2. Read the passage
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 fish, 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?

Causes and effects of noise pollution in Hanoi If you are now living in a big city like Hanoi, you will want to enjoy peaceful moments in the silent countryside to escape the noisy life of the busy city. Very few people seem to notice that we have to hear unwanted sounds from when we take our motorbike out of the house in the morning until bedtime. The undeniable fact is that Hanoi is the second most polluted city in Vietnam, so traffic jams often happen during rush hour. The noise from vehicles is probably the main reason for noise pollution in Hanoi. Since the development of technology, offices are all equipped with devices such as computers, air-conditioners, and printers which cause annoying sounds. Noise pollution can not only happen in workplace but also at homes. Household devices including fridges, air-conditioners, and TVs produce sounds that make our ears overload. We will never take these noises into consideration until we see the effects of it in our own life or to people around us. The sounds are not harmful to our health immediately, but being exposed to them for a long time can cause problems. Having to listen to the noise can bring negative impacts to our hearing ability. Moreover, it can increase our stress and anger when being exposed to it. This then affects our mental and psychological health. All of us want to have healthy ears, a stable mind, and a happy life. Therefore, we need to be well-equipped with knowledge about noise pollution and protect ourselves from it. We should wear protective devices for our ears and turn off technology products when unnecessary.
