Resolver a crise climática pode ser uma das mais importantes oportunidades de saúde do século XXI! Neste capítulo, analisaremos como a saúde e as mudanças climáticas estão relacionadas e porque isso é importante.

Poluição em ambientes internos e saúde

Qual porcentagem da população mundial você acha que cozinha queimando diretamente madeira, carvão vegetal, esterco animal ou carvão mineral?


A fumaça e a fuligem produzidas quando esses combustíveis são utilizados para cozinhar em ambientes internos podem causar doenças cardíacas e respiratórias, além de câncer e infartos. Por causa dessas doenças, a poluição em ambientes internos é responsável por 4,3 milhões das mortes precoces todos os anos, em sua maioria em países em desenvolvimento, como é mostrado abaixo.

Many countries face a lot of death from indoor air pollution

These traditional cooking methods also contribute 2-5% of global annual greenhouse gas emissions.These are caused by burning the fuels and deforestation to gather them.

Earthly suffering the impacts of traditional cooking

Improved cookstoves (either solar-powered or clean fuel-burning) can cut emissions by as much as 95% as well as saving lives: for example, it is estimated that 150 million clean cookstoves could help avoid 2.2 million early deaths in India.

There are even more benefits! Improved cookstoves use less fuel, which reduces the time people spend gathering firewood. This is a difficult, and sometimes dangerous, task.

Poluição em ambientes externos

Impedir a poluição em ambiente internos é apenas parte da história. O transporte é uma das principais fontes de poluição em ambientes externos e contribuiu em 16% para as emissões globais de gases de efeito estufa em 2014. Estima-se ainda que as emissões por transporte tenham contribuído para 385 000 mortes precoces em 2015.

More use of public transport and electric cars are possible solutions.

More walking and cycling would be even better – these reduce emissions, improve local air quality and help prevent diseases related to inactive lifestyles.

Protecting Nature and Health

Cutting down trees not only results in carbon emissions, but can also lead to more disease outbreaks. How?

75% of new infectious diseases in humans come from animals.

Zoonoses are diseases that come from animals

When forests are cut down, and roads built within them, humans come into much closer contact with the animals that live there. This means that diseases are more likely to spread between them.

Deforestation can cause more disease outbreaks

Impedir a perda de florestas poderia reduzir as probabilidades de futuros surtos de doenças, ao mesmo tempo em que limitaria as emissões de carbono.

And that’s not the only health reason for protecting nature. A growing body of evidence suggests that experiencing nature can have great benefits for our physical and mental wellbeing. Put simply, being around plants and animals makes us happy!

Dieta e Saúde

We currently produce enough food to feed our global population, but this is not shared equally. 11% of the global population is undernourished which means they don’t have enough food to support a normal, healthy life. At the same time, 8% of global deaths were due to obesity in 2017.

O que causa a obesidade?


Eating too much meat (particularly red and processed meats), processed food, and sugary drinks is leading to obesity as well as type 2 diabetes and some cancers.

Research suggests that healthier diets should include less processed food and meat.

Healthy diets save lives

Conclusão

Healthier diets, clean cookstoves and transport choices are just three of the ways we can improve global health and slow climate change at the same time. Solutions that help people and the planet!
