Wild-harvested seaweed can be found in very expensive packets at health boutiques, but it is abundant and free to harvest on beaches along both coasts. You can pay a handsome sum to take a seaweed harvesting workshop or do a little sleuthing and strike out on your own — it's surprisingly easy. Here are the basics.
Where
Any coastal area with rocky stretches of coastline is generally chock-full of sea vegetables. This includes virtually all of the West Coast and much of the New England coast. You'll find seaweed on the flat, sandy beaches of the Southeastern U.S., but often in more modest quantities. The most important consideration is to avoid areas of urban and industrial development, where water quality is questionable. If in doubt, contact state or county authorities for advice. It is best to contact the authorities to find out about local harvesting restrictions and whether permits are required. The rules vary widely: In Washington, a permit is required, but you're free to harvest for personal consumption up to certain limits in other states (up to 10 pounds a day in California and up to 50 pounds a day in Maine).
What Kind
No seaweed is poisonous, but some are more palatable than others. Here's a sampling of the most popular varieties.
How to Do It
You want the freshest possible seaweed, not the stuff that washed up weeks ago and is piled up in a stinking mat of debris at the high tide line. The optimal time to harvest is at low tide on a calm day, when you can safely wade into the shallows and harvest directly from the beds of living seaweed (bring water booties to protect your feet from the rocks). Using scissors or garden clippers, cut off no more than half of a given plant so that it can continue to photosynthesize. Never pull the plant up from the base. Alternatively, go to the beach after a big storm and harvest the piles of fresh seaweed that have just washed ashore.
Bringing the Harvest Home
Mesh bags are ideal for collecting and transporting seaweed, as they allow the water to drain out. If you're going to be at the beach for a while and the weather is hot, you may want to bring an ice chest to keep your harvest from becoming a slimy mass. Remove shells, stones and other loose debris. Fill a plastic tote with clean water and repeatedly dunk and swish the seaweed until all the sand has floated to the bottom of the container. To dry, simply stretch a piece of rope across a sunny area and string the seaweed along it like laundry. Store your harvest in glass jars.

Oil rigs around the world keep pulling crude oil out of the ground, but the global pandemic has sent shockwaves into the market. The supply is up, but demand has plummeted now that industry has ground to a halt, highways are empty, and airplanes are parked in hangars.
Under an agreement negotiated by community groups — represented by NRDC and the Pennsylvania Utility Law Project — the Pittsburgh Water and Sewer Authority (PWSA) will remove thousands of lead water pipes by 2026 in order to address the chronically high lead levels in the city's drinking water and protect residents' health.
Trump Administration Finalizes Car Rule Which Will Worsen Economy, Public Health
By Dave Cooke
So, they finally went and did it — the Trump administration just finalized a rule to undo requirements on manufacturers to improve fuel economy and reduce greenhouse gas emissions from new passenger cars and trucks. Even with the economy at the brink of a recession, they went forward with a policy they know is bad for consumers — their own analysis shows that American drivers are going to spend hundreds of dollars more in fuel as a result of this stupid policy — but they went ahead and did it anyway.

A blood test that screens for more than 50 types of cancer could help doctors treat patients at an earlier stage than previously possible, a new study shows. The method was used to screen for more than 50 types of cancer — including particularly deadly variants such as pancreatic, ovarian, bowel and brain.

Preliminary data from the Centers for Disease Control showed a larger number of young people coming down with COVID-19 than first expected, with patients under the age of 45 comprising more than a third of all cases, and one in five of those patients requiring hospitalization. That also tends to be the group most likely to use e-cigarettes.
