Những Cư Dân Tuyệt Vời Của Địa Cầu, Phần 2/2

Animals bless humans invisibly and physically. Assistance dogs selflessly aid the disabled with their keen hearing, superb sense of smell, and ability to detect danger. They also protect and guide people whose vision is impaired. When they return to the surface to breathe, the cetaceans may release waste matter containing much nitrogen and iron into the water. These elements, with the addition of sunlight, are what phytoplankton need for their development. The humble bees and other insects are indispensable for conveying pollen, thus ensuring viable fruit and vegetable crops. So you can see that on land as well as in the water and air, the animals all have a specific purpose to fulfil. You can benefit the planet so much just by preserving the animal inhabitants and letting them do their crucial work to keep our globe safe and beautiful.
