for most of the developing countries, it is a good idea to control the population growth. for example, china has carried out birth control for years. and this plan has a GREat effect on the world population.
if the population continues to increase, if the air and water continue to be polluted, if we dont do something to protect wild-plant and wildlife species will be declining. species and biological communities have difficulty adapting to change. economic opportunities and the quality of life of future generations are also put at risk. by protecting nature, we protect ourselves.
lets unite together, hand in hand we stand all across the land.
we can make this world in which to live. hand in hand. control the population growth. take good care of our nature.
