Environmental health Unit 38 P1 Explain how human activity can damages the environment For years now we have been warned about human activity destroying our planet and environment. Some of the things that humans are affecting are Climate Change, Depletion of Ozone Layer, Pollution, Deforestation and Extinction of Species. Overcrowding, urbanisation and population growth Overcrowding can affect our planet more than some people think, Overcrowding means more people this means we use more natural resources this means the earth in the end isn’t going to have enough resources to support the growing population. Remember every person on the planet takes up space which could be used for farmland, and forests. People excrete wastes and litter that flow into water systems, and animal habitats, this is slowly polluting water and killing wildlife.
We Should Be Concerned About the Speed of Population Growth in South and East Asia In a region that’s population is growing in between 1 and 2 percents annually, and is already struggling greatly to take care of the people that they have, something needs to be done before it gets any more out of hand. As it stands now the population density of East Asia is around 131 people per Km, and South Asia’s isn’t much less. There isn’t enough food to support the current population, nor is the health care system in place able to take care of the number of people now. Crime rates tend to increase as a country or region's population increases. Something needs to be done to either control the population growth in these regions or find a way to make it possible for such a large number of people to live in that region.
More animal species are becoming endangered or extinct as a result of global warming.” “The carbon emissions, pollution and human health problems that have resulted directly from the Industrial Revolution’s accomplishments have only been disastrous for the world environment. For example the increase of the production in the textile industry, iron and steel and the steam power. As a result, many people died cause of too much smoke spread in the air. Another example according to the reading, air and water pollution came from coal burning, as well as most stages in the production of metals and basic chemicals. Moreover, “The advent of the steam locomotive and railroad also saw the start of major pollution caused by big business, which is all too often seen today.
It also affected the economy as payrolls, pay rates, salaries, or wages decreased as the population increases due to rapid urbanization. The rapid urbanization and soaring population also resulted in rapid spread of diseases due to the condition and situation of the new industrial city. 2.) How did the factory system change the way people worked? Prior to the Industrial Revolution, most of the people migrated from farms to cities, also known as urbanization.
One major threat is that coral reefs are under huge stress due to the impact that human activities are having and in fact already 1/5 of the world’s coral reefs are so damaged that they are beyond repair. The increase of average global temperatures is leading to an increased rate of ice cap melting. This is due to global warming, making a global threat to all ecosystems including the coral reef. The reason for this is that the melting of the ice caps releases more fresh water into the oceans, reducing salinity making sea level rise. Due to sea level rising coral reefs are getting destroyed, as they cannot survive in water above 25m.
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.
The economic growth has put too much stress on the nature. There are many types of environmental damage, and Mckibben examines climate change in the chapter. He points out that climate change is not some future specter and it’s already emerging as the biggest problem the world faces. He also insists that the richer people get, the dirtier the air is, and this is indeed one of the environmental destruction that he described in the chapter. Another destruction that he talks about is the global warming.
As a result of this, plants and animals are forced to adapt to significant changes that threaten their way of life. As explained by Suzuki in the article, every year at least twenty thousand species disappear forever and the rate of extinction is speeding up largely due to human activity. Many living things are now paying the price for all the man made pollution that has been created as a result of global warming. Furthermore we as a community do nothing to stop global warming and feel no sense of responsibility or duty to care for the overall well being of our world. Big businesses are releasing harmful chemicals into the atmosphere and oceans.
Regardless, there continues to be many socio-economic problems associated with it. With the attraction of new businesses, wealthy professionals, and tourism, there is a trend for property value and rent prices to rise, causing less wealthy residents to move out. The issue of gentrification is one of great controversy and has many interpretations. If one is defining gentrification as simply urban revitalization, it is hard to understand why people are offended by the idea. The more broadly understood definition, found in the Merriam-Webster dictionary, among others, is “the process of renewal and rebuilding accompanying the influx of middle-class or affluent people into deteriorating areas that often displaces earlier usually poorer residents” (Webster).
Human activity is the main cause of environmental destruction. For example, overpopulation not only results in serious pollution, but also damage to the natural resources. It is inevitable that when the global population grows, the demands on natural resources will rise. Similarly, as the consumption of natural resources exceeds the rate of natural regeneration, so the natural resources will be depleted (Magdoff 2013; Mclamb 2011; Hinrichsen and Robey 2000). As a result, the standard of living
