Our Chemical Lives
Chemicals are innocent until proven guilty, chemicals are everywhere
Environmental risks to health
people are exposed to risk factors in their homes, workplaces, and communities through; air pollution, inadequate water sanitation, chemicals, radiation, community noise, occupational risks, agricultural practices, built environment, and climate change
Environmental risks to health definition
all the physical, chemical and biological factors external to person, and all related behaviors, but excluding those natural environments that cannot be reasonably modified
included
pollution
climate change
occupational risks
excluded
alcohol and tobacco consumption
diet
unemployment
Environmental Mortality and Morbidity
101 diseases have significant links to the environment
8.5 million out of 13.7 million deaths caused by the environment are due to noncommunicable diseases
Environmental Disease burden
the highest fraction of deaths and disease that could be tackled through environmental improvements is in low and middle income countries
highest burden in Africa and Southeast Asia
Ambient air pollution
broad term used to describe air pollution in outdoor environments
highest number of deaths in wealthy countries
household air pollution
in inefficient combustion of kerosene and solid fuelss from the use of open fires or poorly vented simple stoves for cooking, heating, and lighting
highest number of deaths in Africa and Southeast Asia
lowest number in wealthy countries
who is impacted by the environment
children under five and adults between 50 and 75 years old are most affected by the environment
low and middle income countries bear the greatest share of the disease burden
physical environments
air
99% of individuals breath air that exceeds the WHO’s air qualtiy standards
water
1 in 4 people lack safe drinking water
soil
erosion and pollution have led to the loss of one third of the world’s arable land over the past 40 years
soil pollution
presence of toxic chemicals in soil, in high enough concentrations to pose a risk to human health and/ or the ecosystem
some potential sources
petroleum derived products
industrial plants
mining activity
domestic, livestock, and municipal waste
natural accumulation
agricultural activities; pesticides, fertilizers, herbicides, insecticides
Pesticides and our bodies
pesticides
any substance or mixture of substances intended for preventing, destroying, repelling, or mitigating any pest
most pesticides are toxic
research as linked pesticides to
birth defects
fertility problems
neurological and mental problems
cancer
increased vulnerability among children and pregnant/ nursing women
toxins in breast milk
pesticides and disrupt body’s development
higher caloric consumption among pregnant/ nursing women, increasing level of exposure
organic food
produced by farmers who emphasize the use of renewable resources and the conservation of soil and water to enhance environmental quality for future generations
animals given no antibiotics or growth hormones
produced without pesticides
no fertilizers made with synthetic ingredients or sewage sludge
Environmental justice (organic food)
not everyone is buying organic food, including many who would like to
organic food seen as ‘vanity food’ or positional good
some people are better able to avoid effects of pesticides in food supply than others
wealthy have considerable advantage in avoiding pesticides
measures to reduce disease burden (individual)
use clean fuels in household to limit household air pollution
utilize products with no toxic chemicals
purchase local, chemical-free foods
protect skin from sun
measures to reduce disease burden (community)
increase usage of public transportation
promote safer water storage, hygiene, and sanitation
increase public health education
create healthy land use patterns - availability of parks and open spaces
measures to reduce disease burden (Societal)
regulate consumers’ exposure to chemicals
industrial emission control
small farmers need policy support to help bring down the price of organic production (instead of large industrial farms that are much more subsidized)
Hardin “Tragedy of the Commons”
the inherent logic of the commons remorselessly generates tragedy
each man is locked into a system that compels him to increase his herd without limit in a world that is limited
result is economic and environmental disaster
land erodes, grass gets thin, and sheep perish due to overgrazing
Tragedy of individualism
the inability of individuals to take a view wider than their own narrowly conceived self-interests
Normal environmentalism
environmentalism that lies behind and beneath our daily lives
walking or riding bicycle to work
buying sustainably produced food
using energy efficient appliances
we choose these options because they are cheaper, more convenient, and more enjoyable
if sustainable means a lot of extra thought then daily decisions are unlikely to be made with the environment in mind
Top down approach
additional financial resources and political influence
changes from the top down often lead to food dragging on part of those at the bottom
bottom up approach
citizen based action at the grassroots level
may lack organization and resources to accomplish tasks
democratic participation
goal
ensure that all voices are heard and are welcome, that communication is open and available to all, and that the agenda is always open to change
problems: apathy, gerrymandering, voter ID laws, polling stations
Alexis de Tocqueville
Administrate despotism
state of governance where the rules eventually hold absolute bureaucratic power resulting from the gradual, but progressive, disengagement of citizens from democracy
regulation
laws protecting individual rights, while ensuring one person’s rights don’t trample another’s
clean water act: regulates discharge of pollutants and quality standards for surface water
safe drinking water act: law that focuses on all water actually or potentially designed for drinking use, whether from above ground or underground sources
national park plastic water bottle ban
not just about government, but also organization that pattern our lives: businesses, nonprofits, churches, clubs, households, and more
Green tax
attempt to make the price of goods and services reflect their true costs and to shift the burden of government revenue generation away from regressive taxation schemes like sales taxes and value-added taxes
Finland: carbon tax
Britain: landfill tax
presently, powerful interests often get the upper hand in taxation debates
Global treaties
stockholm treaty
protects human health and the environment from persistent organic pollutants
POPs: DDT, dioxines, pesticides, hericides
the Paris Agreement
the Paris Agreement (2016)
goals
strengthen global response to the threat of climate change by keeping global temperature well below 2 degrees Celsius above pre-industrial levels
pursue efforts to liit the temperature increase even further to 1.5 degrees Celsius
strengthen the ability of countries to deal with the impacts of climate change
Nationally Determined Contributions (NDCs)
195 (of 198) parties ratified agreement so far
June 2017: US declares intentions to withdraw
February 2021: US rejoins the Paris Agreement
We are still in
over 2300 companies, 294 mayors, 412 universities, 10 governors
represents more than 159.5 million Americans
$9.46 trillion of the US economy
UN goals for sustainable development
commits stakeholders to work together to promote sustained and inclusive economic growth, social development and environmental protection and to benefit all, including women, children, youth, and future generations
green labeling
how customers know that environmental standards or dematerialization practices have been followed
FDA Organic, GMO, Fair Trade, Rainforest Alliance
verified through governments or third party certification (some of which are government backed)
concern: transferring environmental governance away from government (the people)
economic cultural shift
unite economics and ecology
canned water
plant plastic bags
bee’s wrap vs. plastic wrap
foldable metal straw
solar panel recycling facility powered by secondhand solar panels
industrial ecology
regarding pollution as a sign of inefficiency in industry

structuring real estate development so that what gets built uses land efficiently, promotes community, builds tax base, and is beautiful enough that people want to live there
build houses up not out
create zones of interaction
corner shops within walking distance
diverse housing offerings
stores, schools, and workplace near home
public transportation
environmental education
a learning process that increases people’s knowledge and awareness about the environment and associated challenges, and fosters attitudes, motivations, and commitments to make informed decisions and take responsible action
knowledge across US
many people across the US do not learn about climate change or global warming and as a result are ignorant about many of the pressing issues occuring
climate confusion among teachers
only a handful of teaches teach about climate change in their classrooms and of the teachers that teach about it only a handful of them correctly provide information to their students about how human interaction directly affect the climate
Diet
eat organic
no pesticides, herbicides, insecticides
less chemical exposure → better health of humans, wildlife, and ecosystem
find food locally grown
reduce food miles
eat heart healthy and environmentally responsible
