Activity 1: Guess True or False for each sentence below.
1. Groundwater is the water above the Earth`s surface.
2. Industrial waste, sewage, pesticides and herbicides are factors cause `point source pollution.
3. The outbreaks of cholera, the death of aquatic animals and plants are the effects of water pollution.
4. Polluted water only makes aquatic animals die.
Water pollution is the contamination of bodies of water such as lakes, rivers, oceans and groundwater (the water beneath the Earth’s surface). It is one of the most serious types of pollution.
Water pollution can have many different causes. Factories dump industrial waste into lakes and rivers. Sewage from households is another cause. Farms using pesticides to kill insects and herbicides to kill weeds can also lead to water pollution. These factors cause ‘point source’ pollution while pollutants from storm water and the atmosphere result in ‘non-point source’ pollution.
Water pollution can have dramatic effects. In many poor nations, there are frequent outbreaks of cholera and other diseases because of people drinking untreated water. Humans can even die if they drink contaminated water. Polluted water also causes the death of aquatic animals such as fishes, crabs, or birds. Other animals eat these dead animals and may also get sick. In addition, herbicides in water can kill aquatic plants and cause further damage to the environment.
So what should we do to reduce water pollution?
