I think that a major emphasis on conservation along with recycling is going to be the only way. As mentioned above the number of people is not going to decrease, therefore more people will be consuming both renewable and non-renewable resources.
This is from a strictly North American perspective as Americans are the biggest group of consumers in the world. We need to reduce consumerism, and we need to stop producing, selling, and buying disposable products. Industry and all the commercial and consumer by-products are in large part responsible for damage to our planet.
I think that technology is the only answer. We need to have more people be able to subsist while using less energy and having less of an impact on the Earth.
The number of people is not going to decline. People are also getting richer and will want to consume more. Therefore, we must have better technology (especially ways to make things that use less energy) so that we will be able to produce the things that people want without ruining the environment.
On one level, I think that conservation attempts have to be bolstered by a revisiting or assessing conservation ethics. The practices of why we conserve what we conserve and seeing them in a larger context is of vital importance to the maximization of conservation attempts. Ensuring that there is a thoroughly examined position of ethical biodiversity can help to bring this goal into fruition. At the same time and along these lines, the goal of sustaining biodiversity has to be approached on both "deep" and "shallow" levels. This refers to the targets of biodiversity action. In regards to the former, one has to approach the problem from socio- economic levels. This means that our current practices in both political legislation and economic reality have to be concurrent with sustaining biodiversity and conservation techniques and practices. It might mean rewarding organizations and companies that enhance these values and reprimanding those who do not. On a "shallow" level, individuals on a grass roots type of foundation have to fully grasp why conservation and protection of biodiversity is important, attempting to bring its meaning out in their own lives and daily practices.
in my opinion, i think that oil should be restricted and all of the renewable sources should be used in alliance, some argue that wind power doesnt generate enough energy and can be ugly, but when allied with tidal power and solar power you can cut down the amount of wind farms and also create more energy.
