Hi, I'm Patricia Ruiz and I'm writing this today to explain a little bit about this big problem affecting the whole world: global warming and its undesirable effects. I'm also giving my suggestions as to what we could all do to stop it.

What is the global warming? The global warming is an increasement of the temparature in the Earth's. The atmosphere need the CO2 to keep the temperature confortable for the life. But, we are changing this. The energy that we use come from the burn of the fossils fuels. This produce a lot of CO2 so, this is bad. With this contamination the temperature will increase and if only increase 4ºC, many of cities are going to disappear, fo example Manhattan. Also, there will be a lot of floodings and it will not rain. The crops are going to disappear and the majority of the places will be a desert.

We are producing the climate change and if we don't want to destroyed the planet, we have to do something. All know the theory about that perfectly, but why we don't do anything? We can do small actions to save energy and is effortless. Here I´m going to put a small list with the small actions that we can do:

· Recycle paper, plastic and glass.

· Reuse the things that they are not destroyed. · Turn off the heater and put an pullover. · Turn off the lights if they are not necesary. · Don´t leave the tv in stand-by. · Don´t use the water like a bing. · Use energy saving lightbulbs. · Close the tap when you are cleaning your teeth, for example. · Use public transport, a bike or walk.

Here I put some of the things that we can do, but there are a lot. You can find on internet many more and you can choose what you can promise that you are going to do.

The world need your help and you have to do something.
