We only have one Earth, and if we don’t take care of it, terrible things can happen. Our land and water are under attack from a variety of different sources, and without intervention, future generations might not have enough food to eat or clean water to drink.
Technology makes our lives so much easier, but it has taken its toll on our environment in a variety of different forms. Factories pollute the air, which leads to the destruction of the ozone layer and acid rain. As the population of humans grows, we need more land to grow crops and to build our houses, so land degradation has been increasing in recent decades.
By teaching our children to be respectful of the planet, we can slow down many of these threats to the environment so that future generations can enjoy the same natural resources we often take for granted, such as clean air and water, along with the incredible wild animals that we share this world with.
