It is also being acknowledged that an increasing number of ecosystems on Earth containing endangered species are disappearing. To address these issues, there have been both national and international governmental efforts to preserve Earth's wildlife.
An important aspect of energy use in livestock production is the energy consumption that the animals contribute. Feed Conversion Ratio is an animal's ability to convert feed into meat. The Feed Conversion Ratio (FCR) is calculated by taking the energy, protein, or mass input of the feed divided by the output of meat provided by the animal.
The carbon cycle is a biogeochemical cycle that is important in maintaining life on Earth over a long time span. The cycle includes carbon sequestration and carbon sinks. [4] [5] Plate tectonics are needed for life over a long time span, and carbon-based life is important in the plate tectonics process. [6]
Environmental protection has become an important task for the institutions of the European Community after the Maastricht Treaty for the European Union ratification by all of its member states. The EU is active in the field of environmental policy, issuing directives such as those on environmental impact assessment and on access to ...
Forests harbour most of Earth's terrestrial biodiversity. The conservation of the world's biodiversity is thus utterly dependent on the way in which we interact with and use the world's forests. [78] A new method used in 2011, put the total number of species on Earth at 8.7 million, of which 2.1 million were estimated to live in the ocean. [79]
Animal husbandry drives climate change, ocean acidification, and biodiversity loss, and kills 60 billion animals annually. [80] It uses between 20 and 33% of the world's fresh water, [81] Livestock, and the production of feed for them, occupy about a third of the Earth's ice-free land. [82]
The Red List of 2012 was released 19 July 2012 at Rio+20 Earth Summit; [17] nearly 2,000 species were added, [18] with 4 species to the extinct list, 2 to the rediscovered list. [19] The IUCN assessed a total of 63,837 species which revealed 19,817 are threatened with extinction.
Changing the dull creep of environmental impacts from being viewed as acceptable to being seen a reason for change to more sustainable practices. [61] Education about the necessity of family planning to slow population growth is important as greater population leads to greater human caused habitat destruction. [ 62 ]
