July 27, 2024 | Environmental Awareness | 0 comments

Every year, over 12 million people die because of unhealthy places they live or work in. Environmental pollutants cause serious health issues like breathing problems, heart disease, and some cancers. People with less money often live in dirty areas and drink unsafe water.

Children and pregnant women face a higher risk of health problems from pollution.

The National Institute of Environmental Health Sciences (NIEHS) has given over $1 billion to research on children’s environmental health. They give $100 million each year to researchers. Studies show that toxins like lead, arsenic, and air pollution harm children’s health and development.

Key Takeaways

  • Environmental pollution is a leading cause of preventable deaths worldwide.
  • Low-income communities are disproportionately affected by environmental hazards.
  • Children and pregnant women are especially vulnerable to the health impacts of pollution.
  • Significant government funding supports research into children’s environmental health.
  • Exposure to toxins like lead, arsenic, and air pollution can have serious developmental and health consequences for children.

What is Environmental Health?

Environmental health looks at how our surroundings affect our health. It focuses on the physical, chemical, and biological factors that can harm us. The goal is to find and stop things in our environment that are bad for our health.

Definition and Importance

The definition of environmental health is about studying how our environment affects our health. It’s key because it helps us live in a healthy place. Knowing about environmental health is important because things like pollution and bad chemicals can hurt our health and life quality.

Environmental Hazards and Risks

Environmental hazards are things in our environment that can harm us. These include:

  • Air pollution, like radon gas, which is the second leading cause of lung cancer in the U.S.
  • Water contamination, including lead in old pipes and paint, which can hurt major organs like the brain and liver.
  • Toxic materials, like asbestos, which can cause lung cancer and make lungs not work right when breathed in.

It’s important to find and fix these hazards to keep people healthy. By knowing the risks and acting on them, we can make healthier places. This helps people and communities live better lives.

Air Pollution: A Global Concern

Clean air is key for our health. Yet, both indoor and outdoor air pollution can harm our health. Things like dust, smoke, or tiny droplets can make the air dirty.

Being around air pollutants can hurt our health. These include things like carbon monoxide, ozone, or nitrogen oxides.

Indoor and Outdoor Air Pollution

Things like cars, factories, and fires can cause air pollution. Studies show that being around air pollution can lead to serious health issues. These include lung cancer, heart disease, and asthma in kids.

Health Impacts of Air Pollution

Air pollution can cause many health problems. These range from breathing issues to heart diseases. Fine particles in the air (PM 2.5) are especially bad because they can lead to early death.

Research also links air pollution to diabetes, obesity, and cancer.

“Almost 9 out of 10 people living in urban areas worldwide are affected by air pollution.”

Children are very sensitive to air pollution. It can harm their growing bodies. This can cause breathing problems, thinking issues, and other health problems later on.

We need to tackle air pollution from many angles. This means cutting down on emissions from cars, factories, and more. We also need good rules and health programs. By doing this, we can protect the health of people everywhere.

Water Quality and Sanitation

Safe drinking water and proper sewage are key for public health. But, germs or chemicals can get into our water from things like bad farming, sewer overflows, and industrial waste. In places like Flint, Michigan, lead contamination in water has harmed thousands of kids.

Safe Drinking Water

More people now have access to clean drinking water, going from 76% in 1990 to 91% in 2015. This means 2.6 billion more people can now get clean water. But, 663 million people still use dirty water sources, mostly in rural areas. In Africa, 44% of rural folks use dirty water.

Lead Contamination in Water Supplies

Health workers aim to cut down on things that harm our health, like making sure our water is clean. But, lead contamination in water is still a big problem. It’s a worry for schools that use well water, with 1 in 5 having high levels of contaminants.

Schools with well water having dangerous contaminant levels1 in 5

water quality

“Four out of five people living in urban areas used piped water supply in 2015, compared to two out of three in rural areas.”

The Built Environment’s Impact

Our towns and cities greatly affect our health and well-being. The design of our communities can offer both good and bad for our health. This includes how close we live to industrial and agricultural sites and if we have access to healthy food.

Proximity to Industrial and Agricultural Sites

Living near industrial or agricultural sites with poor safety can be risky. Buildings with old materials like lead pipes and asbestos can harm our health. These materials can cause serious health problems for people living nearby.

The CDC says radon can cause 3% to 14% of lung cancers. In the U.S., it leads to over 21,000 lung cancer deaths yearly.

Food Deserts and Nutrition

Having access to fresh, healthy food is key in our communities. “Food deserts” are places with few grocery stores and supermarkets. These are often in low-income areas. This makes health problems like obesity, high blood pressure, and diabetes worse.

A study found over 50% of pneumonia deaths in kids under 5 come from air pollution. This is often from cooking with solid fuels in places without clean energy.

We can make communities better for everyone’s health by understanding how our environment affects us. This means designing places that help everyone, no matter their income or where they live.

Climate Change and Environmental Health

The world is facing big challenges from climate change. This issue is making environmental health a big worry for health experts. They say that climate change will change where we can grow food like corn, soybeans, and wheat. It will also make crops grow less.

