Do you feel we are nearing the Earth's carrying capacity for our species? Discuss any impacts the exponential growth of our species could have on other species and their habitat. Finally, explain what you could do to reverse the trend of competitive exclusion by humans so that we do not exhaust the limited resources of the Earth?

“In a mere half-century, the number of people on the planet has soared from 3 billion to 7 billion, placing us squarely in the midst of the most rapid expansion of world population in our 50,000-year history — and placing ever-growing pressure on the Earth and its resources” (Haub, 2011).Humans are very unique among animals on the planet. Furthermore humans have the upper hand over any other species on earth simply because we have the ability to effectively communication, opposable thumbs, and other traits. However we survive and reproduce in wide variety of environments through cultural adaptations; animals have similar traits as humans, making them truly unique among their own. But likewise species cannot compare to human’s ability to run long distances since our two legs allow us to run exceeding distances before excreting large amounts of energy. “Humans are truly amazing unique animals and our abilities to continue expand our span of thought show that we are capable of many more great things” (Jasmin, 2012, para. 3). In contrast, other species are able to stay alive, provide their families with food to survive and reproduce due to biological adaptations that result from eons of natural selection and biological evolution.  “Humans, like all organisms, can only sustain themselves and their populations by having access to the products and services of their environment, including those of other species and ecosystems. However, humans are clever at developing and using technologies; as a result they have an unparalleled ability to manipulate the carrying capacity of the environment in support of their own activities” (Freedman, 2013).

In our current lab, “Population Biology,” we are learning the principle of competitive exclusion: that no two species can occupy the same niche. Now, let’s take this concept and expand it to the scale of the entire Earth. The human population recently reached 7 billion people. Do you feel we are nearing the Earth's carrying capacity for our species? Discuss any impacts the exponential growth of our species could have on other species and their habitat. Finally, explain what you could do to reverse the trend of competitive exclusion by humans so that we do not exhaust the limited resources of the Earth?

I do not feel that we are nearing the Earth’s carry capacity for our species because so many  humans die off every year and new technological advancement. I think also in this new generation women are waiting late to have children and that mean less humans on the earth. Too many species on the earth can damage the habitat. A sustainable habitat is one which supply of and demand for resources has to be balance. I think it is important that we do not deplete our resources this could lead to some problems such as: disease, poverty and death. In order for impoverished people to survive they could be forced to destroy the environment (Lin, 2008).

I think we could reverse the trend of competitive exclusion by humans so we do not exhaust is by conserving. For the population to have sustainability they must practice conservation this will allow humans to have enough resources for future generation and have the capacity to carry species on the earth. Conserving the energy, resources and materials on earth it can be done by using new technologies and low birth rate. Technology points to the technological innovation as the answer with hybrid cars, green design to reduce ecological impacts of consumption without compromising high standard of living. Virtual worlds present the intriguing prospect of substituting virtual consumption for real consumption by offering experiences, opportunities and pleasures that satisfy many of the motivations that underlie modern consumption. New technologies and virtual worlds offer the promise of increased efficiencies to save our earth (Lin, 2008).
