1964 In The Environment
This is a list of notable events relating to the environment in 1964. They relate to environmental law, conservation, environmentalism and environmental issues. Events January *The United States Army Corps of Engineers built a dike around the Estelline Salt Springs which caused an increase in salinity, driving many species to extinction, including '' Hemigrapsus estellinensis'' and an undescribed barnacle. April *Rachel Carson, author of the influential book ''Silent Spring'', dies at the age of 56. See also *Human impact on the environment Human impact on the environment (or anthropogenic environmental impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to ... References {{Reflist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environment (biophysical)
The natural environment or natural world encompasses all biotic and abiotic things occurring naturally, meaning in this case not artificial. The term is most often applied to Earth or some parts of Earth. This environment encompasses the interaction of all living species, climate, weather and natural resources that affect human survival and economic activity. The concept of the ''natural environment'' can be distinguished as components: * Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms, soil, rocks, plateaus, mountains, the atmosphere and natural phenomena that occur within their boundaries and their nature. * Universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water and climate, as well as energy, radiation, electric charge and magnetism, not originating from civilized human actions. In contrast to the natural environment is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Law
Environmental laws are laws that protect the environment. The term "environmental law" encompasses treaties, statutes, regulations, conventions, and policies designed to protect the natural environment and manage the impact of human activities on ecosystems and natural resources, such as forests, minerals, or fisheries. It addresses issues such as pollution control, resource conservation, biodiversity protection, climate change mitigation, and sustainable development. As part of both national and international legal frameworks, environmental law seeks to balance environmental preservation with economic and social needs, often through regulatory mechanisms, enforcement measures, and incentives for compliance. The field emerged prominently in the mid-20th century as industrialization and environmental degradation spurred global awareness, culminating in landmark agreements like the 1972 Stockholm Conference and the 1992 Rio Declaration. Key principles include the precaut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation (ethic)
Nature conservation is the ethic/moral philosophy and conservation movement focused on protecting species from extinction, maintaining and restoring habitats, enhancing ecosystem services, and protecting biological diversity. A range of values underlie conservation, which can be guided by biocentrism, anthropocentrism, ecocentrism, and sentientism, environmental ideologies that inform ecocultural practices and identities. There has recently been a movement towards evidence-based conservation which calls for greater use of scientific evidence to improve the effectiveness of conservation efforts. As of 2018 15% of land and 7.3% of the oceans were protected. Many environmentalists set a target of protecting 30% of land and marine territory by 2030. In 2021, 16.64% of land and 7.9% of the oceans were protected. The 2022 IPCC report on climate impacts and adaptation, underlines the need to conserve 30% to 50% of the Earth's land, freshwater and ocean areas – echoing the 30% ...

Environmentalism
Environmentalism is a broad philosophy, ideology, and social movement about supporting life, habitats, and surroundings. While environmentalism focuses more on the environmental and nature-related aspects of green ideology and politics, ecologism combines the ideology of social ecology and environmentalism. ''Ecologism'' is more commonly used in continental European languages, while ''environmentalism'' is more commonly used in English but the words have slightly different connotations. Environmentalism advocates the preservation, restoration and improvement of the natural environment and critical earth system elements or processes such as the climate, and may be referred to as a movement to control pollution or protect plant and animal diversity. For this reason, concepts such as a land ethics, environmental ethics, biodiversity, ecology, and the biophilia hypothesis figure predominantly. The environmentalist movement encompasses various approaches to addressing envi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Issue
Environmental issues are disruptions in the usual function of ecosystems. Further, these issues can be caused by humans (human impact on the environment) or they can be natural. These issues are considered serious when the ecosystem cannot recover in the present situation, and catastrophic if the ecosystem is projected to certainly collapse. Environmental protection is the practice of protecting the natural environment on the individual, organizational or governmental levels, for the benefit of both the environment and humans. Environmentalism is a social movement, social and environmental movement that addresses environmental issues through advocacy, legislation education, and activism. Environment destruction caused by humans is a global, ongoing problem. Water pollution also cause problems to marine life. Some scholars believe that the projected peak global population of roughly 9-10 billion people could live sustainably within the earth's ecosystems if humans worked to live ...

United States Army Corps Of Engineers
The United States Army Corps of Engineers (USACE) is the military engineering branch of the United States Army. A direct reporting unit (DRU), it has three primary mission areas: Engineer Regiment, military construction, and civil works. USACE has 37,000 civilian and military personnel, making it one of the world's largest public engineering, design, and construction management agencies. The USACE workforce is approximately 97% civilian, 3% active duty military. The civilian workforce is mainly located in the United States, Europe and in select Middle East office locations. Civilians do not function as active duty military and are not required to be in active war and combat zones; however, volunteer (with pay) opportunities do exist for civilians to do so. The day-to-day activities of the three mission areas are administered by a lieutenant general known as the chief of engineers/commanding general. The chief of engineers commands the Engineer Regiment, comprisi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Hemigrapsus Estellinensis
''Hemigrapsus oregonensis'' is a small shore crab of the family Varunidae; formerly classified under the family Grapsidae. It is known under several common names, including yellow shore crab, hairy shore crab, green shore crab, mud-flat crab, bay shore crab and Oregon shore crab. Despite its common name, the crab actually has a wide variety of coloration. It is found along the West Coast of the United States, West Coast of the United States and Canada, specifically along shorelines and similar geographical areas. In 2009, ''H. oregonensis'' was included on a list of animals petitioning for the endangered species label, but there was not enough scientific information available for it to be considered as such, so it remains unevaluated to the present day. Description This crab is an Intertidal zone, intertidal crab with wide-set eyes and no Rostrum (anatomy), rostrum. Despite its name, body color can vary. Often, the crab's rectangular-shaped carapace is deep red or brown with lig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
