It can be measured by the ecological footprint, a resource accounting approach which compares human demand on ecosystems with the amount of planet matter ecosystems can renew. Estimates by the Global Footprint Network indicate that humanity's current demand is 70% [ 27 ] higher than the regeneration rate of all of the planet's ecosystems combined.
Environmental enrichment affects cognition and intellectual development from a neurobiological perspective. More stimulating environments can increase the number of synapses in the brain which increases synaptic activity. In humans this is most likely to occur during the development of the brain but can also occur in adults.
Environmental health was defined in a 1989 document by the World Health Organization (WHO) as: Those aspects of human health and disease that are determined by factors in the environment. [3] It is also referred to as the theory and practice of accessing and controlling factors in the environment that can potentially affect health. [4]
Although biodiversity loss can be monitored simply as loss of species, effective conservation demands the protection of species within their natural habitats and ecosystems. Following human migration and population growth, species extinctions have progressively increased to a rate unprecedented since the Cretaceous–Paleogene extinction event.
Environmental impact design impacts can be broken down into three types: Direct impacts: caused by the project and building process, such as land consumption , erosion and loss of vegetation. Indirect impacts: side-effects of a project such as degradation of surface water quality from erosion of land cleared as a result of a project.
Ecological footprints therefore track how much biocapacity is needed to provide for all the inputs that human activities demand. It can be calculated at any scale: for an activity, a person, a community, a city, a region, a nation, or humanity as a whole. Footprints can be split into consumption categories: food, housing, and goods and services.
The Bronfenbrenner ecological model examines human development by studying how human beings create the specific environments in which they live. In other words, human beings develop according to their environment; this can include society as a whole and the period in which they live, which will impact behavior and development.
Ecologically sustainable development is the environmental component of sustainable development.It can be achieved partially through the use of the precautionary principle; if there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation.
