Nowadays, global warming is becoming a concern to people all over the world.
As is know to all, global warming results from two main reasons. On the one hand, factories produce large amounts of green house gases. On the other hand, entensive deforestation contributes to the rise of temperature.
Admittedly, global warming will cause terrible effects. First of all, with the temperature going up, some animals and plants will die out. Additionally, crops will produce less. Worse still, it will bring about the rise of the sea level.
Faced with this threat, we should take measures to solve it. I consider it advisable to cut down the sending out of the greenhouse gases. Moreover, more importance should be attached to planting trees.
