Many people underestimate the power of nature. When she twitches a muscle she can take out much of man's doings.
The Waimakariri where we live was in flood last week. Carving a straight mouth to a couple of hundred meters wide. Cutting two meter banks in the old beach. An enormous amount of sand removed in a few hours. But within the next tide cycle it had replaced almost all that sand. Millions of tonnes in a few hours. The sea and the wind do similar work. There are people who would stop vehicles on this beach, claiming damage to the environment. The hundreds of fishermen and families who enjoy our beach have all traces removed in one tide cycle and one strong wind. Lets concentrate on the things that do matter. Poisoning the environment and taking too much.
