I am not convinced that technology alone can solve all of our environmental problems. It seems likely that we will need to alter our behaviors to at least some degree if we wish to avoid excessive harm to the environment.
Right now, the greatest environmental challenge we face is that of global warming. Technology can clearly be very important in solving this problem. For example, the massive wind turbines that we see in so many places in the United States are a way in which technology is helping to solve the problem. So too are various technological advancements such as hybrid engines that are reducing the amount of fuel that cars need in order to run. If we can continue to innovate in ways like this, we can reduce our consumption of fossil fuels even more than we have.
However, technology cannot be the complete solution. It is also necessary for us to change our habits to some degree so that we can reduce our fossil fuel consumption more rapidly. For example, it is important for us to reduce the amount of electricity that we use. It is also important for us to bike or walk or take public transit when we can to reduce our “carbon footprint.”
I would argue that technology can be very helpful in solving our problems, but that it cannot make enough of a difference to solve the problems completely.
