Some planners argue that modern lifestyles use too many natural resources, polluting or destroying ecosystems, increasing social inequality, creating urban heat islands, and causing climate change.

Some examples of important biodiversity and / or high endemism ecosystems are: El Yunque National Forest in Puerto Rico, Costa Rican and Nicaraguan rainforests, Brazilian and Venezuelan Amazon Rainforest territories, Madagascar dry deciduous forests, Waterberg Biosphere of South Africa and eastern Madagascar rainforests.

Some experts also recognize wet meadows and aquatic ecosystems as additional wetland types.

Some surfactants are known to be toxic to animals, ecosystems, and humans, and can increase the diffusion of other environmental contaminants.

Some draw on archaeology to cite examples of cultures they say have disappeared because they grew beyond the ability of their ecosystems to support them.

Some define ' landscape ' as an area containing two or more ecosystems in close proximity.

Some terrestrial ecosystems – for example, those of the open deserts and similar arid environments – exist on irregular rainfall and the moisture it delivers to the soil, supplemented by moisture in the air.

Some efforts have been proposed to establish species corridors, continuous or near-continuous segments of habitat through urban and surrounding areas to minimize the disturbances imposed on ecosystems by urban stress and fragmentation.

Some of the ecosystems are threatened by man, if lands aren ’ t preserved and protected all beneficial use can be lost forever.

Some primary concerns around sustainability are that heavy fishing pressures, such as overexploitation and growth or recruitment overfishing, will result in the loss of significant potential yield ; that stock structure will erode to the point where it loses diversity and resilience to environmental fluctuations ; that ecosystems and their economic infrastructures will cycle between collapse and recovery ; with each cycle less productive than its predecessor ; and that changes will occur in the trophic balance ( fishing down marine food webs ).

Some examples of ecosystems that are rich in diversity are:

Some believe that strategies of conservation, stewardship, and regeneration can be applied at all levels of scale from the individual building to the community, with benefit to the human individual and local and planetary ecosystems.

Some of the principal causes of habitat degradation and loss in these ecosystems are:

Some Lyngbya species can also temporarily monopolize aquatic ecosystems when they form dense floating mats in the water.

Some environmentalists have used " business ecosystems " as a way to talk about environmental issues as they relate to business rather than as a metaphor to describe the increasing complexity of relationships among companies.

Some oak species even continue into the surrounding ecosystems.

Some game reserves were deproclaimed and the Nagana Campaign was implemented, which caused severe degradation of ecosystems.

Some versions of conflict theory focus on the role of resource scarcity in sparking or propagating human conflicts-in effect holding that the resources or ecosystems they fight over are being held so valuable that they are worth considerable risk of harm to control.

Some organisms have adapted to live on mobile plastic debris, which has allowed the inhabitants to disperse all over the world and become invasive species in remote ecosystems.

Some uncharacteristically large wildfires in the United States have been caused as a consequence of years of fire suppression and the continuing expansion of people into fire-adapted ecosystems.

Some of the edible species of Syzygium are planted throughout the tropics worldwide, and several have become invasive species in some island ecosystems.

Some of the important abiotic environmental factors of aquatic ecosystems include substrate type, water depth, nutrient levels, temperature, salinity, and flow.

Some animals commonly found in páramo ecosystems include the Andean Fox ( also referred to as the “ Páramo Wolf ”, the White-Tailed Deer, and the Spectacled Bear which occasionally forages in the high páramo for its favorite snack, Puya bromeliads.

Some of the project objectives include the restoration of degraded forest ecosystems, enhanced biodiversity conservation, prevention of soil erosion, education of and employment opportunities for local communities, and the regeneration of vegetation on the edge of forest areas to act as a buffer to interior forests.

Some of them are obvious, such as the fact that we associate recorded and live music with our responses and behavior in different types of environments and social settings.

Some recreation features, such as scenic values and water interest, also have greater overall value than other interests.

Some areas may provide archeological values such as ancient Indian village sites or hunting areas, caves, artifacts, etcetera.

Some vocational training schools provide such training, but the current need exceeds the facilities.

Some such youngsters rarely smile, or they try to speak with the mouth closed.

Some anthropologists, such as Lloyd Fallers and Clifford Geertz, focused on processes of modernization by which newly independent states could develop.

Some, such as the spadefoot toads, have strong biting jaws and are carnivorous or even cannibalistic.

Some of these have specific adaptations such as enlarged teeth for biting or spines on the chest, arms or thumbs.

Some salamanders adopt defensive poses when faced by a potential predator such as the North American northern short-tailed shrew ( Blarina brevicauda ).

Some jurisdictions have specialized appellate courts, such as the Texas Court of Criminal Appeals, which only hears appeals raised in criminal cases, and the United States Court of Appeals for the Federal Circuit, which has general jurisdiction but derives most of its caseload from patent cases, on the other hand, and appeals from the Court of Federal Claims on the other.

Some adaptations of the Latin alphabet are augmented with ligatures, such as æ in Old English and Icelandic and Ȣ in Algonquian ; by borrowings from other alphabets, such as the thorn þ in Old English and Icelandic, which came from the Futhark runes ; and by modifying existing letters, such as the eth ð of Old English and Icelandic, which is a modified d. Other alphabets only use a subset of the Latin alphabet, such as Hawaiian, and Italian, which uses the letters j, k, x, y and w only in foreign words.

Some alphabets today, such as the Hanuno ' o script, are learned one letter at a time, in no particular order, and are not used for collation where a definite order is required.

Some of the oldest and most widespread stories in the world are stories of adventure such as Homer's The Odyssey.

Some are no more than a widening of a stream valley ; others, such as the Konya Ovasi, are large basins of inland drainage or are the result of limestone erosion.

Some of these churches are known as Anglican, such as the Anglican Church of Canada, due to their historical link to England ( Ecclesia Anglicana means " English Church ").

Some meals are communal, such as fondue, where a pot is set in the middle of the table for each person to dip into.

Some high mountain villages, such as Avoriaz ( in France ) Wengen and Zermatt ( in Switzerland ) are accessible only by cable car or cog-rail trains, and are car free.

Some belief systems, such as those in the Abrahamic tradition, hold that the dead go to a specific plane of existence after death, as determined by a god, gods, or other divine judgment, based on their actions or beliefs during life.

Some sects, such as the Universalists, believe in universalism that all souls will ultimately be saved and that there are no torments of hell.

Some, such as Francis Crick in 1994, have attempted a " scientific search for the soul ".

Some of these beliefs, such as Pelagianism and semi-Pelagianism ( see below ) are not considered to be within Arminian orthodoxy and are dealt with elsewhere.

Some Arminians, such as professor and theologian Robert Picirilli, reject the doctrine of open theism as a " deformed Arminianism ".
