When a reduction in CO2 emissions is requested, it is argued that it is to stop the climate change, which is true, but it is also important to know that this gas not only affects the environment, but also has a great impact on people's health.
CO2 pollution is a critical factor in the deterioration of human health. As concentrations of this gas increase in the environment, the negative effects on health become more noticeable and begin to appear more quickly. Respiratory problems, cardiovascular disorders and chronic diseases are directly associated with prolonged exposure to high levels of this polluting gas.
The impact of CO2 emissions on public health
Carbon dioxide, although generally considered a less toxic gas than other pollutants such as carbon monoxide or sulfur dioxide, has harmful effects when it accumulates in high concentrations. The relationship between CO2 emissions and public health is clear: It is linked to an increase in respiratory and cardiovascular diseases and greater vulnerability to infectious diseases.
In areas with high CO2 pollution, people are more likely to develop chronic respiratory diseases such as asthma and chronic obstructive pulmonary disease (COPD). Children and the elderly are particularly vulnerable. Continued exposure to this gas also aggravates other pre-existing conditions such as allergies and heart problems.
The relationship between CO2 and cardiovascular diseases
El thermal stress generated in areas polluted with high levels of CO2 and other greenhouse gases affects the cardiovascular system. Heat waves exacerbated by climate change increase the risk of heart attacks and other cardiovascular problems, especially among older people and those with pre-existing diseases.
Exposure to extreme heat combined with pollution can dilate blood vessels, which increases heart rate and puts pressure on the heart. This triggers a range of problems, from strokes to heart attacks. In urban areas with the 'heat island effect', where temperatures are higher due to the build-up of gases such as CO2, these types of medical emergencies are becoming more common.
Respiratory diseases and air pollution
Climate change also exacerbates respiratory problems in people. Air pollution, where CO2 contributes to the formation of Tropospheric ozone and fine particulate matter (PM10), aggravates the symptoms of asthma and other lung diseases. Changing pollen patterns, coupled with increased pollution, are lengthening the duration of allergy seasons, increasing discomfort for millions of people.
A growing number of studies, including those conducted by the WHO, directly link CO2 pollution to the increase in cases of Chronic bronchitis and COPDIn cities where CO2 levels are considerably high, an increase in hospital admissions due to severe respiratory complications has also been observed.
Policies and measures against pollution
Despite the devastating effects of CO2 and other pollutants, there are measures that can be implemented to reduce their impact. Adoption of clean technologies in industry and transport is key to reducing emissions. In many cities, sustainable mobility policies are being implemented that include promoting public transport and creating infrastructure for bicycles and non-polluting means of transport.
Another crucial factor is the improvement of energy efficiency. Better insulation and the use of renewable energy not only reduce CO2 emissions, but also decrease the population's exposure to its harmful effects on health.
Strategies for reducing CO2 in the environment
Efforts to reduce CO2 emissions should not focus solely on industry. public health policies They also play an important role in raising public awareness about the risks of pollution and in adopting habits that reduce the carbon footprint, such as a more plant-based diet or the use of clean energy sources.
The change towards a plant-based diet Not only does it have a positive impact on personal health, by reducing the risk of heart disease and diabetes, but it is also beneficial for the environment. Producing plant-based foods requires fewer resources and generates fewer greenhouse gas emissions than the production of meat and other animal products.
Individual-level measures: what you can do
In our daily lives, we can contribute to reducing CO2 and improve our health at the same time. Here are some simple actions we can all take:
- Adopt a diet rich in fruits, vegetables and plant-based foods.
- Use public transport or non-polluting means such as bicycles to get around.
- Reduce energy consumption at home by improving insulation and using renewable energy.
- Be aware of the origin and sustainability of the products we buy, prioritizing those with a lower carbon footprint.
While the task of reducing CO2 emissions globally is enormous, individual actions, when carried out on a massive scale, can have significant impacts on reducing climate damage and improving public health.
In short, we must remember that fighting against climate change and reducing CO2 emissions is not only a matter of saving the planet, but also of protecting our health and improve our quality of lifeThe measures we take today will determine the health of future generations.
