Beach erosion is a huge issue for coastal areas in the U.S. and elsewhere. According to the non-profit American Shore & Beach Preservation Association (ASBPA), all beaches endure storms and other natural disturbances that cause them to lose sand, but the causes of beach erosion are not always the same.
The production of sugar has indeed taken a huge environmental toll. “Sugar has arguably had as great an impact on the environment as any other agricultural commodity,” reports the World Wildlife Fund (WWF), citing biodiversity loss as a result of the “wholesale conversion of habitat on tropical islands and on coastal areas” to grow sugar.
Solar geo-engineering is a term describing any of various techniques for reducing the amount of sunlight that reaches the Earth and its atmosphere.
Research indicates that indeed Americans girls and boys are going through puberty earlier than ever, though the reasons are unclear. Many believe our widespread exposure to synthetic chemicals is at least partly to blame, but it’s hard to pinpoint exactly why our bodies react in certain ways to various environmental stimuli.
A Fierce Green Fire is a new film documenting the rise of the modern environmental movement from the 1960s through the present day. It premiered at last year’s Sundance Film Festival and will be playing at select theaters across the country beginning in September 2013. Educators, environmental groups and grassroots activists also will be showing the film at small and large events from coast to coast over the course of the fall.
Ever since Thomas Malthus published “An Essay on the Principle of Population” in 1798, positing incorrectly that humans’ proclivity for procreation would exhaust the global food supply within a matter of decades, population growth has been a hot button issue among those contemplating humankind’s future.
The convergence of environmental awareness and consumer culture has created a whole new movement today whereby sharing is cool. Indeed, some environmentalists view sharing as key to maintaining our quality of life and our sanity in an increasingly cluttered world.
In April 2012, USA TODAY published a series entitled “Ghost Factories,” a report on an investigation into lead contaminated soil in hundreds of neighborhoods around the U.S. where lead factories once operated. The investigation addressed the lack of action taken by the U.S. Environmental Protection Agency (EPA) to test and clean up these sites despite having been warned in 2001 about the dangerous levels of lead contamination around the areas of these old facilities.
Since sea level measurements were first recorded, in 1870, global averages have risen almost eight inches. The annual rate of rise has been 0.13 inches over the past 20 years, which is close to twice the average from the previous 80 years. Future estimates for sea levels vary according to region but most Earth scientists agree that sea levels are expected to rise at a greater pace than during the last 50 years.
Americans are becoming increasingly concerned about global warming even as Washington politicians continue to debate whether or not to mandate emissions cutbacks. In lieu of federal action, some states and municipalities are taking action on their own to reduce fossil fuel use and greenhouse gas emissions.
If by pollution you mean greenhouse gas emissions, then definitely yes. According to Maria Diuk-Wasser at the Yale School of Public Health, the onset of human-induced global warming is likely to increase the infection rates of mosquito-borne diseases like malaria, dengue fever and West Nile virus by creating more mosquito-friendly habitats.
In what’s being billed as the greatest environmental initiative of his presidency, Barack Obama announced on June 25, 2013 that his administration is instituting stringent mandatory restrictions on greenhouse gas emissions by power plants, factories and other industrial sources. These sources combined account for roughly 40 percent of all greenhouse gas emissions across the U.S. The goal is to reduce overall greenhouse gas emissions nationally by four percent below 1990 levels within the next seven years.
While it is true that habitat loss as a result of human encroachment is a primary threat to birds and wildlife of all kinds, outdoor cats are no doubt exacerbating the loss of biodiversity as their numbers swell and they carry on their instinctual business of hunting.
Organic production may still represent only a small fraction of agricultural sales in the U.S. and worldwide, but it as been growing rapidly over the last two decades.
The monarch butterfly, royally adorned in black, white and reddish-orange and able to migrate as far as 2,800 miles, is a true wonder of nature. Each year monarchs travel from Canada and the U.S. to hibernate in the forests of central Mexico. But in recent years the monarchs have been in sharp population decline due to habitat loss, eradication of the plants it depends upon and other environmental factors.
