After the invention of the steam engine and steam pump it was much easier to provide energy, since steam power was reusable and more efficient. This extraordinary invention of the steam engine allowed new jobs to form and helped the Industrial Revolution develop. Britain had a huge supply of coal which allowed them to create steam powered factories for objects that were usually handmade. Steam power also allowed ships and trains to go back and forth between places faster and therefore developed trading and transportation. The steam engine may have created new jobs, but it increased child labour.
Freshwater ecosystems have lost a greater proportion of their species and habitat than ecosystems on land or in the oceans; in addition, they are probably in greater danger of further losses from dams, pollution, overfishing, and other threats. In extent, freshwater ecosystems are quite limited, covering only about 1 percent of the Earth’s surface. Yet, they are highly diverse and contain a disproportionately large number of the world’s species." Freshwater life zones that provide important natural resources and natural services to human is being damaged and degraded by humans. • Increased habitat loss.
Whereas that energy costs almost ⅓ or ½ of the total cost of producing freshwater. Therefore not all countries in this world will be able to afford or product desalination plants. Another disadvantage are the environmental impacts the desalination plants make. Removing the salt removed from the water is a big issue. The discharge which is also known as brine, lowers the amount of oxygen in the water at the disposal site, which leads to the killing of animals that are not used to the higher levels of salt.
Nuclear energy does not result in the emission of any of greenhouses gases and other poisonous gases for instance, nitrogen oxides and sulfur dioxide. Nuclear power produces clean and compact energy with no carbon dioxide and using it is the best way to stop the global greenhouse emission causing global warming (Greenberg and Heather 820).
One example is eutrophication which causes a dense growth of plant life leading to the death of marine life from lack of oxygen. This is significant because it has serious, long-term effects. The most remarkable effect of eutrophication is blocking light from reaching the water. Smith and Schindler (2009) investigated that eutrophication prevents the aquatic plants from photosynthesizing and that would lead to reductions in fishes and in the food chain in general. In addition, when fishes die from lack of oxygen, they sink to the bottom, and the microbes that break down the organisms need oxygen to continue this process.
Unlike many other kinds of resources, its generation process uses directly natural water which does not run out quickly or raise in prices. Additionally, hydroenergy can be considered safe when being generated since it only involves water instead of other fuels. Comparing to nuclear power, hydropower does not require safety regulations or raise concerns among the public about its threats to the environment. What is more, hydroelectric power plants are claimed to require low operating cost as there are only a few parts in the process while the water can be
The household energy bills have increased by 4%. In USA, prices of electricity have risen. In the first half of 2014, the prices of electricity have risen by 3.2%. When the prices of the energy sources are too high, energy consumers would be unable to afford
The speed and nature of energy innovations in the following centuries led to dramatic transformations in human life and economy as well as major environmental impacts. In the 19th century, a number of agrarian economies dependent on wood and animal power became industrial economies driven by coal and the steam engine (O’Connor, 2012). Many economies underwent another transformation relying on a variety of fuels in internal combustion engines and electricity generators. As the demand for energy services has changed, so have the fuels and conversion technologies employed to meet those demands. As populations have risen and economic activity has expanded, energy consumption has increased, primarily through the use of fossil fuels (O’Connor, 2012).
Salinity dramatically impedes plant growth, leading to a decrease in crop yield and quality. This occurs due to two mechanisms: osmotic stress and ion toxicity. Osmotic stress occurs because saline soils have high osmotic potential, so plants which grow in saline soils have difficulty taking up water, resulting in low cell turgor and slow shoot growth. Ion toxicity occurs because saline water moves up the transpiration stream, causing Na+ and Cl- to accumulate
However, when traced, its causes are heavily influenced by man. In terms of the photosynthesis process of plants, climate change has numerous negative effects. It impedes the photosynthesis process in situations where an increase of temperature occurs. This leads to the production of less oxygen and food (glucose) which directly affects the food availability of humans. The decrease in the yield of crops has a huge and significant impact on countries, especially poorer nations.
The major sources of the excess nutrients comes from over fertilization of crops with animal manure seeping into waterways, and animals having direct access to waters where waste is carried into the watershed (Baker, 2015). Prior to industrialization, the forests used to serve as buffer zones from the farms to naturally sift out much of the excess nutrients. With the growth of population, farms, and factories, thousands of acres of forest has been leveled, eliminating the natural barrier. Along with the with forest loss, the use of pesticides and chemicals has degraded the water so much that the Bay is currently on the Environmental Protection Agency 's "dirty waters" index.
Overfishing is certainly an environmental issue because it affects the planets ecosystem due to human interference. One example of this is when a marine species is exploited, other species are also affected directly. According to the article, ‘Global Consequences of Overfishing’ states that, “...recent studies suggest that overfishing of large shark species has had a ripple effect in the shark 's food chain, increasing the number of species, such as rays, that are usual prey for large sharks, which result in declining stocks of smaller fish and shellfish favored by these species” It is also important to mention that overfishing often leads to the killing of other animals unintentionally. This is called bycatching. Some marine species that are affected by bycatching are juvenile fish, bottom feeding organisms, sharks, whales, sea turtles, and birds.
