The impacts of climate change and air pollution are particularly difficult to identify with a high degree of confidence. One of the main reasons for this is that climate and air pollution are rarely measured at sites where biodiversity is monitored so potential relationships can only be assessed by using interpolated national data. These interpolated values can be reliable in some circumstances (for example nitrogen dioxide deposition or temperature in flat terrain) but can be very unreliable in others (for example ammonia deposition or precipitation in sites with varied topography). The effect of uncritically. | What Is This Module About Water is one of the most important and most widely used substances on earth. Seventy percent 70 of the earth s surface is covered with water abundant enough to supply the needs of men animals and plants alike. Yet despite such an abundance we still experience water shortage.

Safety tips will likewise be taught to you so that you can readily protect your health from toxic chemicals accidentally spilled in various bodies of water. This module will also discuss the problem of water shortage. To help solve this problem you have to learn how to conserve and protect water resources. The module is divided into two lessons Lesson 1 Why Is Water Pollution Harmful Lesson 2 What Can You Do to Help Fight Water Pollution What Will You Learn From This Module After studying this module you should be able to describe problems related to water pollution identify the causes and harmful effects of water pollution on our health environment domestic life and economy discuss the government s efforts in solving the problem of water pollution and prepare a
