The most controversial and political of the 10 major environmental problems is climate change. Phosphorus-nitrogen cycles, water supply, ocean acidification, pollution. There are 7 key types of pollution: air, water, soil, noise, radiation, light and thermal, and these are the main causes that affect our environment in many ways. All of these types of pollution are interrelated and mutually influence.
Therefore, we must address them all together. Air, water and soil pollution requires millions of years to recover. Exhaust gases from industry and motor vehicles are the pollutants. Heavy metals, nitrates and plastic are toxins responsible for pollution.
While water pollution is caused by oil spills, acid rain, urban runoff, air pollution is caused by various gases and toxins released by industries and factories and the combustion of fossil fuels; soil pollution is mainly caused by industrial waste that deprive the soil of essential nutrients. Globally, food security depends on the factor of whether or not soils are in good condition to produce crops. According to UN estimates, around 12 million hectares of agricultural land are severely degraded each year. Climate changes, such as global warming, are the result of human practices, such as the emission of greenhouse gases.
Global warming causes ocean and land surface temperatures to rise, causing natural disasters including floods, melting polar ice caps, rising sea levels and also unnatural precipitation patterns, such as flash floods, hurricanes, forest fires, droughts, excessive snow or desertification. Intensive agriculture practiced to produce food harms the environment through the use of chemical fertilizers, pesticides and insecticides. Overpopulation is also one of today's crucial environmental problems. Another crucial environmental problem today is the depletion of natural resources.
Human beings use so many natural resources that we would need almost 1.5 Earths to cover all our needs. This will increase even more in the future due to massive industrialization in Asian countries such as India and China. The increased use of natural resources leads to a number of other environmental problems, such as industrialization, population growth and air pollution. Over time, the depletion of natural resources will cause an energy crisis.
Chemicals emitted by many natural resources contribute to climate change. The consumption of fossil fuels causes the emission of greenhouse gases, which are primarily responsible for global warming and climate change. The enormous production of waste due to our hyperconsumption is a major threat to the environment. According to the study, the average person produces 4.3 pounds of waste per day, and the United States alone accounts for 220 million tons per year.
When this waste ends up in landfills, it generates enormous amounts of methane, which is considered one of the worst greenhouse gases due to its high global warming potential. Our forests are natural sinks of carbon dioxide and produce fresh oxygen, in addition to helping to regulate temperature and rainfall. Today, forests cover 30% of the land, but every year tree cover is lost, which the country of Panama represents due to the population's growing demand for more food, shelter and clothing. Deforestation simply means clearing green cover and making that land available for residential, industrial, or commercial purposes.
Climate change is another environmental problem that has emerged in the past two decades. It occurs due to the increase in global warming, which occurs due to the increase in the temperature of the atmosphere due to the burning of fossil fuels and the release of harmful gases by industries. A process by which it is converted or “fixed” to a more usable form is called fixation. Fixation occurs biologically and through lightning, or it can be done industrially.
People have learned to convert nitrogen gas to ammonia (NH3-) and to use nitrogen-rich fertilizers to supplement the naturally fixed amount of nitrogen. It is estimated that agriculture may be responsible for approximately 50% of nitrogen fixation in the soil by cultivating nitrogen-fixing crops and producing artificial fertilizers. When nitrogen is used more than plant demand, it can seep from soils into waterways and contribute to eutrophication. The problem can also occur during nitrification and denitrification.
Nitrous oxide (N2O) can form when the chemical process is not complete. N2O is a powerful greenhouse gas that contributes to global warming. The ozone layer is an invisible layer of protection around the planet that protects us from the sun's harmful rays. The depletion of the crucial ozone layer of the atmosphere is attributed to pollution caused by chlorine and bromide found in chlorofluorocarbons (CFCs).
Once these toxic gases reach the upper atmosphere, they create a hole in the ozone layer, the largest of which is located above Antarctica. Overfishing seriously affects natural ecosystems and leads to an imbalance in ocean life. It is estimated that around 63% of the world's fish stocks are overexploited. Overfishing caused fishing fleets to migrate to new waters, further depleting fish stocks.
Genetically modified crops can cause serious environmental problems, since a modified gene can be toxic to wildlife. However, as our environment changes, so does the need to become increasingly aware of the problems that surround it. Around the world, people are faced with a host of new and challenging environmental problems every day. Over time, the melting of polar ice caps could cause major floods, pollution of drinking water and major changes in ecosystems.
Acid rain is a known environmental problem that can have serious effects on human health, wildlife and aquatic species. The growing demand for land displaces the natural environment composed of flora and fauna, rather than being replaced. While water pollution is caused by oil spills, acid rain and urban runoff; air pollution is caused by various gases and toxins released by industries and factories and the combustion of fossil fuels, soil pollution is mainly due to industrial waste that deprives Essential nutrients to the soil. By raising awareness in your local community and in your families about these issues, you can help create a more environmentally friendly and more environmentally friendly place to live.
