5 ways nature supports human health


Editor’s observe: This week on the UN local weather summit (COP26), Conservation International launched “Hear me while you can” — a brand new marketing campaign which invitations you to discover the soundscapes of ecosystems all over the world, from Africa’s savannas to the Amazon rainforest. 

As world leaders step up efforts to preserve important habitats, Conservation News is highlighting how nature nurtures us — and why we should shield it. Here are just a few of the ways nature supports human health. 

1. Nature fulfills our most elementary wants 

The air we breathe, the water we drink, the meals we eat — all of it comes from nature. 

According to current analysis led by Conservation International, greater than two-thirds of the inhabitants of the tropics — about 2.7 billion individuals — immediately depend upon nature for not less than one in every of their most elementary wants.

The research’s maps establish precisely the place individuals depend upon pure sources essentially the most — and underscores the threats that local weather change and the destruction of nature pose to human life.

“Depending on where you are in the tropics, threats include logging, unsustainable farming practices and mining — all of which can reduce access to food and clean water, building materials and endanger livelihoods,” mentioned Giacomo Fedele, a Conservation International scientist and lead creator on the paper. 

The excellent news: These maps also can assist information conservation by focusing efforts on the locations most crucial to human well-being.  

“Knowing where nature-dependent people live can help governments and decision-makers implement effective conservation and sustainable development strategies based on what resources these communities rely on the most,” mentioned Fedele.

2. Nature may also help stop future pandemics

Environmental degradation, deforestation and wildlife trafficking drive illness outbreaks: Seventy % of rising viral illnesses have unfold from animals to people. 

As people encroach deeper into tropical forests, they’re more and more uncovered to wild animals — and the illnesses they could carry, similar to Ebola and COVID-19. 

A current research co-authored by Conservation International specialists outlined a groundbreaking plan to lower the chance of future pandemics by 27 % or extra — with a 10-year funding that’s 50 instances lower than the price of coronavirus response efforts so far. How? By defending nature. 

The technique is three-pronged: scale back deforestation, limit the worldwide wildlife commerce and monitor the emergence of latest viruses earlier than they unfold. Making certain that forests stay intact limits the possibilities that people are uncovered to zoonotic illnesses, defined Lee Hannah, a Conservation International scientist and co-author on the research. 

“To help prevent the next pandemic, it is crucial for countries and businesses to incentivize protecting forests rather than destroying them,” he instructed Conservation News. 

“Not only is this good for public health, it will help slow climate change.” 

3. Nature is the world’s “medicine cabinet”

Conserving nature may also help stop infectious illness outbreaks. But do you know nature also can deal with diseases? Many modern-day medicines — together with aspirin, penicillin, morphine and several other chemotherapeutics — have been derived from vegetation and fungi.

In some circumstances, marine life has impressed designs of medical know-how, similar to synthetic shark pores and skin that forestalls bacterial progress when utilized to hospital surfaces.

However, widespread biodiversity loss and deforestation may threaten reserves of medication within the wild — together with treatments which have but to be found. 

“People have only harnessed the properties of a relatively small number of species,” Melanie-Jayne Howes, a organic chemistry researcher, instructed The Guardian. “Some of the chemicals that plants and fungi produce are so complex we still can’t produce them synthetically – take vincristine, used in the treatment of children’s leukemia, and vinblastine, used to treat Hodgkin’s disease.”
