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.

No longer 'deaf as a stump': researchers find turtles chirp, click, meow, cluck
(07/25/2014) Turtles comprise one of the oldest living groups of reptiles, with hundreds of species found throughout the world. Many have been well-researched, and scientists know very specific things about their various evolutionary histories, metabolic rates, and the ways in which their sexes are determined. But there was one very obvious thing that has been largely left unknown by science until very recently. Turtles can make sounds.
Seafood apartments and other experiments in fixing Indonesia's fisheries (Part IV)
(07/25/2014) Shrimp farms, industrial plants, and one of Indonesia's busiest thoroughfares make up Java's north coast today. It's a very different scene from the fishing villages with beachfront boat parking that stood here decades earlier. Which begs the question, where will fish live in this new 'coast without mangroves, without coral, without seagrass,' asks Alan Koropitan, a marine biologist based at Bogor Agricultural University.
True stewards: new report says local communities key to saving forests, curbing global warming
(07/24/2014) Deforestation is compromising forests around the world, destroying vital habitat and causing greenhouse gases emissions that are contributing to global warming. A new report released today finds a possible solution: protecting forests by empowering the local communities that live within them.
A letter to Indonesia's new president on his environmental policy
(07/24/2014) Congratulations on your successful bid for the Indonesian presidency. Although neither you nor your opponent spent much time focusing on the environment, the world hopes your previous record in Surakarta (Solo) and Jakarta, coupled with the idealistic language in your campaign platform, is evidence enough of your intent to slow the rapid destruction of Indonesia's environment. It will be a long and challenging road, but the Indonesian people have entrusted their country to you based on the promises you made to them. The world looks forward to watching you enact policies that keep these promises.
It's not just extinction: meet defaunation
(07/24/2014) Get ready to learn a new word: defaunation. Fauna is the total collection of animals—both in terms of species diversity and abundance—in a given area. So, defaunation, much like deforestation, means the loss of animals in all its myriad forms, including extinction, extirpation, or population declines.
Desperate measures: researchers say radical approaches needed to beat extinctions
(07/24/2014) Today, in the midst of what has been termed the “Sixth Great Extinction” by many in the scientific community, humans are contributing to dizzying rates of species loss and ecosystem changes. A new analysis suggests the time may have come to start widely applying intensive, controversial methods currently used only as “last resort” strategies to save the word’s most imperiled species.
Next big idea in forest conservation: Reconnecting faith and forests
(07/24/2014) 'In Africa, you can come across Kaya forests of coastal Kenya, customary forests in Uganda, sacred forest groves in Benin, dragon forests in The Gambia or church forests in Ethiopia...You can also come across similar forest patches in South and Southeast Asia including numerous sacred groves in India well-known for their role in conservation of biological diversity,' Dr. Shonil Bhagwat told mongabay.com.
Targeted enforcement saved a Massachusetts-worth of Amazon rainforest in 3 years
(07/24/2014) Targeted law enforcement efforts via Brazil's green municipalities programs were responsible for reducing deforestation by 10,653 square kilometers — an area the size of Massachusetts — between 2009 and 2011, argues a paper published in the journal Land Use Policy.
Brazil could meet all its food demand by 2040 without cutting down another tree
(07/24/2014) Better utilization of its vast areas of pasturelands could enable Brazil to dramatically boost agricultural production without the need to clear another hectare of Amazon rainforest, cerrado, or Atlantic forest, argues a new study published in the journal Global Environmental Change.
Scientists ask Australia to strengthen, not weaken, protection for Great Barrier Reef
(07/24/2014) A convening of nearly 600 tropical biologists and conservation scientists has called upon the Australian government to strengthen protection of the Australia's Great Barrier Reef. The declaration, issued at the annual meeting of the Association for Tropical Biology and Conservation (ATBC), comes as Prime Minister Tony Abbott pushes to allow industrial dumping in the Great Barrier Reef Marine Park as well as port development in a nearby coastal area.
