A large part of our planet is composed of water. This is where aquatic creatures thrive, in turn providing us with sustenance. The problem is that water pollution is killing fishes and plant life. This cannot be allowed to worsen as our fishermen will no longer have much to catch for feeding our populations. Polluted rivers and beaches also threaten both the lives and the livelihood of people who are living in the coastal areas. For instance, tourist destinations can lose their appeal such that establishments will have fewer guests.
