The author from nature.com claims that “nations must
keep expanding conservational efforts to avoid a biodiversity conflict”. To stress the main claim of the article the
author includes statistics about the number of endangered species and the number
of species that go extinct every year.
The author also mentions contributing factors to the higher rate of
extinction like climate change and invasive species, all of which relate
directly to human activity.
Conservational efforts are mentioned in this article, but the author
claims they aren’t enough and if the rate of extinction continues at its
current rate then the earth could witness its sixth mass extinction within the
next couple of centuries. The author
also argues that the cost to protect these species and their environment is
nothing compared the economic benefits these species and environments could
contribute.

Scenarios for Mitigation and Recovery." PNAS. 8 May 2001. Web.

The authors claim that the “the current massive
degradation of habitat and extinction of species is taking place on a
catastrophically short timescale, and their effects will fundamentally reset
the future evolution of the planet's biota”.
To get this point across the authors reference past extinctions and the
timescale in which they happened and how long it took the earth to
recover. They also argue the importance
of recovery in human dominated ecosystems.
This article gives different scenarios that provide solutions to the
claim they are making. These authors
build upon the idea that something must be done to prevent to loss of
biodiversity and even provide examples on how this can be done.

The author claims that conserving biodiversity hotspots is
key to preventing habit loss and the extinction of species. Biodiversity hotspots ranks conservation
areas by their importance, basically stating that some areas are more important
to preserve than others (hotspot expansion strategy). This relates to previous claims because
argues a solution to increased rates of extinction and provides a conservation
effort. This article from Nature gives information about the
financial aspect of this claim by providing funding information.

of Earth's Ecosystems." Science. 25 July 1997. Web. 25 Sept.

The author claims that ecosystems are dominated by humans
and directly affected by human activities and processes. The article makes claims on how humans are negatively
impacting ecosystems by destroying them through habitat destruction (due to the
increasing population). This article
directly relates to the main topic of the increased rate of extinction because
it elaborates on the topic on how humans are influencing the rate of extinction
through processes that destroy natural areas.
The human population is growing, thus more land has to be devoted to sustain
the growing population through process like land transformation which cause biotic
changes and alterations to biogeochemical cycles.

The
author of the article Contemporary Mass Extinction
and the Human Population Imperative makes the claim “humans and their predecessors have accelerated the loss of Earth’s biodiversity into a sixth global mass extinction”. To support his claim the author organizes his article in to sections they focus on key topics. The article relates to the main claim from the article from Nature because it describes how humans specifically influenced the rate of extinction through their behaviors and growing population size. The author also believes that the human population should be at the forefront of conservational strategies. He believes that until the issue of over population by humans is addressed, even with the best conservational efforts, the rate of extinction will continue at its current pace.
