Answer and Explanation:
Easter Island, a small island of around 64 square miles, has been a mystery for many scientists who study the changes on the past and current biodiversity abundance. According to research, this island used to be extremely diverse in species of fauna and flora, especially the latter. However, it is now composed of few species of invertebrates and little to almost no vegetation. This occured <u>due to the first colonizers</u> who rapidly deforested the region.
Research suggests that, apart from this deforestation, which caused the decline of wildlife species that depended on shrubs and palm trees, Polynesian colonisers introduced the Polynesian rat, which consumed almost all of the trees that were present in the island, leading to the absence of their regeneration.

Antifreeze is also known as an "engine coolant."<u> </u><u>This is a toxic chemical that should not be ingested.</u> The frogs from the pond behind his house must have ingested the engine coolant, thus resulting to their deaths. It is said that animals are attracted to its smell, thus they are more prone to ingesting or drinking it.
If you are doing it on your own without going to the service station, it is best to bring the substance to the appropriate facility that disposes it. However, in case you spill it accidentally, you may pour some soap and water so it can be mixed together, thereby reducing its toxicity.
