I would like to tell you about the main ecological problems in our life.They are: littering, air pollution, water pollution, endangered species, destruction of natural resources and others.
People cut down forests, pollute air and water. They don't think about their future and about future of our planet. There are many endangered species in the world. We just destroy our nature. It is very bad and we mustn't do it. We must care of our beautiful nature. We must begin from our houses, streets and towns and do them clean. People must not cut down forests, pollute air and water. They must stop killing endangered animals. We must save our planet!
Я хотел бы рассказать вам об основных экологических проблемах в нашей жизни. Ими являются: захламление, загрязнение воздуха, загрязнение воды, уничтожение животных, находящихся под угрозой исчезновения, уничтожения природных ресурсов и другие.
Люди вырубают леса, загрязняют воздух и воду. Они не думают о своем будущем и о будущем нашей планеты. В мире много вымирающих видов животных. Мы просто уничтожаем нашу природу. Это очень плохо, и мы не должны этого делать. Мы должны заботиться о нашей прекрасной природе. Мы должны начать с наших домов, улиц и городов и сделать их чистыми. Люди не должны вырубать леса, загрязнять воздух и воду. Они должны прекратить убивать животных. Мы должны нашу планету!
