No single issue can be analysed, treated, or isolated from the others. For example,
habitat loss and climate change adversely affect biodiversity. Deforestation and pollution are direct consequences of overpopulation and both, in turn, affect biodiversity. While overpopulation locally leads to
rural flight, this is more than counterbalanced by accelerating
urbanization and urban sprawl. Theories like the
world-system theory and the
Gaia hypothesis focus on the inter-dependency aspect of environmental and economic issues. Among the most evident environmental problems are: •
Overconsumption – situation where resource use has outpaced the sustainable capacity of the ecosystem. •
Overpopulation – too many people for the planet to sustain. •
Biodiversity loss •
Food waste •
Deforestation •
Desertification •
Global warming/

Habitat destruction •
Soil degradation •
