The Truth about Global Warming

More and more teenagers are worried about the environment. Teen World takes a look at the biggest environmental problem facing our world.

Teens everywhere are re becoming more in more interested in ponment. The main issue today is global warming. It’s caused by the increase of greenhouse gases, which keep the heat from the sun in the air. Sulfur dioxide (SO2) is one of the most common greenhouse gases. It’s mostly caused by burning fossil fuels. We consume fossil fuels for our transportation and the energy in our homes. Deforestation is another human activity that only makes global warming worse. Trees remove greenhouse gases from the air, so we need to protect the forests.

What can we do? First of all, in order to reduce greenhouse gases, we should shut down coal and of power plants. We should switch to more sustainable kinds of energy, such as wind and solar power, even if they cost more. Instead of gas, we could switch to using biofuels, which are made from plants and other living things. Secondly, we should prohibit cars and motorbikes from downtown areas and increase the tax on gas to make it more expensive to use them. Using more electric vehicles, especially electric buses, is another good idea.

Protecting our forests and planting more trees are both very important. It’s hard to stop farmers from cutting down trees, so governments have to make strong laws to protect forests.

There are many things we can do at home to help. We can all help save energy at home by turning off the lights and also switching to energy-saving devices.

These are the solutions we can use to stop global warming. We can still save our planet if people act now.
