If you are going to introduce one environmental problem, what problem will you choose Why
I will choose water pollution. Clean water, reliable toilets and good hygiene are what keep us all healthy. They should be a normal part of daily life for everyone, everywhere—but they aren't. We're in a position to change that. I think we should try our best to protect water.

Let's take water pollution as an example.
There are various causes of water pollution. Large amounts of industrial waste poison the water after they enter water bodies. Moreover, animal and human waste pollutes the water. Water pollution is also caused by poisonous chemicals used in agriculture.
Causes of water pollution
Polluted water bodies not only do harm to animals and plants; they also have a long-lasting effect on humans. For example, in many parts of the world, the poor quality of the local drinking water gives rise to public health problems.
Consequences of water pollution
To prevent further damage to water bodies, it is necessary to take some measures. First, we must draw public attention to the problem. Second, more strict laws should be passed to help reduce water pollution. Third, we can volunteer to take part in clean-up activities.
