Environment

The natural environment, commonly referred to simply as the environment, is all living and non-living things that occur naturally on Earth or some part of it (e.g. the natural environment in a country). This includes complete ecological units that function as natural systems without massive human intervention, including all vegetation, animals, microorganisms, rocks, atmosphere and natural phenomena that occur within their boundaries. And it includes 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 human activity.

Global Warming Forum Discussion
Global warming is the increase in the average temperature of the Earth's near-surface air and oceans since the mid-twentieth century and its projected continuation. Increasing global temperature will cause sea level to rise, and is expected to increase the intensity of extreme weather events and to change the amount and pattern of precipitation. Other effects of global warming include changes in agricultural yields, trade routes, glacier retreat, species extinctions and increases in the ranges of disease vectors. Let's be serious on global warming issue and discuss here about solutions.
Effects of the automobile on societies
Over the course of the 20th century, the automobile rapidly developed from an expensive toy for the rich into the de facto standard for passenger transport in most developed countries. In developing countries, the effects of the automobile have lagged, but are emulating the impacts of developed nations. The development of the automobile built upon the transport revolution started by railways, and like the railways, introduced sweeping changes in employment patterns, social interactions, infrastructure and goods distribution. The effects of automobiles on everyday life have been a subject of controversy. While the introduction of the mass-produced automobile represented a revolution in mobility and convenience, the modern consequences of heavy automotive use contribute to the use of non-renewable fuels, the generating of air and noise pollution, and the facilitating urban sprawl and urban decay.
Species Extinction Forum Discussion
A species becomes extinct when the last existing member of that species dies. Extinction therefore becomes a certainty when there are no surviving individuals that are able to reproduce and create a new generation. A species may become functionally extinct when only a handful of individuals survive, which are unable to reproduce due to poor health, age, sparse distribution over a large range, a lack of individuals of both sexes (in sexually reproducing species), or other reasons. Pinpointing the extinction (or pseudoextinction) of a species requires a clear definition of that species. If it is to be declared extinct, the species in question must be uniquely identifiable from any ancestor or daughter species, or from other closely related species. Extinction of a species (or replacement by a daughter species) plays a key role in the punctuated equilibrium hypothesis of Stephen Jay Gould and Niles Eldredge.
Genetic Pollution Deterioration Swamping Aggression Forum Discussion
Genetic pollution is undesirable gene flow into wild populations. The term is usually associated with the gene flow from a genetically engineered (GE) organism (or genetically modifed organism - GMO) to a non GE organism; however, conservation biologists sometimes use it to describe gene flow from a domestic, feral, non-native or invasive species to a wild population. The term genetic pollution was popularized by environmentalist Jeremy Rifkin in his 1998 book The Biotech Century. While intentional crossbreeding between two genetically distinct varieties is described as hybridization with the subsequent introgression of genes, Rifkin used genetic pollution to describe the risks that might occur due the unintentional process of genetically modified organisms (GMOs) dispersing their genes into the natural environment by breeding with wild plants or animals. Whether genetic pollution or similar terms, such as “genetic deterioration”, “genetic swamping”, “genetic takeover” and “genetic aggression”, are an appropriate scientific description of the biology of invasive species is debated.
Nuclear Fallout Nuclear Meltdown Nuclear Power Forum Discussion
Nuclear safety covers the actions taken to prevent nuclear and radiation accidents or to limit their consequences. This covers nuclear power plants as well as all other nuclear facilities, the transportation of nuclear materials, the use and storage of nuclear materials for medical, power, industry, and military uses. In addition, there are safety issues involved in products created with radioactive materials. Some of the products are legacy ones (such as watch faces), others, like smoke detectors, are still being produced. Nuclear weapon safety, as well as the safety of military research involving nuclear materials, is generally handled by separate agencies than civilian safety, for various reasons, including secrecy.
