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?

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.
