7 Environmental Problems That Are Worse Than We Thought With as much attention as the environment has been getting lately, you’d think that we’d be further along in our fight to preserve the world’s species, resources and the beautiful diversity of nature. Unfortunately, things aren’t nearly that rosy. In fact, many of the environmental problems that have received the most public attention are even worse than we thought – from destruction in the rain forest to melting glaciers in the Arctic. We’ve got a lot of work to do. 7.
Soil Temperature, Seed Germination, and Why Patience is a Virtue If you are enthusiastic about growing things, you are probably already watching the weather report closely to see when you can start planting those seeds. Maybe you are even one of the lucky ones who live where the weather is already warm enough to start seriously digging in the dirt. While watching, waiting, and deciding when to plant, one of the most important factors, instead of just the weather report, is soil temperature. The weather report that you will normally receive is a reading of air temperature, normally around six feet above the ground in the shade, and while this is important for figuring out when to plant, it is important mainly because it affects the temperature of the soil, and the temperature of the soil is where it is at when planting those seeds. Soil temperature will affect the likelihood of your seeds germinating, as well as affect how quickly they will emerge.
World Energy Report (Infographic) Clean Power Published on September 30th, 2011 | by Zachary Shahan "World Energy Report" (CLICK TO ENLARGE) OK, so this isn’t an official World Energy report just released by some international energy organization or research institute, but it is a fun infographic created by some friends of ours over at MyEnergy.com that helps to visualize and convey some key energy facts. One of the most striking points (visualized with the Big Macs) is how much more energy per person the U.S. and other developed nations use compared to India, China, or the world as a whole. Here’s a good quote from the World Watch Institute on that (from State of the World 2008: Innovations for a Sustainable Economy):
MIT's artificial leaf is ten times more efficient than the real thing Speaking at the National Meeting of the American Chemical Society in California, MIT professor Daniel Nocera claims to have created an artificial leaf, made from stable and inexpensive materials, which mimics nature's photosynthesis process. The device is an advanced solar cell, no bigger than a typical playing card, which is left floating in a pool of water. Then, much like a natural leaf, it uses sunlight to split the water into its two core components, oxygen and hydrogen, which are stored in a fuel cell to be used when producing electricity. Nocera's leaf is stable -- operating continuously for at least 45 hours without a drop in activity in preliminary tests -- and made of widely available, inexpensive materials -- like silicon, electronics and chemical catalysts. It's also powerful, as much as ten times more efficient at carrying out photosynthesis than a natural leaf. Those are impressive claims, but they're also not just pie-in-the-sky, conceptual thoughts.
Fleeing Vesuvius: The psychological roots of resource over-consumption Here is my updated chapter from Fleeing Vesuvius The psychological roots of resource over-consumption Humans have an innate need for status and for novelty in their lives. Unfortunately, the modern world has adopted very energy- and resource-intensive ways of meeting those needs. Other ways are going to have to be found as part of the move to a more sustainable world. Most people associate the word “sustainability” with changes to the supply side of our modern way of life such as using energy from solar flows rather than fossil fuels, recycling, green tech and greater efficiency.
SEED STARTING TIPS & TRICKS I've been asked countless times how do you know how deep to plant seeds. A simple and very effective way to figure out how deep to plant or how much dirt to cover seeds is to gauge the SIZE of the seeds. A simple rule we follow is: "The size of the seed is how deep you cover with soil." Information and communication technologies for environmental sustainability Information and Communication Technologies for Environmental Sustainability (ICT Ensure) is a general term referring to the application of Information and Communication Technologies (ICTs) within the field of environmental sustainability. Information and Communication Technologies (ICTs) are acting as integrating and enabling technologies for the economy and they have a profound impact on our society. Recent changes in ICT use globally have impacted the environment negatively (in terms of waste and energy consumption etc) but also have the potential to support environmental sustainability activities , such as the targets set within the Millennium Development Goal (MDG) number 7 (MDG7) to “ensure environmental sustainability”. New technologies provide utilities for knowledge acquisition and awareness, early evaluation of new knowledge, reaching agreements and communication of progress in the interest of the human welfare.
Starting a Vegetable Garden, Starting a Garden Starting a vegetable garden is exhilarating, but daunting at the same time. Think of all the things you can grow! Fresh, vine-ripe tomatoes…salads that melt in your mouth…crisp, sweet carrots, straight from the earth. Imagine yourself surrounded by lush green leaves, red orbs of vine-ripe tomatoes beckoning your hand to pick them…hummingbirds and butterflies visiting flowers all around you. Makes you want to jump right in, roll up your sleeves, and get started! 101 Gardening Secrets The Experts Never Told You Please Share This Page: Google + stumbleupon tumblr
