Vector-borne Diseases & Climate Change
Climate change creates new risks, particularly in the United States, for human exposure to vector-borne diseases (VBDs) — diseases which are transmitted to humans through the bites of insects (referred to as vectors) that carry the disease-causing pathogens. Common vectors include mosquitoes, ticks, and flies.
Climate change creates new uncertainties about the spread of VBDs such as the Zika virus, dengue fever, malaria, and Lyme disease by altering conditions that affect the development and dynamics of the disease vectors and the pathogens they carry.
Earth Day & Public Health: Unavoidably Connected
Each year on April 22nd, people and nations around the world celebrate Earth Day to raise awareness and promote action toward environmental protection and sustainability. Activities typically include community clean-ups and educational campaigns designed to promote sustainability in daily life.
The origins of Earth Day date back to the 1960s and a decade of growing enviro-consciousness brought about by the publication of Rachel Carson’s Silent Spring and a series of environmental disasters that climaxed with a devastating oil spill off the coast of California in 1969. Gaylord Nelson, a U.S. Senator from Wisconsin, organized the first Earth Day in 1970, when an estimated 20 million Americans took part in organized activities ranging from tree plantings to beach cleanups and teach-ins on college campuses.
Since those humble beginnings, Earth Day has become a global event – but amidst the tree plantings and landscape revitalization lies a subtle and yet direct connection between Earth Day and Public Health. Just as we depend on the natural environment for our survival, civilization creates and shapes a social and economic environment that greatly influences the health and well-being of our species.
Under the Canopy
Journey into the largest tract of tropical rainforest on our planet — the Amazon.
Narrated by indigenous guide, Kamanja Panashekung, and actor Lee Pace, this new virtual reality film by Conservation International and Jaunt VR takes you into the Amazon and urges the protection of world’s largest rainforest.
Infographic: Carbon & The Sea
By releasing greenhouse gases into the atmosphere, humans are changing the global climate in ways that are affecting the marine environment in terms of weather patterns, water temperature, sea level, ocean chemistry, currents, coastal erosion and the frequency of storms.
Forests & Earth’s Temperatures
Seeing the forest through the trees is an expression you may not think of when the topic of global warming comes up. However, 31% of the earth’s surface is covered by trees and each one is working overtime to sequester carbon to combat global warming. Carbon sequestration is a natural or artificial process by which carbon dioxide is removed from the atmosphere and held in solid or liquid form, and it is estimated that forests absorb approximately 7.6 billion metric tons of carbon annually.
Health Impacts of Climate Change
The debate about whether climate change is a real phenomenon – and whether humankind is responsible for the alarming rise in greenhouse gas (GHG) levels – is largely a thing of the past. Three decades of research has put forth what most scientists consider incontrovertible proof that escalating levels of carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) are a direct result of human activities ranging from deforestation to emissions from energy production, industry, and agriculture.
