The earth is a planet with extreme variation in bio-diversity, geography, and climate. It is the only known planet to support intelligent life, and is a place that all human beings call home. Since the dawn of time, humans have relied on the planet around them, both land and sea, to provide them with resources and food. Often, people tend to forget that it is not just their home, but is also home to millions other different species of animals as well, and home to an even greater number of plant species. This is in terms of terrestrial, land-dwelling life. In terms of aquatic life, researchers know very little of what is potentially in our earth’s waters. However, it is safe to say that it may be even more diverse and numerous than what lies above the surface of the oceans and lakes, considering oceans cover about 75% of the earth’s surface. Consequently, with all the life on earth, natural competition and selection takes place between everything to determine who and what lives and dies, including human beings. The problem is this; humans have taken the “natural” out of “natural competition”, because they do not extract and use their resources in a natural and sustainable way. We humans, degrade and take horrible care of our planet. The degradation of earth is caused by many human factors. Today I am going to talk about 3 of them. First I will talk to you about deforestation. Next I will talk to you about Ocean pollution. Last, I will talk to you about overfishing. Each brings its own unique onslaught of problems. Each provides just another way in which the earth can become less beautiful. In the Oceans and on land, there is an abundance of diverse life, especially the rainforest. Sciennected says the rainforest is home to approximately 70% of the world’s animal species and 25 % of the world's medicine is derived from rainforest plants. Unfortunately, deforestation is clearing Earth's rainforests, which according to national geographic, cover about
