Impact of Population Growth to Environmental Science Essay
IMPACTS OF POPULATIONS GROWTH Introduction Undoubtedly, the population growth is one of the most influential social issues in the recent years.
As the earth’s population rises, the changes in different aspects, environmental, global economic and political, affect our individual life. Technology and advances in medicine have dramatically increased the average human’s life span. However, the important questions are that what impacts the growth of population has on you, how to get ready and adapt to these changes, and what can you realistically expect for the future.The U. S. Census Bureau has recently estimated that the earth’s population is more than 6 billion. The human population grow sharply since the end of the black plague in 1300s. Various censuses have projected that in the next 30 years the population will go up by more than 3 billion.
No matter it concluded the outcome of overpopulation is a disputed subject or note, but it is a fact that more cities will continue to grow, waste and pollution will be on the rise, and natural resources will continue to be depleted.Example of Effecting Factor Here is an example of the effecting factors. The fishing industry is a good example to illustrates the effects that bring by the population growth. For example, demand for fish such as tuna, salmon has grown sharply in the last 20 years. Technological advances have aided fishes easier to catch in the fishing industry. Although it is a kind of an inexpensive fish, the market value has gone up, and tuna is even auctioned off to the highest bidder in seafood auctions.
When a company buys this fish, it is then put into refrigerated containers and flown to different parts of the world. The repercussions put more strain on the tuna population as it becomes an even more desired delicacy. And it is predictable to see that the price of tuna will continue to rise. However, the difficulty of enforcing a global reduction of fishing tuna is that not all countries are willing or able to afford to limit this industry.
This example demonstrates the pitfalls that a population increase has on politics, natural resources and economic markets.Environmental Sustainability As cities grow larger in size, the natural land around them is being turned into homes and office buildings. More parks inside cities are needed to allow for the large amount of urbanization. These parks help to beautify the city while helping to preserve our environment. However, while we build these homes and cities we are also using more and more lumber and other natural resources. It is important to limit how much quarrying is allowed in one area and they need to be replanted instead of left bare.If you have ever seen the aftermath of a quarry you would understand how it is a scar to the earth.
Indeed, we, the world citizens’, individual responsibility can actually play a large role in ensuring that environmental problems limited. By using sustainable practices in your home, you can maintain your family leaves a smaller carbon footprint. The Global Market An basic understanding of the global economic market is needed to analyze how the population increase will affect the economy. Let’s see an example of the China.In the past decades, the China’s population has grown to more than 1 billion, and its increase results in a competitive manufacturing market.
Products made in China are spreading to more and more areas in the world. This has pushed China into the forefront of politics, which further affects the global economy by the money China lends to foreign governments. How this trickles down to the everyday person is the fact that our economy is tied to China’s and those of other countries. When economies fail in foreign countries it creates a domino effect.Our gas prices are determined by prices set by another country. Therefore, every time we use oil in our cars, we are affecting not only our market but others.
Political Factors The political scene is progressively changing for many countries. The Middle East is making strides toward democratic political systems due to the population growth. There is also a direct relation between a less-restrictive government and the ability of a country to compete in foreign markets. Policy changes in foreign countries obviously affect people’s jobs and lifestyles.
