  • Global warming has become perhaps the most complicated issue facing world nowadays.

  • APA YANG DIMAKSUD DENGAN PEMANASAN GLOBAL? Ternyata Planet menjadi memanas dengan cepat dan sulit dikendalikan

  • Kenaikan temperatur bumi, ini terjadi karrena gas rumah hijau/KACA (carbon dioxide, penguapan air, nitrous oxide dan methane) menerangkap dan menghalangi panas dan sinar dr matahari keluar dr atmospher bumi.. Hal ini berakibat pada peningkatan suhu bumi, sehingga berakibat pada sakit dan cideranya manusia hewan dan tumbuhan.

  • Apa yang dimaksud dg efek rumah kaca/the greenhouse effect?The greenhouse effect is when the temperature rises, because the suns heat and light is trapped (terperangkap) in the earths atmosphere.The heat and light can get through the atmosphere, but it cant get out. As a result, the temperature rises. But, sometimes the temperature can change in a way that helps us.

  • The greenhouse effect makes the earth appropriate for people to live on.

  • Without it, the earth would be freezing=>, It would be freezing at night because the sun would be down. We would not get the suns heat and light to make the night somewhat warm.

  • On the other hand it would be burning hot .=> During the day, especially during the summer, it would be burning because the sun would be up with no atmosphere to filter it, so people, plants, and animals would be exposed to all the light and heat.

  • What is global warming doing to the environment?Makes the sea rise : the water covers many low land islands, the plants and causes some of them to die so, the animals lose a source of food, along with their habitat,but people lose two sources of food, plant food and animal food

  • Global warming, is harming and killing algae in the ocean.=> Fewer algae is a problem because there is less food for us and many animals in the sea.

  • One thing that causes global warming is electrical pollution, fossil fuels are burned to create electricity. Fossil fuels are made of dead plants and animals. Many pollutants are sent into the air when fossil fuels are burned. Some of these chemicals are called greenhouse gasses.

    The pollution that causes global warming is linked to acid rain.=> Acid rain gradually destroys almost everything it touches

  • Disamping itu, pemanasan global diperparah dengan penebangan hutan yg tidak terkendali. Padahal pepohonan dan tumbuhan lain di hutan merup pengumpul gas carbon dioxide (CO2), yg mana merup salah satu greenhouse gas (deforestration)

    Global warming=> it is also destroying many huge forests, (mudah terjadi kebakaran hutan) This happens because global warming can make the earth very hot.

  • Dalam kehidupan kita membutuhkan O2 yang diproduksi oleh tumbuh-tumbuhan sebgai contoh alga di kehidupan lautan.Sedangkan tumbuhan memerlukan CO2 untuk fotosintesis kehidupannya...Bagaimana akibatnya bila banyak terjadi penebangan dan pemusnahan tumbuhan?CO2 beterbaran di udara, dan inilah yg akan memperparah pemanasan global. CO2 merupakan salah satu gas rumah kaca

  • APA YG HARUS KITA LAKUKAN UNTUK MENGHENTIKAN PEMANASAN GLOBAL?
