Overpopulation is a current environmental issue “where an organism's numbers exceed the carrying capacity of its habitat. In common parlance, the term usually refers to the relationship between the human population and its environment, the Earth.” IT is causing deforestation and starvations but we have to grow. Our population growth rate is increasing at a steady rate. We cant really lower the growth rate but we can build more cities where many people can live. 26.
From the time period of 1870 to 1900 the growth of big businesses in the United States had a major impact on the economy, politics, and the response of Americans of Americans to these changes. These businesses grew significantly in number, size, and influence and had an ever-lasting effect on Americans and their surrounding community. Industry and its new technologies have had an amazing impact on reducing the costs of the goods necessary to life, such as food prices, fuel and lighting prices, and the cost of living (Document A). The standard of living of most Americans should have increased, as more wages would be left over to spend on luxuries. Aware of the extra-money available to working families, the different pieces of a Big Business have acted in such a way to suck that extra-money from the poor families.
A straight line is produced from the data when plotted on a graph. This can be described by the mathematical equation y=2x. Y represents the population size, x represents time 2 in the number of individuals added during each time interval from the equation y=mx+b, data for any linear population growth can be described. Y represents the population size, x represents time, m represents the number of individuals added during each time interval and b represents the initial population.\ The number of individuals joined to the population increases at each time interval when a population exhibits exponential growth. 1,2,4,6,8,16,32,64,128.... is a pattern that a data set for a population that is growing exponentially.
As centuries came and went health problems increased. The Earth’s natural resources were diminishing. Some believed the causes were natural; however, studies concluded that the steady increase in population is a co-conspirator. In the 1960s when noticeable natural disasters were occurring, the environmental movement became forefront. The oil spills in California and Massachusetts raised serious issues warranting an environmental conference to prompt international awareness of environmental concerns.
The Positive Effects of Westward Expansion There were many changes in the United States during Westward Expansion. Though many changes were negative, the positive things outweighed the bad things. Without Westward Expansion the US would never be the strong, independent nation it is now and we gained almost one third of the land that we own now. Also, another positive effect on the United States was the California Gold Rush, which brought diversity to our country and created jobs. After all of the bad things that our country went through, we came out as a stronger nation.
Not only will the massive amounts oil produced from this area have an effect, it is estimated to create anywhere from 250,000-735,000 jobs. Just for a reference as to how much this will boost the economy, since 1977 the North Slope oil development has pumped 500 billion dollars back into the economy. This is now slowly running out of resources considering it reached its peak production in 1980; however to continue boosting the economy more exploration needs to be done. (source 2) Action needs to be taken immediately because from the date of approval to exploration it takes anywhere from 7-12 years until the first barrel of oil is recovered. (Source 1/3) The 16 billion barrels of oil that lie untapped there would be more than enough to replace the oil Americans would purchase from Iraq for over 58 years.
The industrial revolution has helped the nation and economy grown so much over the time but we know, nothing is perfect. With large factories come environmental hazards and with large buildings come migration issues for all animals. Over the years, we have learned that maybe we took too much too fast. The importance of the industrial revolution is endless. But looking back on it today, the world seems to be at a much quicker less wasteful speed.
Why? She explains: “Man has been the dominant sex since, well, the dawn of mankind. But for the first time in human history, that is changing—and with shocking speed. Cultural and economic changes always reinforce each other. And the global economy is evolving in a way that is eroding the historical preference for male children, worldwide.” Rosin’s article is well documented and forceful in argument.
He discusses that although the population is growing, our planet may not have all the resources it needs to accommodate the growing population. Kunzig states that with the increasing population will the planet have the resources it needs to support our growing population? It is discussed that the death to birth rate is completely unbalanced with 5 births to 2 deaths every second, which is causing our population to grow drastically. It is also discussed how the life span has also gone up around the world and by the year 2045 there will be 9 billion people living on this planet. Both are very big issues to worry
2. “Explain the main point concerning exponential growth and whether it is good or bad. Compare exponential growth to a logistic growth curve and explain how these might apply to human population growth. What promotes exponential growth? What constrains population growth?” Good or Bad- Exponential growth “means that the annual growth rate is a constant percentage of the
