Due to the fact that it is so simple the biotic pyramid doesn't seem like it gives us much information but in reality it is what life is based on. As we learned in class it is not a hard concept to grasp. The biotic pyramid is the food chain and it shows in order how energy is transferred. This easy concept can be applied to anything involving life and it is important that we respect it and don't use technology to alter the steps in this pyramid. We need nature to survive and manipulating it can be catastrophic.
"Throughout the twentieth century it was considered that substitutes could be found for resources supplied by biodiversity: renewable sources of energy -wood and animal energy- could be replaced by fossil fuel; manure for growing food could be replaced by the products of fertilizer factories; and medicines could be made from synthetic molecules. But fossil fuels have given us climate change; agrichemicals have threatened species, undermined soil fertility and human health; and synthetic drugs have had fatal side- effects."
There is no way to beat nature. We must play by the environments rules because we need it to survive. Although manipulating the natural environment may sometimes turn out in short term success things will always fail in the long run. As Shiva has shown us, everything that we humans have done to cheat the environment is beginning to backfire. Things like fossil fuels seemed to work for many decades, but we have recently began to see the dreadful side effects such as pollution and climate change. We must not lose sight of the biotic pyramid and learn to follow its steps exactly without manipulating the environment.

"The extinction of a species means not just the loss of that particular species, but also a threat to the other species that are supported by it through ecological process."

Once again we go back to the importance of the biotic pyramid. If you alter even one of the stages of it they will all be negatively affected. The vegetation require the microbes, the animals require the vegetation, and the humans require the animals. All of these are required for life to exist and if any of these are removed the rest would go extinct.
"Biodiversity is not just a conservation issue, it is an issue affecting economic survival."

Most of the time when ecological issues are brought up there is a large amount of people who are not concerned with it but only care about money. The thing about biodiversity is it involves both so everyone is affected. Everything we have today comes from nature one way or another and if we neglect and mistreat the environment parts of it can go extinct that we require to make things. This will remove items from circulation which would for sure hurt the economy.
