One-fifth of world's plants at risk of extinction. 29 September 2010Last updated at 09:38 By David Shukman Environment correspondent, BBC News Plants such as artemisia sweet wormwood provide valuable drugs - in this case, for malaria One-fifth of the world's plants - the foundation of life on Earth - are at risk of extinction, a study concludes.
Researchers have sampled almost 4,000 species, and conclude that 22% should be classified as "threatened" - the same alarming rate as for mammals. A further 33% of species were too poorly understood to be assessed. The analysis comes from the Royal Botanic Gardens at Kew, the Natural History Museum and International Union for the Conservation of Nature (IUCN). There are an estimated 380,000 plant species in all, and many are victims of habitat loss - typically the clearing of forests for agriculture. Species in tropical rainforests are found to be at greatest risk. The study, known as the Sampled Red List Index for Plants, is an attempt to provide the most accurate assessment so far. “Start Quote. Municipal Composting by Urban Garden Center.
Municipal composting programs benefit residents, the city and the planet Municipal composting programs are sprouting up everywhere, and for good reason: the U.S.
Environmental Protection Agency estimates that close to 25 percent of solid waste in America comes from yard trimmings and food scraps. That’s a lot of bulk for already bulging city landfills. In rural areas with many small towns, county composting programs can take up the slack from settlements that don’t have the financial resources to initiate their own programs. A county compost program typically includes the same features as one managed by a municipality, so here we’ll use "city composting program" to refer to both. City composting in some areas is aided by school compost programs, in which yard and food waste is collected, processed and then sold back to residents at a reasonable cost.

Food safe way to kill aphids from herbs?? - Herbs Forum. I beg your pardon, krogers.
I find it very difficult to follow you. Who said anything about releasing beneficials? They are already there, in great abundance, as long as we don't use broad spectrum pesticides. That term ('broad spectrum pesticide') isn't mine, by the way. It's used to categorize the products we use to keep insects, diseases, and weeds at bay. Broad spectrum insecticides are simply those that can kill a wide range of insects. DE (diatomaceous earth) is a broad spectrum pesticide. Pyrethrins are also a broad spectrum pesticide family. I personally believe very strongly that we all should know how these products work, how to use them in an intelligent manner, when to use them, and what some of the successful alternatives are.
I rarely spend a dime on pest control, none so far this year. Well, except for those monarch caterpillars all over my milkweed, lol. I wish you all the best and great gardening success, krogers.
