But today many people are worried about endangered species. When animals died out in the past, it was usually because of changes in the weather or other natural causes. But today so many species are being killed in such a short time that even the fittest can’t survive. As a result, nature will get worse instead of better. We may also need these species in the future. So we must try to keep the endangered ones alive. If not, we are in fact becoming endangered ourselves.5) Discussion Besides killing, what has caused animals to die out 6) Imagine:If there were no animals and plants around us now, how would you feel about it We would feel shocked, sorry and lonely…7) QuestionsAsk and answer the following Questions:(1) Could human beings survive without all the plants and animals around us (2) What has happened to the living things on the earth so far (3) Why do animals become endangered Animals become endangered for many reasons:A) Many animals have been killed/ hunted for food or other uses.B) Many of the habitats have been changed or destroyed. C) Many rivers and lakes have been polluted. Thus, the dirty water have been a cause of animals’ death.(4) What should we do in order to have a bright future First of all, we need to …Second, we need to … Third, we can …Fourth, we shouldn’t …Integrating Skills1.
