Good news for fish; very bad news for people
More sea and less land is fine for penguins and for fish, but it's no good at all for people and other animals that live on the land. Some of the best land for growing food is also the most low-lying. That means it will be flooded first. It also happens that some of your biggest cities, like London, New Orleans and Bangkok, will get flooded too. Loads of people will go hungry and many more will have nowhere to live. This is very worrying.

It's also very unfair! The really sad thing is that it will be poor people who suffer most. I think that's very unfair because it's the people in rich countries who have been the cause of almost all global warming but it's the poor who drown or starve.

What do you think?
Then there's disease. As the world warms, nasty diseases like malaria are starting to spread because the changing climate favours the mosquito that carries the disease. Air travel is not just a cause of global warming and aids in spreading diseases very quickly just about anywhere. Someone with an illness like TB may easily pass on the disease to others during an airplane flight of a few hours. Insects like mosquitoes which can carry disease can even 'hitch a ride' on flights from one country to another.
