It seems to me that it's the best way of wasting money that I know of. I don't think investments on the moon pay a very high dividend.

The conservation of nature, the proper care for the human environment and a general concern for the long-term future of the whole of our planet are absolutely vital if future generations are to have a chance to enjoy their existence on this earth.

It's difficult to see how it's possible to become immensely valuable by singing what are the most hideous songs.

Can you tell the difference between them?

The world population 60 years ago was just over 2 billion and it's now more than 6 billion. This huge increase - an explosion really - has probably done more harm to the environment than anything else.

In the end we must, I think, somehow conclude that they have as much right to this planet as we have.

I just wonder what it would be like to be reincarnated in an animal whose species had been so reduced in numbers than it was in danger of extinction. What would be its feelings toward the human species whose population explosion had denied it somewhere to exist. I must confess that I am tempted to ask for reincarnation as a particularly deadly virus.
