Definitions:

Environment  - the surroundings or conditions in which a person, animal, or plant lives or operates. The natural world, as a whole or in a particular geographical area, is significantly affected by human activity.

Biomes -  fundamental units of biology and ecology, representing globally significant life patterns across the biosphere.  In the classic definition of biomes, these are tropical rainforests, grasslands, deserts and other ecosystems defined by global patterns in climate.

Natural and anthropogenic Biomes - describe the terrestrial biosphere in its contemporary, human-altered form using global ecosystem units defined by sustained direct human interaction patterns. Anthropogenic Biomes, or Human Biomes, are the globally significant ecological patterns created by sustained interactions between humans and ecosystems, including the urban, village, cropland, rangeland and seminatural anthromes.

Land cover change- These processes may include deforestation, the expansion and intensification of agriculture, rangeland modification, land and soil degradation, irrigation, land drainage, land reclamation, urban development and mining.

Ecosystem structure and dynamics - Ecosystem dynamics is the study of the changes in ecosystem structure caused by environmental disturbances or internal forces. Various research methodologies measure ecosystem dynamics.

Biodiversity loss - refers to the decline or disappearance of biological diversity, understood as the variety of living things that inhabit the planet, its different levels of biological organisation and their genetic variability as the natural patterns present in ecosystems. Biodiversity loss includes the worldwide extinction of other species, as well as the local reduction or loss of species in a particular habitat, resulting in a loss of biological diversity, described as the loss of life on Earth at various levels, ranging from reductions in the genetic diversity to the collapse of entire ecosystems.

Climate change - refers to long-term shifts in temperatures and weather patterns. These shifts may be natural, such as through variations in the solar cycle. But since the 1800s, human activities have been the main driver of climate change, primarily due to burning fossil fuels like coal, oil and gas.

Sustainability - is the ongoing capacity of the earth to maintain life. Sustainable living patterns meet the needs of the present without compromising the ability of future generations to meet their needs.
