4 Easy Ways to Keep Your Flowers Alive Longer

Keep your flowers alive longer with these 4 easy tips. Are you tired of getting a gorgeous bouquet or buying flowers at the grocery store just to see them die within a few days? You can extend the life of your flowers for 3, 5, even 7 days by following these simple instructions. 1. Trim the stems when you get home, and every day after. First thing you should do when you get home with your flowers is to trim their stems. You can cut as much as you need to make them a nice height in your vase. Just be sure to edit out any leaves that may be touching the water as the extra foliage may have bacteria that can increase spoilage in the water. Repeat this step for as many days as you keep the flowers! 2. Change the water every day. Best practice is to dump out that old water and put in fresh, clean, cold water every day. This one small step makes a huge difference! 3. Rinse the vase, rinse the stems. Additionally, I like to rinse the vase a few times before putting in the final round of new, fresh water. This helps wash away any leftover “gunk” on that dirty rim around the vase where the water sat. I also run the flower stems under fresh water to eliminate any additional buildup! 4. Avoid extremes in temperature. Just like humans, flowers aren’t happy if they get too cold or too hot. Avoid putting your flowers in direct contact with the fan of a blowing, cold air conditioner or near a drafty door on cold winter days. Also avoid putting your flowers near overly warm places, such as on or near a heater. That’s really all it takes! These are very easy and effective steps for getting your flowers to last more than a day. No need for aspirin, flower food, or any other manmade substance. However, if you are feeling a bit experimental, add a tiny drop of bleach into the fresh water to further help ward off any bacteria. Happy flowers are freshly trimmed and watered each day. If you’re buying your own flowers, the very first step to long-lasting flowers is of course first picking healthy, strong, viable blooms. The care they’re given once you get home is also a huge factor in how long they’ll last. Always consider contacting your local florist for advice, they will be more than happy to assist.

A Paris Climate COP21 Slideshow

COP21 Paris was a very hopeful event. I was at Kyoto in 1997 and this was so much bigger and more optimistic. The whole city became a giant climate learning laboratory — there were so many events it was impossible to even know about them all. Here are some photographs for a flavor of COP21 Paris. Imagine, every nation in the world had to agree, and they did. While the agreement doesn’t do enough, the requirement to come back every 5 years and do more is so important.

What’s in the INDCs? Interactive Map

In the run up to this year’s U.N. climate conference in Paris, almost every nation in the world submitted a plan for how they will work to reduce their greenhouse gas emissions and adapt to climate change. These plans, called “Intended Nationally Determined Contributions,” or INDCs, lay out each country’s commitments, and are the starting point for climate negotiations. As of today, 185 countries, representing 97.8 percent of global emissions, have submitted such documents. So, what’s in the INDCs? According to most experts, the commitments are much better than nothing, but they still fall far short of what we need. For a more detailed reading of what each INDC says, you can read WRI’s great summary of each country’s pledges. Also, if you want to explore these documents a bit more, you can use the map below — a very basic tool that I built to search the INDCs for different words. Want to find out which country mentioned “coal” in their INDC? Or forestry? Or nuclear power? Type away below and find out. Countries whose INDCs were not in English (or who had their INDC in a format that prevented searching) are shown in light gray. Countries without an INDC are in dark gray. Obviously, this search tool won’t tell you anything about what different countries say they are going to do about coal or nuclear power. To do that, you’ll have to read the documents yourself. — This feed and its contents are the property of The Huffington Post, and use is subject to our terms.

World’s Largest Rooftop Farm Opens on the South Side of Chicago

Brooklyn-based Gotham Greens has announced the opening of their fourth greenhouse: a new facility located on Chicago’s South Side in the historic Pullman neighborhood. The rooftop of the Method Products manufacturing facility is the site of the new 75,000 square foot Chicago greenhouse, powered by 100% renewable energy. The greenhouse employs over 50 workers, including many from the Pullman community. Gotham Greens, is a producer of pesticide-free produce grown through urban agriculture. The company’s growing method is said to yield up to 30 times more crop per acre than field production, enabling the Pullman greenhouse to produce yields equivalent to over 50 acres of conventional field production. The company also recycles 100% of its irrigation water, and aims for a lighter environmental footprint by growing locally. — This feed and its contents are the property of The Huffington Post, and use is subject to our terms.

