Certain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.
Zebra mussels are a big problem because they cost the economy lots of money, eat up almost all of the plankton, and they hurt aquatic life. My first reason we should rid of the zebra mussel is because they cost the economy lots of money. According to the article Zebra Mussels by MNDNR, “Zebra mussels can be a costly problem for cities and power plants when they clog water intakes.” They cost America 5 billion dollars a year just to replace things this small mussel has ruined. My second reason that we need to remove the zebra mussels
This industry not only provides the populous with inexpensive power but also creates a steady employment option. Besides an increase in the greenhouse gas, carbon dioxide, the mass accumulation of coal ash and its leaks and spills into local rivers negatively affect the environment (“Energy-Related”). According to Earthjustice, “North Carolina generates over 5.5 million tons of ash per year” ("Coal Ash Contaminates”). In Eden, N.C. in 2014, the largest coal ash spill occurred, releasing 39,000 tons into the Dan River, which supplies drinking water to surrounding communities, a habitat for aquatic organisms, and recreational activities (Gallucci). Coal ash, also known as coal combustion residuals or CCRs, contains hazardous byproducts from power production, including arsenic, lead, mercury, and chromium, that can poison drinking water sources for humans and devastate wildlife habitats (“Coal Ash Basics”).
However, some countries are able to control their population growth, such as London, Greece, Japan, Singapore and Israel. Many problems are caused when you live in an overpopulated city or nation to its residents, such as environmental and social problems. Daily, 25,000 people die due to hunger and 18,000 of them are under the age of 5, because their country can’t provide them with enough food to feed the entire nation. One billion people lack access to water throughout the world, because of water shortages. Another issue with water is citizens are trashing their oceans damaging the water we drink and the fish we breed.
A pressing social problem prevalent in the world today is the destruction of marine habitats which leads to the loss of food for humans. I am going to discuss the many causes of the deterioration of the marine habitats such as development, chemical run off into water supplies, bottom trawling and dams. “Habitat loss in these areas have far-reaching impacts on the entire ocean 's biodiversity” says National Geographic (2014). Our population is growing at an exponential rate; according to National Geographic (2018) they predicted that by 2050 (which is only 32 years away) that the population will grow by 2 billion more people. This means our planet will need to sustain 9 billion people.
Almost all the human’s daily activities negatively impact the whole globe, and as the population increases, so does the damage (Duncan). The first cause of overpopulation is the decline in the world's populations death rates. The death rates are only 55.3 million per year; while the birth rates are 131.4 million per year. One could see that the number of deaths is almost half the number of births. However, if we had balanced birth and death rates together; they would cancel out each other.
(How Does Water Pollution Affect Humans?) And India has the world's highest number of people without access to clean water, imposing a major financial burden for some of the country's poorest people. (World Water Day 2016) The effects of water pollution are Harm to the blood, damage to the brain, long-term buildup, and insidious uptake. (Sanburn, Josh, Sean Gregory, and Alexandra Sifferlin) Some 3.6 million people - including 1.5 million children - are estimated to die each year from those water-related diseases, including diarrhoea, typhoid, cholera and dysentery. Due to water pollution.
1. Introduction Water is crucial to our survival! Water is one of the scarcest commodities in the world at the moment; some argue that it is scarcer than oil. Wars have been fought over oil; therefore a war over water is a very big possibility in the years to come on this planet. With the current growth of the world’s population and the increase in demand for water in the agricultural industry, the issue of water scarcity is very likely to get worse and worse (Gupta, 2016).
Pollution is a big problem around the world that affects at least a thousand of animals,marine life and also causes global warming.Pollution can cause death or serious problems and diseases.A article Bios Urn states that “8.9 million people are killed a year from pollution”.It also says that 200 million people suffer from pollution.This shows why pollution is a really big problem. In this essay we are going to see how pollution affects the environment and the ecosystem.In addition to how pollution affects animals,plants, and marine life.Finally,how pollution affects human health. To begin with, pollution affects the environment and the ecosystem.Pollution has a big impact on the environment and the ecosystem because it
Almost 18,000 of them are children under 5 years old. Food production and distribution could catch up if our population stopped growing and dropped to a sustainable level. Water Shortages: About one billion people lack access to sufficient water for consumption, agriculture and sanitation. Aquifers are being depleted faster than they can be replenished. Melting glaciers threaten the water supply for billions.
