La respuesta correcta para esta pregunta abierta es la siguiente.
A pesar de que no se incluyen opciones o incisos para responder, podemos comentar lo siguiente.
Es cierto que cuando llegaron los Europeos a territorio Mesoamericano, las ciudades Mayas estaban en ruinas o abandonadas. Se atribuye este fenómeno a que los historiadores piensan que las ciudades Mayas ya estaban deshabitadas desde hace cientos de años antes de la llegada de los Mayas.
De hecho, de acuerdo a las investigaciones de los historiadores modernos, antropólogos, y arqueólogos, los Mayas desaparecieron sin dejar rastro alguno. Es un verdadero misterio. Al día de hoy, no existe evidencia alguna que confirma una razón válida por la que los Mayas desaparecieron. Todas son teorías.
De ahí que las principales ciudades Mayas como Chichen Itzá, Tulum, Palenque o Bonampak, se hayan descubierto mucho tiempo después con gran dificultad ya que las ciudades quedaron atrapadas por la selva, llena de maleza y vegetación.
Sure! Do not worry this is all original no plagarism in this :)
Water pollution causes many problems to the eco system that it is affecting. As the pollution spreads it begins to affect the wildlife eventually killing them off. This affects the food chain in the area. For example if pollution began to affect the water in the Florida Everglades it would kill the fish living in the area. Then alligators would not have enough food to eat therefore their population would slowly decrease. Eventually humans would be affected as well. People can get diseases by eating seafood that has been poisoned or drinking the contaminated water. Water pollution from major events like acid rain or oil spills can completely destroy marine habitats. This leaves animals without a place to live therefore meaning they have a less chance of survival.
Hope this helps! (Please mark?)

It's asking how the westward expansion effected the native americans. A lot of it resulted in many native americans losing their homelands & being violently suppressed. They were forced out of the regions where they lived. A lot were killed from battles & diseases (diseases brought from the europeans). They wanted to keep their land that was being taken from them, hence the reason for the battles which resulted in many native americans lives being lost.
Hope that helped a bit.
