Some people believe that the earth is being harmed by human activity. Others feel that human activity makes earth a better place to live. My opinion is that people are harming the earth more than helping earth becoming a better place. Human activity is harming not only the earth but the living habitats of animals and people as well. Our planet earth is being affected by global warming. Many scientists have proved the harm from global warming has increased over the years. The most obvious harm is the higher sea levels. Global warming cause the temperature to rise, there will be more hot weathers. These can cause disasters such as storms, heat waves, and acid rainfall. The warmer climates melted many ice caps which are increasing the sea levels. The water is reaching these lands and flooding them over. Many places in the coasts around the world, will disappear if this happens, places such as Shanghai, Holland, San Francisco, Florida. This brings many other problems such deaths and many diseases from food. Another main negative effect is the bad life conditions that many parts of the world will suffer. These bad life conditions may be starvation and deaths due to short food supplies. Human health will be decreasing because of the air pollution in our environment, and will cause problems such as allergies and asthma. By make more land for houses people start to cut down trees. Cutting down trees can cause many to lose their habitats. Tree roots cannot hold the soil in place and absorb water from the soil making the soil harder to store water which cause flooding. Some people believe that the earth is being harmed by human activity. Others feel that human activity makes the earth a better place to live. Human are trying to help the earth by recycling, but we are mostly just trying to repair what we damaged not really actually helping the earth. It seems to me that human activity is causing more harm than good.
