The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Before the earth day protest started the environmental movement.
industries used to treat the environment very poorly. Indeed, major industries around the world did not have any respect or consideration for taking care of nature. These industries were only interested in big profits no matter what. They produced their goods and polluted the air, polluted the water, and also contributed to noise pollution.
These industries never considered that raw materials and natural resources are limited, and one day, humans are going to suffer if we as citizens of the world do not put a stop to these large corporations.
