Purple Loosestrife is a highly invasive non-native plant that threatens significant portions of Canada and the United States marsh, swamp, and coastal habitats. It has many common names such as spiked loosestrife or purple lythrum and its scientific name is Lythrum salicaria.

It can grow 1 – 8 feet tall with a width range between 3-6 feet.…

Chris and Zach are economic majors which is another reason they wanted to visit because they…

According to Heather Scoville, in evolution expert, in her article, What is a Niche? “A niche is a word that is used in ecological biology to define an organism's role in an ecosystem.” This means the place an organism lives, the organism's "job" in that environment, what an organism eats, and how it interacts with other biological and non-living species. There must be a symbiotic relationship between all species. The three main niches an organism might contend with are commensalism, predation…

The fall of the ancient civilizations of Rome, Han China, and Gupta India shared common features. A failure of leadership brought down Rome and Han China a gradual internal disintegration, growing economic chaos, labor forces going wrong not being inadequate, epidemic disease, with a break-down of loyalty to the centerplace city or may we say the capital. These cities were so tightly drawn together that because of one came failing internally the other became to crumble also. The methods that…

present from the beginning of the story with the death of Alicia’s and Jordan’s marriage followed by the slow death Alicia suffered from the blood sucking parasite. Quiroga used the the death of Alicia to evoke a fear within us for when we go to sleep on our pillows, especially if it was a feathered pillow since it is known that these parasites can be found there. There exists the possibility that we can suffer this death without realizing it just like Alicia did. This short story makes a…

Food, probably one of the most important resources on this Earth, is becoming scarcer and scarcer by the moment. With the UN estimating an extra 2-3 billion mouths to feed by 2050 and crop production being undermined by 2 percent per decade, the prospects of preventing the crisis in time look bleak.” (TechCrunch.com). Mankind is slowly inching toward a dystopian future where food shortage will trigger riots and wars. At this moment, the world is facing one of the largest challenges yet. With…

In biology, this is known as mutualism. Man is no longer the parasite of nature as identified earlier. We should destroy the concept that man has benefitted from the Earth’s deterioration, because he too will suffer and pay for the consequences. The ideal metaphor here is that the earth is a living creature with…

The issues that animals are put through for entertainment, experimentation, food, clothing, and wildlife is horrifying. Animals are enslaved, beaten, electrocuted, strangled, burned, stabbed, and skinned alive to be used for human use and consumption. For the clothing industry, millions of animals are killed by being electrocuted, strangled, and skinned alive. This issue is very important because clothing should be made out of fabrics rather than animal fur. Millions of mice, rats, rabbits,…
