Global Warning

    Global warning could melt the ice at the poles. This would raise the level of the oceans. Water would the cover all the flat coastal lands. People would have less land on which to live and grow food.
    Plants and animals are adapted to their climates. If the climates changes rapidly many may not be able to adapt. Some species will simply die out. Others may spread to cooler climates. There, however, they will be struggling with species already in place.
    Burning less wood, coal, oil, and natural gas will help stop global warming. Scientists recommend that people get more energy from sunlight, wind, tides, nuclear energy, and other sources that don't burn fuel. Energy sources like these put little or no greenhouse gases into the air.
    Scientists say trees can help prevent global warning. All growing plants take carbon dioxide out of the air. Trees do this especially well. They turn the carbon part of carbon dioxide into wood. They release the oxygen. In recent years, people have been cutting down forests all over the world. Scientists say vast new forest must be planted.

What is your conclusion about global warming based on the text?

Teks di atas berisi tentang fenomena alam global warming (pemanasan global). Fenomena ini merupakan fenomena di mana suhu bumi menjadi tinggi sehingga dapat mencairkan es di kutub dan dapat menutup seluruh atau sebagian permukaan bumi. Akibat dari fenomena ini adalah banyak di antara tumbuhan dan hewan yang akan kesulitan untuk beradaptasi sehingga mungkin beberapa spesies akan punah. 

Beberapa cara mengurangi dampak dari pemanasan global adalah mengurangi pembakaran kayu, batu bara, minyak dan gas dan lebih mengutamakan penggunakan energi dari matahari, angin, pasang surut, energi nuklir dan sumber lain yang tidak memerlukan pembakaran.

Para ilmuwan merekomendasikan bahwa pohon dapat mencegah pemanasarn global karena pohon dapat menyerap karbon dioksida dan mengeluarkan oksigen, tetapi saat ini manusia telah banyak menebangi pohon-pohon. Oleh karena itu, penanam pohon kembali harus dilakukan. 

Jadi, kesimpulan dari teks di atas adalah "Global warming has really dangerous effects for living things on earth and we should start increasing the use of energy that doesn't need to be burned. In addition, we can also prevent global warming by planting more trees".
