One of our biggest environmental problems is global warming. It comes from our diet, water consumption, deforestation, energy consumption and transport as well. The world will not exist in the future, if we don’t do something/change our habits.

There are a lot of cars on our roads, so we can go by public transport instead of going by car. This way, cars will pollute less and global warming will slow down.

We can also reduce meat consumption, so there will be less cattle and less gases in the atmosphere, too.

With small changes like these, we will help to reduce global warming.
