Human-caused climate changes lead to the deaths of at least 150,000
people around the world every year, a figure which
is likely to increase as global warming continues to exacerbate existing
environmental health threats around the world.
Children, the elderly, and those in disadvantaged communities are the most
vulnerable to such exacerbations. The
following expected health impacts of global climate change can be
separated into direct and indirect effects. Direct
impacts stem from extreme events such as heat waves, floods, droughts,
windstorms, and wildfires, while the indirect effects may arise from the
disruption of natural systems, causing infectious disease, malnutrition, food
and water-borne illness, and increased air pollution. Both, direct and
indirect effects, are the reasons for disasters to happen.
Answer the following questions:
Can you explain what a disaster is?
Name at least 5 natural disasters and the reasons why they happen.
Have they increased in the recent years?
Is climate change contributing to these natural disasters happening?
Can you think of any examples of man-made environmental disasters
that have taken place anywhere in the world?
How do they affect our health? (click on the link to get information
in order to answer this question) In case the link is not available here
you have the complete text.
IS CLIMATE CHANGE AFFECTING OUR HEALTH?
That’s a question I had always wondered about. When we think about climate change, or global warming, we often visualize an image like a polar bear precariously balanced on a small floating patch of ice but, in the bigger picture, can it affect our own health?
The answer is absolutely.
Unfortunately, there are many ways that are often overlooked and never even discussed when we consider climate change. The change in global temperature can have long-term effects on human health because it affects the food we eat, the
diseases we get, the disorders we develop, the air we breathe and the water we drink… all the things essential to a healthy body.
Here are just a few concerns to consider if anyone ever thinks this is only an environmental issue:
Greenhouse gasses can cause respiratory issues and more severe problems for asthma suffers because plants will actually produce more allergens when temperatures increase.
Extra heat creates more ground-level ozone,
and increases pollution, which creates addedstress for our heart and lungs.
Rising temperatures can increase the range of infectious parasites and therefore increase the rate and severity of infectious diseases.
Weather extremes will increase, resulting in intense heat waves or bouts of
bitter cold, resulting in cardiovascular and respiratory disorders.
Crops can become compromised, decreasing the yield and reducing their nutritional quality.
Water supplies are reduced along with the quality of water, coupled with an increase of water-borne illnesses.
Research has shown that bugs, plants, animals are all literally moving closer to the poles to escape the increases in heat. Tropical fish have even been found off the coast of Long Island, New York, because of the rise in water temperature.
The next time someone rejects the idea of climate change affecting their lives, remind them that our environment can’t change without changing us too!
Can we do anything to stop these natural disasters? How can we
help?
In the following pages you are going to work on this last question.
Consider the pictures bellow.
Environmental health risks you might encounter in everyday life, in
everyday places.

chemicals may affect us.
Write a brief summary of what you have discovered in Tox Town in relation
with health and how we can be affected .

WHO AM I? My name is Doreen Kukral and I'm an active and proud member of the green movement. I write a
popular blog at MomGoesGreen.com, please stop by.
WHY GO GREEN? This IS the most fundamental of questions. We each have our own idea of what “going green”
means, and perhaps, a variety of reasons for doing so. But it’s a question worth answering.
If you ever asked yourself this question, or if someone ever asks you “why”, think about the big
picture and the reasons we “do what we do”. I’m sure you’ll agree that this is a cause worth fighting
for.
1. In a nutshell, I believe the “go green” movement is all about the concerns for the depletion
and contamination of the earth’s greatest, and most important, natural resources… think
about clean water, clean air, clean soil… (not to mention a clean and healthy body). They are
directly linked to our well-being and they are in jeopardy.
2. When we choose not to recycle, our trash (that reaches landfills) contains harmful
chemicals and ingredients that affect the soil, leach into the ground and surface water, and
contaminate everything… from the soil that grows our food to the water we drink. This
contamination also creates harmful conditions for wildlife and eco-systems.
3. When we DO recycle, we save the resources needed to create new products and the
energy needed for their production, which prevents excessive CO2 emissions caused by the
production process.
4. Reducing energy consumption reduces your demand on polluting power plants that create
excessive emissions and seriously contribute to global warming.
5. Water is essential to our survival and it is NOT renewable. Being conscious of our use(and
preventing overuse) of water and seeing that we do all we can to prevent contamination of our
fresh water supply simply protects this invaluable resource.
6. Buying organic locally-grown foods means avoiding harsh chemicals, supporting agriculture
that does not contaminate the soil and food (with pesticides/herbicides and harmful chemicals),
and avoiding the emissions created by shipping produce from somewhere across the country or
(potentially) another hemisphere entirely. This, in turn, slows deforestation by reducing the
demand for producing news crops… therefore saving delicate eco-systems, valuable trees (that
hold CO2) and precious wildlife.
7. Choosing products that are biodegradable and contain natural ingredients prevents
absorption of chemicals into our own bodies and the contamination of resources when they reach
landfills and water sources. This includes everything from body products and cosmetics
to household cleaners and lawn care chemicals.
8. Choosing products made from recycled or sustainable resources does everything from
protecting resources, habitats and forests, to preventing more landfill waste, to the reduction
of production energy.
9. When we choose NOT to use resources, it SAVES resources. Is there really any reason
NOT to want to do that?
10. People, plants, animals and the environment/eco-systems are all interconnected. We
cannot change one without affecting the other and, the way I see it, we are the only “element” in
that equation that has the true ability to make a positive change.
