive in common with each other, they also share a hand full of dissimilarities. These plants have gobs of similarities and differences between each other.

Another invasive species are the Nutria. The Nutria comes from South America. It is not exactly clear

Invasive species come in many forms; they can be plants, animals, insects, fish, fungus, organisms, and bacteria. Invasive plants are those which cause environmental, economic and human harm and originate from another area or region. They are a complex and difficult problem to tackle. There are more than 4,000 plants species found in Florida, of those 1300 or more are non-native or invasive. Many invasive species are taking over Florida’s waterways disrupting their natural ecosystem by outgrowing and replacing Florida’s native plants. Relieving the damage they cause is not easy, but scientists and members of the communities being affected are finding that it is achievable, as long as everyone works as a team to address the issue.

What is an invasive species? An invasive species is a species not native to an area, in this case not native to the Great Lakes area. A non-native species is a species that originally was not in a certain location but was brought there and causes a lot of damage. An invasive species also is a great danger to the environment and can cause damage to humans, plants, and animals. In Illinois and the Great Lakes area there are more than 180 invasive and non-native species. That means a lot of damage is made into our environment. One particular invasive species is Agrilus planipennis, more commonly known as emerald ash borer.

Invasive species are animals, plants, or fungi that are non-native to the place they are currently in. Some non-native species are not invasive, but if the organisms cause harm to the native species, then they become invasive. Some invasive species on the Pacific Northwest are nutria, bullfrogs, and yellow star thistle. These plants and animals ruin the ground, eat whatever they can fit in their mouth, and can cause diseases. These invasive species don’t help the environment or the organisms living in the Pacific Northwest.

The plants have been thriving through California, which then would lead to the plants going through parts of the Mojave Desert since it is located in California. The plants that are un-harmful are the ones that are native. The non native plant species are one of the leading causes of the many wildfires in the area. The ones to look out for are the Russian thistle, cheat grass, saharan mustard, giant reed, and the tamarisk (“Invasive Species”). Along with the non native plant species growing rapidly and out of control, there are also two latter weeds that have been growing along river channels through the Mojave Desert. Once a desert is damaged, it can take years to regrow the plants let alone centuries to return to the desert and be look somewhat back to a normal state of being (¨Air Quality Management¨). The non native plant species are fueling the desert wildfires. When native plants die off or get picked by another predator, the non native plants grow in place of the native ones (“Threats to Mojave”). The reason plants are causing the uproar is they have really fine native woods which tend to burn easily and the plants are so close together the next one just catches fire. Before different species came to the desert, the wildfires were not as much a problem as they are now. The Russian thistle, also known as tumbleweed, reproduces from seeds that fall off of the bush in the wind. The

Biodiversity boots ecosystem productivity where every little species plays an important role in maintaining a healthy community. Maintaining a viable habitat requires lots of efforts, determination and frequency. Invasive plants are a major threat to our natural environment. These invasions change the natural diversity and balance of ecological communities. They threaten the survival of many plants and animals. They are excellent at surviving and reproducing which out-compete the native plants. Understanding these huge consequences let us understand why volunteer activities like this are so helpful and needed. They play a huge part in contributing to our environment in many positive ways. Removing these invasive plants are helping a lot in restoring the habitat and giving native plants greater chance for survival. As time went by, these efforts will slowly help cleaning our atmosphere, providing our environment with fresh air and improve health effects in human (Sagoff,

An invasive species is a non-native species whose introduction causes or is likely to cause economic harm, environmental harm, or harm to human health. The term "invasive" is used for the most harmful aggressive plants & animal. These species grow and reproduce rapidly, causing major harm to the biomes in which they are introduced too. If most invasive species are left uncontrolled in certain situations they can destroy the ecosystem they’re in leaving it useless for native species. The longer we ignore the dilemma the harder, more expensive the battle for the biomes will become. Most invasive species can terrorize your ability to enjoy hunting, fishing, boating or other outdoor recreational activities. “The United States suffers from $1.1-120 billion per year in economic losses due to exotic, invasive species.” (Invasive)

Georgia has been invaded by numerous species that are known as harmful exotic plants and animals. It is so costly to attempt to control invasive species and the damages they inflict cost the United States annually an estimated $137 billion (Georigia Invasive Species Task Force, 2005). For example, in South Georgia there is an estimate of 7 million acres of Kudzu vine that originated in Japan and China. The damage that arises with the Kudzu vine is that it grows up to one foot per day and overgrows and shades out trees, covers houses, barns and road signs (Georigia Invasive Species Task Force, 2005). In order to make this a top priority some things congress needs to change is the revision of current United States policy on importation of live plants and animals and when considering, reviewing, or approving trade agreements they address specific invasive species. In addition, the implementation of prescribed burnings in areas with invasive species will help eliminate and control the spreading of such invasive species.

Influence on ecosystems range from human causes like the bulldozing of a forest to natural causes like a fire or a flood.  In recent times, the introduction and spread of invasive species has transformed native communities rapidly and, in some cases, created irreversible damages.  In the Earth’s history, changes have often occurred in the ecosystems.  For example, glaciers and the retreat of glaciers cause wide-spread changes.  However, although change is a constant in ecosystems, animals and habitats often cannot adapt to the rapid alterations of non-natural stresses.  Harm to the environment from the introduction of invasive species occurs through changes in the habitat and declines in the native species.  Invasive species

Invasive species are organisms that are not native to an ecosystem and cause harm to it. These organisms are capable of bringing about a great deal of damage to the ecosystems they are foreign to. This can range from disrupting the growth of the environment it has taken over to completely decimating other species. The introduction of invasive species to new environments often involves humans. The way that invasive species are introduced to a new environment varies greatly. Invasive species may be introduced by something as simple as humans accidentally tracking species into a new environment from the bottom of their shoes, or something bigger like destroying an ecosystem to clear the land, forcing the species that lived there to flee to a new ecosystem that can be disrupted by the presence of a new species.

Alcestis is a myth that is "the most touching of all the Greek dramas to a modern audience" (Lind 213). It is a tragicomedy by the playwright Euripides and it centers on the king and queen of Thessalia. Admetus, the king, has been fated to die yet, due to his alliance with Apollo, is given the chance to find a replacement. His wife, Alcestis, volunteers for the position claiming that she cannot imagine life without her husband. After Alcestis submits her life, Admetus discovers the pain of loss and even determines that Alcestis is the lucky one in dying.
