Interesting topic. Just the other day I saw on the news that thousands of fish, literally tons, had turned up dead in a Los Angeles bay, the same had happened all over America. Also there were reports of birds falling from the sky over Arkansas recently. Not sure of the exact details, but you can google it.
In Zephaniah 1:3 it speaks about the coming 'Day of the Lord':
"I will sweep away both men and animals; I will sweep away the birds of the air and the fish of the sea. The wicked will have only heaps of rubble when I cut off man from the face of the earth," declares the LORD.
Pretty freaky stuff.
