Question

select all the correct answers.

the graph shows that since the early twentieth century, the concentration of \\(\text{co}_2\\) in the air has increased to historic levels. based on this timeline, which three of the following developments could explain this rapid deviation from expected temperatures?

industrial activity had increased, which involved burning fuels like coal.
people began eating less chicken and seafood and more pork and beef.
the global human population is continuously increasing, straining resources.
harnessing solar and wind energy became more affordable and widespread.
there was an increasing number of fossil-fuel burning vehicles on the roads.

Explanation:

Analizar la relación entre las actividades humanas y el aumento de CO₂

El gráfico muestra un aumento exponencial y sin precedentes en los niveles de dióxido de carbono atmosférico (\(\text{CO}_2\)) desde la Revolución Industrial (alrededor de la línea de 1950 y el nivel actual). Este rápido aumento se correlaciona directamente con el crecimiento de la población humana y la quema masiva de combustibles fósiles.

Evaluar las opciones presentadas

1. Industrial activity had increased, which involved burning fuels like coal: Correcto. La industrialización basada en el carbón y otros combustibles fósiles es la causa principal de las emisiones masivas de \(\text{CO}_2\).
2. People began eating less chicken and seafood and more pork and beef: Incorrecto. Aunque la ganadería vacuna genera gases de efecto invernadero (principalmente metano, \(\text{CH}_4\)), este cambio dietético específico no explica la desviación masiva y directa del \(\text{CO}_2\) atmosférico mostrada en la escala temporal del gráfico.
3. The global human population is continuously increasing, straining resources: Correcto. El crecimiento demográfico exponencial multiplica la demanda de energía, transporte y recursos, acelerando las emisiones globales.
4. Harnessing solar and wind energy became more affordable and widespread: Incorrecto. El uso de energías renovables reduce las emisiones de \(\text{CO}_2\), por lo que no explicaría un incremento tan rápido y drástico.
5. There was an increasing number of fossil-fuel burning vehicles on the roads: Correcto. El auge del transporte motorizado basado en derivados del petróleo es uno de los mayores contribuyentes al aumento de \(\text{CO}_2\) desde el siglo XX.
