48 Environmental Victories Since the First Earth Day The first Earth Day, on April 22, 1970, was a milestone event for the planet. 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.

The National Gardening Association 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

Great Lakes Fishery Commission - Asian Carp Asian Carp Four species of Asian carps, bighead carp, silver carp, black carp, and grass carp, are threats to Great Lakes fisheries. Recent peer-reviewed risk assessments for bighead carp and silver carp, and grass carp indicate that the Great Lakes are at substantial risk from these three species. The primary threat from Asian carps is competition with other fish for food resources, and the likely ability of these invaders to outcompete native desirable fishes. The risk from black carp has yet to be evaluated. All four Asian carps grow to large sizes approaching or exceeding 100 lbs and four feet in length. All four Asian carps were imported to North America to assist with pest control in aquaculture facilities, and have since escaped into the wild. Because of the threat these invasive carps hold for the Great Lakes, the commission is actively working with partner agencies to prevent their introduction and establishment. For more information about Asian carps, visit asiancarp.us.
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.
