The 4 Major Environmental Issues and Concerns of the EPA

Sep 14,  · Agriculture is the leading cause of deforestation, another one of the biggest environmental problems appearing on this list. Land is cleared to raise livestock or to plant other crops that are sold, such as sugar cane and palm oil. Apr 18,  · Climate change is a major environmental concern because of the fact that even small changes can cause significant problems for large portions of the world. Climate change is causing increase in the severity of natural disasters like floods and hurricanes worldwide. These things devastate society and wreak havoc on the regions that they danhaigh.com: Kathryn Vercillo.

The effect that humanity is having on the environment is becoming ever-more important. Through our actions we are environmejtal habitats and endangering the lives of future generations. At this point there is no denying the fact that our environment is changing. Hundreds of studies have been conducted to demonstrate that this is happening and it is having an effect on life around us. However, many may be unaware of the how to make a korker hair bow issues that have led to these changes.

To complicate the matter, many of these issues are linked to one another. The key is probleks they are all important challenges that need to be confronted. Here we examine the biggest environmental problems facing our planet today and why they should matter to you. Environmental issues caused by man-made chemicals are becoming clearer. There is also some aare that genetically-modified what do new swing state polls reveal may leak chemical compounds into soil through their roots, possibly affecting communities of microorganisms.

The average person produces 4. Much of this waste ends up in landfills, which generate enormous amounts of methane. Not only does this create explosion hazards, but methane also ranks as one of the worst of the greenhouse gases because of its high global warming potential.

Many of the issues listed here result from the massive population growth that Earth has experienced in the last century. This results in a number of issues, such as a lack of fresh water, habitat loss for wild animals, overuse of natural resources and even species what is the difference between incorporated and limited. The latter is particularly damaging, as the planet is now losing 30, species per year.

Fresh water is crucial to life on Earth, yet more sources are being polluted through human activities each year. Water pollution can have harmful effects outside of contamination of the water we drink. It also disrupts marine lifesometimes altering reproductive cycles and increasing mortality rates. The demands of an increasing population has resulted in increasing levels of deforestation.

Current estimates state that the planet is losing 80, acres of tropical forests per day. This results in loss of habitat for many species, placing many at risk and leading to large-scale extinction. The continued expansion of urban areas into traditionally rural regions is not without its problems. Urban sprawl has been linked to environmental issues like air and water pollution increases, in addition to the whhat of heat-islands.

Satellite images produced by Environmentla have also shown how urban sprawl contributes to forest fragmentation, which often leads to larger deforestation.

This has led to many fishing fleets heading to new waters, which will only serve to deplete fish stocks further. Overfishing leads to a misbalance of ocean life, severely affecting natural ecosystems in the process. Furthermore, it also has negative effects on coastal communities that rely on fishing to support their economies.

Acid rain comes as a result of air pollution, mostly through chemicals released into the environment when fuel is burned. Its effects are most clearly seen in aquatic ecosystems, where increasing acidity in the water can lead to animal deaths. It also causes various issues for trees.

Ozone depletion is caused by the release of chemicals, primarily chlorine and bromide, into the atmosphere. A single atom of either has the potential to destroy thousands of ozone molecules before leaving the stratosphere.

UVB has been linked to skin cancer and eye disease, plus it affects plant life and has been linked to a reduction of plankton in marine environments.

This increase in acidification can have dire effect on calcifying speciesmaun as shellfish. Thd causes issues throughout the food chain and may lead to reductions in aquatic life that would otherwise not be affected by acidification. Air pollution is becoming an increasingly dangerous problem, particularly in heavily-populated cities. It is also directly linked to other environmental issuessuch as acid rain and eutrophication.

Animals and humans are also at risk of developing a number of health problems due to air pollution. Continued human activities and expansion has led to lowered biodiversity. A lack of biodiversity means that future generations will have to deal with increasing vulnerability of plants to pests and fewer sources of fresh water. Some studies have found that lowered biodiversity has as pronounced an impact as climate change and pollution on ecosystems, particularly in areas with higher amounts of species extinction.

With most of the focus being placed on the carbon cycle, the effects of human use of nitrogen often slips under the radar. It is estimated that agriculture may be responsible for half of the nitrogen fixation on earth, primarily through the use and production of man-made fertilizers. Excess levels of nitrogen in water can cause issues in marine ecosystemsprimarily through overstimulation of plant and algae growth. This ;roblems result in blocked intakes and less light getting to deeper waters, damaging the rest of the marine population.

Recent studies have shown that humanity uses so many natural resources that we would need almost 1. This is only set to increase as industrialization continues in nations like China and India. ;roblems resource use is linked to a number of other environmental issuessuch as air pollution and population growth.

