supplies. Rainforests provide a home to many species of plants‚ both known and unknown. Our dependencies on tropical plants are vast ranging from the daily essentials of food and shelter‚ to cures for cancer and possibly AIDS. As destruction of the rainforest continues‚ the effects on plants are immense through the loss of genetic diversity and the disappearance of species. Plant species extinction is reaching critical levels. With this extinction comes a cascade of effects on the ecosystems in which

Abstract Global warming is a direct result of human activities on this planet. Our species have inhabited this planet for thousands of years but only since the 1900’s have scientists been able to measure the changes that we have induced on earth. It is estimated that temperatures have risen globally by about 0.9 degrees Fahrenheit‚ which may seem minor‚ but have caused physical changes on the planet (and potentially dangerous ones in the future). The “greenhouse effect” is a term many politicians

What is the main cause of global warming? In the last century‚ the sea level has rose for about 17 centimetres. The rate in the last decade is however‚ nearly the double of last century. Major global surface reconstructions also showed that the Earth has warmed since 1880 and it’s still going on. Oceans are also warming up‚ due to the heat. Not only that‚ the Greenland and Antarctic ice sheets are melting‚ glaciers are disappearing and extreme weather events have occurred more often. All these

Global Warming Essay Global warming is one of the greatest challenges for the environment. It is the increase in the temperature of the Earth. There are several things happening now that demonstrate global warming as directly impacting the rising of sea levels‚ the melting of ice caps and significant worldwide climate changes. Unfortunately‚ the imbalance which has been created between life and earth is already showing the signs of disaster in forms of floods‚ cyclones‚ landslides‚ tsunamis and

Global Warming: The Causes‚ Effects and the Human Influence Global warming refers to the rise in temperature of the earth’s surface. There exists an intricate ecological balance within the earth’s atmosphere. Slight increase in the temperature of the earth’s surface creates a serious ecological imbalance with far reaching consequences on earth’s aspect of life. The activities that contribute to such a change on earth are much likely attributable to humans. Earth is being effected highly by green

Global Warming Global warming is the most pressing challenge facing the world today. After examining what global warming is‚ I have realized that human activities have a large impact on how the earth’s surface temperature is due to the greenhouse effect. I also have realized the impact that global warming can have on the earth. We as human’s need to do what we can to lower our contributions to the global warming before it is too late.
