The natural environment or natural world encompasses all living and non-living 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:
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.

The pathway by which plastics enters the world's oceans
Marine plastic pollution is a type of marine pollution by plastics, ranging in size from large original material such as bottles and bags, down to microplastics formed from the fragmentation of plastic material. Marine debris is mainly discarded human rubbish which floats on, or is suspended in the ocean. Eighty percent of marine debris is plastic. Microplastics and nanoplastics result from the breakdown or photodegradation of plastic waste in surface waters, rivers or oceans. Recently, scientists have uncovered nanoplastics in heavy snow, more specifically about 3,000 tons that cover Switzerland yearly.
It is estimated that there is a stock of 86 million tons of plastic marine debris in the worldwide ocean as of the end of 2013, assuming that 1.4% of global plastics produced from 1950 to 2013 has entered the ocean and has accumulated there. Global consumption of plastics is estimated to be 300 million tonnes per year as of 2022, with around 8 million tonnes ending up in the oceans as macroplastics. Approximately 1.5 million tonnes of primary microplastics end up in the seas. Around 98% of this volume is created by land-based activities, with the remaining 2% being generated by sea-based activities. It is estimated that 19–23 million tonnes of plastic leaks into aquatic ecosystems annually. The 2017 United Nations Ocean Conference estimated that the oceans might contain more weight in plastics than fish by the year 2050. (Full article...)

The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his Kunstformen der Natur ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic movement. As a philosopher, Ernst Haeckel wrote Die Welträthsel (1895–1899; in English: The Riddle of the Universe, 1900), the genesis for the term "world riddle" (Welträtsel); and Freedom in Science and Teaching to support teaching evolution.

The Rainforest Alliance certification seal on a cup of coffee.
The Rainforest Alliance is an international non-governmental organization (NGO) with staff in more than 20 countries and operations in more than 70 countries. It was founded in 1987 by Daniel Katz, an American environmental activist, who serves as the chair of the board of directors. The NGO states that its mission is "to create a more sustainable world by using social and market forces to protect nature and improve the lives of farmers and forest communities." Its work includes the provision of an environmental certification for sustainability in agriculture. In parallel to its certification program, the Rainforest Alliance develops and implements long-term conservation and community development programs in a number of critically important tropical landscapes where commodity production threatens ecosystem health and the well-being of rural communities.
The Rainforest Alliance is a product-oriented multistakeholder governance group combining the interests of companies, farmers, foresters, communities, and consumers to produce sustainable and harmonious goods. (Full article...)

"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."
