One of the most concern issues which is considerable danger to our environment is the pollution of rivers, lakes and seas. There are many causes relating to the water pollution and in this essay I will elaborate the causes and mention several consequences that human and animal have to deal with because of these problems.

The most common cause of water pollution is the direct disposal of industrial waste from the factories. Many companies have polluted the water when they are dumped waste to the water without any management. For instance, nowadays many developing countries have the high rate of polluted water and lack of fresh water resources to use when the age of industrialization is coming. Moreover, as the result of over-used of pesticides in agriculture, the toxic chemical is being discharge to the water and the soil which may have a fundamental effect on the environment.

The impact on animals would be severe while human have to face up with challenging situation since there is a rapidly increase in the waste have been dumped to the seas. First of all, it is significant that endangered animals may lost their habitants and food supply when the water is polluted. For instance, many fishes and marine creatures is killed by the interventions of human. Therefore, the effects on human health would result in the high rate of respiratory diseases these days.

In conclusion, we may argue that emissions and dumping are two main reason for the threats of pollution water that people have to handle immediately. It dramatically affects both the life of animals and human being.
