Earth System science is the application of systems science to the Earth. In particular, it considers interactions and feedbacks, through material and energy fluxes, between the Earths sub-systems cycles, processes and "spheres" - atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, lithosphere, biosphere, and even the magnetosphere - as well as the impact of human societies on these components. At its broadest scale, Earth System science brings together researchers across both the natural and social sciences, from fields including ecology, economics, geography, geology, glaciology, ...
Ecosystem ecology is the integrated study of living and non-living components of ecosystems and their interactions within an ecosystem framework. This science examines how ecosystems work and relates this to their components such as chemicals, bedrock, soil, plants, and animals. Ecosystem ecology examines physical and biological structures and examines how these ecosystem characteristics interact with each other. Ultimately, this helps us understand how to maintain high quality water and economically viable commodity production. A major focus of ecosystem ecology is on functional processes ...
Environmental globalization refers to the internationally coordinated practices and regulations regarding environmental protection. An example of environmental globalization would be the series of International Tropical Timber Agreement treaties, establishing International Tropical Timber Organization and promoting sustainable management of tropical forests. Environmental globalization is usually supported by non-governmental organizations and governments of developed countries, but opposed by governments of developing countries which see pro-environmental initiatives as hindering their ec ...
Water scarcity is the lack of fresh water resources to meet water demand. It affects every continent and was listed in 2019 by the World Economic Forum as one of the largest global risks in terms of potential impact over the next decade. It is manifested by partial or no satisfaction of expressed demand, economic competition for water quantity or quality, disputes between users, irreversible depletion of groundwater, and negative impacts on the environment. Two-thirds of the global population live under conditions of severe water scarcity at least 1 month of the year. Half a billion people ...
Wilderness or wildlands are natural environments on Earth that have not been significantly modified by human activity or any nonurbanized land not under extensive agricultural cultivation. The term has traditionally referred to terrestrial environments, though growing attention is being placed on marine wilderness. Recent maps of wilderness suggest it covers roughly one quarter of Earths terrestrial surface, but is being rapidly degraded by human activity. Even less wilderness remains in the ocean, with only 13.2% free from intense human activity. Some governments establish protection for ...
World Environment Day is celebrated on 5 June every year, and is the United Nations principal vehicle for encouraging awareness and action for the protection of our environment. First held in 1974, it has been a flagship campaign for raising awareness on emerging from environmental issues to marine pollution, human overpopulation, and global warming, to sustainable consumption and wildlife crime. World Environment Day has grown to become a global platform for public outreach, with participation from over 143 countries annually. Each year, WED has a new theme that major corporations, NGOs, ...
