Many anmal habitats are being destroyed because of human urbanization.The Earth is an essential environment for humans since it is our resource for good supply, our energy source, our source for recreation, our source of medicine, and our natural resources for industrial products. We Humans are so heavily reliant on the Earth for survival that I could say the Earth is our "steward." Since the dawn of man our human interactions with nature has always been disruptive. Today, humans amazingly have an astronomically greater affect on the Earth than it did before. The effect is so great that we are even able to threaten the lives of all the living creatures in the world. But... why?
The reason is because Human's are naturally greedy creatures we're never content with what we have and strive for better no matter the cost. The Earth is our steward and the Aborignals of Canada realized this and lived as a part of nature rather than it's steward. For example the Aboriginals we're nomadic people following the buffalo instead of capturing and harvesting animals as we do now, and they did their best not to waste anything. If we could rewind time and decide to adopt their principles instead of trying to colonize them like we had, the world would be far better off.
Living in a house, sleeping on a bed, facebooking, watching televion, driving cars, listening to our iPODs, getting food from our fridges, turning up our heaters during the winter, these are things we do thoughtlessly. It is these things in life that we do so carelessly that are the main reason for our Earth's current condition. We all live in some sort of house, but do we realize what it took to make the home? It would take harvested wood from a forest which destroyed the habitat of bugs, birds, and etc. Heavy machinery would require gasoline which would release CO2 into the atmosphere and eat away at our ozone layer increasing the Earth's tempurature. The food we buy is all so excessively packaged which we throw in the garbage which either gets preoprly disposed of or gets thrown into our ocean.
Scientists estimate that there is approximately 1.8 million named species in the world and an estimation of 2 million - 50 million species living today. However due to human's disruptive interactions with the Earth, species' extinction rate has approximately increased 100-1000 times than before. The main reasons for this are because of deforestation, urbanization, over fishing, mining, and the many little things we do everyday without a second thought. We Humans are rapidly increasing our population by the billions as the animal population declines.
Tropical deforestation is responsible for approximately 20% of world greenhouse gas emissions. According to new research led by a University of Colorado at Boulder geophysicist, a giant asteroid that hit the coast of Mexico 65 million years ago probably incinerated all the large dinosaurs that were alive at the time in only a few hours, and only those organisms already sheltered in burrows or in water were left alive. 20,000 years ago ice covered the land wiping out almost all life on the eartth, this period is known as the ice age. All of these naturally occuring disasters have drsatically changed the surface and life on earth. Time and nature has changed the world in many significant ways, but humans have definitely changed it the most. Humans are able to survive throughout many hardships as the sands of time flowed through the hourglass, but now we have created a disaster we may possibly not survive. If humans were "stewards" of the world, we'd definitely be a terrible one.
A meteor hitting the earth could wipe out all live as we know it, but humans are capable of destroying the world over 7 times over. Are we good stewards?
