Environment: Pollution and Human Activity

Nowadays the Earth faces a number of serious problems, such as the surroundings pollution, the increasing population, the fatal effects of nuclear weapons, etc. The problems arising from not just development in terms of science and technology that as well the increase in human demands based on population and economy.According to Professor David Karoly from the Department of Earth Sciences at the University of Melbourne, it is time to take urgent action to irksome global warming by human activities, because the impacts of human-caused climate change in many an(prenominal) natural systems oftentimes earlier than previous studies had projected which are being seen (Proof humans soak up damaged mankind, 2008). There is unconvertible fact that in history of humanity, human causes detrimental effects on earth. Indeed, human activity affects nature and human environment. For centuries, many activities of human hand destroyed ecosystem of the Earth.Deforestation and over-hunting is one of the main causes of this serious situation. The world is re eithery big, but natural resources are not endless. In fact, Dave Gilbert (2012) announced that nearly a fifth part of the Brazilian forest has been lost since 1970. That means all of the trees, plants, insects, animals and people who live there either killed or forced to find a new home. The world population is growing rapidly, so people pauperization food and shelter. Many food and housing means that they need more(prenominal) than land from nature. Therefore, they cut vanquish trees to build houses, deforest to plant vegetables and raise cattle.They destroy natural areas in order to expand cities and towns, and they overutilisation natural resources. Now people lone(prenominal) ass see some animals in the zoo because they have disappeared in nature. In addition, intensive and indiscriminate fishing in fresh urine systems, such as Lake capital of Seychelles in East Africa have catastrophic effects may pro ve to biodiversity (Elsa & Michael, 2011). Poaching is not only a serious problem but withal massive over-fishing. Many nations have banned nonlegal activities, but enforcement is very difficult. Industrial pollution and daily waste is also a major operator affecting the environment.Admittedly, people are producing more and more rubbish, because they prefer to eat the ready-made food. This has given hold up to the rubbish production. These garbage produce in many ways and unfortunately, have bad effect on ecosystem. Susan Patterson (2014) showed that farmers in the U. S. use about 450 billion kilograms of pesticides every year, so most of the rivers and streams in the U. S. have more chemicals that cause cancer and birth defects. In industry, many companies are causing a lot of pollution. The unwavering rate of growth of chemicals industry has seriously affected the health of not only the environment but also the population.The companies have chimneys that emit bad toxic that p ollutes the air. They also use chemicals that are bad for the environment. The chemicals have bad environmental effect on the water and ground. The environments pollution levels are important, because it can effect badly on human bodies. Air pollution can affect the ability to breath, water pollution can affect human health, and lastly the ground pollution can affect all sorts of different cancers, such as lymph node cancer and stomach cancer. Correspondingly, the companies also occupy many places where animals and plants live.The projects remedy roads and highways between beautiful greenwood and virgin forest. Therefore, with decreasing forests, people face to increase the gas of nose candy dioxide that there are not enough plants to absorb it. According to Chennal (2012), as many as three hundred volunteers from Youth Exnora International and HCL Technologies cleaned Marina Beach on July 4. For resolving the increasing stress on the environment and resources, and also respondin g to the ever-increasing demands of the citizens for environmental quality hold dearion and improvement in ecological environment, many organizations and campaigns is set up to protect environment.On the other hand, the modern life brings human many satisfactory things such as road and cars. tender can travel or go to other places more conveniently. They also have more convenient and entertaining things such as television, microwave, computer, and air conditioner. No one can deny that some human activities make the earth a better to live. However, these things could destroy our environment. A lot of air pollution emits to environment from electricity generation. Exhausted gas from cars and flue gas from factories also pollute the air.Besides, the natural resources that used as the main energy are not endless as we thought. Modern industries need more and more resources such as oils, gases, fuels, and water. So, people faced to the serious problems such as the shortage of fuels an d water. Human exit die of thirst if they waste water, or die of hungry if they waste the needful fuels that they need for prep food. If human are not careful about how we use the natural resources, they will lose many of them in the near future.The Earth is being changes by human-caused. Many people are still seek to protect the environment against endangerment. With practical activities such as planting trees, building national parks, protecting danger animals, etc. However, the bad influences are outweighed the good. Human activity is harming not only the Earth but also the living habitats of animals and people. In sum, people should consider carefully before doing something to minimize bad influences on the earth and protect the human life.
