Re: Environmentalism 101: What you need to know to do your part

Overwhelming, isn't it, trying to decide where to start to improve the environment? Maybe this Environmentalism 101 starter check list will help.

put your retirement savings into a fund that invests in environmentally sound companies and start ups


use public transportation and work for clean transportation with your town or city (low emission buses, bike paths, etc.) work on national level for a national public transportation system and lowering of emissions from travel (lower speed limits, regular service stops for electric cars, etc.)

coordinate system between farmers and city customers:for local farmers to sell their produce, eggs, etc. in the inner city regions that have no access to fresh foods

stop building of parking lots, malls, box stores, etc. Put into place new green areas with plants and design that require lowest need for water

each week take one step forward in making your home and life more sensitive to the environment such as: Start using non phosphate clothes detergent; place solar panels on your roof for water heater, write a letter to your congressional representative on environmental topic. After one year and 52 steps forward: enjoy your progress!

How to make a black hole

Here's the science of black holes, from supermassive monsters to ones the size of ping-pong balls.

  • There's more than one way to make a black hole, says NASA's Michelle Thaller. They're not always formed from dead stars. For example, there are teeny tiny black holes all around us, the result of high-energy cosmic rays slamming into our atmosphere with enough force to cram matter together so densely that no light can escape.
  • CERN is trying to create artificial black holes right now, but don't worry, it's not dangerous. Scientists there are attempting to smash two particles together with such intensity that it creates a black hole that would live for just a millionth of a second.
  • Thaller uses a brilliant analogy involving a rubber sheet, a marble, and an elephant to explain why different black holes have varying densities. Watch and learn!
  • Bonus fact: If the Earth became a black hole, it would be crushed to the size of a ping-pong ball.

Project 100,000: The Vietnam War's cruel and deadly experiment

Military recruits are supposed to be assessed to see whether they're fit for service. What happens when they're not?

  • During the Vietnam War, Robert McNamara began a program called Project 100,000.
  • The program brought over 300,000 men to Vietnam who failed to meet minimum criteria for military service, both physically and mentally.
  • Project 100,000 recruits were killed in disproportionate numbers and fared worse after their military service than their civilian peers, making the program one of the biggest—and possibly cruelest—mistakes of the Vietnam War.

China’s artificial sun reaches fusion temperature: 100 million degrees

In a breakthrough for nuclear fusion research, scientists at China's Experimental Advanced Superconducting Tokamak (EAST) reactor have produced temperatures necessary for nuclear fusion on Earth.

Surprising Science
  • The EAST reactor was able to heat hydrogen to temperatures exceeding 100 million degrees Celsius.
  • Nuclear fusion could someday provide the planet with a virtually limitless supply of clean energy.
  • Still, scientists have many other obstacles to pass before fusion technology becomes a viable energy source.
