list four probable adverse effects on the environment.
Answers
Answer:
adverse effects on the environment are,
pollution,climate change, global warming,deforestation, overpopulation.
Explanation:
1. Pollution:
More than half of the human population knows what is pollution, but we are still not ready to face its damaging consequences. Pollution is not only limited to water, soil and noise but has extended to light, visual, point and non-point sources. Human beings and their actions are majority responsible for causing all types of pollution. Water pollution is essentially cause by oil spills, urban runoff and ocean dumping. Air pollution rises from burning of fossil fuels, hydraulic fracturing and gases emitted by vehicles. Water and soil pollution are majority cause from industrial waste.
2. Climate Change:
Climate change today is less of a natural process. It is rapidly occurring due to the ill effects of human actions responsible for disturbing and harmful out comings such as global warming, greenhouse effect, urban heat, coal industry etc.
Climate change is not only changing the overall weather scenario, but has larger and harmful effects. Some of these include: melting of polar regions, occurrence of new diseases and permanent inhibition in growth of certain plants essential for human survival.
3. Global Warming:
Global warming is another environmental issue which is increase in earth’s temperature due to effect of greenhouse gases called carbon dioxide, methane, water vapor and other gases. These gases possess heat trapping capacity that are needed to create greenhouse effect so that this planet remains warm for people to survive. Without these gases, this planet would turn be cold for life to exist.
During past several decades, the accumulation of greenhouse gases have grown rapidly, which means more heat gets trapped in the atmosphere and few of these gases escapes back into the space. These gases heat up the earth’s surface and this results in global warming. According to Environmental Protection Agency (EPA) reports, the earth’s temperature has increased by 0.8 degrees Celsius over the past century. Global warming is a serious public health and environmental concern. Global warming can have long lasting effects which can result in melting of glaciers, climate change, droughts, diseases and increase in hurricanes frequency.
4. Deforestation:
With population growing at a rapid pace, the demand for food, shelter and cloth has almost tripled in last few decades. To overcome growing demand, a direct action that we have come to recognize as “Deforestation” occurs. Deforestation means, clearing of forests or green cover for means of agriculture, industrial or urban use. It involves permanent end of forest cover to make that land available for residential, commercial or industrial purpose.
According to the United Nations Food and Agriculture Organization (FAO), an estimated 18 million acres (7.3 million hectares) of forest are lost each year. The long term effects of deforestation can be severely devastating and alarming as they may cause floods, soil erosion, increase in global warming, climate imbalance, wildlife extinction and other serious environmental issues.
5. Overpopulation:
This is a never-ending human tragedy which is responsible for causing all types of environmental issues. Water pollution, resources crisis, gender imbalance, pollution, land pollution, urban sprawling, deforestation, over production are some common examples of dangerous effects cause by overpopulation. Despite efforts taken by the government in terms of family planning in many countries, over population is difficult to control at international level. This has become more like a subjective concern and no method seems to be 100% efficient to resolve the problem of over population.
