Why should we take a stand on environment ? worthy to read?
All humanity should take a stand on environment because is an issue that’s affects us every single day and is already causing big effects around the entire world. We, humans have cause a great damage to our own environment, and now it is time to fix it. The increase of human activity in the past years is destroying our ecosystems, and plants are animals are becoming extinct. Environmental conditions are changing so quickly that individual species as well as entire ecosystems are struggling, and often failing, to adapt. Land use is one of the biggest factors affecting the decrease of biodiversity. About one quarter of the Earth's surface is covered by farm land, a problem that is often overlooked. The most fertile soil is usually found in the best climates, which also usually happens to be where the largest amount of biodiversity is. The best example of this is in the tropics, where both tropical rainforests and cloud forests are being cut down and turned into "patchwork" farms. Fertilizers and pesticides used to treat crops harm land and drive animals away. Eventually, a given plot of farmland will contain too many chemicals to continue farming on, and the farmer will have to move to a new one, creating a vicious cycle of destruction of natural land. Extinction is another big favor; we are reducing habitats to the point where animals can no longer live. The dramatic disappearance of many species is now happening very quickly. Pollution and toxification; is a mayor concern even at low levels, because they can affect entire ecosystems through the chain of life. Furthermore, pollutants in soil and ground water cannot travel quickly, and thus do not filter out well. Reproductive anomalies in animals, especially frogs, are being attributed to pollution and toxification, and some scientists fear that these could eventually affect humans. For these reasons, it is very important that we protect biodiversity and the natural environment. The problem in this issue is that humans don’t realize the damage we are doing, we are not aware. Why should we destroy something that keeps us healthy? We are healthy because of the goods we obtain from nature. We obtain food; animals and vegetables that keep us healthy. We obtain cloth; cotton from plants and animal skin. And we obtain medicines that are derived form natural existing resources. Not only that but nature himself helps us in their own ways; tress and plants keep air clean through the constant transfer of carbon dioxide and oxygen, nature also helps us keep water clean and naturally manages water flow and watershed.
