Sustainable Development

- [Narratore] Lo sviluppo
sostenibile è la pratica

di soddisfare le esigenze
umane attuali garantendo

anche che le generazioni future avranno

le risorse di cui hanno bisogno.

Tre principali aree di sviluppo,

sociale, economico ed ecologico,

sono intrecciati all'interno
di questo concetto.

Dal punto di vista biologico,

lo sviluppo sostenibile richiede ricerca

per capire le questioni ecologiche

e attuare gli sforzi di conservazione

per preservare la biodiversità
e le risorse naturali.

Studiare come interagiscono gli organismi

tra loro e con il loro ambiente,

e come gli ecosistemi sono
influenzati dalle attività umane,

può guidare gli sforzi per
mantenere o migliorare gli

standard

di vita per l'uomo proteggendo
allo stesso tempo la fauna

selvatica e preservare la biodiversità.

I requisiti energetici delle
nazioni industriali sono una

sfida ambientale importante
nello sviluppo sostenibile.

Si fa ancora affidamento
ui combustibili fossili

per l'energia ma sono
una risorsa limitata.

Inoltre, bruciando questi
combustibili si libera anidride

carbonica nell'atmosfera,
portando a cambiamenti climatici.

Sostituire i combustibili
fossili con fonti di energia

rinnovabile, come
l'energia eolica e solare,

fornisce un esempio di
sviluppo sostenibile in atto.

Anche la terra e l'acqua
sono risorse limitate

quindi lo sviluppo sostenibile
in agricoltura è essenziale

per produrre abbastanza cibo
per le persone ora e in futuro.

La rotazione delle colture
nei campi è un esempio

di una pratica agricola sostenibile.

La rotazione agricola minimizza
la perdita di nutrienti nel

terreno nel tempo

consentendo una crescita più
efficiente delle colture e

riducendo l'impatto dei
parassiti che infestano colture

specifiche,

come il mais, in diverse
stagioni di crescita.

sviluppo sostenibile

Mentre la popolazione umana continua a crescere e a utilizzare le risorse, dobbiamo essere consapevoli dei limiti naturali del nostro pianeta. Lo sviluppo sostenibile rappresenta un percorso per mantenere e migliorare la vita umana, garantendo al contempo che le generazioni future dispongano delle risorse di cui hanno bisogno. Il successo a lungo termine degli sforzi di sostenibilità si basa sulla comprensione dell'interazione tra azioni umane e sistemi ecologici.

Gli oceani sono un importante punto focale degli sforzi di conservazione a livello mondiale. La pesca eccessiva, l'inquinamento e gli effetti dei cambiamenti climatici, come l'acidificazione degli oceani e l'innalzamento del livello del mare, sono solo alcune delle principali preoccupazioni che devono essere affrontate per proteggere gli oceani del mondo. Oltre a fornire grandi quantità di cibo per gli esseri umani, gli oceani sono un'importante fonte di ossigeno atmosferico e forniscono un bacino di carbonio per il gas di CO2. Aiutano anche a regolare il clima e influenzano i modelli meteorologici in tutto il mondo.

Uno dei principali obiettivi dello sviluppo sostenibile è la pesca oceanica. I moderni metodi di pesca consentono la raccolta di un gran numero di pesci in una sola volta, che è efficiente a breve termine, ma provoca anche l'esaurimento locale delle popolazioni ittiche, che può avere effetti attraverso la rete alimentare oceanica. Gli attuali metodi di pesca su larga scala provocano anche la morte di altri animali, come i delfini e gli uccelli marini, che vengono catturati nelle reti insieme ai pesci bersaglio previsti. Di conseguenza, le organizzazioni di conservazione stanno lavorando con l'industria della pesca per progettare nuovi attrezzi da pesca che prevengono le catture indesiderate. Inoltre, sono state emanate norme per prevenire l'esaurimento delle popolazioni ittiche di valore commerciale. A lungo termine, tali sforzi sono utili anche per le persone, che possono continuare a fare affidamento sul pesce come fonte di cibo solo se non sono spinti all'estinzione.

Lo sviluppo sostenibile ha lo scopo di migliorare la vita degli esseri umani, ma affinché abbia successo, deve comportare anche un'attenta gestione degli ecosistemi e degli altri organismi che condividono il pianeta con noi.

protecting oceans for sustainable development

Sustainable development depends on protecting oceans while meeting human needs. As the human population grows and uses more resources, people must stay aware of the planet’s natural limits. The goal is to improve life now without taking away the resources future generations will need.

Long-term sustainability depends on understanding how human actions affect ecological systems. Oceans are a major part of this balance. They provide food for people, produce much of the atmosphere’s oxygen, and act as a carbon sink, which means they absorb and store carbon dioxide. Oceans also help regulate climate and shape weather patterns around the world.

Ocean conservation faces several major problems. Overfishing can reduce local fish populations and affect the entire ocean food web. Pollution, ocean acidification, and rising sea levels are also serious concerns linked to climate change. These pressures make it harder to protect marine ecosystems and the services they provide.

