I first heard about the ozone layer about twenty years ago. I was still in school. I thought it was interesting, but I didnt take it seriously. It was a bit like science fiction, I mean, how could there be a giant hole in the atmosphere? Over the yea...
Overpopulation is a real problem. It could kill the Earth. Very soon, there will be too many people and not enough land. There wont be enough farms to grow food for everyone. Well eat all of the fish in the sea. And our pollution will cause more glob...
The question of organ transplants is a difficult one. Not for me though. Im quite happy to donate all of my organs for transplants. I dont mind my body being donated to science after I die. I think its much better to be useful even after I die. I wou...

I like the expression OK. I dont know why. Its so useful. Everyone in the world understands what it means. It must be the only word that everyone knows. Is it a word or is at an abbreviation? We spell it okay but abbreviate it as OK. I wonder how man...
Oil is good and bad. Its good because it helps our energy needs. Its bad because it causes pollution. Oil is a fossil fuel. Burning it produces carbon dioxide (CO2). This is one of the biggest causes of global warming. There isnt much oil left in the...
I really worry about our oceans. Not many people understand how important the oceans are. Every day we hear stories about the rainforests and the ice caps, but we rarely hear about the oceans. They form most of the Earths surface and most of the worl...
