FAQs about Environment

1. What is the environment and what is its importance?

The environment is the space in which biotic elements (living beings) develop, surrounded by abiotic or inanimate elements. Among these are air, water, soil, a variety of substances, fluids, energy, and other physical and chemical phenomena. It also includes everything manufactured, built or discarded by human beings. As a whole, the environment is a huge and fragile system, especially since the rapid intervention of the planet by Homo sapiens.

The natural environment

The natural environment includes living and non-living beings on Earth, excluding those built by Homo sapiens. In it all the species on the planet interact, air, water, soil, natural fire, climate, energy, radiation and all-natural phenomena that affect them. Today the natural environment is a theoretical concept, since in practice there is almost no place on the planet without the human footprint, such as engineering works, agriculture, livestock and a number of objects and constructions made by men and women.

The built environment

The built environment contains the elements manufactured or built by humans in ancient natural spaces. These human actions have been carried out most of the time at the expense of ecosystems that have been partially or totally eliminated so that Homo sapiens can ensure their habitat, supply and recreation. Among them cities, towns, housing estates, houses, fields, livestock, factories, dams, aqueducts, ports, airports, underground transport, roads, highways, power plants, hydroelectric dams, green areas, theme parks and shopping centers within or outside the cities.

Importance of the environment

By its definition, the environment is inseparable from life. Therefore, on uninhabited planets there can be no environment, this being a privilege of our planet Earth.

World Environment Day

The date of this celebration was proclaimed by the United Nations General Assembly in 1972, coinciding with the beginning of the First Earth Summit or Stockholm Conference, whose main theme was just the environment.

June 5 was established as World Environment Day by the United Nations General Assembly in 1972. On that date, the Stockholm Conference “First Earth Summit” was held at the initiative of Sweden and in conjunction with the UN.
This year’s World Environment Day will be hosted by Pakistan. The theme of the year is “Restoration of ecosystems”, and the motto is “Reimagine, recreate, restore.” It will be in this environment that the United Nations Decade on Ecosystem Restoration 2021-2030 is launched.

World Environment Day is celebrated on June 5 of each year. In 2020 the venue of the event will be Colombia. Topics to be discussed will be the Amazon, air quality, health, circular economy, and climate change. The central theme is  “Conservation of biodiversity” and the motto “Time for Nature”. The environment is the space that sustains biodiversity and therefore life on Earth. By its definition, an environment cannot exist on a planet devoid of life since its statement implies the relationship of living beings with their environment.

Beat Air Polution

World Environment Day is celebrated on June 5, dedicated this year to the fight against air pollution with the moto “Beat Air pollution”. Established by the UN in 1972, during the Stockholm Conference, whose central theme was the normalization of human relations with the environment. China will be the global host of the 2019 World Environment Day. The country’s government has committed that day to organizing celebrations in many cities, with a main event in Hangzhou, Zhejiang province. In the north of China there are several cities where the air is practically unbreathable due to pollution.

Environmental pollution, in the classical concept, occurs when certain elements that cause harmful effects accumulate in quantities that nature cannot recycle. A contaminant is a substance that is found in a medium to which it does not belong or that does so at levels that can cause adverse effects. A species is in danger of extinction when its existence is globally compromised. Humans, in a short time, we have turned the Earth into a kind of supermarket where we are supplied with everything we need, including the spaces to build our towns, cities, mining camps, agricultural and livestock lands. We have wrested huge areas that recently belonged to the other species, without much regard to the damage we have caused them.