Fishing is one of the main areas where sustainable development is needed. Modern fishing methods can catch many fish at once, which is efficient in the short term. But these methods can also lead to unwanted catches, including dolphins and sea birds, and can deplete commercially valuable fish populations. Conservation groups and the fishing industry are working on new gear that reduces bycatch, the accidental capture of non-target animals. Regulations also help limit overuse of fish stocks. In the long run, these efforts support both ocean life and people who depend on fish as a food source.

what is weather?

How Sunlight Shapes Daily Weather

Weather is the current state of the atmosphere at a specific time and place. It is temporary and changes from one location to another. Weather is shaped by the interaction of the sun, atmosphere, hydrosphere, and geosphere. Solar radiation reaches Earth and interacts with water and land. These surfaces release that energy as thermal radiation, or heat, which warms the air above them. Some of that heat escapes back into space, but some is trapped by atmospheric gases. This heat retention is...

global climate change

Ancient Clues to Climate Change

Ancient climate clues help scientists track global climate change. Paleoclimatology is the study of climate conditions in Earth’s past and the causes and effects behind them. By comparing recent climate patterns with older records, researchers can find strong evidence for human-caused warming. Earth’s climate has changed many times over its 4.5 billion year history. In the last 650,000 years, there have been seven cycles of glacial advance and retreat. The most recent ice age ended more than...

what is biodiversity?

Biodiversity Across Genes, Species, and Ecosystems

Biodiversity is the variety of living things at the genetic, species, and ecosystem levels. It includes not only how many kinds of organisms exist, but also how they are related and how they interact with the world around them. Species diversity spans the full evolutionary tree. It includes single-celled prokaryotes such as bacteria and archaea, as well as the eukaryotic kingdoms: plants, animals, fungi, and protists. About 1.75 million species have been identified so far, and scientists...

threats to biodiversity

How Humans Change Biodiversity

Human activity is changing biodiversity and pushing Earth toward a sixth extinction event. Earlier mass extinctions ended many species, and then new species spread into the changed environment. Today, the Holocene epoch is seeing a mass extinction linked to human actions, and it is often called the Anthropocene. Human numbers and human biomass show how large this impact has become. In 2019, the human population reached 7.7 billion and is projected to rise to 10 billion by 2060. By biomass,...

conservation of declining populations

Saving Species Through Population Recovery

Conservation of declining populations focuses on detecting a population drop, finding its cause, and stopping further loss. The goal is to prevent extinction by using scientific methods to identify the agents behind the decline. Once the cause is known, conservation teams can remove, oppose, or neutralize it. A common step is to test possible causes with a small trial group. If the cause is confirmed, the remaining animals may be moved to an unaffected area. When the population is too small or...

biodiversity and human values

Biodiversity in Food, Tools, and Medicine

Biodiversity supports human life through food, tools, medicine, and many other needs. Changes in the variety of species can also change the environment. Those environmental shifts can alter weather patterns and affect human civilizations. People have depended on biodiversity for agriculture since early human history. Agriculture began when ancestral humans found species that were good sources of food. At least 11,000 years ago, people started selecting plant and animal species to raise on...

what is conservation biology?

Protecting Biodiversity in Conservation Biology

Conservation biology is the science of protecting biodiversity and keeping ecosystems healthy. It looks at how living things, habitats, and human needs are connected. The goal is to preserve biodiversity so ecosystems can continue to function well. Healthy ecosystems provide people with important natural resources. These include food, medicines, and building materials. Ecosystems also deliver key services, such as cleaning air and water. Evidence shows that these services depend on...

what is climate?

Climate Patterns and Earth’s Energy Balance

Climate describes the usual weather conditions in a place over a long period of time. The idea is simple: climate is what you expect, while weather is what you get. Climate is shaped by geographic factors such as latitude, terrain, and how close an area is to bodies of water. Weather and climate are related, but they work on different time scales. Weather is the state of the atmosphere at a specific time and place. Climate is the average pattern of weather over much longer periods. Because of...

conservation of small populations

Saving Small Populations with Genetic Diversity

Small populations can be hard to save because they often lose genetic diversity. When variation is low, a species has fewer traits that may help it adapt to climate change, competition from other species, or new diseases. That makes extinction more likely. Large populations usually have a better chance of surviving new stresses. They are more likely to include individuals with genetic variants that are helpful in changing conditions. Small populations are much less likely to contain this kind...

habitat fragmentation

How Fragmented Habitats Affect Wildlife

Habitat fragmentation breaks one continuous habitat into smaller, separate patches. Human land conversion is a major cause of this change, and slower geological shifts in the physical environment can also fragment habitats. The process usually follows the same stages: perforation, dissection, fragmentation, shrinkage, and attrition. Perforation and dissection often begin during land development. Perforation happens when undeveloped land is cleared for something like a home, and dissection...