Effects on Food Production

Climate change is changing how much rain we get, making it hotter, and causing extreme weather. This can hurt how we grow food. Droughts, heatwaves, and floods can destroy crops. This leads to less food, higher prices, and more hunger, especially in poor areas.

Increased Natural Disasters and Waterborne Diseases

Climate change is making natural disasters like hurricanes, wildfires, and floods happen more often. These disasters can make people lose their homes, damage buildings, and pollute water. This increases the chance of getting waterborne diseases. Warmer weather and changing rain can also make water pathogens grow, which is bad for health, especially for kids.

Climate Change ImpactPotential Health Consequences
Disruptions to food productionFood insecurity, malnutrition, especially among children
Increased natural disastersDisplacement, infrastructure damage, water contamination, waterborne diseases
Warmer temperatures and changing precipitationGrowth of waterborne pathogens, increased risk of waterborne diseases

“Every global region is projected to experience increased frequency and intensity of extreme weather events with continued warming.”

Dealing with the effects of climate change is very important. It affects environmental health a lot. We need to work on reducing the harm to food production, natural disasters, and waterborne diseases. This will help keep kids and communities safe around the world.

How to explain environmental health to a child

Talking about environmental health with kids can be fun and important. It helps them learn to care for our planet. Start with easy ideas like clean air and water, and how trees help us.

Use stories to show how kids can make a difference. Tell them how pollution can hurt our air and water. Encourage them to recycle or plant a garden to see the impact they can have.

NASA says parents can use online tools to teach kids about climate change. For teens, talk about how climate change affects our economy and society. Encourage them to start a school club or write about climate change.

Talking about solutions can inspire kids and teens to act. The National Institute of Environmental Health Sciences has given over $1 billion to research on kids’ environmental health. They give about $100 million in grants each year for this research.

By teaching kids about environmental health in a way they can understand, we can raise a generation that cares for the planet. This will help them face the future’s challenges.

Public Health Efforts and Initiatives

Public health experts work hard to make programs and policies that help everyone’s environmental health. They focus on tracking where people are exposed to harmful substances.

Tracking Environmental Exposures

Researchers look into how environmental factors affect kids’ health. They study issues like developmental problems, diseases, and chronic illnesses later on. Programs like the NIEHS/EPA and CHEAR/HHEAR help understand these impacts.

Policies and Regulations

Strong environmental policies and rules are key to keeping us safe. For example, the EPA wants to replace all lead pipes to make water safer for those in need. Groups like the American Academy of Pediatrics also have policies on air pollution, lead prevention, and climate change effects on kids.

By using public health initiatives, tracking exposures, and making strong rules, we can protect people, especially the most vulnerable, from environmental dangers.

“Children consume more food, water, and air in proportion to their weight compared to adults, and environmental toxicants can impact a child’s development during critical windows, leading to irreversible damage.”

Environmental Justice and Health Equity

Environmental justice means everyone gets a fair shot, no matter their race, color, where they’re from, or their income. It’s about making sure everyone has a say in environmental laws and policies. Sadly, some groups face more harm from environmental dangers.

Public health experts are key in fixing these issues. They work to make sure everyone has a healthy place to live and the tools to stay well. This means:

  • Working with local people to find and fix environmental dangers;
  • Supporting laws that keep at-risk groups safe from harm;
  • Doing research to learn how environmental dangers affect certain groups;
  • Teaming up with groups to teach about environmental health and safety.

The Environmental Justice and Health Equity initiative shows how we’re tackling these big problems. Together, we can make a better future for everyone.

“Environmental justice is the fair treatment and meaningful involvement of all people, regardless of race, color, national origin, or income, with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.”

Advancing Environmental Health Equity

The National Institute of Environmental Health Sciences (NIEHS) leads in research and actions to fight environmental health disparities and support environmental justice. With programs like the Centers of Excellence on Environmental Health Disparities Research, the NIEHS aims to lessen the environmental health burdens on underprivileged groups.

By building partnerships, engaging with communities, and using solid evidence, public health workers can help make sure everyone lives in a healthy, green place. No matter who they are or where they come from.

The Role of Public Health Professionals

Public health experts are key in tackling environmental health issues. They do a lot of environmental health research. This helps them understand how the environment affects our health. They use this info to make policies and programs that keep us safe.

Evidence-Based Practices

Evidence-based practices are what public health professionals use. They aim to cut down on harmful environmental dangers. They also work to make sure everyone has access to healthy living.

This helps create places that are good for everyone’s health and life quality.

  1. They give advice to leaders and water experts on how to stop lead poisoning and talk to the community.
  2. Public health pros share info on kids’ lead levels to set goals and check progress in areas.
  3. They are trusted voices in the community. They work to lower risks for the most vulnerable, like babies.
  4. They help connect with doctors who care for kids and support plans to get funding from leaders and people in charge.
  5. They tell others how to lessen the dangers of lead in water systems.

Knowing the risks from lead in water lines and the limits of testing is key for health workers. Having safe, reliable water is vital for our health and well-being.
