An estimated 20 million people took to the streets across the U.S. to raise awareness about the impacts of human activities on the environment. Since then, the annual tradition has grown to involve billions of people around the world. This year, Earth Day turns 48. To mark this anniversary and to show how much has changed since 1970, we assembled 48 of the most significant accomplishments of the environmental movement since the first Earth Day. 1. 1970 "Environmental Magna Carta" The National Environmental Policy Act of 1969 went into effect the following year, becoming a landmark law that requires every major decision of the federal government to be evaluated for its impact on the environment. 2. 1972 Notorious Toxic Chemical Banned DDT (dichlorodiphenyltrichloroethane) is a colorless, nearly odorless insecticide that was widely used in the post-war era to increase farm productivity and fight mosquitoes.
Centre de ressources national sur la flore de France | Fédération des Conservatoires botaniques nationaux La constitution d’un système d’information national thématique sur la flore, la fonge, la végétation et les habitats est un préalable indispensable à l’accompagnement des politiques publiques en faveur de la conservation de la flore sauvage, des végétations et des milieux naturels et semi-naturels. La constitution d’un tel système d’information vise ainsi, en particulier, à alimenter la plateforme nationale du système d’information sur la nature et les paysages (SINP). En 2013, la FCBN s’est attachée à développer le volet « données d’observations flore » du système d’information. Le projet a pu se concrétiser grâce à une implication forte des CBN pour mettre à disposition au niveau national les données contenues dans leur système d’information. Cette intégration a nécessité, en amont, un travail conséquent de rattachement des données au format standard défini au préalable et qui prend notamment en compte le référentiel TAXREF dans sa version 5.
12 Plants That Repel Unwanted Bugs Insects have one of the most important ecological roles in nature, but you must admit that bites from mosquitoes, gnats, flies, and no-see-ums are highly annoying. To prevent their itchy and painful punctures, many people slather themselves in chemical insect spray (DEET, one of the worst offenders, is neurotoxic and has been detected in groundwater).1 They don't realize that they can repel bugs—at least partially—using the power of plants. In this article, you will learn about 12 plants that could help you manage the insect population in your garden. As a bonus, you can use most of them to make your own natural bug repellent. How Do Plants Repel Insects? The smell of some herbs and flowers, resulting from the distribution of tiny globules that contain essential oils, can help to ward off bugs. Please realize that this probably isn't enough to make your garden totally insect-free. Warning Some of the plants on this list are toxic to pets. Basil Lavender Lemongrass Lemon Thyme Mint Rosemary

Native Plants Native plants have formed symbiotic relationships with native wildlife over thousands of years, and therefore offer the most sustainable habitat. A plant is considered native if it has occurred naturally in a particular region, ecosystem, or habitat without human introduction. Exotic plants that evolved in other parts of the world or were cultivated by humans into forms that don’t exist in nature do not support wildlife as well as native plants. Occasionally, they can even escape into the wild and become invasive exotics that destroy natural habitat. Native plants help the environment the most when planted in places that match their growing requirements.
