Por favor ayúdenme a contestar estas pregunta cada una de 80 palabras por lo menos ¿Crees estar inserto en un mundo globalizado?
diamong [38]

Answer:

1- Efectivamente, hoy en día nos encontramos viviendo en un mundo globalizado, ya que se trata de un sistema mundial interconectado, donde todas las sociedades y gobiernos tienen una comunicación fluida y constante entre sí en forma rápida y dinámica. Esto se ha logrado a través del desarrollo de los medios de comunicación, que permiten la conectividad a gran escala.

2- Un aspecto positivo de la globalización en mi vida personal es que el desarrollo de las comunicaciones y las tecnologías me permite poder comunicarme con personas de mi familia que viven en otro país a decenas de miles de kilómetros de distancia, con solo apretar un botón y esperar tan sólo unos pocos segundos. Es decir, la globalización acorta las distancias y reduce los tiempos, uniendo más a las personas y, por ende, a los pueblos y países.

3- Un efecto negativo de la globalización es que todos los eventos políticos y sociales que ocurren en un país tienen repercusión en los demás países. Por ejemplo, una ley en los Estados Unidos puede influir en el desarrollo del comercio en Latinoamérica, influyendo negativamente en las economías de países con menor desarrollo, pudiendo causar problemas económicos a estos.

Human beings are major cause in increasing pollution by various means whether its chemical industrial metallic or any other type of pollution. The major contributing factor in aiding pollution is the smoke from factories or vehicles which increases the carbon dioxide level above normal and when these gases rises they are trapped inside the earth surface and produce a green house effect. This is the main reason that scientists think aboutglobal warming.
