Environmental Movements
The environmental movement (sometimes referred to as the ecology movement) is a social movement that aims to protect the natural world from harmful environmental practices in order to create sustainable living. In its recognition of humanity as a participant in (not an enemy of) ecosystems, the movement is centered on ecology, health, as well as human rights. The environmental movement is an international movement, represented by a range of environmental organizations, from enterprises to grassroots and varies from country to country. Due to its large membership, varying and strong beliefs, and occasionally speculative nature, the environmental movement is not always united in its goals. At its broadest, the movement includes private citizens, professionals, religious devotees, politicians, scientists, nonprofit organizations, and individual advocates like former Wisconsin Senator Gaylord Nelson and Rachel Carson in the 20th century. Since the 1970s, public awareness, enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetically Modified Crops
Genetically modified crops (GM crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering methods. Plant genomes can be engineered by physical methods or by use of '' Agrobacterium'' for the delivery of sequences hosted in T-DNA binary vectors. In most cases, the aim is to introduce a new trait to the plant which does not occur naturally in the species. Examples in food crops include resistance to certain pests, diseases, environmental conditions, reduction of spoilage, resistance to chemical treatments (e.g. resistance to a herbicide), or improving the nutrient profile of the crop. Examples in non-food crops include production of pharmaceutical agents, biofuels, and other industrially useful goods, as well as for bioremediation. Farmers have widely adopted GM technology. Acreage increased from 1.7 million hectares in 1996 to 185.1 million hectares in 2016, some 12% of global cropland. As of 2016, major crop (soybean, maize, canola and ...

Nutrition
Nutrition is the biochemistry, biochemical and physiology, physiological process by which an organism uses food and water to support its life. The intake of these substances provides organisms with nutrients (divided into Macronutrient, macro- and Micronutrient, micro-) which can be Metabolism, metabolized to create Food energy, energy and chemical structures; too much or too little of an essential nutrient can cause malnutrition. Nutritional science, the study of nutrition as a hard science, typically emphasizes human nutrition. The type of organism determines what nutrients it needs and how it obtains them. Organisms obtain nutrients by consuming organic matter, consuming inorganic matter, absorbing light, or some combination of these. Some can produce nutrients internally by consuming basic elements, while some must consume other organisms to obtain pre-existing nutrients. All forms of life require carbon, Biological thermodynamics, energy, and water as well as various other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Progressive Era
The Progressive Era (1890s–1920s) was a period in the United States characterized by multiple social and political reform efforts. Reformers during this era, known as progressivism in the United States, Progressives, sought to address issues they associated with rapid technological and industrial history of the United States, industrialization, urbanization in the United States, urbanization, immigration to the United States, immigration, and corruption in the United States, political corruption, as well as the concentration of industrial ownership in monopoly, monopolies. Reformers expressed concern about slums, poverty in the United States, poverty, and labor conditions. Multiple overlapping movements pursued social, political, and economic reforms by advocating changes in governance, scientific methods, and professionalism; regulating business; environmental protection, protecting the natural environment; and seeking to improve urban living and working conditions.

Environmental Health
Environmental health is the branch of public health concerned with all aspects of the natural environment, natural and built environment affecting human health. To effectively control factors that may affect health, the requirements for a healthy environment must be determined. The major sub-disciplines of environmental health are environmental science, toxicology, environmental epidemiology, and Environmental medicine, environmental and occupational medicine. Definitions WHO definitions Environmental health was defined in a 1989 document by the World Health Organization (WHO) as: Those aspects of human health and disease that are determined by factors in the environment. It is also referred to as the theory and practice of accessing and controlling factors in the environment that can potentially affect health. A 1990 WHO document states that environmental health, as used by the WHO Regional Office for Europe, "includes both the direct pathological effects of chemicals, r ...

