Informative speech about air pollution

Global Warming

Specific Purpose Statement: Why do we suffer from global warming? This is a question I will address in this work.

Central Idea: Unless all industrialized nations make a real effort to improve their waste management, global warming will continue to happen.

Introduction

Have you ever thought about how overpopulation affects our world? Over time, population on earth has been increasing. There were fewer than one billion humans living on earth 200 years ago. Today, according to UN (United Nation) calculations, there are over seven billion of us on Planet Earth. Obviously, if the population grows, our human activities will also expand. In one form or another, not only the land but also the environment can suffer important harm. The damaging consequences of over population can negatively impact species extinction, natural resources, and global warming.

To Conclude

Overpopulation harms the environment by causing the extinction of several animal species, depleting resources, and accelerating global warming. In effect, overpopulation is not only affecting our planet now but also resulting in serious consequences for the future. According to Paul Ehrlich, a famous population analyst, “If there is not a massive reduction of humans and redistribution of natural resources soon, hundreds of thousands of people will die in the future from the lack of these resources in a die-off” (2012)
