Man has had many far-reaching effects on the environment over the years. Global warming, pollution and the damage to the ozone layer are a few of the major things that can be heard about in the news. Man has damaged the earth gradually over the years and this damage cannot be reversed, we are now trying to stop any more damage being caused to the environment. For example, hedgerows have been destroyed but now people have realised what effects this is having on the environment the government are paying farmers to replant them instead of fencing. Not all of man's effects on the environment are harmful some are beneficial. Conservation work is going on across the country and this is helping to preserve the wildlife and countryside that we have left. The expanding human population has placed a huge demand on the food production of the country. The resources are limited but the population is increasing quite rapidly so the problems are growing. The demand for food means that crops need to be perfect so the use of fertilisers and herbicides is increasing too.
One of the problems in the countryside affecting the environment is the disposal of effluent and other pollutants. The main type of waste that we have to dispose of is organic effluent particularly from farms and sewage works. This is disposed of in several ways, the main one being pumping it into the sea and rivers around the country. In more recent years sewage recycling plants have been developed to reuse the water in the waste. Water treatment works are used to treat the waste before it is pumped into the river or sea.
