Over the years, the native plants in the environment have been overpowered by the foreign invasive species such as French broom, Scotch broom, and Reed canary grass. Due to this predicament, the native species populations have been decreasing and causing the biodiversity, or the diversity in an environment indicated by the numbers of different species of plants and animals, to decline as well. For example, in Monterey Bay, hundreds of native organisms are dying due to an invasive species known as French broom. Many native birds and animals refuse to eat this plant because it is not native; therefore, they starve to death because all of their other food sources have been depleted (Nichols). As shown in figure 1 (left), Canada is one of the countries …show more content…
The IASPP shows the initiative Canada has taken to get rid of Scotch broom and reed canary grass, as listed on the website. Within Canada, the bar graph shows the number of projects funded by IASPP and in which territories or provinces it is located. As shown above, the most amount of projects funded by IASPP is 33 in British Columbia, however, it isn’t that much. Furthermore, according to the Convention on Biological Diversity, “Globalization has resulted in greater trade, transport, travel, and tourism, all of which can facilitate the introduction and spread of species that are not native to an area. If a new habitat is similar enough to a species’ native habitat, it may survive and reproduce” (CBD). Most of the causes for the spread of foreign species of plants are because of
Canada is a very large country, with areas of land in various climate regions, and land regions, thus having many ecozones that differentiate from another. The most populated ecozone in Canada is the Mixedwood Plains; the ecozone we are located in, named after the mixedwood forests that are native to the area. The Mixedwood Plains is one of the smallest of the Canadian ecozones, spanning only 175 963 kilometres squared. The Mixedwood Plains is bordered by three of the great lakes on the southern side of the ecozone, and comes up along the St Lawrence river to southern Quebec, and fills the tip of Ontario. It has rolling plains and small rock formations and escarpments. The Mixedwood Plains contains over half of the Canadian population as it contains some of Canada’s largest cities, including Toronto, Ottawa, Montreal, and Windsor. The Mixedwood Plains has a relatively temperate climate with summers ranging an average temperature of 18o c – 22oc and winters ranging from -3oc - -110c.[2] Native mammals to the ecozone are black, brown and grizzly bears, grey wolves, coyotes and foxes, raccoons, squirrels, and other small mammals. Avian species include brown sparrow, hawks, crows, cardinals and bluejays. Fish are bass, trout, carp and pike. The Mixedwood Plains is made up of about 40% water, and contains over 20% of the worlds freshwater. One of the major problems in the world today is freshwater shortage. Because we have ample supply, we don’t notice, but much of the world is short on water. There are more water resources, but one of the largest is being quickly polluted and populated by invasive species .
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.
Another key resource in the attraction to Canada was the fur that was available. In the 17th and 18th century, fur was in high demand in Europe. Fur pelts were seen as fashionable, and of high value at the time. Beavers were a main provider of fur pelts, and were decreasing in amount within Europe, due to the high demand and mass production of these fur pelts in Europe. This relates to why the Europeans were very motivated to trade with Canadians, as these fur pelts would have been of high value and demand in Europe, creating a boost in the economy and profit for the merchants. In Europe around 1600, North American fur was also seen as of higher quality than European fur, thus concluding that in many ways North American fur was of a greater value and ‘superior’ to fur originating in Europe. These were main reasons that
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.
Any person, place or event that has held the honour of being commemorated in Canada has been recognized of an extreme importance to the country. It is impossible to research commemoration in Canada without reading about world war one and two; The great wars are arguably the most commemorated events in History let alone Canada. Understanding this they are not the only events that receive attention from Canada, the government recognizes many other occurrences as, well, anything from Sir John A. Macdonald day on the 11th of January to the anniversary of the statute of Westminster on the 11th of December. I do not believe that any one event can be placed above or below another, and that they all hold a value in whatever way that may be. This Essay
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).
There are more than 1000 people trying to immigrate to Canada. What if Canada contributed more to help the newcomers to Canada? Most of these newcomers are Muslim, and they are mostly coming from Syria, Iraq, and other countries that are at war. They are forced to leave their homes and can barely survive. These people are very vulnerable to almost anything. If Canada inherits these newcomers, it will gain a greater security and become more diverse. This will also become an advantage in the future. The government should help newcomers to Canada because they are vulnerable. It also gives Canada a chance to improve its diversity and safety, and it will benefit Canada in the later years.

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.
A different scenario takes place when an alien species is transported to a new area. Although direct competition with similar species is still a problem, the new kid in the block may have no natural pests and diseases. Thus, large stands of monocultures can occur. It is generally accepted that one plant species will support 10 species of animals. If one species takes over 99% of a given habitat dozens if not hundreds of species are lost from that area and some populations are stressed enough that extinction is possible.
The Canadian government’s move toward globalization is creating a level playing field for the Canadian economy and the culture by closing the gap of trade barriers and opening up the market, thereby making Canada a more industrialized and multicultural society. Globalization, the term is defined as the interactions among people of different nations through international trade and communication integration. This approach is unlocking the nationalistic perspectives to broader outlook, thus encouraging multiculturalism as well as linking ties among the nations.
Invasive species only started to show up in the United States when the Europeans started to arrive. Beforehand, very limited contact was made in this particular region of the world, so very few invasive species came into North America. When the Europeans arrived in 1492, after Columbus discovered North America, they brought their own culture and essential food and animals with them. At first, it was just the basics of maize, wheat, pumpkins, and squash, but later on it also included cows, chickens, and horses . As more Europeans flocked into the country, non-native species began to appear in the area. Often, as non-native species appeared it led to unintended consequences of destroying gra...
Modern-day genetic technology has granted mankind with the opportunity to bring back extinct species from the dead. If humans have come to possess the DNA from an extinct animal population, it is possible to create an identical clone of the animal in question, effectively “bringing it back from the dead”. Many ethical dilemmas surround the practice of de-extinction, and rightfully so. Recreating an extinct species could produce groundbreaking scientific breakthroughs, generating exciting opportunities for future genetics-based research. However, there could also be monumental consequences: the newly revived, once-extinct species might destroy the ecological equilibrium of modern Earth
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).
One of the big causes of extinction or the endangerment of species is foreign species entering a habitat. This species that are not native to the land can disrupt the food web in that community. These species take control of the food web and endanger some of the other species. The native species become endangered and over the course of many years they either adapt to their new way or life, the foreign predator leaves or is killed off due to the different environment, or the species is killed off and becomes extinct. Organizations like the “World Wild Li...
