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.
In contrast to the natural environment is the built environment. Built environments are where humans have fundamentally transformed landscapes such as urban settings and agricultural land conversion, the natural environment is greatly changed into a simplified human environment. Even acts which seem less extreme, such as building a mud hut or a photovoltaic system in the desert, the modified environment becomes an artificial one. Though many animals build things to provide a better environment for themselves, they are not human, hence beaver dams, and the works of mound-building termites, are thought of as natural.

People cannot find absolutely natural environments on Earth, and naturalness usually varies in a continuum, from 100% natural in one extreme to 0% natural in the other. The massive environmental changes of humanity in the Anthropocene have fundamentally effected all natural environments: including from climate change, biodiversity loss and pollution from plastic and other chemicals in the air and water. More precisely, we can consider the different aspects or components of an environment, and see that their degree of naturalness is not uniform. If, for instance, in an agricultural field, the mineralogic composition and the structure of its soil are similar to those of an undisturbed forest soil, but the structure is quite different.

As with many other major U.S. federal environmental statutes, the Clean Air Act is administered by the U.S. Environmental Protection Agency (EPA), in coordination with state, local, and tribal governments. EPA develops extensive administrative regulations to carry out the law's mandates. Associated regulatory programs, which are often technical and complex, implement these regulations. Among the most important, the National Ambient Air Quality Standards program sets standards for concentrations of certain pollutants in outdoor air, and the National Emissions Standards for Hazardous Air Pollutants program which sets standards for emissions of particular hazardous pollutants from specific sources. Other programs create requirements for vehicle fuels, industrial facilities, and other technologies and activities that impact air quality. Newer programs tackle specific problems, including acid rain, ozone layer protection, and climate change. (Full article...)

ZENN (Zero Emission, No Noise) is a 2-seated car that runs solely on battery. It has a range of up to 60 km and does not exceed 40 km/h. The fuel economy is few cents per kilometer and the MSRP is $12,000.
Although the company is headquartered in Canada and the car manufactured in Canada, the vehicle was first introduced in United States because at the time of vehicle's design phrase, Canadian laws prevents this car to be driven on the roads. Since 2000, British Columbia has allowed ZENN cars on its roads.
Brown is the author or co-author of over 50 books on global environmental issues and his works have been translated into more than forty languages. His most recent book is The Great Transition: Shifting from Fossil Fuels to Solar and Wind Energy (2015), in which he explains that the global economy is now undergoing a transition from fossil and nuclear energy to clean power from solar, wind, and other renewable sources. His previous book was Full Planet, Empty Plates: The New Geopolitics of Food Scarcity (2012). (Full article...)
Jungle burned to clear land for agriculture in southern Mexico.Rainforest Action Network (RAN) is an environmental organization based in San Francisco, California, United States. The organization was founded by Randy "Hurricane" Hayes and Mike Roselle in 1985, and first gained national prominence with a grassroots organizing campaign that in 1987 succeeded in convincing Burger King to cancel $31 million worth of destructive Central American rainforest beef contracts. Protecting forests and challenging corporate power has remained a key focus of RAN’s campaigns since, and has led RAN into campaigns that have led to transformative policy changes across home building, wood purchasing and supplying, automobile, fashion, paper and banking industries.

"The Wildlife Enforcement Monitoring System will provide the platform for our enforcement agencies to collect and share information on the trends and patterns of wildlife crime. Moreover, the cross-border nature of wild life crime underscores the need to enhance cooperation among our governments and to pool financial and human resources. I am confident that these measures will go a long way in enhancing our capacity to protect our wildlife resources."
