Humans Hinder Animal Movement

The article I've chosen, "Humans Get in the Way of Mammal Movement" highlights the consequences related to human invasion of territories mostly occupied by animals. The text begins by noting how over fifty different land-based animal species suffer as a result of the modification humans have made to certain landscapes. The study conducted by the University of Maryland took into consideration a vast majority of species, across the entire globe. Ultimately the goal was to detect whether or not human interference with animal species effected the daily life of the animals. To add, the researches took into account the average travel distance an animal normally travels before the survey and compared that to the amount after the survey. The researchers also had to compare walking patterns of each animal into zones, some that were highly dense to less dense. In essence, this would allow them to determine the whether or not human interference hindered their ability to travel a sufficient distance per day. After analysis, the researchers were able to conclude that animal species barely walked less in the course of an hour, but over the san of 10 days, the amount of their distance was down 50%. Infrastructure was the leading cause of animal limitation to walk more seeing as it blocked their ability to continue walking in that direction for food, water, shelter, etc. This also shows how animals limit themselves to stay outside of territories dominated by humans. Finally, animals bring nutrients from area to area around the world, which is why it is essential they move and cover the ground that they are meant to cover.
In my opinion, the article demonstrates how human life has disrupted and obstructed with daily animal life. Animals on average are covering much less distance. Solutions the author raised would be to -after examining travel patterns- set up corridors that animals seem to go towards, thus allowing the animals to travel their average daily distance while not developing infrastructure near their territory. However, this is easier said than done in the sense that often individuals who own land will want to capitalize off of potential profits of the land which could mean selling that land to developers who disregard any environmental impact associated with the deforestation of wild life area. Thus, Government action is needed to sign a policy that takes into account where species live and their daily routine to deem certain land as non-developable. That being said this would take yearly subsidies to the land owner to ensure his investment is also profitable.