Over time, the depletion of these resources will lead to an energy crisis, plus the chemicals emitted by many natural resources are strong contributors to climate change. An ever-growing population aare transportation, much of which is fueled by the natural resources that emit greenhouse gases, such as petroleum.

Transportation also contributes to a range of other environmental issuessuch as the destruction of natural habitats and increase in air pollution. The issue of the melting of polar ice caps is a contentious one. While NASA studies have shown that the amount of ice in Antarctica is actually increasing, these rises only amount to a third of what is being lost in the Arctic. There is strong evidence to suggest that sea levels are risingwith the Arctic ice caps melting being a major contributor.

Over time, this could lead to extensive flooding, contamination of drinking water and major changes in ecosystems. The majority of the issues previously listed contribute or are linked to climate change. Statistics created by NASA state that global temperatures have risen by 1. The effects of climate change are widespreadas it will cause issues with deforestation, water supplies, oceans and ecosystems. Each of these have widespread implications nain their own, marking climate change as the major environmental issue the planet faces whhat.

The impact that human activities have on the environment around us is undeniable and more studies are being conducted each year to show the extent of the issue. Climate change and the many factors that contribute to emissions could lead to catastrophic issues in the future.

More needs to how to cope with revision stress done to remedy the major environmental issues that affect us today. The good news is that many of these issues can be controlled. By making adjustments, humanity can have a direct and positive impact on the environment.

#1: Gold mining.

Mar 03,  · Environmental Issue #6: Metals smelting and processing. Facilities that carry out these processes are often associated with emission of high quantities of air pollutants such as hydrogen fluoride, sulfur dioxide, oxides of nitrogen, offensive and noxious smoke fumes, vapors, gases, and other toxins. Of course, it does not end with gases.

DW looks at causes and possible solutions. Problem: Overloading of the atmosphere and of ocean waters with carbon. Atmospheric CO2 absorbs and re-emits infrared-wavelength radiation, leading to warmer air, soils, and ocean surface waters - which is good: The planet would be frozen solid without this. Unfortunately, there's now too much carbon in the air. Burning of fossil fuels, deforestation for agriculture, and industrial activities have pushed up atmospheric CO2 concentrations from parts per million ppm years ago, to about ppm today.

That's an unprecedented rise, in both size and speed. The result: climate disruption. Carbon overloading is only one form of air pollution caused by burning coal, oil, gas and wood. The World Health Organization recently estimated that one in nine deaths in were attributable to diseases caused by carcinogens and other poisons in polluted air.

Solutions: Replace fossil fuels with renewable energy. Reduce emissions from agriculture. Change industrial processes. The good news is that clean energy is abundant - it just needs to be harvested. Many say a percent renewable-energy future is feasible with existing technology now. But the bad news is that even though renewable energy infrastructure - solar panels, wind turbines, energy storage and distribution systems - are already widespread, and getting cheaper and more efficient all the time, experts say we're not applying them quickly enough to prevent catastrophic climate disruption.

Barriers in policy and finance remain to be overcome. Ulan Bator is not only one of the coldest capitals on earth, it's also a city with massive air pollution. The Chinese capital has been suffering from smog so heavy that scientists say the city is almost uninhabitable - although it is home to 20 million people. Models suggest that 3. Having said this, it might be a surprise to learn that smog is an even bigger problem in other cities across the world.

Air pollution is one of Pakistan's main environmental concerns. The situation is particularly dramatic in the country's second largest city, Lahore. The smog is caused primarily by the high volume of road traffic, rubbish incineration and dust from the surrounding deserts. In the nearly 10 million-strong city of New Delhi, the number of cars has increased from , to 3. Still, it's the city's coal powered plants that are causing the biggest problem.

They contribute to around 80 percent of the total air pollution in the city. Sandstorms, like here in Riyadh, can contribute to smog forming because they increase the amount of particles in the air. In a place like Saudi Arabia, the intense ultra-violet rays also transform transport and industry emissions into ozone.

The poor air quality in Cairo causes a number illnesses among city residents, like chronic respiratory problems and lung cancer. The reason for the air pollution is an increase in road traffic and the booming industrial sector. According to a study by the Max-Planck Institute in Mainz, some 15, people die every year in Dhaka due to air pollution.

Researchers found the world's highest concentration of sulfur dioxide there. Even if it looks the same the world over, smog is different, depending on the city.

Smog in Moscow, for instance, is characterized by high amounts of hydrocarbons. The westerly winds which regularly plow across Moscow mean that the western part of the city generally has better air quality. The smog in Mexico City is made worse by the geographical location.

The city is surrounded on three sides by mountains. Due to the high levels of sulfur dioxide and hydrocarbons in the air, Mexico City was long considered one of the most polluted cities in the world. The situation is now improving due to new transport policies and certain factories being shut down. Problem: Species-rich wild forests are being destroyed , especially in the tropics, often to make way for cattle ranching, soybean or palm oil plantations, or other agricultural monocultures.

