Global Climate Change01:50

Global Climate Change

24.6K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Sustainable Development

13.4K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Dimensions of Health and Illness

7.5K
The factors influencing the health-illness continuum can be internal or external and may or may not be under conscious control. They are related to the following eight human dimensions, and each dimension is interrelated to one other.

Global Regulatory Systems01:28

Global Regulatory Systems

45
Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Primary Healthcare Services

1.4K
Primary care promotes wellness and prevents disease. This care includes health promotion, education, protection (such as immunizations), early disease screening, and environmental considerations. Settings providing this type of healthcare include physician offices, public health clinics, school nursing, and community health nursing.
In 1978, international leaders convened in Alma-Ata, Kazakhstan, for what would be a pivotal event in global health. The Alma-Ata Declaration was the first to call...

Area of Science:

  • Human behavior
  • Global economics
  • Sociology

Background:

  • Human activities are constrained by the 24-hour day.
  • Global societies and economies are highly integrated.
  • A comprehensive overview of global time allocation is lacking.

Purpose of the Study:

  • To estimate how all humans spend their time.
  • To develop a generalized, physical outcome-based categorization of human activities.
  • To provide a baseline quantification of global human time allocation.

Main Methods:

  • Utilized a generalized, physical outcome-based categorization.
  • Integrated data from hundreds of diverse datasets.
  • Estimated time allocation for various human activities.

Main Results:

  • Most waking hours (9.4 h/d) are for direct mind/body outcomes.
  • 3.4 h/d are spent modifying environments.
  • 2.1 h/d are for social processes and transportation.
  • Time for material/energy extraction (5 min/d) and waste management (1 min/d) is minimal.

Conclusions:

  • Provides a baseline quantification of global human time allocation.
  • Highlights potential for modifying time allocation in resource extraction and waste management.
  • Results can be applied to multiple fields of research.