Recycling
Recycling is the process of converting waste materials into new materials and objects. This concept often includes the recovery of energy from waste materials. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution (from incineration) and water pollution (from landfilling). Recycling is a key component of modern waste reduction and represents the third step in the "Reduce, Reuse, and Recycle" waste hierarchy, contributing to environmental sustainability and resource conservation. It promotes environmental sustainability by removing raw material input and redirecting waste output in the economic system. There are some ISO standards related to recycling, su ...

Reforestation
Reforestation is the practice of restoring previously existing forests and woodlands that have been destroyed or damaged. The prior forest destruction might have happened through deforestation, clearcutting or wildfires. Three important purposes of reforestation programs are for harvesting of wood, for climate change mitigation, and for ecosystem and habitat restoration purposes. One method of reforestation is to establish tree plantations, also called plantation forests. They cover about 131 million ha worldwide, which is 3% of the global forest area and 45% of the total area of planted forests. Globally, planted forests increased from 4.1% to 7.0% of the total forest area between 1990 and 2015. Plantation forests made up 280 million ha (hectare) in 2015, an increase of about 40 million ha in the previous ten years. Of the planted forests worldwide, 18% of that area consists of exotic or introduced species while the rest consist of species native to the country where they are ...

Nature Conservation
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% goal ...

Climate Crisis
''Climate crisis'' is a term that is used to describe global warming and climate change and their effects. This term and the term ''climate emergency'' have been used to emphasize the threat of global warming to Earth's natural environment and to humans, and to urge aggressive climate change mitigation and transformational adaptation. The term ''climate crisis'' is used by those who "believe it evokes the gravity of the threats the planet faces from continued greenhouse gas emissions and can help spur the kind of political willpower that has long been missing from climate advocacy". They believe, much as ''global warming'' provoked more emotional engagement and support for action than ''climate change'', calling climate change a crisis could have an even stronger effect. A study has shown the term ''climate crisis'' invokes a strong emotional response by conveying a sense of urgency. However, some caution this response may be counter-productive and may cause a backlash due t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Justice
Environmental justice is a social movement that addresses injustice that occurs when poor or marginalized communities are harmed by hazardous waste, resource extraction, and other land uses from which they do not benefit. The movement has generated hundreds of studies showing that exposure to environmental harm is inequitably distributed. Additionally, many marginalized communities, including the LGBTQ community, are disproportionately impacted by natural disasters. The movement Environmental racism in the United States, began in the United States in the 1980s. It was heavily influenced by the Civil rights movement, American civil rights movement and focused on environmental racism within rich countries. The movement was later expanded to consider gender, LGBTQ people, international environmental injustice, and inequalities within marginalized groups. As the movement achieved some success in rich countries, environmental burdens were shifted to the Global North and Global Sou ...

Environmental Protection
Environmental protection, or environment protection, refers to the taking of measures to protecting the natural environment, prevent pollution and maintain ecological balance. Action may be taken by individuals, advocacy groups and governments. Objectives include the conservation of the existing natural environment and natural resources and, when possible, repair of damage and reversal of harmful trends. Due to the pressures of overconsumption, population growth and technology, the biophysical environment is being degraded, sometimes permanently. This has been recognized, and governments have begun placing restraints on activities that cause environmental degradation. Since the 1960s, environmental movements have created more awareness of the multiple environmental problems. There is disagreement on the extent of the environmental impact of human activity, so protection measures are occasionally debated. Approaches Voluntary agreements In industrial countries, voluntary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conservation Movement
The conservation movement, also known as nature conservation, is a political, environmental, and social movement that seeks to manage and protect natural resources, including animal, fungus, and plant species as well as their habitat for the future. Conservationists are concerned with leaving the environment in a better state than the condition they found it in. Evidence-based conservation seeks to use high quality scientific evidence to make conservation efforts more effective. The early conservation movement evolved out of necessity to maintain natural resources such as fisheries, wildlife management, water, soil, as well as conservation and sustainable forestry. The contemporary conservation movement has broadened from the early movement's emphasis on use of sustainable yield of natural resources and preservation of wilderness areas to include preservation of biodiversity. Some say the conservation movement is part of the broader and more far-reaching environmental mov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