Today, about 30 percent of the planet's land area is covered by forests - which is about half as much as before agriculture got started around 11, years ago. About 7. Tropical forests used to cover about 15 percent of the planet's land area; they're now down to 6 or 7 percent. Much of this remainder has been degraded by logging or burning. Not only do natural forests act as biodiversity reserves, they are also carbon sinks, keeping carbon out of the atmosphere and oceans.

Solutions: Conserve of what's left of natural forests, and restore degraded areas by replanting with native tree species. This requires strong governance - but many tropical countries are still developing, with increasing populations, uneven rule-of-law, and widespread cronyism and bribery when it comes to allocating land use. In , some 27, square kilometers went up in flames — a global negative record. Intensified soy and wheat cultivation are partly to blame for the destruction of the rainforest.

Destruction there rose by percent between August and June , according to the Imazon Institute. Near the city of Novo Progresso alone, some hectares of forest were torched. The Teles Pires hydropower plant on the Amazon tributary of the same name is due to start operation in Once it is cleared, the timber is sold. The illegally cleared areas in the Amazon region are often used by cattle breeders as pasture land.

The costs of clearing a forested area are estimated at around 3, euros 4, US dollars per hectare. This settler has been caught red-handed by the police. He illegally cut down trees in Jamanxim National Park. In , the agency issued fines of roughly half a billion euros. This year, the figure is likely to be even higher. Last year, the Brazilian government announced it would limit the destruction of the rainforest until to less than 4, square kilometers per year by increasing patrols.

But an ever-growing number of trees is lost to lumberjacks, gold diggers and agricultural companies. The illegally felled jungle giant pictured here was discovered near the city of Novo Progresso in Jamanxim National Park.

Humble bars along the 'Transamazonica,' like this one, are the first port of call for truck drivers and those seeking their luck in the jungle. In the rainy season, the highway often turns into an impassable mud track. Small farmers and gold prospectors have settled along the gash cut through the jungle, pushing out the original inhabitants from their traditional areas of settlement.

The gold rush is threatening their lives. Hundreds of Yanomami have died from diseases brought into their areas by prospectors. In June this year, the Brazilian army destroyed illegal airstrips in the nearly 9. Black gold: In the middle of the 'Alto Rio Guama' reservation, jungle giants like these disappear in round ovens. The illegally felled trees are turned into charcoal. This aerial image was taken from a police helicopter during a patrol in September Problem: On land, wild animals are being hunted to extinction for bushmeat, ivory, or "medicinal" products.

At sea, huge industrial fishing boats equipped with bottom-trawling or purse-seine nets clean out entire fish populations. The loss and destruction of habitat are also major factors contributing to a wave of extinction - unprecedented in that it is caused by a single species: humans.

Not only do species inherently deserve to exist, they also provide products and "services" essential to human survival. Think bees and their pollinating prowess - necessary for growing food. Solutions: Concerted efforts need to be made to prevent further loss of biodiversity. Protecting and restoring habitats is one side of this - protecting against poaching and wildlife trade is another. This should be done in partnership with locals, so that wildlife conservation is in their social and economic interest.

The American black bear is one of more than 22, species threatened with extinction. During the past century, animals have been disappearing about times faster than they used to, scientists from different American universities warned in a new study.

According to the WWF, around 70 species go extinct every day. According to the International Union for Conservation of Nature - which publishes a "red list" of threatened and endangered species - 41 percent of amphibian species and 26 percent of mammals are facing extinction. This Titicaca water frog, found only in Lake Titicaca in South America, used to be present in the millions in the early s. By now, they have disappeared almost completely. The causes of species loss are mostly manmade.

They range from climate change, to pollution, to deforestation and beyond. About 2, trees have been cut down every minute during the past 40 years, according to a different study. The world is embarking on its sixth mass extinction event, the current study concludes. The modern rate of species loss was compared to "natural rates of species disappearance before human activity dominated.

The study is based on documented extinctions of vertebrates - or animals with internal skeletons - from fossil records and other historical data. These results are estimations, since humans don't know exactly what happened throughout the course of Earth's history. In earlier extinction events, such as the Ice Age, only two out of 10, mammals died out per century - such as this primordial horse. As species disappear, so do crucial services, such as pollination of crops by honeybees.

At the current rate of species loss, humans will lose innumerable biodiversity benefits within three generations, the study's authors write. If the current rate of extinction is allowed to continue, "life would take many millions of years to recover and our species itself would likely disappear early on," wrote lead author Gerardo Ceballos of the Universidad Autonoma de Mexico.
