Environmental issues



Deforestation, soil erosion, and water pollution from a gold mine in Peru. Several environmental issues can result from a single activity.


By Jeremy Hance

Environmental issues are problems that impact the natural world, i.e. ecosystems, as well as the human beings who depend on them. Although environmental issues have been around since humans have (Plato complained of deforestation and resulting erosion in Greece), the modern movement concerned with environmental issues proceeded alongside, and often in response to, the rise of industrialization.

Current environmental issues include climate change, deforestation, biodiversity loss, pollution, invasive species, ecosystem destruction, ocean acidification, desertification, erosion, sprawl, fossil fuels, and overpopulation among many others.

Responses to environmental issues have included the creation of protected areas, such as national parks and wildlife reserves; laws to protect the habitat of endangered species; regulations on hunting and fishing; clean up of toxic pollution; international treaties to address global issues like depletion of the ozone layer; restoration of damaged ecosystems; reintroductions of wildlife; and others.

Since human beings are intimately connected to the environment, depending on it for clean water, food production, and breathable air, tackling environmental problems is about creating a better world for current and future generations. In recent decades, some environmental issues have moved beyond local and regional problems, to become global ones, such as climate change, mass extinction, and ocean acidification.

News on environmental issues



'A global tragedy' in the making? Thailand plans highway expansion through World Heritage Site
(08/29/2014) Dong Phayayen Khao Yai Forest Complex (DPKY-FC) is the largest tract of surviving forest in central Thailand, renowned for its biodiversity. Now, the Thai government is planning major expansions to a road that bisects the complex – which scientists say will bar animal movement throughout their natural ranges, result in higher rates of road kill, and give hunters and loggers increased access to the forest.


More trouble with tar sands: oil extraction leading to big forest loss in Alberta
(08/29/2014) Tar sands operations have been the subject of much controversy over the past few years as expected economic gains for Canada the may come at the cost of environmental damage from the proposed Keystone XL pipeline and increased greenhouse gas emissions. Now another negative impact has come to light - deforestation of the boreal forest overlying the oil deposits.


Indonesia's national airline to start using palm oil biofuel
(08/28/2014) Indonesia's national airline, Garuda Indonesia, says it will start mixing palm oil-based biofuel with its jet fuel as part of an initiative to "reduce" carbon emissions, reports The Jakarta Post.


Authorities stop 'greatest destroyers of the Brazilian Amazon rainforest'
(08/28/2014) A criminal organization involved in the illicit deforestation of large portions of Brazil's forests has been stopped, with at least six members of the organization arrested as of Aug. 28 and warrants issued for others. The gang has been accused of committing crimes worth over $220 million.


Saving the Atlantic Forest would cost less than 'Titanic'
(08/28/2014) Want to save the world's most imperiled biodiversity hotspot? You just need a down payment of $198 million. While that may sound like a lot, it's actually less than it cost to make the film, Titanic. A new study published today in Science finds that paying private landowners to protect the Atlantic Forest would cost Brazil just 6.5 percent of what it currently spends ever year on agricultural subsidies.


Indonesian authorities bust porcupine-smuggling ring
(08/28/2014) Police in Langkat, North Sumatera, Indonesia, seized 55 porcupines from smugglers preparing to ship the animals to China. Three suspects were detained during last week's operation, while their accomplices remain at large. Dozens more animals reportedly obtained from dealers in Medan are still unaccounted for.


Meeting an Illegal Logger
(08/27/2014) 'I make six times the amount of money logging as I would working my small plot of land or even working legally in a pulp and paper or palm oil plantation.' An illegal logger explains the economic conditions in South Sumatra. Mongabay Special Reporting Fellow Robert S. Eshelman interviews an illegal logger in Indonesia on the topic of cleaning up commodity supply chains.


Where should the roads go? New map offers a solution to the 'Pandora's Box of environmental problems'
(08/27/2014) Roads make it possible to bring goods to market, to get to the office, to log a forest, to hunt its wildlife. Without roads, human society as we know it could not exist. However, to build roads, trees must be cleared and swamps drained, shrinking valuable wildlife habitat and fragmenting populations in the process. A new study unveils an innovative map that defines which areas of the world would be best used to build roads – and which should be left alone.


Invasion of the lionfish: new research finds the situation may be worse than we thought
(08/27/2014) You may have recently read the controversial story on invasive lionfish research involving Dr. Zack Jud of Florida International University and a young girl named Lauren Arrington. While the issue of attribution in scientific research is crucial to the discipline, much of the media focus so far has sidestepped the real issue: what lionfish tolerance for brackish water really means for the environment.


The Gran Canal: will Nicaragua's big bet create prosperity or environmental ruin?
(08/27/2014) A hundred years ago, the Panama Canal reshaped global geography. Now a new project, spearheaded by a media-shy Chinese millionaire, wants to build a 278-kilometer canal through Nicaragua. While the government argues the mega-project will change the country's dire economic outlook overnight, critics contend it will cause undue environmental damage, upend numerous communities, and do little to help local people.
