Sustainable Development

- [Narrador] El desarrollo
sostenible es la práctica

de satisfacer las necesidades
actuales garantizando

que las futuras
generaciones también tendrán

los recursos que necesiten.

Hay tres áreas principales de desarrollo,

social, económica y ecológica,

y están entrelazadas
dentro de este concepto.

Desde una perspectiva biológica,

el desarrollo sostenible
requiere investigación

para entender los problemas ecológicos

e implementar esfuerzos de conservación

para preservar la biodiversidad
y los recursos naturales.

Estudiar cómo interactúan los organismos

uno con el otro y su entorno,

y cómo los ecosistemas

se ven afectados por
las actividades humanas,

puede impulsar esfuerzos
para mejorar los estándares

de vida para los humanos

y también proteger la vida silvestre

y proteger la biodiversidad.

Los requerimientos energéticos

de las naciones industriales
son un importante

desafío ambiental en el
desarrollo sostenible.

Aún dependemos en gran medida
de combustibles fósiles

pero estos son un recurso finito.

La quema de estos combustibles
libera dióxido de carbono

a la atmósfera, impulsando
el cambio climático.

Sustituir estos combustibles
por energías renovables,

como la energía eólica y solar,

proporciona un ejemplo de
desarrollo sostenible en acción.

La tierra y el agua también
son recursos finitos

por lo que el desarrollo sostenible

en la agricultura es esencial

para producir suficiente
comida ahora y en el futuro.

La rotación de cultivos en
los campos es un ejemplo

de una práctica agrícola sostenible.

La rotación de cultivos minimiza

la pérdida de nutrientes
en el suelo con el tiempo

lo que permite un crecimiento
de cultivos más eficiente

y reduce el impacto de las plagas

que infestan cultivos específicos,

como el maíz, en múltiples
etapas de crecimiento.

desarrollo sostenible

A medida que la población humana continúa creciendo y utilizando recursos, debemos ser conscientes de los límites naturales de nuestro planeta. El desarrollo sostenible proporciona un camino para mantener y mejorar la vida humana ahora y al mismo tiempo garantizar que las generaciones futuras tengan los recursos que necesitan. El éxito a largo plazo de los esfuerzos de sostenibilidad depende de la comprensión de la interacción entre las acciones humanas y los sistemas ecológicos. Los océanos son un foco importante de los esfuerzos de conservación globales. La sobrepesca, la contaminación y los efectos del cambio climático, como la acidificación de los océanos y el aumento del nivel del mar, son sólo algunas de las principales preocupaciones que deben abordarse para proteger los océanos del mundo. Además de proporcionar grandes cantidades de alimentos para los humanos, los océanos son una fuente importante de oxígeno atmosférico y proporcionan un sumidero de carbono para el gas CO2. También ayudan a regular el clima e influyen en los patrones climáticos en todo el mundo. Uno de los principales focos del desarrollo sostenible es la pesca oceánica. Los métodos de pesca modernos permiten recolectar grandes cantidades de peces a la vez, lo cual es eficiente a corto plazo pero también provoca el agotamiento local de las poblaciones de peces, lo que puede tener efectos en toda la red alimentaria del océano. Los actuales métodos de pesca a gran escala también provocan la muerte de otros animales, como delfines y aves marinas, que quedan atrapados en las redes junto con los peces objetivo. En consecuencia, las organizaciones conservacionistas están trabajando con la industria pesquera para diseñar nuevos artes de pesca que eviten capturas no deseadas. Además, se han promulgado regulaciones para evitar el agotamiento de poblaciones de peces de valor comercial. A largo plazo, estos esfuerzos también son beneficiosos para las personas, que sólo podrán seguir dependiendo del pescado como fuente de alimento si no se las lleva a la extinción. El desarrollo sostenible tiene como objetivo mejorar la vida de los seres humanos, pero para que tenga éxito, también debe implicar una gestión cuidadosa de los ecosistemas y otros organismos que comparten el planeta con nosotros.

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...