SeaWorld: Another Perspective on the Fate of Its Whales

The sentience and intelligence of killer whales is profound. This is why the notion of releasing marine park animals into nature or seaside sanctuaries via carefully coordinated soft release efforts, where animals are gradually introduced to the elements, must be carefully considered. We saw last week, that a noted orca biologist and outspoken critic of SeaWorld has been promoting controversial ecotourism programs, which offer patrons opportunities to interact with wild cetaceans. This further supports what we know about the bonding that can occur between killer whales and humans. If free-ranging marine animals are compelled to interact with humans in any capacity, depriving captive-born cetaceans of the frequent and stimulating human interaction they are used to will be devastating for them. Captive-born and captive-reared individuals of sentient species are the epitome of habituated animals and the bonds established between them and their caretakers is remarkably strong. Will killer whales raised by humans and used to daily human contact benefit more from being placed in SeaWorld’s proposed and expansive 100 million dollar enclosure or will they thrive in a seaside sanctuary exposed to a multitude of nature’s elements? It is hard to say, but the provisions SeaWorld’s Blue World exhibit will offer its killer whales much more resemble what these animals were offered at birth, as subadults, and as adult animals and I suspect they will much prefer what they are used to. Nature is both unforgiving and dangerous to a naive immune system, not to mention the dangers of exposure to degraded conditions of marine habitats as they exist today. Contaminants and debris are just a few concerns that may pose risks to these animals, which were cared for under such close supervision their entire lives. And as mentioned, limits with respect to opportunites for human contact and interaction, which are huge reinforcements for the captive-born cetacean and all captive-living marine mammals, will likely be detrimental to these animals. When I worked on reintroduction and rewildling programs for the largest terrestrial mammal in the the Western Hemisphere–the wood bison–we went to great lengths to prepare the herd for life in the wild. In the case of these large bovids, nature is not far removed from life in captivity. With that stated, and from a soft release standpoint, we can’t afford to always be gentle in a reintroduction effort because nature can be quite hostile. So we intentionally challenged animals with stressors that they may encounter in nature to condition them for a release back into the wild. I contend that SeaWorld would be negligent if they were to place captive-born animals in an ocean enclosure. If history is any indication, the sad demise of Keiko who was ultimately released into the open ocean should be an example for us. — This feed and its contents are the property of The Huffington Post, and use is subject to our terms.

McDonald’s Ready to Release Its First Organic Beef Burger

McDonald’s will release its first 100 percent organic-beef burger next week, when the “McB” joins the chain’s menu in Germany. Beginning Oct. 1, the “McB” (below) will be available in at approximately 1,500 McDonald’s in Germany. In addition to the organic beef patty, the burger has Lollo Bionda lettuce, tomatoes, pickles, red onion rings, Edam cheese and sauce. On Oct. 26, McDonald’s unveils the “Long McB” burger with organic beef, arugula, Maasdam cheese, red onion rings, tomato and a spicy sauce in a bun with sunflower seeds. The beef comes from organic farms in Germany and Austria. In announcing the debut of organic beef, McDonald’s said the suppliers and all its franchises in Germany “have been subjected to elaborate certification procedures by state-approved organic inspection bodies.” The “McB” puts Germany at the forefront of McDonald’s efforts to improve protein quality. In the U.S. it has sourced only grass-fed beef since 2010; last year it pledged to begin buying at least some verified sustainable beef (raised through socially and environmentally responsible practices) by 2016. Earlier this year, McDonald’s announced that within two years, 100% of the chicken it buys will be raised without antibiotics important to human medicine. With about 14,350 U.S. restaurants, adequate supplies of organic or antibiotic-free products take time to develop.
