One of the arguments some people make when discussing human causes of climate change is that people can’t cause such massive changes. However, there is a long historical record of human-driven ecological and climatic change in Europe, North America and New Zealand, among other places.
According to the FDA, approximately three-quarters of all antibiotics used in the U.S. are fed to livestock for non-therapeutic purposes. This routine administration of antibiotics promotes the development of antibiotic-resistant bacteria, which can spread to animals and humans. And as antibiotic-resistant bacteria spreads, medicines used to treat human diseases can become less effective. Antibiotic resistant infections kill 90,000 Americans each year.
Snow leopards are majestic animals native to Central Asia. They roam the region’s rugged terrain, from Afghanistan to Kazakhstan and Russia in the north, and to India and China in the east. Snow leopards are known for their thick white coat of fur with ringed black and brown spots. These markings help camouflage the animals from their prey. But the camouflage does little to protect snow leopards from one of their biggest threats: humans.
Ebola. Hantavirus. Lyme disease. What do they have in common? Like most emerging infectious diseases, they originated in mammals. So many debilitating pathogens make the jump from wildlife and livestock to humans, yet at the global scale little is known about where people are most at risk of outbreaks.
Water is a simple chemical compound containing two hydrogen atoms and one oxygen atom connected by covalent bonds. It covers 71% of Earth’s surface and is vital for all forms of life. Despite its abundance, water that is safe for drinking is globally in short supply.
Many of us crave the scent and taste of grilled meat. Even staunch vegetarians seek out imitation meat products that simulate the look and flavor of animal protein.
One of the most troubling aspects of global climate change is its potential impact on the production, distribution and quality of food. A report issued at the 2015 Paris Climate Conference focused on identifying climate change impacts on global food security. Food security is the ability of people to obtain and use sufficient amounts of safe and nutritious food. Even without the impact of climate change, food security is a challenge because of increasing population, poverty, and changing eating habits.
Virtually everyone listening to this radio segment has relied on antibiotics to treat a bacterial infection. Since the 1940’s, we’ve used antibiotics to combat everything from strep throat to sinus infections. They also play an important role in surgery and cancer therapies.
We often talk about the importance of biodiversity in maintaining the health of ecosystems. One ecosystem we don’t often think about in those terms is the human diet.
Methane is the main component of natural gas. It is also a potent greenhouse gas, having 25 times the heat trapping ability of carbon dioxide.
In the Northeast, grilling season is almost over. While many will miss backyard barbecues, it’s high time that we rethink the American summer ideal of a thick, juicy steak.
