sustainable development pros and cons

The goal of sustainable development is to meet people's current needs of the present without compromising the ability of future generations to meet their own needs. Many of the current processes by which we as a modern world choose to obtain and use our natural resources are short-sighted. Companies looking to make a profit right away can cause long term damage to the environment when they do things like cut down too many trees, overfish, or produce pollutants.
Sustainable development has the optimistic goal of disturbing as little as possible on land, at sea, and in the air so that humans have a smaller impact on he environment. There reasons why developing production methods that are sustainable benefits the whole world. Polluted rivers, global warming, and the deforestation will have a tremendous negative impact across the world if nothing is done to stop this destruction. Sustainable development hopes to find renewable and climate-friendly sources of food and energy, leaving the Earth clean, and protecting thousands of species of animals across the world.
However, the biggest problem with sustainable development is that it will take years for cleaner and better practices can be employed all over the world. An immense amount of research has to be done in order to find out which methods of production damage the environment the least. When one method of sustainable development is first tried out, the initial results are often disappointing. Finally, it will cost a tremendous amount of money up-front to do the needed research and built the new eco-friendly manufacturing plants, which is one reason that many people are hestitant to support sustainable development.
