Canada Thistle: Can Humans Harm The Environment?

An article states, “If they do manage to survive in the wild, domesticated animals take resources from native species,” (Pesky Pets, paragraph 4). This exemplifies the damage that invasive species cause to native plants and animals. An invasive plant could poison native animals, which would unbalance the ecosystem. Some may believe that if humans step in they will cause even more unbalance. However, this is not a credible statement because those people are not taking account of the amount of disturbance that will occur if we don’t do anything. The amount of damage will be miniscule to the amount of damage that would be upon the ecosystem if nothing is done. Therefore, humans must take action before any harm falls upon the native plants and

What are invasive species? An invasive species are organisms (plant, animal, fungus, or bacterium) that are not native to an area and has negative effects on economy, environment, or our health. Not all introduced species are invasive. Invasive plants and animals are a great threat to biological diversity and habitat loss. They can cause many health effects to people and animals and can also destroy personal property. Invasive species don’t always have to come from a different/foreign place. They can be considered invasive if they don’t belong together with other organisms.

A species that is introduced to an ecosystem by humans can harm ecosystems in many ways. Animals that are introduced into a new area, could hunt a main food source for some animals, causing that population to decrease. Plants could be poisonous, or need to feed off of other plants. Species introduced into an ecosystem by humans through off the natural balance of the wildlife.

An invasive species is a species that comes out of its natural environment, and enters another. These animals are usually very bad for the ecosystem and may cause an unbalance. These animals usually come in with many competitive advantages and can easily dominate any competition. This will give them the ability to eat as much as they would like without being threatened in any way. This could possibly diminish many populations and end an entire ecosystem.

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.

Invasive species are very common all over the world. Invasive species are an organism that lives in an ecosystem in which they don’t belong. Invasive species are not only dangerous to people, but also the ecosystem and must be removed.

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 don’t just cause monetary damage, they can completely disrupt and destroy ecosystems. Invasive predators like the brown tree snake can hunt native species to extinction because these species have not evolved defences against them. Even herbivores can cause indirect damage by feeding on the same plants as native herbivores therefore taking away their food sources. Plants can cause damage as well. Through various strategies they can take over the land where native plants would normally grow diminishing native plant populations. No matter what kind of creature an invasive species is it can still cause damage.

Significance: The question of whether or not invasive species impact the environment is an important one. The answer affects everyone. In today’s world, we take the outdoors for granted. People don’t realize how much it does for us. It provides economical resources, areas to relax, and oxygen for us to breathe. Without these simple things our lives would change drastically. Life as we

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.

Invasive species are plants or animals that spread to a non-native ecosystem and cause harm to that area. Common characteristics of invasive species include their ability to permit a variety of conditions, produce lots of seeds or eggs, separate easily, has long growing period or quick reproduction time, and their new environment has comparable conditions to the original habitat. Invasive species most often have negative impacts when they are transported to another environment. A recent study done by the Center for Aquatic Conservation describes the effect some invasive species have. In various states of the U.S, it has been found that invasive species are costing more than “$200 million a year in losses to commercial

From the smallest fly to the blue whale, from a blade of grass to a towering redwood, everything exploits the natural resources that Earth and its other inhabitants provide. In order to ensure its survival, an organism must assimilate itself into the food web or risk extinction at the hand of natural selection. Sometimes, a species is accidentally or purposefully introduced into a new area. These newcomers, commonly known as invasive species have no choice but to make themselves a part of the food web or die out. Unfortunately, that usually leads to fierce competition for resources between a local species and the invasive one, in which only the victor is allowed to survive. In a relatively short amount of time, the sudden pressure on resources can completely upset and destroy an ecosystem, taking the invasive species with it. With the invasive species destroyed, the ecosystem can slowly rebuild back to the way it was before. According to National Geographic, an invasive species is a “type of plant or animal that is not indigenous to a particular area and causes economic or environmental harm.” (National Geographic).[6] Based on that definition, humans sound suspiciously like an invasive species, except on a global scale. If humanity does not decide to become more sustainable soon, we will suffer the same fate as other invasive species: extinction. Luckily, the pressures of human exploitation of the environment for resources can be mostly eliminated through the use of

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

The biodiversity effects of non-native invasive species have been described as “immense, insidious and usually irreversible” (Veitch and Clout, 2002). There is significant evidence proving that invasive species can cause severe economic, environmental and ecological damage (Mack et al., 2000). A lot of time and research has been devoted to dividing the world into regions with distinctive habitats and species. Numerous pathways, mostly anthropogenic, are breaking down these realms and facilitating the ecological and biological invasion of non-native 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.
