How to Recycle Plastics
The confusion over what we can and cannot recycle continues to confound consumers. Plastics are especially troublesome, as different types of plastic require different processing to be reformulated and re-used as raw material. Some municipalities accept all types of plastic for recycling, while others only accept jugs, containers and bottles stamped with certain numbers. But what do the numbers really mean, and how can consumers learn the code?

Charcoal Grills & Cancer
Nothing says summer like the smell of a backyard barbecue, but along with the aromas of meat and vegetables on the grill you may also be inhaling cancer-causing chemicals. Studies have shown that grilling over charcoal releases soot and other pollutants into the air and creates carcinogens in the smoke from the grill and the food itself.

The Ethics of Dissection
Dissecting frogs and other creatures has been a standard teaching practice in science classes for generations, but collecting amphibians, birds and other animals for dissection puts added pressure on species that are struggling to survive the habitat loss and other environmental changes. Meanwhile, some studies have shown dissection may not achieve the educational goals teachers once thought, and new digital teaching tools offer alternatives that carry no environmental consequences.

Rainforest Preservation
Preserving the Amazon rainforest in South America, as well as other rainforests worldwide, remains an important global environmental issue, even when the news media turns its attention elsewhere. Although they cover a relatively small percentage of the planet, rainforests are home to about half of the plant and animal species on Earth. Yet, according to the United Nations, at least 37.5 million acres of rainforests are lost every year. Find out more.
